Pesticides are substances that are used for controlling, repelling, mitigating or killing pests that are harmful to man. Some of the pesticides that have been used include but not limited to herbicides, insecticides, fungicides and rodenticides. Most of these pesticides can be grouped in three groups of pesticides namely, oregano-chloride, organo-phosphates and carbamates. Some of the characteristics of these pesticides include toxicity, persistence and bioaccumulation. The application of pesticides affects both the targeted as well as the non-targeted species including man. The parent pesticides, their degradation products together with metabolites can be harmful to the environment, ecosystem and to the human health. Due to this the aim of this study was to look into the articles studied on the impact of pesticide pollution on the environment, ecosystem as well as on human health. This was done by assessing both the benefits, effects and risks associated with the continuous use of pesticides as well as ways to mitigate the pesticides pollution problems. The methodology used in the study to look for the review articles was through the internet by going through websites which include Google, Google Scholar and PUBMED. About 70 studies were retrieved which included articles and abstracts. Books from the library with relevant information about the study were also included. The reviewed studies have revealed that there are benefits and risks as well as effects of pesticides pollution on environment. The studies have also revealed that in order to control pesticide pollution, the use of other methods of controlling pests such as integrated pest management (IPM) strategies such as biological as well as cultural could be used to control pests instead of chemical pesticides.
