俄俄州的农场正在安装新的过器, 在它们到达伊利湖之前捕获有害营养物质. New phosphorus filters are being installed on Ohio farms to capture harmful nutrients before they reach Lake Erie. 这些大型系统主要针对高污染的田地,其中很少有土地会导致排水,并几乎消除所有溶解反应. These large systems target high-polluting fields, where a small percentage of land contributes to runoff, and remove nearly all dissolved reactive phosphorus. 预计这些过器将持续十年, 并有助于减少有害藻类的繁殖. The filters are expected to last a decade and help reduce harmful algal blooms.
