Document Summary
Directly south of the city of sarnia; made up of huge chemical corporations; st. claire river; solvent producers; benzene exposure, formaldehyde, etc. Birth ratio of boys to girls had changed; twice as many girls being born as boys; endocrine disruption. Chemicals act as if they were hormones (disruptors); development of the fetus is under the control of hormones; chemicals into the birthing environment will disrupt the developmental process (and differentiation of sexes) These chemicals released into environment causing abnormalities and deformities within animals/wildlife. Hormonal disruption in the life cycle; if fetus is development, profound effect on health of person as a child, or in adult life, etc. Puppy drank from the river when pregnant: 3 puppies died right at birth due to breathing problems; major developmental problems of the fetus; miss-grown limbs/appendages, etc. Sediment of st. claire river contained chemicals (solvents); main contaminant = mercury; mixed sediment with hay/manure to create soil and release chemicals as.
