Does environmental risk really change in abandoned mining areas in the medium term when no control measures are taken?

ABSTRACT Following the 2010 Deepwater Horizon (Macondo) oil spill incident it became clear that further focus is required in order to understand and control blowout risks. The control measures are also essential in reducing potential environmental consequences given a blowout event. The latest development in well capping techniques indicates that this might be a viable technical solution for controlling subsea oil and gas well blowouts. The limited field experience with this technology makes it however difficult to presume the effectiveness of the technology as an environmental risk reducing measure. It is assumed that successful implementation of a capping device, given a subsea blowout, would reduce the blowout duration, and thereby limit the total amount of hydrocarbons released into the environment. By combining OPERAto, a dynamic tool for assessing environmental risks from offshore oil and gas activities, and an in-house blowout duration model, the authors have evaluated the use of capping as an environmental risk reduction measure. Uncertainties related to capping used as a solution for subsea blowouts are also discussed.

A detailed understanding of environmental risk factors for African swine fever (ASF) in wild boar will be not only essential for risk assessments but also for timely and spatially informed allocation of resources in order to manage wild boar-targeted ASF control measures efficiently. Here, we review currently known environmental risk factors that can influence the occurrence of ASF virus infection in wild boar when compared to disease occurrence in wild boar of a non-exposed reference scenario. Accordingly, the exposure of wild boar to environmental risk factors related to (1) climate, (2) land cover, (3) human activity, (4) wild boar and (5) ASF were evaluated. As key environmental risk factors in this review, increased ASF occurrence in wild boar was associated with seasonal patterns, forest coverage, presence of water, human presence, farming activities, wild boar density and ASF nearness. The review highlights inconsistencies in some of these risk factor associations with disease detection in space and time and may provide valuable insights for the investigation of ASF transmission dynamics. The examined risk information was applied to consider potential improvements of the ASF control strategy in wild boar regarding disease surveillance, hunting, wild boar carcass searches and ASF barrier implementation.

Environment And Health

An Environmental Impact Assessment (EIA) auditing was carried out at a sanitary landfill in Kuala Langat, Selangor, Malaysia. It was conducted to assess the environmental and health impact of the landfill. The study also includes an environmental risk index and life cycle analysis (LCA) approach to evaluate the facility. The auditing arrives with a conclusion that this facility might pose a hazard to the environment and health if no adequate control measures are taken consistently. Environmental auditing and LCA simulation could become an essential tool in the monitoring of urban planning and development.

Mining Areas

The district Sonbhadra, previously a part of Mirzapur district in Uttar Pradesh, India, was created as a separate district in 1991.Geologically the area consists of Vindhyan supergroup, Mahakoshal group and Dudhi granitoid complex.The district Sonbhadra has rich mineral resources and their potential. The area is known for production of cement grade Limestone and Dolomite; the other minerals are Clay, Calcite, Silimanite and base metals for more than last three decades. These mining areas show impacts on the environmental status of the district. In the present study, the different mining and environmental parameters have been considered for analysing the environmental impact assessment (EIA). A matrix method has been used to delineate the quantitative EIA in the area. Finally, the resulted assessment impact value index (-2861.76), shows significant impact on environment such as degradation of forest land, air contamination due to mining dust, water quality and related health aspect of the area. Thus, major environmental control measures should be taken for sustainable development of the study area such as improvement of mining equipments, proper dumping of the mining waste and large scale plantation.

Summary Graph

AbstractGround collapses over abandoned underground mines constitute a new environmental risk in the world. The high risk associated with subsurface voids, together with lack of knowledge of the geometric and geomechanical features of mining areas, makes abandoned underground mines one of the current challenges for countries with a long mining history. In this study, a stability analysis of Montevecchia marl mine is performed in order to validate a general approach that takes into account the poor local information and the variability of the input data. The collapse risk was evaluated through a numerical approach that, starting with some simplifying assumptions, is able to provide an overview of the collapse probability. The final results is an easy-accessible-transparent summary graph that shows the collapse probability. This approach may be useful for public administrators called upon to manage this environmental risk. The approach tries to simplify this complex problem in order to achieve a roughly risk assessment, but, since it relies on just a small amount of information, any final user should be aware that a comprehensive and detailed risk scenario can be generated only through more exhaustive investigations.

Aims: To evaluate the perception and control measures towards environmental risk in Obio Akpor Local government area (LGA) of Rivers State. Place and Duration of Study: The study was carried out at the Rivers State Waste Management Agency in Obio-Akpor LGA of Rivers State between January 2019 - March 2019. Methodology: The survey method was employed and the simple random techniques was adopted whilst 265 copies of the questionnaire were used to elicit information from the number of employee. Results: The findings revealed that that majority of the respondents under survey had a good knowledge of occupational health risk and are fully aware of the environmental health risk associated with waste dumping, As a Possible control measures it was revealed that the majority had the opinion that the provision of safety and health structure is the best preventive measures so as to eliminate health hazard among solid waste workers. Conclusion: RIWAMA should establish sanitary facilities where workers can wash after work to ensure effective personal hygiene is maintained and also provide them with Personal protective equipment.
