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。

Data analysis shows that the total amount of PAHs in the sediments of north Taihu Lake is obviously higher than that at the central and south Taihu Lake, and that there is a little difference between the contents of PAHs of high molecular weight and low molecular weight, while the ratio of PAHs varies in different sections of the lake. Through the statistical analysis of the ratio of fluoranthene to pyrene, it is concluded that PAHs mainly come from oil burning with part of them from coal and wood burning.

分析结果表明，太湖北部的多环芳烃总量明显高于中部和南部，低分子量多环芳烃与高分子量多环芳烃的含量差别不大，但在地域上比例有所变化；根据荧蒽/芘的比值统计，多环芳烃主要来源于石油燃烧，部分为煤和木材的燃烧形成。

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。

The results show that ∑ PAH16 contents in source separation household bio-organic waste and composting production is 2,19 and 1.96 mg/kg DM, and the contents of naphthalene, fluorene, phenanthrene, fluoranthene are relatively higher than others.

结果表明，源分类家庭生物有机垃圾及其堆肥产品中∑PAH16化合物含量分别为2.19和1.96mg/kg，其中萘、芴、菲、荧蒽含量相对较高，占总量的79.76%和81.76%，这4种有机物的苯环在2-3之间，属于易降解非致癌物质，在农田施用中易被降解；在生物垃圾堆肥过程中∑PAH16的生物降解率为25.88%，堆肥后产品PAHs含量符合农田使用标准。

The PAHs in sediment core were mainly composed of phenanthrene and fluorene. The concentrations of phenanthrene and fluorene in sediment core were 236.1-417.9 ng/g and 91-130.8 ng/g,respectively. Both of them accounted for 47.2%-58.1% of the ∑PAH16 in sediments.

沉积物中多环芳烃的组成以3环的菲和芴为主，它们的含量分别为236.1～417.9 ng/g和91～130.8 ng/g，二者共占沉积物中多环芳烃总量（∑PAH16）的47.2%～58.1%。

It is defined as the strength figure above which 95 % of the population of all possible strength measurements of the concrete in question may be expected to lie (95 % fractile).

对于强度数值超过混凝土所有可能强度测量总量的95%，则数据可能是错误的（95%分位点）。

The results showed that seed rain continued about two months with an average of 12.44 seeds m-2 and peaked at late November to early December. There's significant difference among the proportions of perfect, worm-eaten, abortive, decayed and germinated seeds in the process of seed rain, in which the proportion of the worm-eaten was 19.44 times as great as the geminated.

结果表明，福建青冈种子雨持续2个月，其高峰期在11月下旬～12月上旬，总量为12.44 个 m-2，在种子散布过程中完好种子、虫蛀种子、败育种子、霉烂种子和萌发种子的比例差异明显，其中虫蛀种子是萌发种子的19.44倍。
