Cause of sea and river pollution

Share via Email This article is over 6 months old Plastic pollution is known to harm marine life and can enter the human food chain via our food and water. The work reveals the highest microplastic pollution yet discovered anywhere in the world in a river near Manchester in the UK.

It also shows that the major floods in the area in flushed more than 40bn pieces of microplastic into the sea. The surge of such a vast amount of microplastic from one small river catchment in a single event led the scientists to conclude that the current estimate for the number of particles in the ocean — five trillion — is a major underestimate.

Microplastics include broken-down plastic waste, synthetic fibres and beads found in personal hygiene products.

They are known to harm marine life, which mistake them for food, and can be consumed by humans too via seafood, tap water or other food.

The risk to people is still not knownbut there are concerns that microplastics can accumulate toxic chemicals and that the tiniest could enter the bloodstream.

Microplastics map The team analysed sediments in 10 rivers within about 20km of Manchester and all but one of the 40 sites showed microplastic contamination.

Of those, about 17bn would float in sea water. The worst hotspot, on the River Tame, had more thanmicroplastic particles per square metre in the top 10cm of river bed.

But Hurley said there may well be worse places yet to me measured: This high proportion surprised the scientists, who said the beads may well also derive from industrial uses, which are not covered by the ban.

Erik van Sebille, at Utrecht University in the Netherlands and and not part of the research team, said the work does support a much higher estimate of global microplastic pollution in the oceans: Is it on beaches, the seafloor, in marine organisms? The missing gap is we need to know if we are getting contaminants inside us as a result of plastic particles.

But much smaller plastic particles will exist, and Hurley said:What causes water pollution? Let us find out how sewage and waste water, septic tanks, ocean and marine dumping, industrial waste, oil spilling, underground storage and tbue leakage, as well as atmospheric action can cause water pollution.

It is estimated that 65 percent of the pollution in Pasig River comes from household waste. In a third world country where many of the homes do not have indoor plumbing, the river is a place to dump some of the tons of wastewater produced daily by Metro Manila’s citizens.

What is Ocean Pollution? Oceans are the largest water bodies on the planet Earth. Over the last few decades, surplus human activities have severely affected the marine life on the Earth's oceans. Ocean pollution, also known as marine pollution, is the spreading of harmful substances such as oil, plastic, industrial and agricultural waste and chemical particles into the ocean.

There are several causes of water pollution in India. The main causes are briefly described as under: 1.

Water and Air Pollution - HISTORY

Urbanisation. Rapid urbanisation in India during the recent decades has given rise to a number of environmental problems such as water supply, wastewater generation and its . Other causes of water pollution.

Apart from the industrial causes of water pollution, as we saw on the previous page, here are some more: Sewage and waste water Every day, we cook, do laundry, flush the toilet, wash our cars, shower and do many things that use water.

Factories use water from rivers to power machinery or to cool down machinery. Dirty water containing chemicals is put back in the river. Water used for cooling is warmer than the river itself, and this is also a .
