GENERAL ANNOUNCEMENTS

 

IAQ Bills Pending in California Assembly

In the current session, there are two Assembly Bills that address indoor air quality issues:

 

 

 

AB 2276 has passed the Assembly Floor vote, and it is yet to be scheduled for hearing in the Senate. AB 3018 is in suspense in the Assembly Appropriation Committee. Unless it passes out of committee to allow a floor vote, it will die in the Assembly.

 

June 2nd is the last day for a bill to pass out of its house of origin, and the legislature starts it recess in July. Because the time is short, it is important that groups and individuals immediately direct their concerns and/or support to the bills sponsors and the house leadership.

Exposures to cleaning product chemicals and pollutants formed by reactions with ozone
        Brett Singer

Indoor Environments Division, Lawrence Berkeley National Laboratory

 

Presentation is available on-line at

 

 

When cleaning products and air fresheners are used indoors, occupants are exposed to airborne chemicals, potentially leading to health risks. Indoor air pollutant exposures owing to cleaning product and air freshener use depend on emissions from products, dynamic behavior of chemical species, and human factors.

 

A series of experiments was conducted to investigate volatile organic compound emissions, concentrations, and reactive chemistry associated with the household use of cleaning products and air fresheners. Research focused on two common classes of ingredients in cleaning products and air fresheners: ethylene-based glycol ethers, which are classified as toxic air contaminants, and terpenes, which react rapidly with ozone. A shelf-survey of retail outlets led to the selection of 21 products whose chemical composition was characterized. Among the criteria used to select these products were ready availability through California retail outlets and, for the majority of products, expectation that they contained ethylene-based glycol ethers, terpenes and related compounds, or both.

 

Of the 17 cleaning products characterized, four contained substantial levels of d-limonene (4-25% by mass), three contained terpenoids that are characteristic of pine oil, six contained substantial levels of ethylene-based glycol ethers (0.8-10% by mass), and five contained less than 0.2% of any of the target analytes. Xylene in one product was the only other toxic air contaminant detected. Among the four air fresheners characterized, three contained substantial quantities (9-14% by mass) of terpene hydrocarbon and terpene alcohol constituents, with linalool being the most abundant. Six of the 21 products were investigated in simulated-use experiments in which emissions and concentrations of primary constituents were measured. Cleaning products that contain 2- butoxyethanol as an active ingredient produced one-hour-average concentrations of 300 to 2,300 micrograms per cubic meter immediately after simulated typical use in a room-sized chamber. For cleaning products that contain d-limonene as an active ingredient, corresponding levels were 1,000 to 6,000 micrograms per cubic meter. Application of a pine-oil based cleaner produced one-hour-average concentrations of 10-1300 micrograms per cubic meter for terpene hydrocarbons and terpene alcohols. Reactive chemistry was studied by exposing constituents of three products to ozone, both in a bench-scale chamber and during simulated use. Prominent products of the reaction of terpenes with ozone included formaldehyde (a toxic air contaminant), hydroxyl radical, and secondary organic aerosol (a form of fine particulate matter).

 

Incorporating the new experimental data, exposures were estimated for several simulated use scenarios. Under ordinary circumstances, exposures to 2-butoxyethanol, formaldehyde, and secondary organic aerosol are not expected to be as high as guideline values solely as a result of cleaning product or air freshener use. However, ordinary use could lead to exposure levels of similar magnitude as guideline values. Scenario model results suggest that exposure levels could exceed guideline values under exceptional yet plausible conditions, such as cleaning a large surface area in a small room. The results of this study provide important information for understanding the inhalation exposures to certain air pollutants that can result from the use of common household products.

