Pesticides in stormwater runoff−A mini review

Cheng Chen, Wenshan Guo, Huu Hao Ngo

《环境科学与工程前沿（英文）》 2019年 第13卷 第5期 doi: 10.1007/s11783-019-1150-3

摘要： • The sources and pathways of pesticides into stormwater runoff were diverse. • Factors affecting pesticides in stormwater runoff were critically reviewed. • Pesticides mitigation strategies were included in this review. • The current knowledge gap of the pesticides in stormwater runoff was identified. Recently, scientific interest has grown in harvesting and treating stormwater for potable water use, in order to combat the serious global water scarcity issue. In this context, pesticides have been identified as the key knowledge gap as far as reusing stormwater is concerned. This paper reviewed the presence of pesticides in stormwater runoff in both rural and urban areas. Specifically, the sources of pesticide contamination and possible pathways were investigated in this review. Influential factors affecting pesticides in stormwater runoff were critically identified as: 1) characteristics of precipitation, 2) properties of pesticide, 3) patterns of pesticides use, and 4) properties of application surface. The available pesticide mitigation strategies including best management practice (BMP), low impact development (LID), green infrastructure (GI) and sponge city (SC) were also included in this paper. In the future, large-scale multi-catchment studies that directly evaluate pesticide concentrations in both urban and rural stormwater runoff will be of great importance for the development of effective pesticides treatment approaches and stormwater harvesting strategies.

In situ enhanced bioremediation of dichlorvos by a phyllosphere

Jiying NING, Gang GANG, Zhihui BAI, Qing HU, Hongyan QI, Anzhou MA, Xuliang ZHUAN, Guoqiang ZHUANG

《环境科学与工程前沿（英文）》 2012年 第6卷 第2期   页码 231-237 doi: 10.1007/s11783-011-0316-4

摘要： A bacterium capable of degrading dichlorvos was isolated from the rape phyllosphere and designated YD4. The strain was identified as sp., based on its phenotypic features and 16S rRNA gene sequence. Strain YD4 was able to utilize dichlorvos as the sole source of phosphorus. enhanced bioremediation of dichlorvos by YD4 was hereafter studied. Chlorpyrifos and phoxim could also be degraded by this strain as the sole phosphorus source. A higher degradation rate of dichlorvos was observed after spraying YD4 onto the surface of rape leaves when compared to the sterilized-YD4 and water-treated samples. The results indicated that pesticide-degrading epiphytic bacterium could become a new way for phyllosphere bioremediation where the hostile niche is unsuitable for other pesticide-degrading bacteria isolated from soil and water.

Dechlorination of dichlorodiphenyltrichloroethane (DDT) by Fe/Pd bimetallic nanoparticles: Comparison with nZVI, degradation mechanism, and pathways

Kubra Ulucan-Altuntas, Eyup Debik

《环境科学与工程前沿（英文）》 2020年 第14卷 第1期 doi: 10.1007/s11783-019-1196-2

摘要： DDT undergoes dechlorination via Fe/Pd bimetallic nanoparticle. The oxidation effect of nZVI on DDT is greatly improved when Pd is dopped. The highest concentration to be treated under cancerogenesis limit was 110 mg/L. The dechlorination of DDT is more like to DDE via Fe/Pd but to DDD via nZVI. Degradation products concentrations are lowered via Fe/Pd when compared with nZVI. In this study, the bimetallic Fe/Pd nanoparticle was synthesized using the catalytic element palladium to increase the effect of nano zero valent iron (nZVI), in the light of the information obtained from our previous study, in which the nZVI synthesis method was modified. Dichlorodiphenyltrichloroethane (DDT), one of the most widely used persistent organic pollutant pesticides in the world, was investigated in terms of its degradation by Fe/Pd nanoparticles and the difference with nZVI was determined. During the study, the Fe/Pd concentration, initial DDT concentration, and contact time were selected as variables affecting the treatment. The highest possible initial DDT concentration for the treatment with Fe/Pd bimetallic nanoparticle was investigated to obtain the DDT effluent concentration below the carcinogenesis limit, 0.23 µg/L. The highest concentration that could be treated was found to be 109.95 mg/L with Fe/Pd. It was found that 44.3 min of contact time and 550 mg/L Fe/Pd concentration were needed to achieve this treatment.

