常见拟除虫菊酯(原药、商品)及助溶剂对水生生物毒性的比较

为了研究拟除虫菊酯对水环境的危害，为制订安全的水质标准提供理论依据，研究７种常见拟除虫菊酯对４种鱼类、水蚤和藻类的毒性，结果表明：拟除虫菊酯对所有试验生物均属剧毒，其中水蚤最为敏感，藻类较不敏感，而鱼类（除泥鳅）的敏感性相近．α－氰基和卤族元素会增加拟除是菊酯对水生生物的毒怀，由于发药商品中性含液剂二甲苯的毒性比试验中农药原药所用济剂丙酮的毒性高，因此农药商品中助溶剂的毒性应加以考虑

防城港二期围海工程后的潮流变化及溢流悬沙输移

用浅滩潮流模型预测防城港二期围海工程对港湾潮流的影响，用泥沙模型模拟溢流悬浮沙的输移范围，结果表明，二期工程后防城港潮流变化不大，溢流悬沙浓度大于１０ｍｇ／Ｌ的最大范围为２０００ｍ。     

Biomarkers in fluid inclusions of polymetallic deposit of Qixiashan, Nanjing

Conclusions Organic fluid involved in Pb-Zn mineralization in the polymetallic deposit of Qixiashan probably derives from bacteria and algae, and is similar to that of the mature crude oil system. Part of lead and zinc in fluids can be transported by organic complexes, while their precipitation is caused by organic reduction. Biomarkers in ores can indicate the source of organic matter in fluids, but organic matter in inclusions must be studied to ascertain organic metallogenesis because of the EOM difference between ores and inclusions. The host strata of Upper Carboniferous (C2) and Lower Permian (PI) in Qixiashan deposit are both oil-bearing in the region. Identification of organic fluid and its biomarkers in the deposit provides significant information for further studies on the relationship between ore deposits and oil pools in the region.     

Piezoelectric immunoassay of thyroidal triiodothyronine

A re-utilizable piezoelectric crystal (PC) immunosensor for thyroidal triiodothyronine (T3) has been developed. The crystal was coated with protein A and then reacted with T3 antibody. T3 could be detected in the range of 0.5×10⁻⁶ g/L to 10.0×10⁻⁶g/L by the, system. Crystal was regenerated by saturating with T3 and subsequent binding of a new anti-T3 antibody layer. The T3 assay could be repeated up to 5 times using each crystal. Supported by the National Natural Science Foundation of China Zha Hongying: born May, 1969, Ph. D.     

Experimental study of gold distribution in the algae-organic matter-fluid system

Conclusion Gold distribution and transformation in algae-organic matter-fluid system is very complicated. Gold is first concentrated in kerogen after algae died. With the increase of dissolved organic matter owing to the increase of temperature and pressure, part of gold simultaneously emigrates from kerogen to DOM. When DOM forms organic fluid and emigrates from the strata, gold is simultaneously carried away by organic fluid in acidic condition, but by water in alkali condition. When the auriferous fluid flows through carbonaceous strata, gold in fluid is unloaded by kerogen. Gold migration in the system, accompanied by the evolution of algae-organic matter-fluid, provides the basic information of biometallogenetic evolution of gold.
