cadmium has become a vital component of modern technology, with countless applications in the electronics, communications, power generation and aerospace industries 4,5. In the European Union and worldwide, approximately 8590 of total airborne cadmium emissions arise from anthropogenic sources, mainly from smelting and refining of nonferrous

EXPOSURE TO CADMIUM A MAJOR PUBLIC HEALTH

Exposure To Cadmium A Major Public Health

Cadmium releases can be carried to and deposited on areas remote from the sources of emission by means of long-range atmospheric transport. 6. Industrial processes. Commercial cadmium production started only at the beginning of the 20th century. Initially, its main use was in electroplating, but since 1960, cadmium has been used for manufacturing

Status assessment of toxic chemicals cadmium

Status Assessment Of Toxic Chemicals Cadmium

Major sources of cadmium emissions are nonferrous metal refining and coal combustion which respec- tively contribute 952 metric tonsyr and 235 metric tonsyr of cadmium to the atmosphere. Cadmium contamination in water is primarily from the electroplating industry which releases 160 met- ric tonsyr. Waste cadmium is deposited on land areas by ...

Life cycle impact analysis of cadmium in CdTe PV

Life Cycle Impact Analysis Of Cadmium In Cdte Pv

This paper describes the material flows and emissions in all the life stages of CdTe PV modules, from extracting refining and purifying raw materials through the production, use, and disposal or recycling of the modules. The prime focus is on cadmium flows and cadmium emissions into the environment.

Cadmium 1 What is Cadmium

Cadmium 1 What Is Cadmium

Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper production. It is therefore primarily produced in relation to zinc production rather than direct cadmium demand. Global cadmium production almost doubled between 1950
