Environmental sampling is the process of collecting samples from various environments, such as air, water, soil, and sediments, to analyze their quality and composition. This practice helps scientists and researchers understand the presence of pollutants, microorganisms, and other substances that may affect ecosystems and human health. The samples collected can be tested for a range of factors, including chemical contaminants, biological organisms, and physical properties. By studying these samples, experts can assess environmental conditions, track changes over time, and inform policies aimed at protecting natural resources and public health.