Quantification of pesticide residues on plastic mulching films in typical farmlands of the North China

Baoyuan Guo, Jiao Meng, Xinyu Wang, Chengnan Yin, Weiyu Hao, Baiwen Ma, Zhang Tao

《环境科学与工程前沿（英文）》 2020年 第14卷 第1期 doi: 10.1007/s11783-019-1181-9

摘要： Pesticide residuals on mulching film of Shandong, Tianjin and Hebei. Detected 29 pesticides in soil and 30 in mulching film. Pesticides on plastic films: 86.4‒22213.2 ng/g and in soil: 9.3‒535.3 ng/g. Pesticides on plastic films 20 times higher than in soil. Plastic debris as new pollutants attracts much attention in the recent years. The plastic mulching films is one of the most important plastic debirs source in the environment. The aim of this work was to investigate the current status of pesticide residues on the plastic mulching films. Based on the QuEChERS method, multi-residue methods for detection of pesticide residues with gas chromatography tandem mass spectrum (GC-MS) and high performance liquid chromatography tandem mass spectrum (HPLC-MS) were developed for the analysis of the pesticides residues in plastic film and soil samples from Tianjin, Hebei and Shandong. The total concentrations of pesticide residues were in the range of 86.4‒22213.2 ng/g in plastic film debris, which was about 20 times higher than that in soil (9.3‒535.3 ng/g). Residual level of pesticides varied greatly in different samples. The historical usage and recent application of pesticides were the main sources for pesticide residues on plastic films and soil. In short, plastic mulching films could act as a sink for pesticides in farmland and the ubiquitous pesticide residues on plastic films should draw more attention.

Miao Zhao, Shufei Li, Qinghong Zhou, Dianming Zhou, Ning He, Zhiyong Qian

《化学科学与工程前沿（英文）》 2019年 第13卷 第2期   页码 377-384 doi: 10.1007/s11705-018-1777-9

摘要： Microbial pesticides can prevent and control diseases and pests of crops, and has become one of the important measures to ensure food and environmental safety. However, the potential harm of microbial pesticides to humans and animals is a serious concern at home and abroad. In this paper, we have investigated the infectivity and pathogenicity of a representative of viral microbial pesticides, helicoverpa armigera nuclear polyhedrosis virus (HaNPV), by specific and highly sensitive polymerase chain reaction technology. The results show that HaNPV can be gradually cleared in a short time after getting into blood of experimental rats, and does not infect other tissues or organs of animals; also indicate that the test subjects are not infectious to experimental rats after intravenous injection of HaNPV. Our method has good specificity and repeatability, and could provide an important reference for establishment of infectivity and pathogenicity detection methods for viral microbial pesticides in future.

Pollution of hazardous substances in industrial construction and demolition wastes and their multi-path risk within an abandoned pesticide manufacturing plant

Sheng Huang, Xin Zhao, Yanqiu Sun, Jianli Ma, Xiaofeng Gao, Tian Xie, Dongsheng Xu, Yi Yu, Youcai Zhao

《环境科学与工程前沿（英文）》 2017年 第11卷 第1期 doi: 10.1007/s11783-017-0901-2

摘要： Pollution pattern of metals and organic pesticide in demolition waste is studied. Organophosphorus pesticide can be everlasting on surface of demolition waste. Leaching potential of pollutants from simulated and onsite waste varies spatially. Direct oral and dermal ingestion, leaching potential into water exceed the limit. Implications for demolition waste management in industrial plants are proposed. Exploration of heavy metals and organic pollutants, their leaching capacity along with health and environmental risks in contaminated industrial construction and demolition waste (ICDW) within a pesticide manufacturing plant were investigated. A maximum content of 90.8 mg·kg Cd was found present in the wastes, which might originate from phosphorus rocks and industrial sulfuric acid used in pesticide production processes. An average concentration of 979.8 mg·kg dichlorovos and other 11 organophosphorus pesticide were also detected. Relatively high leaching rates of around 4.14‰ were obtained from laboratory simulated ICDW using both glacial acetic acid- sodium hydroxide and deionized water. Pesticide pollutants had the strongest tendency to retaining on dry bricks (leaching rate 1.68‰) compared to mortar-coatings, etc. due to their different physical characteristics and octanol-water partioning coefficient. Mobility of pesticide from on-site ICDW by water was spatially correlated to waste types, process sections and human activities, with a flux of leaching rate between 5.9‰ to 27.4%. Risk-based corrective action (RBCA) model was used to simulate the risk of contaminated ICDW debris randomly scattered. Oral and dermal ingestion amount by local workers was 9.8 × 10 and 1.9 × 10 mg·(kg·d) , respectively. Potential leaching risk to aquatic systems exceeded the limit for nearly 75% waste. Environmental and health risk exceedance was found in most ICDW, while the risk value of the most severely contaminated brick waste was 660 times beyond critical level. Implications for waste management involving construction and deconstruction work, waste transferring and regulation supplying were also provided.
