That's called atmospheric deposition. When farmers fertilize the fields, the chemicals they use are gradually washed by rain into the groundwater or surface waters nearby and contaminate the water. SEWAGE Sewage disposal affects people's immediate environments and leads to water-related illnesses such as diarrhea that kills 760,000 children under five each year. When you flush the toilet, the waste has to go somewhere and, even after it leaves the sewage treatment works, there is still waste to dispose of. Sometimes sewage waste is pumped untreated into the sea. NUTRIENTS Suitably treated and used in moderate quantities, sewage can be a fertilizer Chemical fertilizers used by farmers also add nutrients to the soil, which drain into rivers and seas and add to the fertilizing effect of the sewage. Together, sewage and fertilizers can cause a massive increase in the growth of algae or plankton that overwhelms huge areas of oceans, lakes, or rivers. This is known as a harmful algal bloom. Highway Runoff A lot of toxic pollution also enters waste water from highway runoff. Highways are typically covered with a cocktail of toxic chemicals—everything from spilled fuel and brake fluids to bits of worn tyres and exhaust emissions. When it rains, these chemicals wash into drains and rivers. Chemical waste Detergents and many chemicals used in manufacturing units also pollute the surface and ground water. Another kind of toxic pollution comes from heavy metals, such as lead (commonly used in gasoline) cadmium, and mercury (commonly used in battery). Radioactive waste At high enough concentrations it can kill; in lower concentrations it can cause cancers and other illnesses. The biggest sources of radioactive pollution can be seen in places where factories reprocess waste fuel from nuclear power plants. Oil pollution Huge black oil slicks represent only a tiny fraction of all the pollution entering our oceans. Only 12 percent of the oil that enters the oceans comes from tanker accidents; over 70 percent of oil pollution at sea comes from routine shipping and from the oil people pour down drains on land. Plastics Plastic is far and away the most common substance that washes up with the waves and present a major hazard to seabirds, fish, and other marine creatures. For example, plastic fishing lines and other debris can strangle or choke fish. Alien species Alien species are animals or plants from one region that have been introduced into a different ecosystem where they do not belong. Outside their normal environment, they have no natural predators, so they rapidly run wild, crowding out the usual animals or plants that thrive there. Common examples of alien species include zebra mussels in the Great Lakes of the USA, which were carried there from Europe by ballast water (waste water flushed from ships). Do not throw garbage in the water….. Keep it clean now and later. |
