Based on the regulatory monitoring data of chlorpyrifos in vegetables sampled at random from markets and production bases in Beijing, and the consumption data of vegetables and body weight of different population collected in the China nationwide food consumption survey, the chronic dietary risk for children (7 years of age) and adult (30 years of age) populations were evaluated. In order to make the evaluation results conform to the reality, percentcroptreated (PCT) data were used. The result showed that the daily exposure of chlorpyrifos from vegetables for children is greater than that of adult group. The boy figure is about double to that of man；and girls is 1.78 to that of woman. Girls are the most sensitive population. The chronic assessment risk of adult man is acceptable. The rest populations are potentially risky. Great concern should be paid on them, especially children who takes the highest risky. The conclusion of risk assessment by percent (POR) was consistent with that by margin of exposure (MOE). It is feasible to use percentcroptreated data in risk evaluation. In order to reduce the residues of chlorpyrifos in vegetables, improving measures and surrogate pesticides should be taken in the course of vegetable production.

The genes associated with nitrogen fixation are often grouped in one or several contiguous units of the diazotrophic genome, which are the genetic basis of biological nitrogen fixation. Among them there are nitrogenase structural genes nifHDK, and many additional genes involved in electron transport and FeMocofactor biosynthesis and assembly. This paper conducted simple comparative analysis on the relationship between organization and evolution of nitrogenfixation gene clusters. Through comparing the nitrogenfixation gene clusters in all sequenced diazotrophs, we found that there were at least 6 conservative genes: nifH, nifD, nifK, nifE, nifN, and nifB, and all of them were essential for nitrogen fixation in characterized systems. Although there are some differences in their structures and organizing patterns by different diazotrophs. These nitrogenfixation gene clusters are structurally, mechanistically, and phylogenetically closely related. Meanwhile, the paper also prospected directions for studying nitrogenfixation genes. It aimed to provide theoretical basis for further studying the mechanism of biological nitrogen fixation and understanding the evolution of microbial nitrogen fixation.
