RAINS-ASIA模型及上海市、浙江省的应用

ＲＡＩＮＳ是欧洲开发的关于酸雨污染综合分析的计算机模型。模型参数根据亚洲情况进行调整后，称为ＲＡＩＮＳ－ＡＳＩＡ。该模型能根据国家和地区的经济、行业、能耗状况，及污染控制技术，计算ＳＯ２的排放量分布和酸性污染物的输送沉积，结合各地临界负荷，建议控制对策。以上海市和浙江省为对象，采纳两地经济年鉴公布的数据，模型运行结果表明，其结论与其他研究成果相符，模型有良好的应用与开发前景。

森林降水化学的变化特征和机理

研究并比较了湖南酸雨区韶山小集水区林内降水的化学特征，结果表明，与大气降水相比，穿冠水和地表穿透水中的富集的离子浓度除了NO3^-和Na^ 外均明显增加，到达地表的降水离子增加倍数最高达34．3倍；离子总量最高倍数为8．1倍，乔木树冠层的离子富集作用大于灌木层。韶山的大气降水、穿冠水和地表穿透水的年均pH分别为4．61、5．54和5．85。持续大量的降水对森林上空的污染物有较高的清除效果。

Distributions, cycling and recovery of amino acids in estuarine waters and sediments

Acid hydrolysis of estuarine water samples for the determination of amino acids (AAs) was tested and found to be effective at high (250 μM) nitrate concentrations when the anti-oxidant, ascorbic acid, was added to the samples. Hydrolysable AA concentrations were then determined in surface sediments collected from low and high salinity regions of the Tamar Estuary (UK) during winter 2003 and 2004, and in overlying water when simulated resuspension of sediment particles was performed. Concentrations of AAs in sediment samples comprised <50% of particulate nitrogen, fitting the paradigm that most sedimentary nitrogen is preserved within an organic matrix. When sediment samples were resuspended in overlying water (salinity 17.5), the rapid, measured increase in dissolved AA concentrations almost equalled the reported nitrate concentration in the lower estuary, with the subsequent decrease in the total dissolved AA levels suggested that bacterial uptake was occurring. Our data concur with previous studies on nitrogen desorption from sediments and suggest that an understanding of organic nitrogen cycling will be an important aspect of future effective estuarine management.     

Decolorisation of Acid Blue 74 by ultraviolet/H<Subscript>2</Subscript>O<Subscript>2</Subscript>

The photodegradation of Acid blue 74 in aqueous solution employing a H₂O₂/ultraviolet system in a photochemical reactor was investigated. The kinetics of decolorization were studied by application of a kinetic model. The results show that the reaction of decolorization followed pseudo-first order kinetics. We demonstrate that there is an optimum H₂O₂ concentration, at which the rate of the decolorization reaction is maximum. Irradiation at 253.7 nm of the dye solution in the presence of H₂O₂ results in complete discoloration after ten minutes of treatment.
