...This experiment was carried out to investigate the residue patterns of two insecticides, indoxcarb and thiamethoxam, commonly used for Chinese cabbage, under greenhouse conditions. The pesticides were sprayed onto Chinese cabbage at the recommended dose and double of the recommended dose 10 days before the prearranged harvest and then sampling was done at 0.17, 1, 2, 3, 4, 5, 6, 8, 10, and 12....

...Dicamba (3,6-dichloro-2-methoxybenzoic acid) is used to control for pre and post-emergence of annual and perennial broad-leaf weeds. It is very soluble in water and highly mobile, acidic herbicide. So it is easily moved and detected in groundwater. Zerovalent iron (ZVI) has been used for the reductive degradation of certain compounds through amination of nitro-substituted compounds and....

...This study was carried out to assess the antidermatophytic potential of the ethyl acetate (EtOAc) extract of the marine isolate of Aspergillus sp. The fungus was isolated by serial dilution, and was identified Aspergillus sp. The EtOAc extract of the fungus was examined to evaluate the antidermatophytic efficacy against the fungal pathogens infecting human skin using the disc diffusion and MIC....

...Phosphorus transfer from agricultural soils to surface waters is an important environmental issue. Fly ash and phospho-gypsum which are industrial by-product were investigated as a means of reducing dissolved phosphorus in arable soil. To determine the optimum mixing ratio of fly ash (FA) and phospho-gypsum (PG) for reducing dissolved reactive P (DRP) in soil, various mixture ratio of FA and PG....

...Current soil remediation principles for toxic metals have some limitations even though they vary with different technologies. An alternative technology that transforms hazardous substances into nonhazardous ones would be environmentally beneficial. Objective of this research was to assess optimum conditions for Cr(VI) reduction in soils as influenced by ZVI (Zero-Valent Iron), organic matter and....

...A greenhouse experiment was conducted to investigate the role of the arbuscular mycorrhizal (AM) fungus, Glomus mosseae (BEG 107) in enhancing growth and arsenic (As) and phosphorus (P) uptake of white clover (Trifolium repens) and evening primrose (Oenothera odorata) in soil collected from a gold mine having concentrations of 381.6 mg total As kg-1 and 20.5 mg available As kg-1. Trifolium repens....

...The study was carried out to estimate runoff loads of heavy metals in the valley watershed at the middle of South Korea, during farming season. There were no other pollution sources except agricultural activity. From 27 April 2006 to 31 October 2007, water samples were collected using two methods. The first method was regular sampling wherein water samples were taken every two weeks; and the....
