双酚A的健康影响以及各国对其在塑料制品中的限量要求

Health Effects of Bisphenol A and Their Limits in Plastics Products Abroad

双酚A被广泛应用于塑料制品中,近年来的研究成果表明低剂量下双酚A对动物和人体会产生多方面的影响,包括生殖系统、神经系统、胚胎发育、免疫系统等,并与肥胖、糖尿病、癌症等的发病相关。2008年以来已有多个国家出台了限制使用双酚A的政策。该文就双酚A对机体健康的影响加以重点介绍,并概述了各国对塑料制品中双酚A的限量要求及禁用政策。

In recent years, the increasing water eutrophication and the frequent occurrence of water bloom has seriously affected human living environment, thus, it is of great significance making timely and accurately monitoring and warning for water bloom. The evolvement of the early-warning and prediction technologies of algal bloom at home and abroad were reviewed in this paper, including specific factors critical value prediction, math model based on hydrology and water quality parameters, and remote sensing （RS） technology, and the advantages and disadvantages of these three technologies were analyzed separately. Some new ideas of prediction on algal bloom which based on community diversity and microarray were brought forward after the comparative analyses of the three technologies mentioned above.
