Effect of Pesticide Pollution on Environment and Human Health

Less than 0.1% pesticides applied for pest control reach to their target pest Thus, more than 99.9% pesticides used to move into environment where they adversely affect public health and beneficial biota, and contaminated soil water and the atmosphere of the ecosystem. In this study we concern about the environment impact of repeated pesticide use has prompted research into the environmental fate of these agents which can emigrated field to air, other land water bodies. How long the pesticidal remain in the soil depends an how strangely it is bound by soil components and how readily it is degraded. It also depends upon the environmental condition at the time of application e.g. Soil water content pesticides use must ensure public safety and environment protection with both the chemical itself and their potentially harmful metabolites. This paper reviews what is known of the influence of the physical and chemical characteristic of the soil system, such as moisture content organic and absorption of and degradation of pesticides and their access to groundwater and surface water. Thus new tools or technique with greater reliability than those already existing are needed to predict the potential hazardous effect of pesticides and thus contribute to reduction the adverse effect on human health and the environment
