| 1 | Environmental behaviors of phoxim with two formulations in bamboo forest under soil surface mulching显示文摘Phoxim(emulsifiable concentrate(EC) and granules(G)) has been widely used in bamboo forests. The persistence and magnitude of phoxim residues in the crop and soil must be investigated to ensure human and environmental safety. The environmental behaviors of the two formulations were investigated in a bamboo forest under soil surface mulching conditions(CP) and non-covered cultivation conditions(NCP). The half-lives of phoxim in soil under the two conditions in soil were 4.1–6.2 days(EC) and 31.5–49.5 days(G),respectively. Phoxim in EC could be leached from the topsoil into the subsoil. A minimized leaching effect was observed for G under NCP. Inversely, an enhanced leaching effect was observed for G under CP. The G formulation resulted in more parent compound(in bamboo shoots) and metabolite(in soil) residues of phoxim than in the case of EC, especially under CP conditions. In addition, the intensity and duration of the formulation effect on soil p H adjustment from G were more obvious than that from EC. Results showed that the environmental behaviors(distribution, degradation, residue) of phoxim in the bamboo forest were significantly influenced by the type of formulation. The prolongation effect from phoxim G might cause persistence and long-term environmental risk. However,bamboo shoot consumption could be considered relatively safe after applying the recommended dose of the two phoxim formulations. | Yihua Liu Zhanglin Ni Runhong Mo Danyu Shen Donglian Zhong Fubin Tang | 2015 | Journal of Environmental Sciences2015，27，9： | 2 |

| 3 | The Biomarker Changes of a Heavy Fuel Oil After Different Weathering Times显示文摘This paper presents the experimental results of composition changes of heavy fuel oil by simulating weathering in static seawater under natural environmental conditions. The results indicate: n-C10 to n-C15 were lost gradually in 24 weeks and the relative abundance of alkanes with long chains (>n-C19) increased markedly. The aromatic compounds with less than two rings (except C4N) were completely lost in 24 weeks and CnP and CnD became the main aromatics in the heavy fuel oil after 24 weeks. The ratios of n- C17/ Pristane (Pr) and n-C18/ Phytane (Ph) were suitable for identifying lightly weathered (3 weeks) heavy fuel oil. The ratios of n-C17/ n-C18 and Pr/Ph were suitable for identifying moderately weathered heavy fuel oil (12 weeks); the ratios of C2D/C2P and C3D/C3P did not change significantly in 24 weeks and were more suitable for identifying moderately weathered heavy fuel oil (24 weeks). | MA Qimin NI Zhanglin YU Zhigang | 2009 | Journal of Ocean University of China2009，8，1： | 0 |
| 4 | The phytochemical components of walnuts and their application for geographical origin based on chemical markers显示文摘Place of origin has an important influence on walnut quality and commercial value,which results in the requirement of rapid geographical traceability method.Thus,a method for geographical origin identification of walnuts on the basis of nutritional quality of walnuts from China was conducted.The concentrations of 43 phytochemical components were analyzed in walnut samples from five different walnut-producing regions of China.Based on 14 chemical markers selected by the Random Forest method from these phytochemical components,a new discriminant model for geographical origin was built,with the corresponding correct classification rate of 99.3%.In addition,the quantitative quality differences of walnuts from five regions were analyzed,with values of 0.17–1.43.Moreover,the top three chemical markers for the geographical origin discriminant analysis were Mo,V,and stearic acid,with contribution rates of 26.8%,18.9%,and 10.9%,respectively.This study provides a potentially viable method for application in food authentication. | Runhong Mo Yuewen Zheng Zhanglin Ni Danyu Shen Yihua Liu | 2022 | Food Quality and Safety2022，6，4： | 0 |
| 5 | Radial growth and non-structural carbohydrate partitioning response to resin tapping of slash pine(Pinus elliottii Engelm.var.elliottii)显示文摘Slash pine(Pinus elliottii Engelm.var.elliottii)is a resin-producing species grown worldwide for significant economic benefits for wood production.Resin tapping cre-ates a carbon sink at the expense of carbon allocation for growth and consequently,wood production may be reduced.Non-structural carbohydrates comprising starch and sugars stored in plant organs,may serve as intermediate pools between assimilation and utilisation.However,the effect of resin tapping between tree growth and non-structural carbo-hydrates is not well understood.This study investigated(1)the effects of resin tapping on radial growth,(2)the effects of resin tapping on non-structural carbohydrate pools in different compartments,and(3)the feasibility of resin pro-duction without disruption of tree growth.Twenty one-year-old slash pines were subjected to resin tapping over two suc-cessive years.Non-structural carbohydrate concentrations in needles,branches,stem phloem,and roots of tapped and untapped trees in summer and winter were determined after the second year of resin harvest.The results showed that tapping had no significant effects on annual increments.Starch was the dominant non-structural carbohydrate frac-tion,regardless of tissues and season,and constituted up to 99%of the total non-structural carbohydrates in the phloem and roots.Glucose and fructose were the dominant sugars;sucrose was negligible.Compared with the controls,tapped trees showed 26%lower non-structural carbohydrate concen-tration in the phloem above the tapping wound in summer,which was attributable to the decreased abundance of starch,glucose,fructose,and sucrose.In winter,the altered non-structural carbohydrate profiles in the phloem above the tap-ping wounding were minimised as a result of recovery of the sugar concentrations.In contrast to free sugars,which accu-mulated substantially in needles and branches during winter,starch was enriched in the phloem,roots,and current-year needles.The results provide evidence for a localised effect of resin tapping,and highlight the observation that resin extrac-tion does not always cause a sacrifice in wood growth under a moderate resin-tapping intensity in slash pine plantations. | Baoguo Du Qifu Luan Zhanglin Ni Honggang Sun Jingmin Jiang | 2022 | Journal of Forestry Research2022，33，2： | 0 |
