Impact of Heavy Metals in Natural Waters,, and species composition of populations. The nature and extent of change depends largely on the concentration of heavy metal species in the water and sediment. Hence, physicochemical processes within effluents and natural waters have a major, albeit indirect, effect on biological responses.

Introduction, disruptions. For example, the contamination of fish in the lower Great Lakes with mercury and PCB’s came as a surprise to many people, including regulatory agencies which eventually pressed for compensation for local fisherman.

Arsenic,ny enzyme system. However, arsenate inhibits ATP synthesis by uncoupling oxidative phosphorylation and replacing the stable phosphoryl group, whereas arsenite inhibits thiol-dependent enzymes, retained in the body tissue proteins, such as keratin disulfides in hair, nails and skin.
