Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
This chapter deals with aspects concerning the presence of sulfur, aluminum, arsenic, cadmium, lead, mercury, and nickel in marine environments. For each of these elements, information about their natural and anthropic sources, as well as their toxicity and accumulation in different organisms, was provided. It was shown that the total accumulation of aluminum, cadmium, lead, mercury, and nickel in physical marine compartments (water, particulate matter, and sediments) is not necessarily related to the bioaccumulation of these elements, since many aspects concerning the bioavailability (including chemical speciation) should be considered.
