A new study from Newcastle university in Australia shows that plastic pollution has entered the human body.The average person in the world consumes nearly 5 grams of microplastics per week, the same amount as a credit card, and about 250 grams per year.
Microplastics are irregular plastic particles with particle size less than 5 mm, which are widely found in oceans, rivers and other water bodies around the world.Toxic substances contained in the microplastics themselves and absorbed in the water can accumulate through the food chain and eventually enter the human body, threatening human health.
The study, commissioned by the world wide fund for nature (WWF) at the university of Newcastle in Australia, combined data from more than 50 studies on microplastics.According to the report, the average person in the world consumes 1,796 microplastics per week through drinking water alone.
The report says the largest source of human consumption of microplastics is drinking water, which is found in bottled water, tap water, surface and groundwater worldwide.In foods, crustacean seafood, beer, and salt have more microplastic particles *.
The study shows that while the levels of plastic pollution vary from country to country, few areas are immune.Among them, 94.4% of tap water samples in the United States contain plastic fiber, with an average of 9.6 fibers per liter of water.72.2 per cent of the sampled water in Europe contained plastic fibres, with an average of 3.8 per litre.
The global consumption of plastic since 2000 is equivalent to that of all previous years combined, with a third of it dumped in the natural environment, the report said.
WWF global director general Marco lambertini says plastic pollution is a pressing global problem, not only contaminating oceans and waterways and killing Marine life, but also in everyone.He urged governments, businesses and consumers to act together and draw up international rules to tackle plastic pollution at its source.
