Contamination can arise fromcertain manifestations of nature ( natural sources ) or due to the different production processes of man ( anthropogenic sources ) that make up daily life activities .
Sources generating more anthropogenic pollution are: industrial (refrigerators , slaughterhouses and tanneries , mining and oil ) , commercial ( wrappers and packaging ) , agricultural (agrochemicals ) , home ( bottles , diapers, gardenwaste ) and sources mobile ( car exhaust ) . As emission source means the physical or geographical origin where there is a contaminant release to the environment , either to air, water or soil . Traditionally the environment has been divided for study and interpretation , in these three components: air , water and soil , but this division is purely theoretical , since most of the pollutantsinteract with more than one of environmental elements .
