Contamination is the introduction of contaminants into the natural environment, causing damage to them and causing disturbance in the ecosystem. These pollutants are either exogenous to the environment or natural materials, but their levels exceed accepted levels. The pollution is not only associated with chemicals but also includes pollution in various forms of energy such as noise pollution And thermal pollution.
