BACKGROUND:The fungicide of benomyl, a benzimidazole group, has been commonly used for pesticides against fungal diseases in the world. However, benomyl is rapidly hydrolyzed in the environment after using to control plant diseases and has adverse effects by generating carbendazim, which is toxic to plants, humans, and the environment. METHODS AND RESULTS: In this study, the decomposition effect of carbendazim, a degradation product of benomyl was conducted in pot and field after making a pro-totype of benomyl-degrading microbial agent (BDMA). We found that the carbendazim-degrading microbial agent (CDMA) (10 5 , 10 6 , and 10 7 cfu/g soil) decomposed carbendazim by 50% or more in all the treatments, compared to the untreated control in the pot tests after four weeks. The effect of 100% decomposition of carbendazim was observed at 7 days after treatment, when the prototype of BDMA was apllied at 10-folds dilution in the field. The decomposition effect at more than 60% and plant growth promoting effect were observed after 7 days of the treatment, compared with the untreated group in the second field experiment,treated with commercially available concentrations of 500-folds and 1,000-folds. CONCLUSION(S): These results might represent that the BDMA would decompose carbendazim effectively, a de-

Pesticide Pollution in Agricultural Soils and Sustainable Remediation Methods: a Review

An increasing number of pesticides have been used in agriculture for protecting the crops from pests, weeds, and diseases but as much as 80 to 90% of applied pesticides hit non-target vegetation and stay as pesticide residue in the environment which is potentially a grave risk to the agricultural ecosystem. This review gives an overview of the pollution in agricultural soils by pesticides, and the remediation techniques for pesticide-contaminated soils. Currently, the remediation techniques involve physical, chemical, and biological remediation as well as combined ways for the removal of contaminants. The microbial functions in rhizosphere including gene analysis tools are fields in remediation of pesticide-contaminated soil which has generated a lot of interest lately. However, most of those studies were done in greenhouses; more research work should be done in the field conditions for proper evaluation of the efficiency of the proposed techniques. Long-term monitoring and evaluation of in situ remediation techniques should also be done in order to assess their long-term sustainability and practical applications in the field.

“…10−12 VOCs may vaporize or spill during the course of remediation efforts, which can have a significant impact on both human health and the environment through air, soil, and water pollution. 13 Indoor VOC emissions from common sources such as sealants, paints, varnishes, cleaning products, and adhesives are also prevalent. 5 Outdoor emissions arise from industrial processes as well as the burning of a variety of fuels such as gasoline, wood, coal, and natural gas.…”

Strategies for the synthesis of a new class of porous and nonporous biodegradable microparticles (MPs) based on poly(d,l-lactic acid)–poly(ethylene glycol)–COOH (PDLLA–PEG–COOH) or poly(d,l-lactide-co-glycolide) (PLGA) copolymers have been investigated. Further, these MPs were coated with polyethylenimine (PEI) in order to compare the performance of the naked and PEI-capped MPs for the gas phase capture of model aldehyde volatile organic compounds (VOCs), hexanal and octanal. The removal efficiencies of the different MP formulations ranged from 50% reduction to 97% reduction of VOC vapors. By coupling the intrinsic gas adsorption properties of the parent, naked MPs with the potential for covalent capture by means of the PEI surface coating, we have generated new materials exhibiting a dual modality for VOC capture. These materials represent a new matrix for the remediation of VOCs based on renewable, sustainable polymers.
