研究表明 多国自来水被塑料污染
Microplastic contamination has been found in tap water in countries around the world, leading to calls from scientists for urgent research on the implications for health. Scores of tap water samples from more than a dozen nations were analyzed by scientists for an investigation by noNPRofit organization Orb Media. Overall, 83% of the samples were contaminated with plastic fibers. The US had the highest contamination rate, at 94%. Lebanon and India had the next highest rates. European nations including the UK, Germany and France had the lowest contamination rate, but this was still 72%. "We don't know what the health impact of microplastic is," said Anne Marie Mahon at the Galway-Mayo Institute of Technology. Microplastics can attract bacteria in sewage. Mahon said: "Some studies have shown there are more harmful pathogens on microplastics downstream of wastewater treatment plants." |
