摘要: This study investigated the occurrence of oxytetracycline (OTC) and emamectin benzoate (EB) in sediments located near effluent outfall from four freshwater aquaculture facilities Atlantic Canada. While two had no detectable concentrations EB or OTC, one both these chemicals. Concentrations ranged <0.05–18 mg/kg to <0.01–2.5 for OTC respectively. Although values could not be compared with toxicant values, some detected were higher than LC50 calculated marine invertebrates. measured this are also a magnitude which has been known produce resistant bacteria.
