Air Pollution: Ewg's Fight For Clean Air

The Environmental Working Group (EWG) is a nonprofit, nonpartisan organization that helps people live healthier lives. EWG has identified that air pollution is not just caused outdoors but also indoors, where there can be two to five times more air pollution than outdoors. This is due to chemicals that come into homes uninvited through furniture, dust, sprays, paint, and other household products. These household products emit volatile organic compounds (VOCs) and contribute to half of the VOCs that cause air pollution. EWG provides guides to help people avoid products with VOCs and recommends tough health standards backed by a scientifically valid system of airborne particulate monitoring.

The Environmental Working Group's (EWG) stance on air pollution

The Environmental Working Group (EWG) is a nonprofit, nonpartisan organization dedicated to helping people live their healthiest lives. Founded in 1993 by Ken Cook and Richard Wiles, the EWG is headquartered in Washington, D.C. and has since grown into a community 30 million strong. The group advocates for organic food and farming and has been influential in raising awareness about the potential health risks associated with contaminants in our food, water, and everyday products.

One of the key focuses of the EWG is air pollution, specifically particulate air pollution. The EWG has criticized the use of statistical techniques, such as spatial averaging, that can skew monitoring and create the illusion of clean air in a particular area. Instead, they recommend tough health standards backed by a scientifically valid system of airborne particulate monitoring. The group has identified "sacrifice zones," where residents continue to breathe unhealthy air because it is averaged with cleaner air from elsewhere, resulting in no remedial action being taken.

To address this issue, the EWG suggests maintaining current rules for monitoring and enforcement, where exceeding the standard in one location triggers a violation. They emphasize the public's right to know about pollution in the air and advocate for increased monitoring sites to ensure representative data. The EWG also highlights the need for major particulate polluters to contribute to a fund dedicated to statistically valid particulate monitoring.

Additionally, the EWG has expressed concern over the hundreds of toxic pollutants emitted into the air due to our reliance on fossil fuels. They have advocated for increasing regulations on the use of per- and polyfluoroalkyl substances (PFAS) and have collaborated with the Social Science Environmental Health Research Institute (SSEHRI) to map PFAS detections in water samples across the USA. The EWG has also published reports analyzing the safety and effectiveness of sunscreens, calling for more detailed information from manufacturers about sun protection levels.

In summary, the Environmental Working Group's stance on air pollution is one of proactive advocacy for tougher health standards, increased transparency in monitoring, and the reduction of toxic pollutants emitted into the atmosphere. They strive to empower individuals with knowledge and resources to make healthier choices and drive industry and legislative changes for improved environmental health.

The dangers of indoor air pollution

The Environmental Working Group (EWG) is a nonprofit, nonpartisan organization dedicated to helping people live their healthiest lives. EWG has been vocal about the dangers of air pollution, particularly the use of statistical techniques to hide pollution levels and avoid cleaning up the unsafe air breathed by millions.

Indoor air pollution is a serious global issue that can have detrimental effects on human health and well-being. The air we breathe indoors can be polluted by smoke, vapors, mold, and chemicals found in paints, furnishings, and cleaning products. As people in the U.S. spend about 90% of their time indoors, the impact of indoor air pollution on health cannot be overstated.

Several factors contribute to indoor air pollution. Firstly, outdoor air pollutants can enter buildings through open doors, windows, ventilation systems, and even cracks in structures. For example, harmful smoke from chimneys can re-enter homes and pollute the indoor air. Additionally, certain human activities within buildings, such as smoking, burning solid fuels, cooking, and cleaning, can release pollutants into the indoor air.

The concentration of indoor air pollutants is influenced by factors such as the air exchange rate, outdoor climate, weather conditions, and occupant behavior. Inadequate ventilation, higher temperatures, and increased humidity can further exacerbate indoor air pollution levels.

The health effects of indoor air pollution are significant and far-reaching. Both short-term and long-term exposure can lead to respiratory diseases, heart disease, cognitive deficits, and even cancer. Indoor air pollution has also been linked to impaired lung function in infants, increasing their risk of pneumonia during their first year of life. Additionally, exposure to indoor air pollutants can cause irritation of the eyes, nose, and throat, as well as headaches, dizziness, and fatigue.

Addressing indoor air pollution is crucial to protecting public health. This involves improving ventilation, reducing the use of polluting fuels and technologies, and implementing health standards backed by scientifically valid systems of airborne particulate monitoring. By taking these steps, we can mitigate the dangers of indoor air pollution and create healthier indoor environments for all.

