Cadmium in the atmosphererise to emissions one order of magnitude greater than natural sources, are largely primary non-ferrous metals production and waste incineration. Measured concentrations of airborne cadmium are typically < 1 ng m. at remote sites, 0.1–10 ng m. at rural sites and 1–100 ng m. at urban and industrial si

The distribution of cadmium in the seanditions. Among the heavy metal trace-elements with general or potential ecotoxic significance (Pb, Hg, Cu, Ni, Cr, As, Zn), Cd occurs in surface waters of the open oceans in the relatively lowest concentrations, mostly between 0.1 and 20 ng/kg. The lower section of this range corresponds to large a

Removal of cadmium from wastewaterses in various industrialized nations to impose severe discharge limits for certain heavy metals. This paper describes the source and quantity of cadmium in waste waters. The effluent limitation of cadmium is presented, followed by discussions of various treatment methods including chemical precipita

Bioaccumulation of cadmium in marine organismss et al.. suggested the background concentration of Cd for North Atlantic surface waters to be 40–60 ng/1. The level for Pacific oceanic water is 36 ng/1.. Increased concentrations have been observed in the Mediterranean, Baltic, and North Sea, where circulation and water mass turnover are limited.

Cadmium in freshwater ecosystemss. It is evident that a toxic substance may influence the biota if its concentration in the environment is over a certain level. Indeed, some heavy metals, dangerous at high concentrations, are essential to the biota at low concentrations. Unfortunately, it is often difficult to establish this level
