经济与环境协调与可持续发展的机制分析

人类社会经济飞速发展的同时带来了环境的持续恶化。经济发展与环境保护之间存在一种博弈的两难困境,人类必须制定一定的规则和机制来改变与脱离这种困境。推动全球绿色贸易是走出这种困境的一条可操作的途径,推动世界绿色贸易、提高环境保护技术整体能力是改变博弈结构的关键。可持续发展的概念的产生是对经济发展与环境保护的一种协调。另外推动环境正义的理念也是促使经济发展与环境保护之间合作的一种人文途径。     

镇江市大气环境承载力研究

根据前人对大气环境容量和环境承载力计算的对比分析,计算2012年镇江市的大气环境容量和大气环境承载力指数,通过对该市的气象条件和地理位置的分析,选取SO_2、NO_x和PM_(10)这3种主要大气污染物,并分析其环境承载状况。结果表明:句容市、丹阳市、杨中市处于高承载的状态,临界超载、严重超载和超载的3个区分别是润州区、京口区和镇江新区,针对这3个区提出相应改进措施。     

珠江口水环境中多溴联苯醚生态风险分析

以多溴联苯醚(PBDEs)作为研究对象,对珠江口水环境中多溴联苯醚进行了生态风险问题形成、生态风险分析及生态风险表征。研究结果表明,珠江口水环境中多溴联苯醚的生态风险主要来自五溴联苯醚,其在水相和沉积物相中的计算结果分别为0.000057和0.0073,目前珠江口水环境中多溴联苯醚的生态风险水平较低,暂无生态风险。

Research progress on distribution,sources, identification,toxicity, and biodegradation of microplastics in the ocean,freshwater, and soil environment

• Microplastics are widely found in both aquatic and terrestrial environments. • Cleaning products and discarded plastic waste are primary sources of microplastics. • Microplastics have apparent toxic effects on the growth of fish and soil plants. • Multiple strains of biodegradable microplastics have been isolated. Microplastics (MPs) are distributed in the oceans, freshwater, and soil environment and have become major pollutants. MPs are generally referred to as plastic particles less than 5 mm in diameter. They consist of primary microplastics synthesized in microscopic size manufactured production and secondary microplastics generated by physical and environmental degradation. Plastic particles are long-lived pollutants that are highly resistant to environmental degradation. In this review, the distribution and possible sources of MPs in aquatic and terrestrial environments are described. Moreover, the adverse effects of MPs on natural creatures due to ingestion have been discussed. We also have summarized identification methods based on MPs particle size and chemical bond. To control the pollution of MPs, the biodegradation of MPs under the action of different microbes has also been reviewed in this work. This review will contribute to a better understanding of MPs pollution in the environment, as well as their identification, toxicity, and biodegradation in the ocean, freshwater, and soil, and the assessment and control of microplastics exposure.     

应用地质累积指数评价攀枝花地区土壤重金属污染

应用地质累积指数对攀枝花地区昔格达组粘土中重金属污染进行了评价研究。结果表明，各重金属元素污染较严重的地区分布在宝顶煤矿、太平煤矿、攀钢冶钢厂、攀钢矿山、尾矿坝等工矿区，污染较轻微的地区分布在红格、新九等农业区。各元素的污染程度上看，该区As和Cu污染较重，Cd,Pb,Zn次之，而Cr污染最轻微。
