The main sources of pollution are household activities, factories, agriculture and transport. Once they have been released into the environment, the concentration of some pollutants is reduced by dispersion, dilution, deposition or degradation. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution.
