摘 要:指出水产品代谢物的排出及没有被水产品利用的残饵是造成渔业养殖中水环境污染的重要原因之一。针对渔业污染物的生成情况 ,提出了渔业污染物排放总量的 3种核定方法 :实测法、物料平衡法。The discharge of metabolite of aquatic product and the residual food which were not eaten by aquatic product were the important reasons of water pollution in fishery. Three kinds of methods to determine the total quantity fishery pollutant discharge, as the actual determination, material balance and empirical factor,were suggested. Key words: Fishery; Pollutant; Total quantity determination14, China; 2. College of Pharmacy, Yanbian University, Yanji 133002, China)Abstract: Bidentate substrates of imide functionalized α,β unsaturated ketones, a new type of chelating dienophile and 1,3 diene, are designed and synthesized. Some new compounds, such as 1 succinimide 3 phenyl acrylicone, 1 succinimide 3 (m nitrophenyl) acrylicone, 1 phthalimide 3 phenyl acrylicone and 1 phthalimide 3 (m nitrophenyl) acrylicone, are prepared by the reaction of cinnamoyl chloride with corresponding o phthalimide or succinimide respectively. The Diels Alder reaction activity of the imide functionalized α,β unsaturated ketones with cyclopentadiene or isoprene is investigated. The structure of products obtained by the reaction is confirmed by elementary analysis, IR and 1H NMR.
