    easily discarded in the environment, in contrast to mercury products such as batteries. Secondly, the use of methylmercury means that subsequent pollution of the environment with the drug will not lead to bioaccumulation, (the presence of large amounts of pollutants in top consumers of the food chain) in ecosystems. This is because, unlike other types of mercury compounds like methylmercury, ethylmercury can clear through the bloodstream extremely quickly, meaning that pollution of the environment

    Assignment 5 - Neurotoxicity 1. Describe the differences in the physical properties of organic, inorganic and elemental mercury (6 marks) Elemental mercury is also known as metallic mercury. It is shiny and silver-white in colour. At room temperature, elemental mercury is in a liquid state and some of this liquid mercury will evaporate and form mercury vapor. The vapor itself is colourless and odorless. Inorganic mercury consists of salt compounds with elements such as chlorine, sulfur, and oxygen

    mercury enters a complex cycle in which one form can be converted to another. Mercury attached to particles can settle onto the sediments where it can diffuse into the water column, be resuspended, be buried by other sediments, or be methylated. Methylmercury can enter the food chain, or it can be released back to the atmosphere by volatilization. The concentration of dissolved organic carbon (DOC) and pH have a strong effect on the ultimate fate of mercury in an ecosystem. Studies have shown that for
