Down the Drain
List of Dangerous Chemicals used in the home:
Irritation to eyes and mucous membranes. Breathing difficulty, wheezing, chest pains, pulmonary edema, skin burns. High exposure can lead to blindness, lung damage, heart attack or death.
2-butoxyethanol/ Ethylene glycol butyl ether
One of many glycol ethers used as a solvent in carpet cleaners and specialty cleaners. Can be inhaled or absorbed through the skin and may cause blood disorders, as well as liver and kidney damage. May also cause reproductive damage with long-term exposure 1,4 dichlorobenzene (1,4 DCB) Has been linked to a reduction in pulmonary function. Found in space deodorizing products, such as room fresheners, urinal cakes, toilet bowl fresheners and cleaning products it is also used as an insecticide for moth control.
Ethoxylated nonyl phenols (NPEs)
Known as “gender-benders,” nonyl phenols can induce female characteristics in male fish, for example. The threat posed to the environment by nonyl phenols prompted the European Union to ban them from all cleaning products manufactured or used in the EU. Still used in the U.S.
Methylene chloride is listed as a possible human carcinogen by the International Agency for Research on Cancer and is commonly found in paint strippers. In 1987, regulators in the U.S. compelled manufacturers to put warning labels on products containing methylene chloride.
Either naphthalene, or another chemical called paradichlorobenzene, is used in mothballs and moth crystals. Naphthalene is listed by California’s Office of Environmental Health Hazards Assessment as a substance “know to the state to cause cancer,” while paradichlorobenzene is listed by IARC as a possible human carcinogen. Avoid all moth products that contain either of these two ingredients.
Made from finely ground quartz, silica is carcinogenic as a fine respirable dust. Silica is found in that form in some abrasive cleansers, which are often used on a regular basis around the home.
Toluene is a potent reproductive toxin, which is used as a solvent in numerous products, including paints. It is also sold as the pure product and is listed by California’s Office of Environmental Health Hazard Assessment as a reproductive toxin that may cause harm to the developing fetus. Pregnant women should avoid products containing toluene.
Trisodium nitrilotriacetate (NTA)
NTA is listed as a possible human carcinogen by the International Agency for Research on Cancer. It is used as a builder in laundry detergents and also has an adverse environmental impact as it can impede the elimination of metals in wastewater treatment plants. NTA’s action can cause metals that have already settled out to be re-mobilized back into the liquid waste stream.
Another extremely toxic ingredient that is often found in graffiti and scuff removers, spray paints and some adhesives. A suspected reproductive toxin that has shown reproductive harm in laboratory experiments, it is also a neurotoxicant that can cause memory loss on repeated exposure.
Formaldehyde is also used as a preservative in cosmetics, shampoos, antiperspirants, nail-hardening solutions, veterinary treatments and as a soil steriliser.
paradichlorobenzene (PDB) - Fragrance in air fresheners -- liver and nerve damage
paradichlorobenzene - Toilet cleaners -- should be avoided as this chemical has been linked to liver and nerve damage.Triclosan - Antibacterial -- may increase the likelihood of auto-immune conditions like asthma and other allergic responses
Bleach (Sodium hypochlorite)
When bleach is mixed with acids (typically found in toilet bowl cleaners), it reacts with them to form chlorine gas. When it is mixed with ammonia, it can create chloramine gas, another toxic substance.
In the environment, sodium hypochlorite is acutely toxic to fish. The chlorine in bleach can also bind with organic material in the marine environment to form organochlorines, toxic compounds that can persist in the environment. There may be some circumstances where bleach use is necessary for disease control, but there is little need for it on a regular basis. Tests have shown that washing counters and other surfaces with soap and water removes most bacteria and there are a number of oxygen-based alternatives for laundry uses of bleach.
Manufacturers have since reduced or even eliminated phosphates from laundry products, but no action has ever been taken on dishwasher detergents. Most of the products available from major manufacturers contain 30-40 per cent phosphates. Some also contain high levels of chlorine-based sanitizing ingredients.
FD & C Blue Dyes 1 & 2 can trigger a wide number of behavioral, learning, and health problems. FD&C color dyes may also cause potentially severe allergic reactions, asthma attacks, headaches, nausea, fatigue, nervousness, lack of concentration, and cancer. (From “Formation of carcinogenic aromatic amine from an azo dye by human skin bacteria in vitro” & “Skin discoloration with blue food coloring”)
Sodium Lauryl Sulfate (SLS) and its close relative Sodium Laureth Sulfate (SLES) are commonly used in many soaps, shampoos, detergents, toothpastes and other products that we expect to "foam up". Both chemicals are very effective foaming agents, chemically known as surfactants. Both SLS and SLES are known to have many effects that can potentially be detrimental to health. Among the possible dangers are the following
- Skin irritation / skin corrosion
- Hormone Imbalance
- Eye irritation / eye deformities in children
- Protein Denaturing
- Carcenogenicity (potential to cause cancer)
NPE The detergent is called nonylphenol ethoxylate (NPE), and the endocrine disruptor is nonylphenol (NP). Generally, the detergents themselves are not thought to be endocrine disruptors, although there usually is a small amount of NP in the product as a contaminant. The main concern with these ingredients is not for human health but rather for aquatic life. Male fish have been shown to become feminized when exposed to NP, as well as when exposed to sewage effluent, which also contains other more potent endocrine disrupting substances. NP acts like the hormone estrogen, causing male fish to produce a protein needed for egg production and normally only found in female fish. If exposure is high enough, it can interfere with reproduction.
