What are the sources effects and control measures of marine pollution?

The marine environment becomes polluted and contaminated through various sources and forms. Major sources of marine pollution are the inflow of chemicals, solid waste, discharge of radioactive elements, industrial and agricultural effluents, man-made sedimentation, oil spills, and many such factors.

What is the source of marine pollution?

Most ocean pollution begins on land. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.

What are the effects of marine pollution?

Other specific effects of ocean pollution on sea life include: Oil covering the feathers of birds and the gills of fish. Skin and eye irritation and lung and liver problems from oil deposits and byproducts. Reproductive system failure from exposure to poisonous industrial and agricultural chemicals.

What are the 3 sources of marine pollution?

The annexes covers a wide range of potential marine pollution sources, ranging from ship-generated fuel oil residues, bilge water, sewage and air pollution to cargo residues such as ballast water oil, wash water chemicals and dry cargo residue. In addition, Marpol includes a Code for ships operating in Polar Waters.

What are the causes and effects of water pollution?

Causes of Water Pollution. Many industries dump industrial waste, such as hazardous chemicals, into bodies of water before treatment. It eventually pollutes the water. The dumping of hazardous substances reduces the oxygen levels in the water, resulting in pollution.

What are the sources and effects of pollution?

There are four main types of air pollution sources: mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.

What is pollution and sources of pollution?

Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
