Current practice and shortcomings of EIA in Lithuania

The paper provides an overview of EIA system applications and assesses its effectiveness in Lithuania. A combination of archival research and quantitative/qualitative analysis was used to identify the main shortcomings of the EIA process in Lithuania: subjectivity in forecasting environmental effects, insufficient consideration of alternatives, politicisation of the process and incompetence of authorities involved. The research revealed that a thorough knowledge of EIA procedures and legal requirements may be a solution to these problems, especially when the stages related to forecasting the effects and evaluating the results are strictly reserved for recognized experts. The work concludes on the suggestions to involve in EIA process relevant authorities and to increase the competence of EIA practitioners.     

Evaluating the use of Social Impact Assessment in the context of agricultural development projects in Iran

The utilisation of Social Impact Assessment (SIA) in Iran is analysed in terms of its policy context and its application in practice. Five case studies where SIA was employed in conjunction with Environmental Impact Assessments (EIA) for agricultural development projects are evaluated. In addition, the performance of the policy context is assessed. This research revealed that there are legal and institutional constraints to the effective functioning of SIA in Iran, and that there are deficiencies in the operating guidelines. There were serious problems associated with the way SIA was undertaken in all five case studies. Recommendations to improve the policy framework for the conduct of SIA are made. The recommendations advocate for a higher profile of SIA within legislation, for social issues to have greater emphasis in official guidelines for the conduct of EIA and SIA, and for a range of measures to increase the professionalism of SIA practice.     

郯城地区地下水化学特征及针对硝酸盐的健康风险评价

利用郯城地区100个地下水的水样监测数据,总结水化学特征,分析成因,并针对氮污染问题开展了硝酸盐健康风险评价.结果表明:区内地下水呈弱碱性,矿化度较低,总硬度为中等,水化学类型以HCO3-Ca型为主,但是氮污染严重.分析认为,地下水化学组成主要受岩石风化与人工施肥控制,碳酸盐岩和硅酸盐岩的风化溶解与氮肥施用是水化学现状...     

Legal aspects of pesticides and toxic substances testing requirements

Abstract

The United States Environmental Protection Agency administers several laws and progrms through which it reviews the hazard potential of pesticides and other toxic substances which may present a risk to human health or the environment. The Agency's ability to assess hazard as required by law depends in part on test data developed through testing standards in Agency regulations. In reviewing the Agency's actions in this regard, the courts emphasize the importance of reasoned regulatory decisions. The legal requirements to assess risk and provide reasoned decisions in this regard establish the legal importance of testing guidelines and test data, and indicate that sound test methodology is as important legally as it is scientifically.
