Cadmium Toxicity: Where is Cadmium Found? | Environmental ...

The most important sources of airborne cadmium are smelters. Other sources of airborne cadmium include burning fossil fuels such as coal or oil and incineration of municipal waste such as plastics and nickel-cadmium batteries (which can be deposited as solid waste) (Sahmoun et al. 2005).Cadmium may also escape into the air from iron and steel production facilities.

Zinc Nickel – The Cadmium Replacement | Knowledge Hub | …

Zinc nickel coatings work in almost an identical way to cadmium in that it provides a sacial coating to protect against corrosion and is applied via electroplating. Zinc is the sacial element within the coating, but on its own it is too active and corrodes too easily. This is why between 12 and 16% nickel is added in order to slow the ...
