Abstract
Agrochemicals have been used for many years to manage agricultural pests and diseases. However, their prolonged use has led to harmful effects on human health and environmental organisms. This review highlights the impact of agrochemicals, particularly pesticides and fertilizers, and their potential risks to both human well-being and ecological balance. It is very difficult to educate and train farmers on the proper use of agrochemicals in high-population, developing countries. Agrochemicals are classified into inorganic pesticides and fertilizers, which are used to increase crop yield and control diseases, pests, and weeds. Pesticides include insecticides, fungicides, and herbicides, while fertilizers consist of macronutrients (such as NPK) and micronutrients (such as Zinc and Iron). The main focus of this review is to classify agrochemicals and examine their effects on human health (such as chronic and acute illnesses, cancer, neurological disorders, reproductive harm, anemia, and birth defects) as well as their environmental impact on non-targeted plants, animals, soil fertility, and water contamination. Studies related to the prevalence of agrochemicals are also discussed. This review is based on secondary data, descriptive analysis, and previously available relevant literature, including journals, magazines, and e-resources. The findings suggest that the government should regulate the use of agrochemicals, imposing limitations, and focus more on biological methods for agriculture rather than chemical alternatives, due to the harmful effects of agrochemicals.
