- Household waste
- Wastewater
- Stormwater
- Aerosol

Microbiological pollution:
- Bacilli (typhoid)
- Virus (viral hepatitis) from sewage discharged into rivers and the sea
- Contamination of swimmers and shellfish beds.

Human pollution:
Spill:
- Liquid whose temperature is higher than the environment (plant, power station …) whose effects alter the habitat (algae, disappearance of certain species of fish, the appearance of others …)
- Off silt-laden water (central hydroliques in the draining, mining aggregate)

Industrial Pollution:
- Organic solvents
- Oils
- Hydrocarbons
- Heavy metals
- Thermal discharges warm water from nuclear power stations in rivers (killing animals)

Agriculture:
- Fertilizers
- Insecticides
- Pesticides
- Intensive livestock contamination is through runoff and seepage into groundwater.

Accidental pollution:
- Oil spills
- Road accident
- Human error
- Disbursement untimely

Pollution is the degradation of habitat through the introduction, usually human, substances or radiation, causing a disturbance more or less important to the ecosystem. It can also be caused by a geological phenomenon as a volcanic eruption.
The pollution of human origin can have a major impact on the ecosystem as evidenced by the warming climate that transforms the atmosphere of the Earth and its ecosystem, resulting in the emergence of diseases previously unknown in certain geographical areas, migration of certain species or their extinction if they can s’ to adapt to their new biophysical environment.

It was after the Second World War that awareness of human impact on the environment is created through the birth of environmentalism. Environmental concerns led governments to take measures to reduce the ecological footprint of human populations, pollution and to counter human contamination.
