[0002] Water samples from contaminated water bodies are collected and analyzed to obtain basic data on water pollution. Water samples for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, location, time, and frequency are determined based on the characteristics of the water body and the purpose of the analysis. Water quality samplers for terrestrial water bodies are mostly bottle-type, consisting of a water sampling container, a water pipe, and a sounding rope. The water sampling container should be a chemically stable glass bottle or a polytetrafluoroethylene or polyethylene plastic bottle with a ground glass stopper or plastic cap to prevent leakage and infiltration of impurities.
