查询词典 PAHs

However, the situation reversed in roots uptaking PAHs. With close lipid concentrations, leaves with pubescence or rough surface were found to have stronger capability in uptaking PAHs than the others, and the capability of the fibre was stronger than the taproot.

脂肪含量相近时，表面粗糙或具有细密绒毛的叶片富集PAHs的能力较强，须根系根吸收PAHs的能力强于直根系根。

The toxic benzo\pyrene equivalents of the 16 PAHs ranged from 4.61 to 164 μg·kg-1,99% of which was contributed by 7 carcinogenic PAHs.

土样中16 PAHs的毒性当量浓度介于4.61~164 μg·kg-1之间，7种致癌性PAHs对总TEQBaP的贡献达99%。

Concentration and distribution characteristics of PAHs in soil between a Cinnamomum camphora stand and a bare land were studied,and PAHs concentration levels in two kinds of soil were evaluated.

研究樟树林地和无林地土壤中PAHs的含量和分布特征，并对两种土地类型土壤中的PAHs含量水平进行评价。

The contents of fluoranthene, phenanthrene and pyrene, three species of carcinogenic PAHs, accounted for 42% of the total content of PAHs, suggesting potential ecological risk from the PAHs in this area.

结果表明，在该研究区域内共检测出10种PAHs，总残留量范围为30.6～740.8 μg·kg-1，属轻微污染水平；但具有致癌作用的组分Fla、Chr和Baa含量约占总量的42％，说明该区域农田土壤存在一定的生态风险。

The studies indicate that the abundance of Fluoranthene, Phenanthrene and Pyrene were highly correlated with the total PAHs concentrations with correlation coefficients between 0.625 to 0.999 (α=0.05), suggesting the abundance of these three compounds might be used as good indicators for the total abundance of the PAHs in the soil around the power plant.

PAHs组分中含量相对较高的Fla、Phe和Pyr 3种化合物与各组分及总量间显著相关，Pearson相关系数在0.625～0.999（α=0.05）；可以认为，Fla、Phe和Pyr是研究区燃煤电厂附近农田土壤中PAHs的特征性化合物类型。

Statistics analysis and some diagnostic ratios were used for source identification and the contribution rates of main sources were also calculated. Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% and 64.93% and 14.11% respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion.

结果表明，不完全燃烧来源和石油类产品泄漏来源的贡献率分别为70.97%、11.38%和64.93%、14.11%；上海市中心城区地表灰尘中PAHs主要来源于各类矿物燃料的不完全燃烧，而且主要来源于当地污染源。

Source identification results showed that PAHs in surface sediments along the Yangtze estuary mainly came from incomplete combustion while PAHs in surface sediments from the Chongming island were mostly petrogenic PAHs.

来源辨析结果表明边滩表层沉积物PAHs主要来源于不完全燃烧，崇明低潮滩显示出较强的石油类产品泄漏来源的特征。

Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% and 64.93% and 14.11% respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion. In addition, local pollution sources were the main sources.

The results of research on community structure through the response of microbes in mangrove swamp under PAHs stress revealed that different changes of microbial community structure had occurred in different concentrations of Phe, Pyr, Flu, Bap and M-PAHs.

不同浓度的PAHs对红树林沉积物中的微生物群落结构的影响不同，较高浓度的PAHs对微生物群落结构的影响也较大，同时在高浓度的PAHs胁迫下，微生物群落结构发生改变的响应时间也较短。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
