Mining - Wikipedia

Mine waste-materials rejects or traces due to mining activity can be found in the vicinity of the mine, sometimes far away from the source. Established plants cannot move away from perturbations, and will eventually die if their habitat is contaminated by heavy metals or metalloids at a concentration that is too elevated for their physiology.
