Document Summary
Utilizing plants to clean up chemicals (e. g. cottonwoods, poplar, juniper trees, grasses, alfalfa) Sun ower plants e ectively removed radioactive cesium and strontium from ponds at the. A waste treatment soil clean-up process that involves spreading contaminated soils on a pad and and periodically turning it over (tilting) to aerate the mixture so that water and leachates can leak out of the soil. Accumulation of substances, such as pesticides, or other chemicals (heavy metals) in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost by catabolism and excretion. In bioaccumulation, organisms higher up on the food chain contain higher concentrations of chemicals than organisms lower on the food chain. #e. coli can be engineered to clean up heavy metals (e. g mercury and methyl-mercury). Using living organisms to detect and assess harmful levels of toxic chemicals.
