Document Summary
Case study: environmental toxins and our health: environmental toxins. Dramatic increase in production of chemical substances (>80k registered for use). 3-4k identi ed as high-volume chemicals (>1 million pounds/year). Through sources like food, the outdoor environment, the workplace, home/indoor, and personal care products. The body burden of newborns is increasing, exposed to hundreds of environmental toxins before they are even born: exposure. Some of us are at greater risk than others. Individuals have different exposures and different risks, meaning differing vulnerabilities. Both high- and low-level exposure have different health implications: harm from environmental toxins. Particular risk during prenatal and early childhood period. Low birthweight, premature delivery - pbdes, pesticides, toluene. Decreased cognitive function - lead, mercury, pesticides, pcbs. Behavioural disorders - bpa, pbde, lead, pesticides, phthalates. Certain cancers - benzene, bpa, pops, parabens, phthalates. Poor respiratory health - smoking/ets, outdoor air pollution, vocs: strategies.
