Trong thập kỷ vừa qua một số lượng lớn quan tâm đã phát sinh liên quan đến sự xuất hiện và số phận của các dấu vết chất gây ô nhiễm hữu cơ trong môi trường nước. Trong số đặc biệt mối quan tâm là kích thích tố con người và dược phẩm, trong đó có nhiều ở khắp mọi nơi chất gây ô nhiễm trong nhà máy thông thường, thành phố trực thuộc Trung ương xử lý nước thải chất thải khi đo với giới hạn phát hiện ng / L. Khi các thủ tục phân tích và kỹ thuật sinh thử nghiệm trở. | 11 Removal of Endocrine Disruptors and Pharmaceuticals during Water Treatment Shane A. Snyder Hongxia Lei and Eric C.

Of particular concern are human hormones and pharmaceuticals many of which are ubiquitous contaminants in conventional municipal wastewater treatment plant effluents when measured with ng L detection limits. As analytical procedures and bioassay techniques become more readily available and increasingly sensitive new contaminants will be discovered. The presence or absence of any chemical in a wastewater effluent is essentially a function of analytical detection capability. This poses a unique challenge for drinking water treatment plants intent on the removal of organic contaminants as complete removal is merely a reflection of reporting limits. The project described in this chapter was designed to investigate the attenuation of a group of structurally diverse emerging contaminants by conventional and advanced water treatment processes. 229 2008 by Taylor Francis Group LLC 230 Fate of Pharmaceuticals in the Environment and in Water Treatment Systems These data represent a portion of the findings from a study sponsored by the American Water Works Association Research Foundation AwwaRF entitled Removal of EDCs and Pharmaceuticals in Drinking and Reuse Processes Project 2758 .
