Pesticides in stormwater runoff−A mini review

Cheng Chen, Wenshan Guo, Huu Hao Ngo

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 5, doi: 10.1007/s11783-019-1150-3

Abstract: • The sources and pathways of pesticides into stormwater runoff were diverse. • Factors affecting pesticidesin stormwater runoff were critically reviewed. • Pesticides mitigation strategies were included in thisreview. • The current knowledge gap of the pesticides in stormwater runoff was identified.In this context, pesticides have been identified as the key knowledge gap as far as reusing stormwaterThis paper reviewed the presence of pesticides in stormwater runoff in both rural and urban areas.

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

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 2,   Pages 231-237 doi: 10.1007/s11783-011-0316-4

Abstract: 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.

The Chemicals Input Status and Transformation Path of the Planting Industry in China

Yi Xiaoyan,Yuan Meng and Yin Changbin

Strategic Study of CAE 2017, Volume 19, Issue 4,   Pages 124-129 doi: 10.15302/J-SSCAE-2017.04.020

Abstract:

This paper examines the total inputs and regional characteristics of chemical input in China since the 1990s, analyzes existing problems of chemical input, and puts forward a general transformation idea, transformation path, and security system for chemicals. Certain phenomena that result in obvious problems for this industry include the excessive use and a low utilization rate of chemicals, regional imbalances in chemicals input, imbalanced crops, and irrational crop structure within the planting industry. In addition, input methods need improvement. It is essential to transform the production mode by optimizing regional layouts, reforming planting systems, developing new chemicals, and adopting precision agricultural technologies. It is also necessary to strengthen support for and promote the green and sustainable development of farming based on scientific and technological innovation, integrated demonstrations, subsidy systems, standard specifications, and industry/university/research institute collaborations.

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

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 1, doi: 10.1007/s11783-017-0901-2

Abstract: 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.
