Pesticides: Positive and Negative Aspects and their Treatment in Wastewater



Pesticides: Positive and Negative Aspects and their Treatment in Wastewater

Qamruzzaman, A. Nasar

The use of a wide variety of pesticides to prevent, destroy, repel or control pests has become an essential practice in the agricultural field as well as in our daily domestic life. Nowadays, a variety of pesticides is available to suit specific requirement for the agricultural and domestic purposes. In order to fulfill the increasing demand of agricultural foods, pesticides are being used all over the world. Unquestionably, the use of pesticides has increased crop yield and provided an economic benefit to the farmers. However, the extensive use of these pesticides has resulted in their presence in foods, water resources, soils and atmosphere in many forms. Consequently, this has led to concern over the harmful effects of pesticides on human and other living organisms. In the present chapter, the classification of pesticides on the basis of target organisms as well on the basis of sources has been discussed. Various advantages and disadvantages of the pesticides have been highlighted. As the pesticides are generally formulated before being sent to market, the formulations of pesticides have also been briefly discussed. The available treatment methods employed for the detoxification of pesticides from the contaminated wastewater are reviewed in light of current available literature.
