Consumer Goods: Unseen Pollution Sources In Our Homes

Many consumer products contribute to air pollution, especially in urban areas. Volatile organic compounds (VOCs), a class of widely used chemicals, are a significant source of pollution. These compounds are found in personal care products, paints, cleaners, perfumes, and other scented items. While people use far more fuel than petroleum-based compounds, the emissions from these consumer products are substantial and can have harmful effects on human health.

Characteristics and Values of Consumer Products that Cause Pollution

Volatile chemical products like perfumes, paints, and scented items

Volatile chemical products like perfumes, paints, and other scented items are a significant source of pollution, according to a surprising NOAA-led study. The study, published in the journal Science, found that emissions from these products can rival those of vehicles in greater Los Angeles. Despite 15 times more petroleum being consumed as fuel than used in industrial and consumer products, the amount of chemical vapors emitted by scented items is comparable. These chemical vapors, known as volatile organic compounds (VOCs), react with sunlight and other chemicals in the atmosphere to form ozone pollution and fine particulates in the air.

The issue with scented products is that they are designed to evaporate and spread their aroma, whereas fuel systems are designed to minimize evaporation and maximize energy generated by combustion. This fundamental difference leads to a disproportionate air-quality impact of chemical products compared to fuels. Each spritz of perfume releases VOCs into the environment, which can have harmful effects on both the environment and human health.

The Environmental Protection Agency has identified potential links between VOC exposure and kidney, liver, and nervous system damage, as well as possible cancer risks. These compounds can also cause minor side effects such as irritation and headaches. While the focus of air quality programs has traditionally been on transportation-related pollution, the NOAA study highlights the need to consider the impact of volatile chemical products as well.

It is worth noting that the beauty industry is vast, and some brands are making efforts to reduce their environmental impact. However, the daily use of products like perfumes, hair sprays, and air fresheners can contribute to air pollution. This information is particularly relevant for consumers who are environmentally conscious and concerned about the impact of their personal care choices.

VOCs in consumer goods

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs are emitted by a wide array of consumer goods, including paints, varnishes, wax, cleaning products, disinfectants, cosmetics, degreasers, and hobby products. Fuels are also made up of organic chemicals. These products can release organic compounds while they are being used and, to a lesser extent, when they are stored.

A surprising NOAA-led study found that emissions from volatile chemical products like perfumes, paints, and other scented items now rival vehicle emissions as a source of pollution in greater Los Angeles. Another study published in Science found that petroleum-based chemicals used in personal care products, paints, and cleaners contribute as much to volatile organic air pollution in urban areas as cars and trucks.

VOCs have been shown to cause cancer in animals in laboratory studies, and some are suspected or known to cause cancer in humans. Common symptoms of exposure to high levels of VOCs include irritation and illness, particularly in people with respiratory problems such as asthma, young children, the elderly, and people with heightened sensitivity to chemicals.

To reduce exposure to VOCs, it is recommended to limit the number of products in the home that give off VOCs, properly store or dispose of unused chemicals, increase ventilation by opening doors and windows, and use fans to maximize outdoor air circulation.

Petroleum-based compounds in personal care products

The use of petroleum-based compounds in personal care products has emerged as a significant source of pollution, particularly in urban areas. These products, including shampoos, conditioners, anti-aging creams, body lotions, perfumes, lipsticks, and sunscreens, contribute to volatile organic air pollution. The issue is exacerbated in indoor environments, where the majority of these products are used, and the emissions are not effectively regulated or ventilated.

Petroleum, also known as petrochemicals, is a prevalent ingredient in personal care products due to its emollient and occlusive properties. It helps soothe and smooth the skin, creating a waterproof barrier that seals in moisture. However, the presence of petroleum in these products poses several health and environmental risks. One of the primary concerns is the generation of 1,4-dioxane, a toxic substance known to potentially contribute to cancers and disrupt the endocrine system. According to the Environmental Working Group (EWG), an alarming 22% of conventional personal care products contain unsafe levels of 1,4-dioxane, which can readily penetrate the skin.

