マイクロプラスチック　Sewage treatment plants　3

However, it is important to note that in certain countries sewage sludge is used for soil fertilizer, which exposes plastics in the sludge to the weather, sunlight, and other biological factors, causing fragmentation. As a result, microplastics from these biosolids often end up in storm drains and eventually into bodies of water. In addition, some studies show that microplastics do pass through filtration processes at some WWTPs (Microplastics as Contaminants, 2011). According to a study from the UK, samples taken from sewage sludge disposal sites on the coasts of six continents contained an average one particle of microplastic per liter. A significant amount of these particles was of clothing fibers from washing machine effluent.

ただし、特定の国では下水汚泥が土壌肥料に使用され、汚泥中のプラスチックが天候、日光、およびその他の生物学的要因にさらされ、断片化を引き起こすことに注意することが重要です。

その結果、これらのバイオソリッドからのマイクロプラスチックは、しばしば雨水排水溝に行き着き、最終的には水域に入ります。
さらに、いくつかの研究は、マイクロプラスチックがいくつかのWWTPでろ過プロセスを通過することを示しています（Microplastics as Contaminants、2011）。

According to a study from the UK, samples taken from sewage sludge disposal sites on the coasts of six continents contained an average one particle of microplastic per liter.
英国の調査によると、6大陸の海岸にある下水汚泥処理場から採取したサンプルには、1リットルあたり平均1個のマイクロプラスチック粒子が含まれていました。

A significant amount of these particles was of clothing fibers from washing machine effluent.
これらの粒子のかなりの量は、洗濯機排水からの衣類の繊維でした。
