A review of atmospheric benzene homologues in China: Characterization, health risk assessment, source identification and countermeasures

Benzene homologues are important chemical precursors to the formation of ground-level ozone and secondary organic aerosol(SOA) in the atmosphere,in addition,some toxic species are harmful to human health.Strict countermeasures have been taken to fight air pollution since 2013,and total amount control of volatile organic compounds is being promoted in China at present.Therefore,it is important to understand the pollution situation and the control status of ambient benzene homologues in China.This...     

Strategic pollution control and capital tax competition

In an analytical model of symmetric countries with mobile capital and local or transboundary pollution we investigate whether competition in emissions taxes (or emissions caps) and capital taxes leads to efficient outcomes when governments act strategically. When they have capital taxes and emissions caps at their disposal, they refrain from taxing capital and set their caps inefficiently lax [efficient] for transboundary [local] pollution. When they have the option to tax capital and emissions, capital is subsidized [untaxed] and emissions taxes are inefficiently low [efficient] for transboundary [local] pollution. In case of transboundary pollution emissions caps are Pareto-superior to emissions taxes. That holds regardless of whether the environmental policy is applied as stand-alone policy or combined with capital tax competition.     

Effects of a major municipal effluent on the St. Lawrence River: A case study

The St. Lawrence River (SLR) is the second largest waterway in North America. The discharge of the City of Montreal wastewater treatment plant (WWTP) represents the largest volume of treated wastewaters being released into the river. It also ranks as the largest sewage treatment plant of its kind in North America. Over the last decade, intensive multidisciplinary research has focused on assessing the impacts of Montreal wastewater effluents on the SLR. We describe the major findings of these investigations, including the determination of the fate of contaminants, bioaccumulation in fish and invertebrates, ecotoxicological measurements of aquatic animal health, evaluation of endocrine disruption, parasitism in fish, and combined effects of multiple stressors on the SLR. Impacts of the effluents from the WWTP on aquatic organisms from the SLR are both toxicological and ecological, demonstrating the need for an integrated view of the impacts of municipal effluents on aquatic ecosystems.