The use of petroleum-based products has also been linked to skin breakouts, including pimples, whiteheads, and blackheads. Incomplete refining processes can contaminate petroleum jelly with Polycyclic Aromatic Hydrocarbons (PAH), which are considered potential carcinogens by the National Toxicology Program (NTP). Additionally, the volatile chemical emissions from these products contribute to air pollution, rivaling vehicle emissions in some urban areas like Los Angeles, according to a NOAA-led study.

To address these concerns, some companies have started to offer alternative beauty and personal care products that are free from petroleum-based ingredients. These companies prioritize creating natural, organic, and non-toxic formulas that are safe for both consumers and the environment. For example, Love Sun Body offers sunscreens that are 100% natural, safe for marine life, and free of chemical filters and petroleum-based ingredients. They have obtained certifications, such as the COSMOS-standard signature, to assure consumers of the natural origin and safety of their products.

While the adoption of alternative, non-petroleum-based products is a positive step towards reducing pollution and health risks, it also underscores the need for stricter regulation and labeling requirements in the beauty and personal care industry. Currently, the industry is largely unregulated, allowing many hidden toxins to be present in products. More comprehensive safety standards and transparency in ingredient listings are necessary to protect consumers and the environment from the potential harms associated with petroleum-based compounds in personal care products.

Household products like cleansers and disinfectants

Household cleaning products, such as cleansers and disinfectants, can have a significant impact on both indoor and outdoor air pollution. Volatile Organic Compounds (VOCs) are a class of pollutants commonly found in household cleaners, including soaps, shampoos, deodorants, air fresheners, glues, and cleaning sprays. These compounds evaporate easily and can linger in the air, contributing to smog and poor indoor air quality. VOCs have been linked to adverse health effects, including respiratory issues and an increased risk of developing asthma. In some areas, legislation has been enacted to restrict or ban VOCs in household cleaners due to the severity of the pollution they cause.

Additionally, certain chemicals in household cleaning products can be dangerous when mixed. For example, mixing bleach with ammonia or other acidic substances can create chloramine vapors, which are irritating to the respiratory system, eyes, and skin, and may lead to long-term respiratory issues. Similarly, combining bleach with rubbing alcohol can produce chloroform and other by-products that can cause dizziness and nausea when inhaled. The use of multiple cleaning products in quick succession, even without intentional mixing, may also inadvertently trigger harmful chemical reactions.

Some common household cleaning chemicals, such as nitrogen, phosphorus, and ammonia, are not effectively removed by waste treatment processes and end up in waterways. These chemicals act as fertilizers, causing excessive growth of certain types of plant life in aquatic habitats, disrupting the native ecosystem.

The impact of household cleansers and disinfectants on pollution has led to a rise in demand for "natural" and "green" cleaning products that do not contain synthetic chemicals. While research on their effectiveness and impact on respiratory health is ongoing, initial studies suggest that these products, which contain only biodegradable ingredients, may be less harmful to the environment and indoor air quality.

Ozone-friendly chemicals

CFCs, a common ODS, are gases used for refrigeration, air conditioning, packaging, insulation, solvents, and aerosol propellants. They are not destroyed in the lower atmosphere and can, therefore, drift into the upper atmosphere, where they break down ozone. This process releases chlorine or bromine atoms, which deplete the ozone layer.

The good news is that there are now alternatives to these harmful chemicals. Hydrochlorofluorocarbons (HCFCs), for example, are interim replacements for CFCs. While they are still ozone-depleting substances, they are less potent than CFCs. Another option is hydrofluorocarbons (HFCs), which have a global warming potential but do not deplete the ozone layer as they do not contain chlorine.

It is important to note that while these new compounds are better for the ozone layer, they are still greenhouse gases and contribute to global warming. The atmospheric lifetime and global warming potential of these compounds vary, with some having a more significant impact on the environment than others.

Overall, the adoption of ozone-friendly chemicals is a positive step towards protecting the environment and the ozone layer. While there are still challenges, such as the global warming potential of some compounds, the development and use of these alternatives demonstrate a commitment to reducing the negative impact of human activities on the planet.
