PM10‐bound polycyclic aromatic hydrocarbons (PAHs) levels were monitored at urban locations (outdoor/indoor) within the city of Madrid between May 2017 and April 2018. Fourteen PAH congeners were measured, potential emission sources were identified as were potential carcinogenic risks. The ΣPAHs averaged 0.577 and 0.186 ng/m3 in outdoor and indoor air, with a high linear correlation per individual mean PAH and month. The largest contributors to the ΣPAHs were the high‐molecular‐weight PAHs. Principal component analysis‐multiple linear regression results showed that emissions from diesel and vehicular processes explained 27% and 23% of the total variance of outdoor and indoor air, while combustion processes accounted for 30% and 25% in ambient and indoor air, respectively. During the cold season, biomass burning plus coal and wood combustion were additional sources of outdoor emissions. The heavy‐, medium‐ and light‐molecular‐weight PAH originating from outdoor sources accounted for 72%, 80%, and ~60% of the indoor levels of the three respective PAH groups. Average BaP concentration was 0.029 and 0.016 ng/m3 in outdoor and indoor air, respectively. Estimated BaPeq concentration averaged 0.072, 0.035, and 0.027 ng/m3 for outdoor, indoor, and indoor‐generated individual PAH concentrations, respectively. The estimated carcinogenic risk falls within the range of acceptable risk targeted by the US‐EPA.

“…Beyond China, PMF modeling also identifies differences in PAH sources . For example, at Ulsan, Korea, industrial emissions and vehicle, especially diesel usage, contributed over 80% of the PAHs in soil, [31][32] while in the Gulf of Thailand, the contributions of PAHs from petroleum residue and air-water exchange was estimated to be 44% and 25% respectively, owing to direct land-based inputs (large amounts of sewage, runoff, and sediments), gas absorption and the topography of the semi-enclosed tropical marine embayment. 33 Along the Jhelum riverine system of the Lesser Himalayan Region in Pakistan, biomass combustion and vehicular emissions via long range atmospheric transportation from neighboring countries were revealed as important sources of the PAHs.…”

“…Emissions of PAHs have greatly increased by the extensive industrialization in Ulsan and Pohang [5,23,24]. Contamination with PAHs in the agricultural lands surrounding these areas is highly likely to occur since many are located near roads or adjacent to industrial areas [25,26].…”

Monitoring polycyclic aromatic hydrocarbon concentrations and distributions in rice paddy soils from Gyeonggi-do, Ulsan, and Pohang

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants that are released by incomplete combustion of carbon-containing materials. The top soils of rice paddies were collected from Gyeonggi-do (18 sites), Ulsan (20 sites), and Pohang (19 sites) in Korea to assess the spatial distribution and potential sources of PAHs. The total concentrations of 15 PAHs in the soils were 19.53-672.93, 125.01-3106.27, and 51.94-8106.21 mg/kg in Gyeonggi province, Ulsan, and Pohang, respectively. The concentration of 7 key carcinogenic PAHs were followed the order: Pohang (38.54-4826.63 ng/g) > Ulsan (28.54-1561.39 ng/g) > Gyeonggi province (19.53-206.51 ng/g). Three-ring PAHs were predominant in the soils from Gyeonggi-do while 3-5 ring compounds were abundant in the agricultural soils from the two industrial regions (Ulsan and Pohang). The PAH isomeric diagnostic ratios indicated that PAH contamination in the two cities mainly originated from pyrogenic sources. The principal component analysis indicated that pyrogenic coal burning and residential biomass combustion were major contributors to the soil contamination in the two cities. The transportation of PAHs through the air from industrial complexes and high volume of traffic may influence the PAHs distribution in the soils of the two cities in Korea.
