摘要
•Oil sands process-affected water (OSPW) is generated as a by-product in the bitumen extraction process. It is stored in man-made reservoirs on mining sites.•OSPW forms a complex mixture of biotic and abiotic components that vary due to multiple factors.•Abiotic components such as naphthenic acids (NAs), inorganic ions, and residual bitumen all contribute to the toxicity of OSPW in vivo and in vitro. The microbial community are involved in the biogeochemical cycling of nutrients in addition to the bioremediation of OSPW.•Both the biotic and chemical constituents of OSPW should be considered to properly treat OSPW and to understand its toxicity.
