Alkylphenols are a large family of organic compounds used in a wide variety of products, including cleaning products, beauty products, contraceptives, coatings, fragrances, thermoplastics, carbonless copy paper, and agrochemicals. Most concerns are focused on alkylphenol ethoxylates (APEs), which bioaccumulate and have been shown to cause endocrine disruption in fish. They are in cleaning products that end up in waterways from wastewater treatment effluent. Some alkylphenols, especially nonylphenol, are being phased out in Europe and more research into their impacts is needed. A few governments with environmentally preferable purchasing programs restrict or ban APEs.

Antimicrobials are a class of chemicals used in many personal care and consumer products to kill or inhibit the growth of microbes. Antimicrobials of concern include halogenated aromatic compounds such as triclosan and triclocarban, nanosilver, and quaternary ammonium compounds (quats) such as benzalkonium chloride. These chemicals have biocidal properties when evaluated under lab conditions. However, there is little evidence supporting the benefits of antimicrobials in consumer products. Furthermore, common antimicrobials are toxic to aquatic life and are associated with adverse health impacts.

Bisphenol A (BPA) is used to manufacture polycarbonate (clear, hard) plastics and epoxy resins. The plastics are used in many consumer products, such as drink bottles, DVDs, eyeglass lenses, electronics, car parts, and other products that must not break easily. Epoxy resins are used for lining food cans and water pipes, and for many sales receipts. Most recent testing has shown the largest health-related concern to be potential impacts on the brains, behavior, and prostate glands of fetuses, infants, and small children so most health organizations advise against the use of BPA for baby bottles and related products. BPA has also been found in breast milk.

Bisphenols are industrial chemicals that have been used to make polycarbonate plastics and epoxy resins since the 1960s. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. Epoxy resins are used to coat the inside of metal products, such as food cans, bottle tops and water supply lines. Some research has shown that bisphenols can seep into food or beverages from containers that are made with them. Exposure to bisphenols is a concern because of possible health effects to the brain, behavior and prostate gland of fetuses, infants and children.

The US Department of Health and Human Services and the International Agency for Research on Cancer have determined that cadmium is a known human carcinogen, associated with lung cancer. Additionally, acute and long-term exposures can lead to lung and kidney damage, bone loss, hypertension. In sufficient quantities, cadmium is lethal. Cadmium’s extreme toxicity means that overexposure can occur even when only trace amounts are present, such as during smelting and electroplating activities.

Chlorinated Polyethylene (CPE) and Chlorosulfonated Polyethylene (CSPE) are Persistent Organic Pollutant Source Materials: due to their carbon-chlorine bases, these products contribute to the creation of dioxins and furans at different points in their life cycle (often manufacturing and/or disposal). According to the World Health Organization, dioxins are some of the most potent toxins known to humans, with no known safe limit for exposure and a strong propensity for bioaccumulation. In addition, dioxins are highly persistent in the environment. Similarly, furans accumulate in animal fat, concentrating as they travel up the food chain. Non-chlorinated polyethylene products are readily available in many product categories.

Chlorobenzene is used primarily as a solvent, a degreaser for auto parts, and a chemical intermediary for making other chemicals, so exposures is primarily a risk to workers making or using it. Most exposures are through inhalation of fumes. Shortterm exposure can cause headaches, sleepiness, nausea, numbness, muscle spasms, and in extreme cases, unconsciousness. Chronic (long-term) exposure can cause increased signs of neurotoxicity (numbness, etc.) and irritation of the upper respiratory tract. In animals, chronic exposure has also caused kidney and liver damage. Chlorobenzene is broken down by sun and bacteria in the environment and does not accumulate in the food chain.

Although chromium is a naturally occurring element and chromium III (trivalent chrome) is an essential nutrient, chromium VI (hexavalent chrome) can cause serious health issues, especially for factory workers who can inhale or ingest it during manufacturing. There has been concern about it in drinking water and, lacking EPA maximum allowable levels, the State of California set a public health goal for it. Chromium VI is used primarily for chrome plating of metals for decorative or protective finishes, making stainless steel, leather tanning, anti-corrosive agents for paints, and in textile dyes and pigments. Long-term or high-level exposure through inhalation can cause nasal irritation and ulcers, breathing problems, and nasal and lung cancer in unprotected workers. Ingestion can cause anemia and/or stomach tumors. Skin contact can cause skin ulcers and allergic reactions.

Pre-consumer recycled content (synthetic gypsum) is created from environmental control systems installed in the smokestacks of coal-fired power plants. These systems capture particles from coal burning as they travel through the smokestack or flue. This becomes Flue-Gas Desulfurization (FGD) gypsum. FGD in drywall results in the global distribution of mercury, a potent developmental and neurotoxic metal that persists in the environment, accumulates in the food chain, and is highly toxic. The very pollution that is being captured in the flue of the power plant is being released from the smokestacks of wallboard factories that use FGD residuals.

VOCs are members of a large group of organic chemicals that can evaporate into the indoor air under normal temperature conditions and into the outdoor air, causing environmental impacts such as photochemical smog. Their health effects vary widely, from respiratory irritants to human carcinogens (such as formaldehyde), which is a concern since they are ingredients in many products in the built environment. On-site wet applied products (paints, adhesives, and sealants) are of particular concern because they can directly impact the health of installers who may not be using breathing or dermal protection, unlike in-factory wet applied materials that are (usually) applied with worker and environmental protections in place.
