Chemical treatment refers to the use of chemicals to alter the properties of a substance or to remove unwanted materials. This process is commonly used in various industries, including water treatment, where chemicals help to purify water by eliminating contaminants and pathogens. In agriculture, chemical treatment involves applying fertilizers and pesticides to enhance crop growth and protect plants from pests. These chemicals can improve soil quality and increase agricultural productivity, but they must be used carefully to minimize environmental impact and ensure safety for humans and wildlife.
