Cadmiumverluste

Cadmiumverluste, or cadmium losses, refer to the unintended release of cadmium—a heavy metal and environmental pollutant—into the environment through various industrial, agricultural, and natural processes. Cadmium is primarily emitted as a byproduct of mining and smelting activities, particularly in the extraction of zinc, lead, and copper. It can also enter the environment through the combustion of fossil fuels, waste incineration, and the use of phosphate fertilizers in agriculture.

The primary sources of cadmium losses include industrial emissions, where it is released into the air as fine particles or dissolved in wastewater. Once released, cadmium can persist in the environment for extended periods due to its low volatility and high solubility in water. It accumulates in soil and sediments, where it poses risks to plants and microorganisms. Over time, cadmium can also leach into groundwater or be taken up by crops, entering the food chain and posing health risks to humans and animals.

Mitigation of cadmium losses involves implementing stricter industrial regulations, such as emission controls and wastewater treatment systems, to reduce direct releases. In agriculture, the use of low-cadmium fertilizers and soil amendments can help minimize uptake by plants. Additionally, proper disposal and recycling of cadmium-containing materials, such as batteries and electronic waste, can prevent further environmental contamination. Public awareness and sustainable industrial practices are also crucial in reducing cadmium’s impact on ecosystems and human health.
