The Effects Of Lead On The Environment
According to NCBI, lead is one of five heavy metals that are considered toxic to humans and the environment. Mining, smelting, manufacturing, recycling activities and its widespread use in some products have led to contamination of the environment and exposure to humans causing harm to our health. Homes built before 1978, which most likely used

Importantly, they are also frequently a source of long-term environmental risk due to acid drainage, leaching, and water or wind-borne redistribution. Weathering and biogeochemical activity in the mine wastes may result in critical minerals becoming easier or harder to recover and may also affect the potential for additional environmental impacts.
