查询词典 remediation

Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.

以相对修复年限为评价指标定义相对修复年限为0-10年的植物为"超富集植物"，10-50年的植物为"富集植物"。7在由不同废弃物按一定的比例混合配制的六种土地复垦基质上，系统地研究了几种植物对重金属镉的吸收和富集情况，结果表明，相对修复年限既适用于不同植物对同一种重金属元素的吸收能力的评价，又适用于同一植物对不同重金属元素的吸收能力的评价，是衡量重金属元素植物修复效果的理想指标。8从不同植物对同一基质重金属镉的吸收和富集能力看，不论是经过多年种植的基质，还是第一次种植的基质，小白菜和油菜都是相对理想的植物；而黑麦草、高羊茅和苜蓿的吸收效果并不理想。

Current studies involving in-situ remediation of Pb-polluted soils via phosphorus-compounds are reviewed in this paper.

In this study, three PAEs compounds, that is diethyl phthalate, di-n-butyl phthalate and bis(2-ethylhexyl) phthalate, were selected as objective compounds, and pot experiments of different plants (including maizes and forage plants) with different remediation measures in glasshouse were carried out and GC/MS analysis of PAEs were used to investigate the remediation effect of soils contaminated by PAEs by different plants and remediation measures.

本论文选取3种PAEs化合物（DEP、DBP和DEHP），以气相色谱/质谱联机检测技术，通过盆栽试验研究不同植物对PAEs化合物的降解差异，并在筛选对PAEs修复能力较强的植物的基础上，探讨其在不同条件下对PAEs污染土壤的植物修复效果，为PAEs污染土壤的植物修复提供理论依据和实用技术。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration. The Medaka embryo toxicity test had presented that while eggs were exposed to the soil extracts from fluoranthene and pyrene at high concentration (3mg PAHs/g soil), the embryo showed low hatch ratio、bleeding, high abnormal ratio and delayed mature period. The addition of composting materials for remediation study showed strong embryo toxicity to Medaka embryo at all test concentration.

青鱂鱼鱼卵试验部分，受单一与混合PAHs污染土壤之萃取物对青鱂鱼鱼卵孵化影响，当暴露在浓度3 mg PAHs /g soil时，及四环的Fluoranthene与Pyrene之下，皆有高未孵化率、高出血率、高畸形率及孵化天数的延迟现象产生；而在复育实验之土壤萃取物对青鱂鱼鱼卵孵化之影响，以添加酸性界面活性剂与中性界面活性剂实验组其鱼卵之未孵化率皆为零，与Microtox毒性测试结果有良好的关连；加入不同复育添加剂中，则以添加菜肥之实验组，对於青鱂鱼鱼卵孵化之影响为最大。
