OBJECTIVE: To study the neurotoxicity of BaP and its effects on expression of two heat stress proteins HSP70 and HSP90β in brain tissue of mice.

目的：研究苯并芘对小鼠的神经毒性及对脑组织中两种热应激蛋白70，90β表达的影响。

There was, however, no apparent change in EROD activity. The result suggested the important effect of intoxication of BaP on fish.

这说明苯并芘致毒对鱼体正常生命活动产生了重大影响，并具有潜在的致癌性。

The recoveries of seawater and sediment are :naphthalene 73. 0% and 75. 3%, phenanthrene79. 2%and78. 0%, fluoranthene 88. 1% and 80. 7%, pyrene 73. 8% and 70. 2%, chrysene 77. 6% and 72. 8%, benzofluoranthene 87. 6% and 83.6%, benzo pyrene 120. 3% and 110. 0%, respectively.

通过对7种多环芳烃标准样品的高效液相色谱法的定性、定量分析，结果表明，该方法可有效分离PAHs，回收率较高，海水和沉积物中的回收率分别为：萘73.0％和75.3％，菲79.2％和78.0％，荧蒽88.1％和80.7％，芘73.8％和70.2％，屈77.6％和72.8％，苯并荧蒽87.6％和83.6％，苯并芘120.3％和110.0％。

In the oil-generation window fluoranthene/pyrene reduced with the rising of maturity, and so did benzofluoranthene /benzopyrene in the mature to highly mature stages.

在成熟—高成熟阶段，苯并萤蒽/苯并芘比值也基本随熟度增加而降低。

Fifty-seven kinds of polycyclic aromatic hydrocarbon were detected by qualitative method,and sixteen kinds of those were mensurated by quantitative method.The results suggested that the average concentration of chry was the highest,21.83 ng/m3;the average concentration of fluoranthene was the second highest, 21.14 ng/m3; the mass c...

并对16种多环芳烃定量测定，结果表明：以屈艹为最高，平均值为21.83ng/m3；荧蒽次之，平均值为21.14ng/m3；苯并芘的质量浓度为14.52ng/m3，不满足GB3095-96中的质量浓度限值。2001～2003年检测结果对比表明，部分监测点空气中多环芳烃的浓度有下降的趋势。

Based on Fluoranthene/Pyrene and Pyrene/Benzopyrene ratios, the main source of PAHs was identified from petroleum industry at Jinzhou Bay, petrolic combustion turned into the source in Qinhuangdao and part of Liaodong Bay, and coal-burning was primary in the other areas.

荧蒽/芘和芘/苯并芘两个比值参数显示锦州湾近岸沉积物的PAHs主要源于石油工业，秦皇岛近岸和莱州湾部分站点主要来自燃油产物，而其它海区的大部分站点则属于燃煤型来源。

A study on HPLC analysis of benzopyrene in grain;2. Induction of EROD activity was investigated by an in vitro assay based on benzopyrene and hexa chlorobenzene .

用7-乙氧基异叻唑酮-脱乙基酶检测的方法，研究了苯并芘和六氯苯对日本青鳉肝脏EROD酶的比活力的影响。

The cause of high incidence rate of malign tumor in the front line workers in smithing workshop is closely related to the BaP content in workshop.

结论锻压车间生产一线职工肿瘤高发原因与生产环境空气中苯并芘含量关系密切，应通过改革热处理方法，彻底消除苯并芘对人体的危害，以保障生产一线职工健康。

Tween 80 at supraCMC resulted in reduced PAHs concentrations in wheat root and enhanced phenanthrene and pyrene concentrations in wheat stem and leaf.

在培养40天后，CMC以上Tween 80使小麦根中菲、芘和苯并芘含量下降，却促进了小麦茎叶中菲和芘的含量。
