Consumer Goods: Air Pollution's Unseen Culprits?

A recent study has found that emissions from common household and industrial products, such as perfumes, pesticides and paints, now rival motor vehicle emissions as the top source of urban air pollution. This is surprising, as people use a lot more fuel than they do petroleum-based compounds in chemical products. However, lotions, paints and other products contribute about as much to air pollution as the transportation sector does.

Paints, perfumes, pesticides and other petroleum-based products contribute to air pollution

A 2018 study by NOAA found that emissions from common household and industrial products, including perfumes, pesticides and paints, now rival motor vehicle emissions as the top source of urban air pollution.

The study, which included researchers from the University of California, Davis, found that consumer products such as shampoo, cleaning products and paint now contribute as much to urban air pollution as tailpipe emissions from vehicles.

Petroleum-based chemicals in consumer products like soaps and paints drift into the air and contribute as much as car emissions do to processes leading to air pollution. People use a lot more fuel than they do petroleum-based compounds in chemical products—about 15 times more by weight, according to the new assessment. Even so, lotions, paints and other products contribute about as much to air pollution as the transportation sector does, said lead author Brian McDonald, a CIRES scientist working in NOAA's Chemical Sciences Division.

In the case of one type of pollution—tiny particles that can damage people’s lungs—particle-forming emissions from chemical products are about twice as high as those from the transportation sector, the team found.

Consumer products cause high levels of indoor air pollution

Consumer products such as shampoo, cleaning products, perfumes, pesticides, paints, and lotions can cause high levels of indoor air pollution. A study led by NOAA and including researchers at the University of California, Davis, found that these products now contribute as much to urban air pollution as tailpipe emissions from vehicles.

This means that everyday consumer choices can have a significant impact on air quality.

The amount of VOCs emitted by consumer and industrial products is actually two to three times greater than estimated by current air pollution inventories, which also overestimate vehicular sources. For example, the Environmental Protection Agency estimates that about 75% of VOC emissions (by weight) come from vehicular sources, and about 25% from chemical products. However, the new study puts the split closer to 50-50.

Consumer and industrial products are a dominant source of urban air pollution

The study, led by NOAA and including researchers at the University of California, Davis, found that consumer products such as shampoo, cleaning products and paint now contribute as much to urban air pollution as tailpipe emissions from vehicles. This is due to the fact that these products contain compounds refined from petroleum, which drift into the air and contribute to air pollution.

The study also found that the amount of VOCs (volatile organic compounds) emitted by consumer and industrial products is actually two or three times greater than estimated by current air pollution inventories, which also overestimate vehicular sources. For example, the Environmental Protection Agency estimates that about 75% of VOC emissions (by weight) come from vehicular sources, and about 25% from chemical products. However, the new study, which includes up-to-date chemical use statistics and previously unavailable atmospheric data, puts the split closer to 50-50.

The findings highlight the impact of everyday consumer choices on air quality and suggest that reducing the use of petroleum-based compounds in chemical products could be an effective way to improve air quality in urban areas.

Vehicular emissions are overestimated as a source of air pollution

The study, led by NOAA and including researchers at the University of California, Davis, found that consumer products such as shampoo, cleaning products and paint now contribute as much to urban air pollution as tailpipe emissions from vehicles. This is due in part to the fact that the amount of VOCs emitted by consumer and industrial products is actually two or three times greater than estimated by current air pollution inventories, which also overestimate vehicular sources. For example, the Environmental Protection Agency estimates that about 75% of VOC emissions (by weight) come from vehicular sources, and about 25% from chemical products. The new study, with its detailed assessment of up-to-date chemical use statistics and previously unavailable atmospheric data, puts the split closer to 50-50.

The findings have important implications for air quality regulation and policy. They suggest that efforts to reduce air pollution should not only focus on vehicular emissions but also on emissions from consumer and industrial products. This may involve regulating the use of certain chemicals in these products or encouraging the development and use of more environmentally friendly alternatives.

In conclusion, while vehicular emissions are a significant source of air pollution, they are not the only contributor. Consumer and industrial products also play a major role, and their impact on air quality should not be underestimated. By addressing emissions from both sources, we can work towards improving air quality and protecting public health.

Consumer choices can have an impact on air quality

Consumer choices can have a significant impact on air quality.

This is surprising, as people use a lot more fuel than they do petroleum-based compounds in chemical products – about 15 times more by weight, according to the new assessment.

The impact of consumer choices on air quality is not limited to outdoor air pollution. Consumer products can also cause high levels of indoor air pollution, which can have serious health impacts, especially for those with respiratory issues. Therefore, it is important for consumers to be aware of the potential impact of their choices on air quality and to make informed decisions when purchasing and using household and industrial products.