The impact of VOCs on air quality

The Environmental Working Group (EWG) is a nonprofit, nonpartisan organization dedicated to helping people live their healthiest lives. One of the issues that EWG addresses is air pollution, particularly the impact of volatile organic compounds (VOCs) on indoor and outdoor air quality.

VOCs are emitted as gases from certain solids or liquids and include a variety of chemicals, such as perchloroethylene, formaldehyde, and organic solvents. These compounds are commonly found in household products such as paints, varnishes, cleaning agents, cosmetics, and fuels. Concentrations of VOCs are often much higher indoors compared to outdoors, with levels up to ten times higher inside homes. This is due to the use and storage of products containing organic chemicals, which release VOCs into the air.

Certain individuals are more susceptible to the harmful effects of VOCs, including those with respiratory issues such as asthma, young children, the elderly, and people with heightened sensitivity to chemicals. To minimize the impact of VOCs on air quality and reduce potential health risks, it is recommended to limit the use of products containing organic chemicals, improve ventilation by opening doors and windows, and dispose of unused chemicals properly. Additionally, it is important to follow safety guidelines and warnings on product labels, such as using certain products in well-ventilated areas.

While EWG advocates for tougher health standards and more representative monitoring systems to address air pollution, the organization also emphasizes the public's right to know about the levels of particulate pollution in their communities. EWG's recommendations aim to ensure that unsafe air is not simply averaged out statistically but is properly identified and addressed through effective pollution reduction measures.

EPA's proposed changes to monitoring criteria

The Environmental Working Group (EWG) has raised concerns about the U.S. Environmental Protection Agency's (EPA) proposed changes to air pollution monitoring criteria, specifically regarding the use of spatial averaging. While the current monitoring system has its limitations, it does identify hotspots where airborne particulates are at unsafe levels.

The EPA's proposed spatial averaging scheme aims to revise the Clean Air Act's New Source Review (NSR) preconstruction permitting program regulations. The EWG argues that this scheme could skew monitoring by creating "sacrifice zones" where unsafe air is not cleaned up but is averaged with cleaner air to create the illusion of clean air within a zone. The EWG emphasizes the need for scientifically valid particulate monitoring and recommends maintaining the current rules where exceeding the standard in one location triggers a violation, ensuring pollution reduction measures.

The EWG's analysis of data from state and local air monitoring stations (SLAMS) and national air monitoring stations (NAMS) supports their concerns. They identified potential "sacrifice zones" where residents would continue breathing unhealthy air without any remedy initiated. While the EPA suggests that the proposed 24-hour standard would protect against these zones, the EWG emphasizes that monitoring and spatial averaging must be done scientifically and statistically validly, focusing on identifying and cleaning up unsafe areas rather than merely appearing clean statistically.

The EPA's proposed revisions also include expanding monitoring, record-keeping, and reporting requirements, which could result in delays for projects and expansions. The revisions would impact serious, severe, and extreme nonattainment areas, aggregating emissions increases over five consecutive years to determine a significant net increase. Additionally, the EPA proposes to clarify the "reasonable possibility" provisions for projects at major stationary sources, evaluated using the actual-to-projected-actual applicability test.

Overall, the EWG advocates for tough health standards and a scientifically valid monitoring system. They recommend that major particulate polluters contribute to a fund administered by local air quality officials to support valid particulate monitoring in metropolitan areas.

The creation of sacrifice zones

The Environmental Working Group (EWG) is a nonprofit, nonpartisan organization that helps people live their healthiest lives. It has identified 35 counties that contain potential "sacrifice zones", where unsafe air is not cleaned up and is instead averaged with cleaner air from elsewhere to create the illusion of clean air.

Sacrifice zones are places that are given up for the "greater good" of society. They are the result of environmental racism and injustice, with people of colour being more likely to experience polluted air and groundwater. This is due to practices like redlining, where racial minority groups are limited to certain areas, and corporations take advantage of their lack of political power to site polluting facilities. As a result, individuals in sacrifice zones suffer from health issues such as asthma, respiratory problems, cancer, and heart disease, as well as mental health problems associated with feeling exploited and stigmatized.

One example of a sacrifice zone is "Cancer Alley" in Louisiana, which is home to over a hundred oil refineries and petrochemical plants located in poor, predominantly Black communities. Similarly, in Massachusetts, BIPOC communities are exposed to more air pollution than white communities, with areas like the Fore River Basin and Chelsea being identified as sacrifice zones.
