The soil samples were analyzed for 23 kinds of organochlorine pesticides (OCPs) using a gas chromatography electron capture detector device. Persistent pesticides, which primarily consist of organochlorine pesticides, are considered persistent because they are stable in the environment and resist being broken down. At the pH of slightly acidic soils (pH 4 to 5), these half-lives will be extended many times. Figure 2.
