From a literature-based assessment of the current knowledge about both the toxic or salutary properties of copper, this study focused on the determination, at 25 °C, of the interfacial properties of CuCl2, either alone or in mixture with carbofuran used, here, as a model of organics and/or pesticide. The interfaces under study were: i) the air/solution interface and ii) the silica/solution interface. The former is considered as a path for volatilization, whereas the latter permits a modelling of physical adsorption upon solids, which is the first and unavoidable step in any adsorption process. One should note that it can also mimic adsorption on some sandy soils. Coadsorption was clearly identified as implicated in an enhancement of the surface content of both solutes at both interfaces. However, at the two interfaces under study, the way the surface became structured led to opposite adsorption mechanisms for the organic compounds and the salt. A rough theory about ionic adsorption is also proposed. 相似文献

When an explosive detonates or a propellant or flare burns, consumption of the energetic filler should be complete but rarely is, especially in the presence of large amounts of non-combustible materials. Herein we examine three types of perchlorate-containing devices to estimate their potential as sources of contamination in their normal mode of functioning. Road flares, rocket propellants and ammonium nitrate (AN) emulsion explosives are potentially significant anthropogenic sources of perchlorate contamination. This laboratory evaluated perchlorate residue from burning of flares and propellants as well as detonations of ammonium nitrate emulsion explosives. Residual perchlorate in commercial products ranged from 0.094 mg perchlorate per gram material (flares) to 0.012 mg perchlorate per gram material (AN emulsion explosives). The rocket propellant formulations, prepared in this laboratory, generated 0.014 mg of perchlorate residue per gram of material. 相似文献

This review outlines nitrogen (N) responses in crop production and potential management decisions to ameliorate abiotic stresses for better crop production. N is a primary constituent of the nucleotides and proteins that are essential for life. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment. Therefore, increasing plant N use efficiency (NUE) is important for the development of sustainable agriculture. NUE has a key role in crop yield and can be enhanced by controlling loss of fertilizers by application of humic acid and natural polymers (hydrogels), having high water-holding capacity which can improve plant performance under field conditions. Abiotic stresses such as waterlogging, drought, heat, and salinity are the major limitations for successful crop production. Therefore, integrated management approaches such as addition of aminoethoxyvinylglycine (AVG), the film antitranspirant (di-1-p-menthene and pinolene) nutrients, hydrogels, and phytohormones may provide novel approaches to improve plant tolerance against abiotic stress-induced damage. Moreover, for plant breeders and molecular biologists, it is a challenge to develop cotton cultivars that can tolerate plant abiotic stresses while having high potential NUE for the future. 相似文献

Anthropogenic impacts on heavy metal concentrations in the coastal sediments of Dumai, Indonesia 总被引:2,自引:0,他引:2

Concentrations of Cd, Cu, Pb, Zn, Ni and Fe were determined in the surface sediments to investigate the distributions, concentrations and the pollution status of heavy metals in Dumai coastal waters. Sediment samples from 23 stations, representing 5 different site groups of eastern, central and western Dumai and southern and northern Rupat Island, were collected in May 2005. The results showed that heavy metal concentrations (in microg/g dry weight; Fe in %) were 0.88 (0.46-1.89); 6.08 (1.61-13.84); 32.34 (14.63-84.90); 53.89 (31.49-87.11); 11.48 (7.26-19.97) and 3.01 (2.10-3.92) for Cd, Cu, Pb, Zn, Ni and Fe, respectively. Generally, metal concentrations in the coastal sediments near Dumai city center (eastern and central Dumai) which have more anthropogenic activities were higher than those at other stations. Average concentration of Cd in the eastern Dumai was slightly higher than effective range low (ERL) but still below effective range medium (ERM) value established by Long et al. (Environmental Management 19(1):81-97, 1995; Environmental Toxicology Chemistry 17(4):714-727, 1997). All other metals were still below ERL and ERM. Calculated enrichment factor (EF), especially for Cd and Pb, and the Pollution load index (PLI) value in the eastern Dumai were also higher than other sites. Cd showed higher EF when compared to other metals. Geo-accumulation indices (I(geo)) in most of the stations (all site groups) were categorized as class 1 (unpolluted to moderately polluted environment) and only Cd in Cargo Port was in class 2 (moderately polluted). Heavy metal concentrations found in the present study were comparable to other regions of the world and based on the calculated indices it can be classified as unpolluted to moderately polluted coastal environment. 相似文献

Effect of Humic Acids and Fungal Inoculations on Cesium and Lead Concentrations in Lettuce Plants Grown in Contaminated Soils 下载免费PDF全文
A study was carried out to evaluate the effect of humic acid additives, applied either individually or in combination with Fusarium oxysporum fungi, on uptake and translocation of cesium and lead in cultivated Lettuce (Lactuca sativa) grown on Mostorud (clayey) and El‐Gabal El‐Asfar (sandy loam soil) soils in a complete randomized block experimental design. The selected soils from contaminated areas (Mostorud soil was irrigated with contaminated industrial water for more than 30 years and El‐Gabal EL‐Asfar soil was irrigated with sewage effluent for more than 50 years). The results indicated that the cesium and lead content was reduced by all treatments of humic acid application individually or when combined with Fusarium oxysporum inoculations, especially at 200 mmol/kg compared to a control and other treatments. On the other hand, retention of cesium and lead occurred in roots more than shoots. ©2016 Wiley Periodicals, Inc. 相似文献
