While many of us have heard of the environmental damage done by plastic，fewer people know about the threat1 from the ubiquity2 of microplastics.Worryingly， Chinese researchers have now found them in the human heart. Thescientists in China collected samples3 from 15 patients undergoing heart surgery4.They discovered tiny pieces of plastic.

雖然我們很多人都已經(jīng)聽說過塑料對環(huán)境的破壞，但很少有人知道微塑料無處不在的威脅。令人擔憂的是，中國的研究人員現(xiàn)在已經(jīng)在人類心臟中發(fā)現(xiàn)了它們。中國的科學家從15 名接受心臟手術(shù)的患者身上采集了樣本。他們發(fā)現(xiàn)了微小的塑料碎片。

The scientists reported finding， “tens to thousands of individual microplasticpieces in most samples”. They may lead to cancer， cell death， and so on.Microplastics are everywhere. They make up 39 per cent of dust particles5 in ourhomes. Scientists say these tiny pieces are near-impossible to remove from thebody. They say it is important to limit the amount of plastic we eat or breathe in.

科學家們報告這一發(fā)現(xiàn)說，“在大多數(shù)樣本中都有數(shù)以萬計的微塑料碎片”。它們可能導致癌癥、細胞死亡等。微塑料到處都是。它們占我們家中灰塵顆粒的39%。科學家們表示，這些微小的碎片幾乎不可能從人體中清除。他們說，限制我們攝入或吸入的塑料量變得至關重要。
