Water Pollution and Agriculture Pesticide

The agricultural industry uses substantial amounts of water (the highest in the world) mostly for irrigation purposes. Rapid population growth and, consequently, growing demand food have increased use pesticide to higher yield crops and other products. Wastewater generated as a result excessive pesticides/herbicides is becoming global issue specifically developing countries. Over 4,000,000 tons pesticides are currently used world annually high concentrations above their threshold limits been detected bodies worldwide. wastewater (contaminated with pesticides) has negative impacts on human health, ecosystem, aquatic environment. Recently, biodegradable biocompatible (including plant-based) introduced green safe products reduce/eliminate synthetic pesticides. Despite positive advantages biopesticides, limited due cost slow interaction pests compared chemical Pesticides may also react constituents soil resulting formation intermediates having different physical properties. Diffusion, dispersion, permeation main mechanisms transfer water. degrade naturally nature; however, time requirement can be very long. Many mathematical models developed simulate estimate final fate resources. Development new technologies environmentally friendly reduce contamination increasingly important.
