Water pollution policies proposed

HÀ NỘI – The water quality of lakes, rivers, streams and canals in Việt Nam is seriously degrading. Water in urban areas and industrial zones poses risks to human and aquatic animals.

Rivers such as Tô Lịch, Sét and Kim Ngưu in Hà Nội have become sections of the city’s waste water drainage system.

The information was revealed yesterday in a water pollution report conducted by the Coalition for Clean Water and the Centre for Environment and Community Research (CECR) under the Việt Nam Union of Science and Technology Organisations.

How plastic water bottles could harm your health

In a recent study, researchers from Texas A&M found that exposure to dietary exposure to bisphenol-A, or BPA can worsen symptoms of inflammatory bowel disease.

This is the first study to show that BPA can negatively impact gut microbial amino acid metabolism in a way that has been associated with irritable bowel disease.

Irritable bowel disease, or IBD, is a complex collection of diseases that include ulcerative colitis and Crohn’s disease.

Ho Chi Minh City spills 30 percent of clean water through leaking pipes

Thousands of families in outlying districts are forced to depend on ground water.

Ho Chi Minh City lost nearly 30 percent of its clean water in 2016 through leaking and broken pipes, according to a new report from the city's utility company.

Saigon Water Corporation (Sawaco) said it delivered around 630 million cubic meters of clean water last year, but some people were still unable to turn on the taps.

Plastic: WHO launches health review

The World Health Organization is to launch a review into the potential risks of plastic in drinking water.

It will assess the latest research into the spread and impact of so-called microplastics - particles that are small enough to be ingested.

It comes after journalism organisation Orb Media found plastic particles in many major brands of bottled water.

There is no evidence that microplastics can undermine human health but the WHO wants to assess the state of knowledge.

Plastic particles found in bottled water

Tests on major brands of bottled water have found that nearly all of them contained tiny particles of plastic.

In the largest investigation of its kind, 250 bottles bought in nine different countries were examined.

Research led by journalism organisation Orb Media discovered an average of 10 plastic particles per litre, each larger than the width of a human hair.

Companies whose brands were tested told the BBC that their bottling plants were operated to the highest standards.

The tests were conducted at the State University of New York in Fredonia.

Brain damage in fish from plastic nanoparticles in water

Calculations have shown that 10 per cent of all plastic produced around the world ultimately ends up in the oceans. As a result, a large majority of global marine debris is in fact plastic waste. Human production of plastics is a well-known environmental concern, but few studies have studied the effects of tiny plastic particles, known as nanoplastic particles.

 

"Our study is the first to show that nanosized plastic particles can accumulate in fish brains," says Tommy Cedervall, a chemistry researcher at Lund University.
