Dispose of excess pesticides by applying them to labeled sites. The K oc describes the relative affinity or attraction of the pesticide to soil material and, therefore, its mobility in soil. Pesticides with small K oc values are more likely to leach than those with high K oc values. The storage or accumulation of materials in the tissues of living organisms. A property that makes a material more likely to cause cancer in humans or animals that are exposed to that property.
Degradation occurs due to sunlight, soil microorganisms, and chemical reactions in the soil.
Soil temperature and moisture can greatly affect degradation. Degradation rate is quantified in terms of degradation half-life, the time required for 50 percent of the pesticide to decompose to products other than the original pesticide. The EPA considers a pesticide with soil half-life of greater than 21 days as having a potential for causing water concerns due to the pesticide s longevity. A region within the earth that is wholly saturated with water. Dissolving and transporting of materials by the action of percolating water.
