Fluxes and Sources of Heavy Metal Inputs into the Southern Bight of the North Sea
Chemicals, both natural and man-made, reach the North Sea through a number of different routes. For many years, research on pollution of the marine environment has focused on the most obvious inputs: those borne by rivers and direct discharges of waste. However, a number of studies conducted at the end of the 1970’s and at the beginning of the 1980’s revealed that a substantial fraction of the contamination entering the ocean, the North Sea and Baltic Sea, derives from sources located on land via atmospheric input. Gradually more importance has been given to the atmospheric route relative to the other pathways. The aim of this study was to estimate from field measurements the atmospheric input of some heavy metals into the Southern Bight of the North Sea, namely between the Dutch and English coast, for comparison with the input by other pathways, and to serve as a calibration reference for model calculations.
