Environmental ContaminantsEnvironmental Contaminants
-Found in air, water & soil
-Definition: any natural or man-made compound that is harmful to human development & health.
-Environmental Contaminates that affect the central nervous system during prenatal development are called neurotoxicants.
NeurotoxicantsNeurotoxicants
Cause neurological dysfunction to child during pre& post natal development.
Timing & Dosage matter, but hard to measure.

MERCURYMERCURY
Exposure through: fish, vaccines & dental amalgams.
-Methylmercury(found in fish)-affects brain during pre-natal development
-Thimerosal (found in vaccines) -Thought to be linked with Autism.
-Dental Amalgams- Mercury enters blood stream through dental fillings.

LEADLEAD
Exposure through: pipes, paint, gasoline, pottery, and industrial emissions.
Correlation between lead levels and low IQ scores in urban children.

PCB/DIOXINSPCB/DIOXINS PCB= Polychlorinated Biphenyls
chemical found in many industrial applications
Dioxins-by product of industrial applications.
Non-biodegradable, so in environment indefinitely.
More common in males.

PESTICIDESPESTICIDES Used to protect plants & crops from
contamination and destruction from insects & microorganisms.
US replaced using DDT with Organophosphates (OP), but still not 100% safe.

ALCOHOLALCOHOL
2 Types: Ethanol (beverages) & Methanol (Wood)
Through ethanol use, child likely to develop fetal alcohol syndrome
Methanol research too new

TABACCO SMOKETABACCO SMOKE
Exposure 2 ways: Maternal use & passive post-natal exposure.
Hard to separate chemicals
Passive post-natal more dangerous

What & WhyWhat & Why
What can we do? EDUCATE!
Why should we care? Teaches us more about our students and how
the environment we live in effects them
