    Environmental impact assessment of rapeseed production using the LCA method: Part two: Life cycle impact assessment by Kiš Ferenc, Đurišić-Mladenović Nataša, Marjanović-Jeromela Ana

    Published 2024-01-01
    “…These primarily include air emissions (carbon dioxide, ammonia, nitrogen oxides, nitrous oxide, sulphur dioxide, and suspended particles), emissions of certain heavy metals into water and soil (hexavalent chromium and zinc), as well as the exploitation of some natural resources, notably arable land, natural gas, and crude oil. The results of the LCIA analysis can be utilized to identify processes and emissions where rationalization or improved control can yield the greatest environmental benefits. …”

    Variations in Sources, Composition, and Exposure Risks of PM2.5 in both Pre-Heating and Heating Seasons by Dingyuan Yang, Zhiyong Li, Ziyuan Yue, Jixiang Liu, Zhen Zhai, Zelin Li, Minglei Gao, Ailian Hu, Wenjia Zhu, Ning Ding, Zhenxin Li, Songtao Guo, Xiangxue Wang, Lei Wang, Jihong Wei

    Published 2022-01-01
    “…On average, SO42− and NO3− (in µg m−3) were found to be markedly enhanced from 3.54 and 11.1 in the PHS to 13.1 and 23.2 in the HS, especially in the case of SO42−, reflecting the increased usage of coal/natural gas. Meanwhile, the ratios of NO3−/SO42− dropped from 2.75 in the PHS to 2.08 in the HS, implying drastic SO42− emissions from coal combustion used for heating. …”

    Key experimental technologies and their development directions for the exploration and production of deep coalbed methane by Xia YAN, Fengyin XU, Xianyue XIONG, Feng WANG, Chunhu LI, Jiyuan ZHANG, Borui XU, Qianhui CHENG, Xiong HU, Xueguang ZHU, Wei LIANG, Pu YUAN, Yanqing FENG, Zhenji WEI

    Published 2025-01-01
    “…ObjectiveDeep coalbed methane (CBM) production enjoys advantages including rapid gas shows, high single-well yield, and continuous resource distribution, which establish deep CBM as a significant target for reserve growth and production addition of natural gas. However, the exploration and production of deep CBM are still confronted with many technical challenges, and there is a lack of studies on key experimental technologies related to the geological characteristics and engineering assessment of deep CBM reservoirs, the occurrence characteristics and production mechanisms of gas and water, the formulation of production systems, and methods for enhanced CBM recovery. …”
