Source of the pollutant

Emissions of cadmium (Cd) of human origin are mainly released by zinc production and waste incineration. The combustion of solid mineral fuels, heavy fuel oil and biomass also releases a significant proportion of Cd emissions.

Cadmium naturally present in the Earth's crust can be dispersed into the air in particulate matter from the soil and by volcanic eruptions. These activities are not covered by CITEPA at present, because of insufficient data on potential emissions and a lack of bibliographic references.

 

Effect of the pollutant

In humans, Cd is mainly absorbed by inhalation and ingestion. It is transported in the bloodstream and concentrates mainly in the liver, kidneys and bones. Acute cadmium poisoning first affects the digestive system. When inhaled, severe cadmium poisoning causes pneumonia. Chronic exposure can lead to kidney failure. The International Agency for Research on Cancer (IARC) has classified cadmium as carcinogenic to humans.

Heavy metals can be toxic for the biosphere. Most being under particulate shape, they accumulate in the water, the grounds, the food and the air.