Environmental Tobacco Smoke Identified As Toxic Air Contaminant

The California Air Resources Board formally identified environmental tobacco smoke (ETS) as a Toxic Air Contaminant at the January Board meeting. The identification was based on a report that was prepared jointly by OEHHA and ARB, and approved by the Scientific Review Panel, an external advisory panel. The report updated estimates of lung cancer deaths, other cancers, and many other adverse effects, and provided new estimates for breast cancer. The report also presented important outdoor monitoring results for ETS exposure at locations such as the airport and an amusement park where smokers gather. As with other toxic air contaminants, ARB staff will now consider whether further actions are needed to address ETS.

 

New Fact Sheet On Ozone Generators

ARB has just released a new fact sheet on ozone generators ─ indoor air cleaners or air purifiers that purposely emit ozone. These purported air cleaners do not clean the air as advertised, and in fact can produce indoor ozone levels equivalent to a stage 1 smog alert in the home. Ozone not only irritates the respiratory system, but it can cause permanent lung damage, and can exacerbate (and possibly cause) asthma. The fact sheet was developed as part of a new ARB outreach program just getting underway to inform medical professionals, retirement groups, asthma and allergy organizations, and many others about the dangers of ozone generators. The fact sheet, along with an updated list of ozone generators sold as air purifiers, can be found on-line at

 

CEC-ARB New Homes Field Study: Pilot Study Completed

A pilot study was conducted in three Sacramento area homes in November-December as part of the Ventilation and Indoor Air Quality in New Homes field study. ARB and the California Energy Commission are collaborating on this study to assess the ventilation characteristics and indoor air quality (IAQ) of over 100 new single-family detached homes in California. Three teams of contractors, at times accompanied by ARB employees, sequentially visited each home. On the first day, Team 1 recorded physical home characteristics; placed logs for the use of windows, doors, and appliances; installed data loggers on appliances, windows, and ventilation equipment; and tracer gas emitters for air exchange rate measurements. After one week, Team 2 inventoried indoor sources (e.g., building materials, carpeted area, moisture signs), installed an air quality sampling rig both indoor and outdoors, and placed air exchange tracer gas samplers. IAQ measurements included VOCs, aldehydes, PM2.5, NO2, CO, temperature, and RH over a 24-hour period. One day later, Team 3 shut down and collected all of the monitoring equipment and performed an array of home ventilation and leakage measurements, including blower door and fan flow rate tests. The results from this pilot study will be used to refine protocols for the main field study that will begin in the summer of.

Also in December, the Board approved an Augmentation for this study. The primary additions are an improved method for measuring air exchange rates, and sampling of eight more homes with mechanical whole-house ventilation systems.

 

Environmentally Preferable Products Task Force

ARBs Indoor Program staff are active participants on the CIWMB-DGS Environmentally Preferable Products (EPP) Task Force. The Task Force wrapped up a lightning speed effort in December to develop the first set of specifications for EPPs, which are now in a Best Practices Manual on the web . The specifications provide guidance to all state procurement officers and others for selecting green products, i.e., those that are energy-efficient, resource efficient, and healthful. A few of the chapters with ARB input include cleaning products, office furniture, ink, paints, and carpet. New specifications will be developed in for additional products.

 

Workgroup to Develop Standards for Recycled Paint

Dorothy Shimer is participating in a national effort to develop environmental and performance standards for recycled paint. The Product Stewardship Institute (PSI) is a non-profit organization heading the effort. The Paint Product Stewardship Initiative (PPSI) began in, but has just recently pulled together a group of stakeholders to provide comments on standards for latex paint. Funding is provided by the California Integrated Waste Management Board, Portland Metro Regional Government, and Dunn-Edwards Corporation.

Preliminary tests indicate reprocessed paints (50% or more post-consumer content) passed performance tests. During the , recycled paint averaged 150g/L VOC, somewhat less than the California standard of 250 g/L VOC. It is expected the VOC content will always be under the California limit due to VOC evaporation during use, storage, and recycling.

