report abstract:

in recent years, the assessment and control of emerging pollutants in the ecological environment have garnered increasing attention. this report focuses on particulate matter emissions and explores new insights. firstly, through literature meta-analysis, through-water sampling, and indoor processing analysis, the plant retention mechanism and process of particulate matter were studied. the influence of precipitation factors on the intensity and process of particulate matter output by plants was also explored. secondly, through literature scientometric analysis and emission assessment accounting, the precursor bvocs emissions of particulate matter were studied. the newly developed bvocs assessment method aims to evaluate the biogenic methanol emitted by crops during the growing season, helping to reveal the relationship between bvocs emissions and key influencing factors. lastly, using visual inspection and quantitative analysis methods, the aging, fragmentation, and release of agriculturally biodegradable mulch films under uv irradiation were studied, revealing the formation of biodegradable microplastic particulate matter. these works provide theoretical support for future studies on the obstruction and output dynamics and mechanisms of particulate matter on plants; scientific basis for selecting highly efficient particulate matter-purifying tree species; and scientific support for optimizing agricultural practices, reducing adverse environmental impacts, and promoting sustainable agriculture.
