To evaluate the toxicity of the sludge, dredged from Victoria Port of Hong Kong , to marine benthonic animals lived in its pouring region, the toxicity test of the sludge to marine benthonic animals, including benthonic shellfish and crustacean, has been conducted.

为了评价香港维多利亚港疏浚淤泥对倾倒海区海洋底栖动物的影响，进行了两种底栖贝类和一种底栖甲壳类的生物毒性累积试验。结果表明，试验底栖贝类结蚶和缢蛏暴露在试验淤泥中240h和480h后，随暴露时间的延长，累积率增大。

However, the mutated isoform of UGT2B7 was a risk factor for developing bladder cancer in benzidine exposed Chinese workers.

然而，在中国联苯胺暴露个体中UGT2B7 C802T(H268Y)的突变了的多态性是决定暴露个体的膀胱癌易感性的一个风险因子。

Results showed that, within the test concentrations limits, total P450 content and SOD activity were very sensitive to the toxicity of Benzo pyrene. POD activity was elevated only when earthworms exposed to the maximum BaP concentration 10^(-2mgmL^(-1). CAT activity did not show any response to BaP exposure.

结果表明，在供试质量浓度范围内，蚯蚓体内P450含量和SOD活性与苯并芘污染胁迫存在明显的响应关系，POD活性在BaP的最大暴露质量浓度下10^(-2mgmL^(-1)被显著诱导，而CAT活性对BaP暴露无明显的指示作用。

Methods : We subjected C57BL/6J mice to CS (whole body exposure, 90 min/day) for various periods, and used laser capture microdissection to isolate bronchiolar epithelial cells for analysis of mRNA by quantitative reverse transcription-polymerase chain reaction.

研究方法：研究者将 C57BL/6J 小鼠分别在不同时间周期暴露于CS（全身暴露，90分钟/天），用激光捕获显微切割技术分离细支气管上皮细胞，然后用定量逆转录多聚酶链反应分析上皮细胞的mRNA。

The concentration of Cosmogenic nuclides is not only constrained by production rates and exposure time, and also closely related to surface erosion. Furthermore, the concentration is affected by geomagnetic intensity, shielding, chemical weathering, and sample geometry as well. These factors affecting Cosmogenic nuclide concentration should be calibrated when surface exposure age is calculated.

地表物质中宇宙成因核素浓度除了受到核素生成速率和地表物质的暴露时间制约外，还与地表侵蚀速率密切相关，此外，地磁场强度、遮蔽、化学风化及样品的几何位置等也会对核素浓度产生一定影响，在求算样品的地表暴露年代时，应对这些因素进行相应的校正。

The relationships among the targeted neurovascular structures were described and the difference between the median and paramedian infratentorial-supracerebellar approaches were analyzed. Results: The median infratcntorial-supracerebellar approaches provided direct exposure of the incisural space, although culmen represented a relative obstacle to expose of the quadrigeminat area.

结果：正中幕下小脑上入路直接暴露厂后切迹间隙，但山于小脑对视野的阻碍，限制了四叠体板下半部分的暴露；旁正中幕下小脑上入路视野范围集中在中切迹水平的脑干背外侧面区域，且可以观察到同侧的上、下丘。

The mean frequencies of disomic sperms for chromosome 1 and 18 in exposed group(0.088% 0.041%,and 0.087% 0.049%,respectively) were statistically increased over that of the control group(0.045% 0.024%,and 0.053% 0.028%),and the mean frequencies of nullisomic sperms for chromosome 1 and 18(0.11% 0.059%,0.075% 0.035%) in exposed group were statistically increased over that of control group too(0.048% 0.018%;0.045% 0.024%).

结构畸变测定结果：暴露组1号染色体的末端重复率、末端缺失率（分别为0.16% 0.037%，0.14% 0.053%）显著高于对照组数值(分别为0.082% 0.023%，0.069% 0.028%)；暴露组1号染色体着丝粒重复率及着丝粒缺失率(0.10% 0.035%，0.10% 0.041%)显著性高于对照组相应数值(分别为0.075% 0.023%，0.060% 0.029%)。

Therefore, a experimentent with three exposure types (early cleavage exposure, 0hpf; gastrula exposure, 8hpf and 0hpf exposure but stop after 8 hours, 8h stop) were designed to investigate the toxicity and bioaccumulation of bisphenol A in zebrafish embryo in different stages.

为研究胚胎在不同发育阶段对外源化合物的毒性敏感差异，以0hpf、8hpf和8h终止3种暴露方式进行染毒，探讨斑马鱼胚胎在不同暴露时段对双酚A毒性和生物蓄积特征。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
