摘要：

The BCT-7800A PLUS VOC online monitor system was employed to measure ambient volatile organic compounds（VOCs）in a typical solvent-using industrial park in Beijing. From January to June 2023，the pollution characteristics，source apportionment，and ozone formation potential （OFP）of VOCs were studied，and the results of a comparative analysis were also discussed between heating and non-heating periods. The results indicated that VOC concentrations from January to June 2023 were（104.21 ± 91.31）μg·m−3 on average. The concentrations of TVOCs under the influence of southerly and northerly winds were（214.18 ± 202.37）μg·m−3 and（197.56 ± 188.3）μg·m−3，respectively. Alkanes were the species with the highest average concentration and proportion，respectively（45.53 ± 41.43）μg·m−3. The VOC concentration during the heating period was higher than those during the non−heating period，with values of（111.57 ± 83.96）μg·m−3 and（87.92 ± 75.03）μg·m−3，respectively. Propane and ethane were the species with the highest average concentration during the heating period. Compared with those in the non-heating period，the average concentrations of three species（propane，ethane，and n-butane）in the top ten species increased during the heating period，with average concentrations increasing by 51.94%，54.64%，and 26.32%，respectively. The source apportionment results based on the positive matrix factorization（PMF）model indicated that the major sources of VOCs in the park during the monitoring period were printing emission sources（4.95%），oil and gas evaporation sources（9.52%），fuel combustion sources（15.44%），traffic emissions sources（18.97%），electronic equipment manufacturing（24.59%），and industrial painting sources（26.52%）. Therefore，industrial painting sources，electronic equipment manufacturing sources，and traffic emissions sources were the emission sources that the park should focus on controlling. Compared with those during non-heating periods；industrial painting，traffic emission，and fuel combustion sources contributed more during the heating period，with VOC concentrations increasing by 15.02%，16.53%，and 24.98%，respectively. The average OFP of VOCs from May to June during the monitoring period was 198.51 μg·m−3 and OVOCs，olefins，and aromatic hydrocarbons contributed the most to OFP，which were 47.41%，22.15%，and 18.41%，respectively. The electronic equipment manufacturing source was the largest contributor to the summer OFP of the park and its contribution rate was 30.11%，which should be strengthened in the future. © 2024 Science Press.
