Natureを読む[April-1]

まず、読み易い記事からはじめましょう。医学、理学用語はあまり出てこないのですが・・・
なお、参加には、該当雑誌の講読が前提になります。

    The city's sewers each day soaks up its citizens' routines, taking in a steady stream of products. Toothpaste and shampoo may be harmless enough, but the waste also collects a wide array of medicines people take. Most drugs are poorly absorbed and metabolized by the body, so it is not unusual that the majority of a drug would end up intact in the urine. Because all water goes through toilets at some point, these artificial compounds, some quite difficult to break down, can eventually find their way into the city's water supply---even bottled water.
