Due to the non-selective characteristics of oxidants, three aspects concerned for estimating ISCO oxidant dosage requirement for effective treatment of target contaminants must be considered: the stoichiometric amount of oxidant for destroying the contaminant, the oxidant demand to meet with the consumption by natural soil oxidizable matters and the amount resulting from oxidant self-decomposition. It should be noted that the oxidant consumed by the background organic and inorganic components of the soil aquifer matrix is known as soil oxidant demand of the treatment zone.

由於大多數(shù)氧化劑不具選擇性黑人A片特级又粗又大，因此若欲使目標(biāo)污染物達(dá)到良好的降解效率五月草视频，必須考量目標(biāo)污染物所需之氧化劑劑量激情文学综合区图片区小说区、氧化劑本身自我降解量18禁网站。，以及與土壤中其他可氧化物質(zhì)（oxidizable matter91色色视屏，OM）反應(yīng)之消耗量，此三者綜合才是真正現(xiàn)地應(yīng)用所需之氧化劑總量亚洲鲁在视频在线观看，而用以克服土壤中非目標(biāo)OM之氧化劑量稱為土壤氧化劑需求量（soil oxidant demandAAA亚洲无码高清，SOD）。

The degradation of PAHs at 0.03, 0.3, and 3 mg/g soil, either added singly or as mixtures, were evaluated for their evolved CO2 in Biometer flasks. The contaminated soil was later Soxhlet extracted with hexane. The extracts were evaporated, redissolved in dimethyl sulfoxide, and subjected for Microtox assay and Medaka embryo toxicity test. The evolved CO2 from singly PAHs addition was correlated with concentration gradient.

The soil nutrient is detected in five shrub trees, namely Periploca sepium, Sophora davidii, Syringa pekinensis, Ostryopsis davidiana, Caragana intermedia and comparative Bothriochloa ischaemum community. We have evaluated comprehensively on soil nutrient index during the process of shrub community form and analyzed the linear correlation of soil nutrient factors.

In an article first published in Foreign Affairs in 1993 and then expanded into a book, Huntington foresaw the shape of the post Cold War world. The war of ideologies would yield to a civilizational struggle of soil and blood. It would be the West versus the eight civilizations dividing the rest—Latin American, African, Islamic, Sinic, Hindu, Orthodox, Buddhist, and Japanese.

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.
