Not related to bloodsucking leeches, but arguably as objectionable, this term refers to the drawing out of chemicals from a material: Potentially hazardous chemicals called phthalates are thought to leach out of certain plastics, for instance, contaminating food or otherwise threatening human health. Leaching also refers to the removal of nutrients, pollutants, or other components from soil by rain, flooding, excess irrigation, or another source. It often occurs where there is a lack of proper drainage, and the process can lead to groundwater contamination and leave behind nutrient deficient soil.
