They are even appearing inside humans. 【2】Now, new research suggests that a simple, cheap measure may significantly reduce the level of microplastics in water from your tap (水龙头): boiling and filtering (过滤) it. In a study published Wednesday in Environmental Science & Technology Letters, researchers from China found that boiling tap water for just five minutes—then filtering it after it cools—could remove at least 80 percent of its microplastics. 【3】Crucially, this process relies on the water containing enough calcium carbonate (碳酸钙) to trap the plastics. In the study, boiling hard water containing 300 milligrams of calcium carbonate led to an almost 90 percent drop in plastics. But in samples with less than 60 milligrams of calcium carbonate, boiling reduced the level of plastics by just 25 percent. Additionally, the research didn’t include all types of plastics. The team focused only on three common types—polystyrene, polyethylene and polypropylene—and they didn’t study other chemicals previously found in water such as vinyl chloride. 【4】Still, the findings show a potential path forward for reducing microplastic exposure—a task that’s becoming increasingly difficult. Even bottled water, scientists found earlier this year, contains 10 to 1,000 times more microplastics than originally thought. 【5】Scientists are still trying to determine how harmful microplastics are—but what they do know has raised concerns. The new study suggests boiling tap water could be a tool to limit intake. “The way they demonstrated how microplastics were trapped through the boiling process was nice,” Caroline Gauchotte-Lindsay, an environmental engineer at the University of Glasgow in Scotland who was not involved in the research, tells New Scientist. “We should be looking into upgrading drinking water treatment plants so they remove microplastics.” 话题介绍：微塑料已经成为地球上常见的污染源 中国方案：自来水煮沸五分钟后过滤 专家建议 （一）文章结构与逻辑--科普说明文：微塑料污染治理 关键局限 现实意义 全文遵循“问题呈现→方案提出→辩证分析→现实关联→未来建议”逻辑，层层递进，传递“微塑料治理任重道远，但已有可行探索”的科学认知。 （二）语言与知识亮点 1. 词汇：专业术语（microplastics、calcium carbonate ）、高频学术词（source、pollution、reduce、remove ）、熟词生义（hard water指“高钙水” ），考查学生词汇深度理解； 2. 句式：长难句密集（如“boiling tap water for just five minutes—then filtering it after it cools—could remove at least 80 percent of its microplastics.” ），训练学生语法分析与信息提取能力； 3. 体裁特征：科普文“客观陈述 ... ...
