How does geology influence the distribution of toxic substances?
Geology plays a crucial role in the distribution of toxic substances. The lithosphere, which is composed of rocks and soil, can naturally contain toxic elements such as arsenic, lead, and mercury. The geological processes such as weathering, erosion, and volcanic activity can mobilize these elements, affecting their concentration in the environment. For instance, arsenic contamination in groundwater is often linked to natural geological formations, where minerals containing arsenic dissolve into the water supply.
