塑料污染

Chinese scientists have developed a plastic that degrades in seawater and could help curb the increasingly serious plastic pollution in the oceans.我国科学家前不久研发出一种可在海面中水解的塑胶,或将有助操控日趋严重的海洋塑料污染难题。The new polyester composite material can decompose in seawater over a period ranging from a few days to several hundred days, leaving small molecules that cause no pollution, said Wang Gexia, a senior engineer at the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences.中国研究院化学系技术性研究室工程师职称王格侠解读,这类新式的聚脂高分子材料可在数日到百余天本质海里水解,最终溶解变成会对自然环境造成 环境污染的小分子水。For a long time, people focused on white pollution on land. Plastic pollution in the seas only caught peoples attention when more and more reports about marine animals dying from it appeared in recent years, said Wang.王格侠答复:“一直以来大家注目的全是陆上上的白色垃圾。

之后近些年,相关海洋微生物因塑料污染丧命的报道更为多,海洋塑料污染才引起大家的注目。”Scientists combined non-enzymic hydrolysis, water dissolution and biodegradation processes to design and invent the new material.生物学家将非酶胆水解、水沉定和降解的全过程联络一起,设计方案并发明人了这类新材料。About 4.8 million to 12.7 million ton of plastic waste goes into the seas very year, accounting for 60% to 80% of the total solid pollutants in the oceans, according to a conservative estimate by scientists.据生物学家激进派估计,人们每一年向海洋废置的塑料垃圾大概为480万至1270万吨级,占到海洋液體空气污染物总产量的60%-80%。The institute has authorized four Chinese enterprises to use their technology, with three enterprises going into production with a total annual capacity of half the global biodegradable plastics, or 75,000 tons.现阶段,该研究室已批准4家中国公司用以其技术性,在其中3家早就建成投产,可微生物降解塑料总生产量超出每一年7.五万吨,占到全世界总产量的一半。

China has given top priority to ecological environmental protection, contributing Chinese wisdom to resolving global pollution.中国早就将绿色生态生态环境保护放进了第一位,为解决困难全世界环境污染难题奉献了中国的聪慧。
