提升应对突发性环境污染事故处置能力的思考

从应对突发性环境污染事故出发，通过案例分析阐述了如何开展环境污染事故的事前预防、现场应对和善后处理工作，提出构建科学、快速、高效的应急处置体系，提升应对突发性环境污染事故处置能力的方法。  

海洋环境中的三丁基锡污染

介绍了三丁基锡的性质，从化学分析、环境水平、毒性和人体接触等方面回顾了海洋环境中三丁基锡的研究进展。指出从食物中摄取是人类接触三丁基锡化合物的主要途径，提出对实验毒性、饮食摄入、人类健康潜在影响开展调查，以及发展新的消除三丁基锡的技术很有必要。  

Tree-ring analysis for the assessment of anthropogenic changes and trends

Investigation of Pine (Pinus sylvestris L.)annual radial increment (width of annual tree rings) was carriedout in the surroundings of one of the largest pollution sources inLithuania – Jonava Nitrogen Fertilizers Plant. The main objectiveof investigation was to analyse different sides of anthropogenictransformations of tree-ring series in the polluted environment:changes in tree growth intensity; variance changes in tree-ringseries; changes in the relations with natural external factors.Three different periods of tree reaction to the environmentalpollution were singled out – fertilization period, depressionperiod and recovery period since annual emissions were essentiallyreduced. The variance of tree-ring series has increased severaltimes in the polluted environment. Reaction of trees to the impactof climatic factors (temperature, precipitation) has changedsignificantly in the polluted environment and their sensitivity hasalso increased.
