Volatile organic compounds (VOCs) are ubiquitous in the atmosphere, posing significant adverse impacts on air quality and human health. However, current research atmospheric VOCs mainly focuses specific regions or industries, without comprehensive national-level analysis. In this study, a total of 99 articles China published from 2015 to 2024 were screened, data their concentrations, source apportionment, health risks extracted summarized. The results revealed that annual average concentrations TVOCs groups generally increased then decreased between 2011 2022, peaking 2018-2019. A distinct seasonal pattern was observed, with highest occurring winter, followed by autumn, spring, summer. TVOC emissions highly concentrated northern eastern China, contributed alkanes alkenes. Source apportionment indicated vehicle sources (32.9% ± 14.3%), industrial (18.0% 12.8%), other combustion (13.0% 13.0%) primary China. There positive correlation (

As an important emission source of volatile organic compounds (VOCs), the plastic products industry has relatively few studies conducted on it. Therefore, this paper selects seven enterprises in Jiaozuo City for monitoring and analysis. By calculating ozone formation potential secondary aerosol industry, environmental impact is understood. Through calculation using entropy method, species subject to priority control are determined. The results show that City, daily-use manufacturing highest VOCs concentration, which 20.18 mg/m³, followed by pipe (3.96 mg/m³), synthetic leather made plastics (1.93 packaging boxes containers (0.27 mg/m³). Among them, OVOCs main components contributing substances include ethyl acetate, n-butanal, 2-butanone, etc. aromatic hydrocarbons respectively, propionaldehyde, ethylbenzene, toluene respectively.

Abstract. Chemical losses of ambient reactive volatile organic compounds (VOCs) is a long-term issue yet to be resolved in VOC source apportionments. These substantially reduce the concentrations highly species apportioned factor profiles and result underestimation contributions. This review assesses common methods existing issues ways loss impacts analyses suggests research directions for improved Positive matrix factorization (PMF) now main analysis method compared other mathematical models. The using any apportionment tool processing data analyzed losses. Estimating initial VOCs based on photochemical age has become primary approach effects PMF, except selecting low-reactivity or nighttime into analysis. Currently, concentration only considers daytime reactions with hydroxyl (⚫OH) radicals. However, ⚫OH rate constants vary temperature, that not been considered. Losses from O3 NO3 radicals, especially alkene species, remain included. Thus, accuracy estimation uncertain. Beyond developing accurate quantitative approaches losses, consumed quantification different contributions secondary aerosols are important additional future research.

The coal chemical industry produces a large amount of volatile organic compounds (VOCs), and the emission characteristics associated impact on environment health residents are still unclear. This study determined VOC concentrations compositions in Jinjie Coal Chemical Industry Park which is located northern China. average total measured VOCs (TVOCs) industrial areas summer winter were 231.5 103.2 μg/m3, higher than those residential (123.7 70.3 μg/m3), respectively. Aromatics, carbonyls, alkanes dominant classes areas, while halocarbons, alkenes had where not only affected by emissions also other anthropogenic sources. Formaldehyde, ethylene, m/p-xylene prevailing contributors to ozone formation potential (OFP), aromatics (e.g., m/p-xylene, o-xylene, ethylbenzene) showed largest contribution secondary aerosol (SOA) both seasons. Using source apportionment method, gasoline production, coking emission, fuel combustion, solvent coating, vehicle exhaust five major areas. With reliable estimations aspects, exposures acrolein formaldehyde posed highest non-carcinogenic carcinogenic risks, results demonstrated that substantial environmental co-benefits could be achieved reducing from process, diesel-fueled vehicles Park. Prioritizing establishment efficient air pollution measures tightening standards, especially for hazardous VOCs, recommended according findings valuable work.