 

Updating the Indoor and Outdoor Air Criteria for New Schools

Tom Phillips participated in several meetings of the Technical Committee of the Collaborative for High Performance Schools (CHPS) to update the Best Practices Manual for K-12 school design. His comments focused on the manual sections dealing with reducing indoor air pollution from building materials and construction activities, reducing noise in classrooms, reducing emissions from diesel school buses, and siting schools away from roadways and other outdoor pollutant sources. Californias Division of the State Architect recently recommended CHPS as the green building guideline for California public school construction and renovation.

 

Building Ventilation and Energy Standards Workshop

Tom Phillips attended a public workshop on potential revisions to state energy efficiency standards for the design of nonresidential buildings. The California Energy Commission held the workshop, the fourth in a series that will lead to revised residential and nonresidential building standards in. Three proposed revisions that may affect ventilation and indoor air quality (IAQ) were outlined; they would all be optional compliance credits rather than requirements:

Natural ventilation (operable windows and no exhaust ventilation or air-conditioning), only in mild-climate coastal areas in office and school buildings.

Displacement ventilation, and underfloor air distribution. These two approaches both supply fresh air at or near the floor level, relying on thermal stratification to achieve more efficient temperature control and pollutant removal in the occupants breathing zone.

Fault detection and diagnostics (FDD), and building performance monitoring systems.

 

Study to Measure Ultrafine Particles in Schoolrooms and Residences

At its December, meeting, the Air Resources Board approved a study that will be conducted by Dr. Bill Nazaroff at UCB to measure UFP and related pollutants inside California schoolrooms and residences. The study will provide information on the infiltration of outdoor UFP to indoor environments near major roadways, as well as in urban environments not close to major roadways. Investigators will also assess the influence of indoor sources on indoor UFP concentrations, including gas-cooking appliances, candles, and cleaning products that react to produce secondary organic aerosols. Investigators will use a miniature version of water-based condensation particle counters recently developed by Suzanne Hering (Aerosol Dynamics). Knowledge of ultrafine particle (UFP) concentrations in indoor environments is limited despite implications for adverse health effects associated with these particles.

Report to the Legislature on Implementation Status of the Toxic Mold Protection Act of. The report, authored by Sandy McNeel, Janet Macher and Jed Waldman, addresses the first of the SB 732-mandated tasks listed above, specifically, that DHS scientific staff consider whether it is feasible to adopt permissible exposure limits (PELs) for indoor mold. After considerable research into this issue, DHS scientists concluded that although recent studies have strengthened the evidence between living or working in a damp environment and increased risk for respiratory symptoms, the role of mold growth in these complex environments is still unclear. Damp buildings also encourage the growth of bacteria, dust mites and cockroaches, as well as degradation of wet building materials that can also release irritant chemicals indoors. Some or all of these chemicals or biological organisms may contribute to occupant illness. For these and other reasons detailed in the report, science-based PELs for indoor molds cannot be established at this time. The report is available on-line at https://www.cal-iaq.org/MOLD/SB732update.htm.

Tire Derived Flooring Study

Development of markets and alternative uses for waste tires is a major effort for the California Integrated Waste Management Board (Board) and has large environmental benefits. In, the Board sponsored the Building Material Emissions Study (published in), which measured the chemicals off-gassing from resilient flooring products made with recycled tires, among other products. The study found that indoor uses of tire-derived flooring had the potential to cause exposures to several chemicals of concern above State air toxics guidelines. These findings led the authors to conclusion: further refinement and testing of rubber-based resilient products is necessary before these products can be promoted for wide use in most indoor environments.

In, the Board funded the California Office of Environmental Health Hazard Assessment (OEHHA) to better characterize the chemical emissions from resilient rubber based products and to develop specific Indoor Reference Exposure Levels (iRELs). The iREL is intended to serve as health standard for chemicals emitted indoors posing the greatest public health threat. It is the concentration of a chemical that is safe to be exposed to for eight hours or for a longer period of time if appropriate.

