| Abstract: | Accompanied with rapid growth of shale gas industry,associated environmental problems have received continuous attention from the academia and public.Shale gas production is tightly linked to regional water resources.Specifically,shale gas extraction is consuming huge amount of fresh water resources,and the produced wastewater also contain thousands of chemical components.Thus,the relevant studies focusing on organic pollutants in the flowback water are receiving increasing interests.Our study summarizes the information on types,sources,concentration levels and harmful health effects of various organic pollutants introduced during shale gas production.Specially,the known persistent,mobile and toxic compounds(PMT)detected in flowback water,which are less sorptive but persistent,which could accumulate in drinking water resources and groundwater aquifers,were exemplified.Also,the potential impact on the regional drinking water resources and groundwater quality were demonstrated.Lastly,given that chemical pollution associated with shale gas production in China is still in early stage,our study also provided outlook for future studies. |
