大气微生物与气象条件及大气污染物的灰色关联分析

根据大气微生物浓度、气象因子和大气污染理化因子的监测结果，应用灰色关联分析原理，分析研究大气微生物浓度与气象条件和大气污染物的关联程度，说明气象因子对各类微生物浓度的影响大于大气污染因子，特别是对耐高渗透压霉菌。     

我国内陆流域各类水体中天然放射性核素浓度

1985年～1989年由新疆、甘肃、青海、西藏、内蒙古、陕西、宁夏等省、自治区环境监测站(研究所)对内陆流域各类水体中U、Th、~(226)Ra、~(40)K浓度进行调查,由调查的29条内陆河、23个湖泊、15座水库、55处井泉和34个自来水的统计结果表明,流域内各水体中U和~(40)K浓度的平均值与同期调查的黄河水系同类水体的浓度相近,明显高于长江水系,与全国同类水体相比亦属偏高。Th和~(226)Ra的平均浓度与全国同类水体的浓度相近,甘、新内陆区浓度较低。调查发现,一些咸水湖、井水和自来水中U、~(226)Ra,或~(40)K浓度异常偏高。     

浅谈小型餐饮服务业排污申报登记

简述了小型餐饮服务业的特点，指出排污申报登记制度落实难、废水中各污染物排放量核定难及申报登记表设计欠合理是小型餐饮服务业在排污申报登记中存在的主要问题。提出，应加大宣传力度，进一步提高餐饮服务业业主以及广大公民的环保意识；制定较合理的排污量核算系数，修订申报内容；实行《排污申报登记注册证》制度，强化执法力度，以促进小型餐饮服务业全面实施排污申报登记制度。     

Obligations to animals are based on rights

Some feminist philosophers criticize the idea of human rights because, they allege, it encapsulates male bias; it is therefore misguided, in their view, to extend moral rights to non-human animals. I argue that the feminist criticism is misguided. Ideas are not biased in favour of men simply because they originate with men, nor are ideas themselves biased in favour of men because men have used them prejudicially. As for the position that women should abandon theories of rights and embrace an ethic that emphasizes care: women who made this choice would not so much liberate themselves from the patriarchy as they would conform to its representation of women as emotional, subjective and irrational. There is, then, no good reason to withhold ascribing rights to non-human animals, based on the criticisms of rights made by some feminists.Some of the material in the discussion of the feminist critique of rights originally appeared in my The Case for Animal Rights: A Decade's Passing inA Quarter Century of Value Inquiry: Presidential Addresses of the American Society of Value Inquiry, edited by Richard T. Hull, pp. 451–455. Amsterdam and Atlanta, GA: Rodopi, 1994.

Fractionation of Cu, Pb and Zn in certified reference soils SRM 2710 and SRM 2711 using the optimized BCR sequential extraction procedure

Sequential extraction of metals from solid media is a common analytical tool used in environmental and exploration geochemistry. A number of procedures exist, but without harmonization and standardization, meaningful comparisons are tenuous without baseline data. A newly developed, standardized sequential extraction procedure (optimized BCR) was applied to two contaminated certified reference soils from Montana, US (SRM 2710 and SRM 2711) for Cu, Pb and Zn. Four operationally defined fractions were isolated, acid extractable, reducible, oxidizable, and residual (by aqua regia). Fraction-specific concentrations, percentages and recoveries for Cu, Pb and Zn were used to explore differences between the optimized BCR procedure and three other sequential extraction schemes with published data for SRM 2710 and 2711 (i.e. Tessier scheme, Geological Survey of Canada scheme and the original BCR scheme). Results indicate significant differences between the four schemes, even for schemes that are closely associated (i.e. the original and optimized BCR schemes). Order-of-magnitude fraction-specific concentration differences were observed, especially for Pb in the reducible fraction. Differences between schemes are worrisome because trends varied between metals, between fractions and between reference soils. These data reinforce the need for increased adoption of standardized sequential extraction procedures and further examination of different solid media.

有机磷酸酯诱导迟发性神经毒性及其对神经毒性酯酶（NTE）活性影响的动态研究

以成年产卵来航母鸡为试验动物，研究了三甲基苯基磷酸酯（Ｔｒｉ－ｏ－ＣｒｅｓｙｌＰｈｏｓ－ｐｈａｔｅ，ＴＯＣＰ）诱导的迟发性神经毒性．试验发现，母鸡口服ＴＯＣＰ（７５０ｍｇ／ｋｇ）后，经过大约８－１０ｄ的潜伏期开始出现中毒症状，其表现为以步态失调为主要特征的运动障碍呈进行性加重，至第２１ｄ开始便发展为瘫痪，对鸡脑神经病损靶标酯酶（ＮｅｕｒｏｐａｔｈｙＴａｒｇｅｔＥｎｚｙｍｅ，ＮＴＥ）活性的测定表明，有机械诱导的迟发性神经毒性（Ｏｒｇａｎｏｐｈｏｓｐｈａｔｅ－ＩｎｄｕｃｅｄＤｅｌａｙｅｄＰｏｌｙｎｅｕｒｏｐａｔｈｙ，ＯＰＩＤＰ）与ＮＴＥ活性抑制之间的关系不平行，其毒性症状的轻重与ＮＴＥ活性被抑制的强弱也不呈正相关，很可能，在给药后２４ｈ，体内ＯＰＩＤＰ已被触发，此外，实验观察到给予ＴＯＣＰ后被试鸡的体重明显下降。