To help guide in the selection of new health-based iRELs for chemicals emitted from tire-derived rubber products, additional emissions testing research was funded as a subcontract to OEHHA. The study was supported by an OEHHA Contract to the Public Health Institute, funded as part of CIWMB Contract Number IWM 03082, total contract amount $400,000 pursuant to Government Code section 7550. This final report is submitted in fulfillment of the contract requirements.

The project was conducted by the California Department of Health Services, beginning in and ending in the spring of. The research was conducted within the Indoor Air Quality Section of the Departments Environmental Health Laboratory Branch. Substantial in-kind support for staff, equipment, and supplies, was provided by the Department of Health Services.

The primary goal of this laboratory study is to identify and quantify volatile organic compounds (VOCs) emissions of from resilient flooring made with recycled tire materials. Our primary focus is to evaluate tire-derived rubber (TDR) resilient flooring products that are, or can be, used indoors. In an indoor setting, the VOCs emitted from these products may result in chronic inhalation exposures or acute irritancy for occupants. This report will identify chemicals emitted from TDR flooring that may cause exposures at levels of health concern.

Prior emissions testing in this laboratory relied on a standardized screening protocol used in the BMES: a 10-day conditioning period followed by a 4 day testing period, with reportage of emissions at 14 days. In order to ascertain VOC emissions over time for the current study, protocols were developed to extend the test period to 90 days. An additional goal is to repeat tests on the same products manufactured at different times to help characterize the variability in these products and the reliability of emission screening. Finally, the current study extends analytical limitations of the BMES by attempting different techniques to analyze gas chromatograph/ mass spectrometer chemical peaks that were previously unidentified.

This laboratory study also supports the California Office of Environmental Health Hazard Assessment (OEHHA) in their activities to better characterize the chemical emissions from resilient rubber based products and to develop four specific Indoor Air Reference Exposure Levels (iRELs).

In conducting the current study, we successfully acquired a wide range of TDR and non-TDR resilient flooring products to learn about product emission rates of VOCs. The study also solicited replicate samples manufactured in different times to see how rates varied for different production lots. Under this study, we developed an extended protocol for short-term and long-term conditioning and chemical emission testing, which started with the 14-d protocol, and extended to 90 days.

Three compounds (benzothiazole, methyl isobutyl ketone, and cyclohexanone) were emitted at substantial rates for most flooring products tested. For most products, emissions for these compounds were 75% or more of TVOCs released. However, there was a large amount of an unidentified compound in a small subset of products, plus one Indoor/Exterior paver with substantial emissions of aliphatic hydrocarbon compounds. We had limited success in identifying previously unresolved GC/MS peaks, although we were able to determine many of these compounds by their chemical classes.

TVOC emission rates were generally high, leading to potential room concentrations from 500 to several 1000 mg m-3 h-1. For the products acquired from different production lots, most of the major emission constituents were consistent. Chemicals of health concern were absent or emitted at low rates in most products. Xylenes and acetaldehyde were found in a range of products, while benzene and carbon disulfide were found at potential hazardous levels in just one or two samples. Contaminants seem to be due to minor constituents in the manufacturing process, since they were sometimes found in one production lot and not another.

Emission rates were noted to decline over time fairly rapidly the half-life of compounds (i.e., the time to drop to half of its initial rate) ranged from ~5 days to ~40 days. The decline of benzothiazole, methyl isobutyl ketone, and cyclohexanone emission rates (as well as TVOCs) were slower than for the more volatile minor constituents, e.g., Acetone, Acetaldehyde, and Benzene. In terms of long-term chemical exposures to room occupants, these toxic compounds are largely depleted in the first 2-4 weeks following installation. However, the major TVOC constituents persist, and as much as 25% of long-term exposures can remain after the initial flush-out period.

Environmentally Preferable Purchasing (EPP)

The Governors Action Team EPP Task Force has completed about half of its Best Practices Manual (available at: ). It will also participate in Department of General Services procurement teams developing new specifications for several upcoming state contracts.   

