摘要
从处理过的城市废水中向淡水系统排放营养物质、有机微污染物和抗生素抗性基因的复杂混合物是全球人类健康和水生生物关注的问题。抗生素抗性基因 (ARG) 是能够赋予抗生素抗性并降低抗生素在其所在系统中的功效的基因。在加拿大马尼托巴省 Grand Marais 的农村社区,废水在通过处理湿地之前在污水泻湖中被动处理,然后排放到地表水中。使用该设施作为加拿大大草原的模型系统,本研究的两个目标是评估:(a) 泻湖产出中营养物质、微污染物(即杀虫剂、药物)和 ARGs 的存在,以及(b)它们的在 2012 年释放到地表水之前,处理湿地可能会去除。
Discharging a complex mixture of nutrients, organic micro-pollutants and antibiotic resistance genes into freshwater systems from treated urban wastewater is a global concern for human health and aquatic organisms. Antibiotic resistance gene (ARG) is a gene that confers resistance to antibiotics and reduces the efficacy of antibiotics in their system. In a rural community in Grand Marais, Manitoba, Canada, wastewater is passively treated in a sewage lagoon before passing through treatment wetlands and then discharged into surface water. Using this facility as a model system for the Canadian prairie, the two goals of this study are to evaluate: (a) the presence of nutrients, micropollutants (ie pesticides, drugs) and ARGs in the output of the lagoon, and ( b) They may be removed from treated wetlands before they are released to surface water in 2012.
