The Advantages and Disadvantages of Pesticides

Pesticides can cause short-term adverse health effects, called acute effects, as well as chronic adverse effects that can occur months or years after exposure. Examples of acute health effects include stinging eyes, rashes, blisters, blindness, nausea, dizziness, diarrhea and death. Examples of known chronic effects are cancers, birth defects, reproductive harm, neurological and developmental toxicity, immunotoxicity, and disruption of the endocrine system. Some people are more vulnerable than others to pesticide impacts. For example, infants and young children are known to be more susceptible than adults to the toxic effects of pesticides.

Our populous, fast-paced world demands quality food that is affordable — and lots of it. In the short term, pesticides greatly assist pest control. In the long term, however, pesticides appear to harm the health of humans and the environment. A pesticide is any substance or mixture of substances whose purpose is to prevent, extinguish, or repel pests or to regulate plants. There are considerable benefits to pesticide use.

The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. Among these, organochlorine OC insecticides, used successfully in controlling a number of diseases, such as malaria and typhus, were banned or restricted after the s in most of the technologically advanced countries. The introduction of other synthetic insecticides — organophosphate OP insecticides in the s, carbamates in s and pyrethroids in s and the introduction of herbicides and fungicides in the s—s contributed greatly to pest control and agricultural output.

Pesticides: Environmental Impacts and Management Strategies

Toxicology Studies - Cells, Drugs and Environment. Pesticides constitute any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest. They can also serve as plant regulators, defoliants, or dessicants [ 1 ]. Chemicals have long been used to control pests. Sumerians already employed sulfur compounds to control insects and mites years ago. Pyrethrum, a compound derived from the dried flowers of Chrysanthemum cinerariaefolium , has been applied as an insecticide for over years.

Pesticides, also known as pest control products, control, destroy or inhibit the activities of pests, and minimize their injurious, noxious or troublesome effects. If not properly managed, pests can affect our quality of life in many different ways. Pests can represent a threat to public health and the environment as well as create significant negative impacts to the economy if they are not efficiently controlled. The availability and use of pesticides have the potential to pose risks, both directly and indirectly, to the health, safety and well-being of people in Canada, and to the environment. As such, pesticides are highly regulated products. Pesticides have a wide range of intended uses in agriculture e.


Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.