 

At the March 29 meeting Craig Sheehy of Thomas Properties (responsible for facility operations at Cal/EPA) gave a presentation about the successful use of green cleaning products in the Cal/EPA building in downtown Sacramento.  They tested green cleaning products in 10 buildings in northern California and selected to use the best performer, as judged by custodians.  A Johnson Diversey product with hydrogen peroxide was selected: Alpha-HP Multi-Surface Cleaner , along with a glass cleaner and disinfectant (all hydrogen peroxide based).  Craig also has anecdotal information about reduced workman compensation cases and overall building operations savings.  He pointed out that the green cleaning products do not cost more.    At the meeting, Prison Industry Authority, which manufacturers cleaning products, said they were interested in developing a green cleaning product line and have a contract starting soon that will look at new formulas.  Green cleaning products that meet the Green Seal 37 criteria can earn points in LEED for Existing Building rating system.  It is state policy for buildings over 50,000 square feet to be LEED EB certified so we anticipate an increase in the use of green cleaners.

Polybrominated Diphenyl Ethers (PBDEs): Recommendations to Reduce Exposure

The manufacture, distribution and processing of products containing pentabrominated diphenyl ether (pentaBDE) and octabrominated diphenyl ether (octaBDE) flame retardants will be prohibited in California as of June 1, (California Health and Safety Code Sections 108920 et seq.); only products manufactured after June 1, are subject to the prohibition. This prohibition was prompted by findings that exposures to polybrominated diphenyl ethers (PBDEs) are widespread, and may pose health risks. However, the manufacture, distribution and processing of products containing the most commonly used PBDE mixture, decabrominated diphenyl ether (decaBDE), has not been prohibited. PentaBDEs and octaBDEs are ubiquitous and Californians will continue to be exposed to them after June 1. On May 27 the Cal/EPA Secretary directed the formation of a workgroup of representatives from Cal/EPA Boards, Departments and Office (BDO), and DHS to consider the nature and extent of the PBDE problem and to recommend actions Cal/EPA could take to mitigate exposures to reduce risks of potential PBDE health effects. This report was prepared in response to the Cal/EPA Secretarys directive. The principal focus of this report is to address continuing exposures of Californians to PBDEs after June 1.

Environmental Tobacco Smoke (ETS) as a Toxic Air Contaminant (TAC)

The California Air Resources Board (CARB) identified ETS as a TAC on January 26, based on reports by OEHHA and CARB staff and findings of the Scientific Review Panel (SRP) on TACs. The report on health effects of ETS prepared by OEHHA staff describes a number of adverse health effects, including several specific to infants and children, or to which infants or children may be especially susceptible. These include low birthweight and decrease in birthweight, Sudden Infant Death Syndrome, pre-term delivery, acute lower respiratory tract infections, asthma induction and exacerbation, chronic respiratory symptoms, and middle ear infections. ETS exposure is also associated with increased risk of cancer. Infants and children exposed to carcinogens experience a greater risk of cancer later in life, compared to the risk experienced by those exposed as adults. Further details are provided in the staff report, which is available at

Accordingly, OEHHA formally adds ETS to the list of TACs, which may cause infants and children to be especially susceptible to illness. See the following memorandum:

Listing of 2,4-D Acetic Acid and Related Compounds As Reproductive Toxicants

OEHHA has received requests from interested parties seeking further extension of the comment period to allow for the submission of complete and relevant scientific information. OEHHA has extended the public comment period for (2,4-dichlorphenoxy) acetic acid; 2,4-D n-butyl ester; 2,4-D isopropyl ester; 2,4-D isooctyl ester; propylene gylcol butyl ether ester (of 2,4-D); 2,4-D butoxyethanol ester; and 2,4-D dimethylamine salt to Monday, March 20,. 2,4-D products are herbicides used to target weeds and are frequently used in broadcast and spot treatment on turf. They are often found in house dust, which may be treaded into homes by children and adults after the herbicides were applied on lawns.
