Development of Biosorbent to Eliminate the Consequences of Hydrocarbon Pollution at Oil and Gas Facilities

The article presents the results of ecological risk management in the elimination of the consequences of hydrocarbon pollution at oil and gas facilities using the developed biosorbent based on hydrophobized peat and hydrocarbon-oxidizing microorganisms.

Input-output model based ecological risk assessment for ecological risk management of watersheds: a case study in the Taihu Lake watershed, China

To achieve advanced watershed ecological management, policy-makers have struggled to predict ecological impacts for a long time. As a process of ecosystem analysis, ecological risk assessment (ERA) has been widely adopted to analyse the possibility of adverse ecological effects. ERA has developed from considering only a few indicators in an area to multiple sources and receptors in large-scope regions. However, the transfer of risk in large-scope regions caused by internal interaction has not been deeply analysed, especially in regions with complex internal interaction structures. This would lead to extensive management, where watershed-level policies may not be fit for some subregions, thus leading to limited management efficiency. In this study, we integrate an Input-Output (IO) model into the Relative Risk Model (RRM), and propose an IO model based ERA (IO-ERA) methodology, which would reveal the intensity of ecological risk caused by local sources, direct water flows and indirect transfers. An IO-ERA is conducted in Taihu Lake watershed as a case study, in which we could demonstrate that IO-ERA is capable of providing advanced insights of risk analysis in large-scope regions. The outcome of IO-ERA would support watershed administration to transfer from single standard regulation to diverse, dynamic and lean ecological risk management.

Review of Study of Ecological Risk Management

With the development of society, the ecological risks continue to produce; ecological risk management is becoming urgent. This paper uses the literature research methods, focusing on the origin of ecological risks, the arising of ecological risk management, the ecological risk assessment model, and the relationship between ecological risk assessment and ecological risk management. Based on research at home and abroad, the paper proposes shortcomings of current research and three areas for further study in the future.
