This study found that research mainly focused on VOC emission characteristics, effects on air quality and health, and VOC emissions under climate change. We combined the bibliometric method with the evolution tree and Markov chain to identify research focus and uncover the trends in VOC emission sources.
Volatile organic compound (VOC) emissions have attracted wide attention due to their impacts on atmospheric quality and public health. However, most studies reviewed certain aspects of natural VOCs (NVOCs) or anthropogenic VOCs (AVOCs) rather than comprehensively quantifying the hotspots and evolution trends of AVOCs and NVOCs.
Changes in BVOC emissions may have important impacts on ozone and atmospheric particle formation, which consequently impact the atmospheric chemistry, radiation, and climate. These interactions involving BVOCs will be investigated by using a coupled meteorology–chemistry with the BVOC emission model.
During the period 2011–2020, transport (22.14%) and plant emissions (13.79%) were the largest emitters of VOCs, followed by manufacturing industry and construction (11.89%), fugitive emissions from fuels (9.04%), non-energy products from fuels and solvent use (8.98%), and biomass burning (7.02%).
Volatile organic compounds (VOC) play important roles in atmospheric chemistry, plant ecology, and physiology. Biogenic VOC (BVOC) emitted by plants is the largest VOC source.
Given these factors, reducing VOC emissions to the atmosphere from wastewater treatment plants can be achieved by draining crude oil from process equipment into a substandard oil collection system, thereby minimizing flow to the treatment plant. The inlet water temperature must be controlled to reduce air emissions.
