Introduction,mount of waste materials and a growing population that further aggravates the situation. This has often resulted in the transformation of lakes, rivers, and coastal waters into sewage depots where the natural biologic balance is severely upset and in some cases totally disrupted.

Metal Concentrations in River, Lake, and Ocean Waters,he oceans to the continents by wind action where is becomes deposited as rain, snow, mist or dew together with approx. 160 km. of condensate from continental sources. The most important part of this cycle occurs during transport from land to sea via ground and river waters: these 100 km. per day con
