200-year record of metals in lake sediments and natural background concentrations

Article Abstract:

The investigation of metals present in Lake Zurich, Switzerland, covering a time span of 200 years before the present time, reveals that the concentrations of the elements differed less with pre-anthropogenic sediments and represent geochemical background representation. The concentration of copper, zinc and cadmium have steadily increased until about 1960 when stricter environmental laws, public awareness toward environmental protection and the introduction of sewage treatment plants brought a considerable improvement in their concentration levels.

A 200 year record of atmospheric cobalt, chromium, molybdenum, and antimony in high altitude alpine firn and ice

Article Abstract:

Research in the French and Italian Alps indicates that concentrations of four heavy metals in the snow are, on average, significantly higher than concentrations dated before 1850.
