Simply edited: …is the study of the effects of toxic chemicals on biological organisms
Perhaps you have read stories about the rise of hermaphroditic frogs & fish? Well, it may be our own fault~ the pharmaceuticals we ingest nationally and those we inject into our livestock, (etc.) are not broken down completely when disposed of (usually in waste water)…. and though some do not disrupt systems of organisms individually, the cocktail of chemicals together creates disaster. The good thing is, this has lead to the increased demand for “green pharmacy” (drugs that can breakdown safely in nature).
What do you think about Ecotoxicology?
