CHMM EXAM WITH 100% CORRECT ANSWERS Bioaccumulation - correct answerImplies the accumulation of a toxic chemical in tissue, like DDT and PCBs that are stored in fatty tissues or mercury building up in fish Biomagnification - correct answerthe increase of of the chemicals in the natural food chain as contaminated food species are eaten, like fish consumers that have high bloodstream from seafood sources Bioconcentration - correct answerused in the field of aquatic toxicology and is t...

What are Organochlorines (OCs) - >>synthetic lipophilic products that resist degradation T or F: OCs have low mammalian toxicity - >>true Where are you most likely to find OCs? - >>higher order organisms (more fat), polar caps, sediment What is the Bioconcentration Factor (BCF)? - >>the heavy metal concentration present in biomass compared with the environment What is the BCF of DDT in rainbow trout? - >>50,000 ppm Most of the OCs in 99% of Americans are larg...

Swamps - Contain woody plants, macrophytes can grow in the open, does not accumulate a lot of peat; has an external water supply Bogs - Accumulate peat and primary vegetation in acidophilic mosses and sedges; Trees and macrophytes are rare; no external water supply-- reliant on rain water; ombrotrophic Ombrotrophic - Minerals enter through rainwater. Fens - Share characteristics of bogs and marshes; distinguished by mineral-rich groundwater inputs that cause a higher ph than bogs; m...
