Many common pesticides contain potent neurotoxins that can impact the nervous systems and brains not only of pests, but of humans as well. Exposures to pesticides have been linked to learning, behavioral, and developmental disabilities (Schettler et al., 2000).
Recent scientific studies also link pesticides to immune system problems (World Resources Institute, 1996) and to reproductive disorders (Tremain, 2004). Acute pesticide poisoning can also create many health problems (U.S.Environmental Protection Agency, 2004c).
In 2001, more than 1.2 billion pounds of the active ingredients in pesticides, herbicides, and fungicides were used in the United States (U.S. Environmental Protection Agency, 2004d). These chemicals were applied on land (agricultural fields, golf courses, sports fields, playgrounds,roadsides, gardens, and lawns), in homes (professional exterminations and carpet treatments, flea sprays and dips for dogs and cats),inside schools and community buildings (professional exterminations and carpet treatments, pressure-treated or CCA lumber), on bodies (head lice treatments, insect and tick repellants), and on food (during cultivation on farms as well as after
harvesting to deter fungal growth during shipping.
PBDE
Polybrominated diphenyl ethers, known as PBDEs, are synthetic, flame-retardant chemicals that are added to some fabrics and plastics during the manufacturing process.
The different kinds of PBDEs have various uses: Penta-BDEs are added to mattresses and foam cushioning in upholstery, while octaBDEs are used in business equipment,automobile trim, telephones, and kitchen appliance casings. DecaBDEs are used in electronic enclosures, such as wire insulation, televisions, and computers (Agency for Toxic Substances and Disease Registry, 2004). DecaBDEs
are also used as a fabric treatment and coating on carpets and draperies, although they are not used on clothing (Washington State Deparment of Ecology, no date).
Although we don’t have clear evidence about the health effects of PBDEs in humans, a number of harmful effects have been shown in animal studies.
• PBDE exposure before and after birth caused problems with brain development in mice. Studies have observed problems with learning, memory, and behavior (Gill, Chu, Ryan, & Feeley, 2004).
• Exposure to PBDEs during development can decrease thyroid hormone levels in mice (Gill et al., 2004). Appropriate levels of thyroid hormone is essential for healthy brain development, and decreases in thyroid hormone may contribute to problems with brain and
nervous system development (Mazdai, Dodder, Abernathy, Hites, & Bigsby, 2003).
• PBDEs also harm reproductive systems, immune system performance, and the liver in mice and rats (Gill et al., 2004; Kuriyama, Talsness, Grote, & Chahoud, 2005).
PBDEs are very similar in molecular structure to polychlorinated biphenyls (PCBs), which were banned in the 1970s because of their health effects, particularly on the neurological system. PCBs continue to persist in our environment; the primary source of exposure for children is eating high-fat foods, particularly meat and dairy, some fish, and drinking water in some areas of the U.S.
The European Union and some U.S. states are banning PBDEs as a precautionary measure and promoting materials that are natural
flame retardants.
Plastics
Some chemicals used in plastics found in everyday products have been shown to adversely impact the reproductive and neurological systems. Two chemicals of particular concern are: • Bisphenol A (BPA): BPA was invented in the 1930s and is used today as a plastic coating for children’s teeth to prevent cavities; as a coating in metal cans to prevent the metal from contact with food contents; as
the plastic in food containers; refrigerator shelving; baby bottles; water bottles; returnable containers for juice, milk, and water; micro-wave ovenware; and eating utensils (Colborn, Dumanoski, & Myers, 1996).
Other exposures result from BPA’s use in “films, sheets, and laminations; reinforced pipes; floorings; water main filters; enamels, varnish, and adhesives; artificial teeth; nail polish; compact discs; electric insulators; and as parts of automobiles, certain
machines, tools, electrical appliances, and office automation instruments” (Takahashi & Oishi, 2000).
Recent studies have linked BPA exposure to reproductive abnormalities, neurobehavioral problems, and prostrate and breast cancers. (vom Saal & Hughes, 2005)
• Phthalates: Phthalates are a class of widely used industrial compounds. About a billion pounds per year are produced worldwide. Primarily used to soften plastics, they are found in a wide range of products, including: polyvinyl chloride (PVC) flooring; newborn intensive care unit I.V. bags; children’s toys; and car seats. That “new car smell” is in part the odor of phthalates; they
become volatile when the car interior heats up. When the interior cools down, phthalates condense to form an oily film on the inside windshield.
Research now suggests that exposures to phthalates may have particularly adverse impacts on the reproductive system, including male genital malformation (associated with testicular cancer and impaired fertility), reduced sperm count, and premature breast
development in girls (Colón, Caro, Bourdony, & Rosario, 2000; Swan, et.al., 2005). Studies also link phthalates in household dust and eczema and asthma. (Bornehag, et al., 2004).
Solvents and Other Volatile Organic Compounds
Solvents are volatile liquids that are used to dissolve other materials. They are highly volatile, converting readily from liquid to gas at room temperature. Solvents occur in products we use or are exposed to everyday: alcohol, glues, paints, cleaning products, aerosols, air fresheners, moth repellents, dry cleaning fluids, varnishes, gasoline, thinners, and degreasers. Our bodies easily absorb them through direct skin contact or respiration: when inhaled, they pass quickly through mucous membranes and lungs
into the bloodstream (U.S. Environmental Protection Agency, 2004a).
Many health risks are associated with solvent exposure: throat and lung irritation upon inhalation; dizziness; unconsciousness; and in some very rare cases, death. Solvents have also been linked to various cancers and neurological problems. Exposure in the womb may result in birth defects and sometimes miscarriage (U.S. Environmental Protection Agency, 2004a).
Specific solvents include: • Alcohol: rubbing alcohol (a disinfectant); beer, wine, and cocktails. • Toluene: in spray paints, glues, nail polish, carpet spot removers, varnish, and lacquers. • Butane: in cigarette lighters and in fuel. • Benzene: in gasoline and in cigarette smoke. • Perchloroethylene: in dry cleaning.
