“…The study about PM 2.5 -bound PAHs emitted from the economic and financial center of Shanghai in China revealed that the dominant of PAHs concentrations at was HMW (51%), MMW (36%), and LMW (13%), which the city is near the sea [3]. Coincidently, the study from Lui et al [25] revealed that the dominant of street dust sample was MMW-and HMW-PAHs. A large proportion of 4-6 rings PAHs (84.0-91.6%) was the dominant PM 2.5bound PAHs collected from five cities of urbanization and industrialization in Zhejiang Province, China [7].…”

“…-10 for high-traffic region and 2.89 × 10 −11 to 3.71 × 10 −10 for industrial region, which lower than in this study. Moreover, some previous studies reported that the ILCR model analysis of PAHs inhalation was negligible human health risk [7], [17], [25], [37], which could be explained by cancer risk levels for ingestion and dermal contact route including the different dermal exposure area, exposure duration, and ingest a variety of contaminated dusts as a result of hand-to-mouth actions [38]. Childhood, on the other hand, is an especially sensitive stage of development, with cancer risks up to an order of magnitude higher per year of exposure than in adults [39].…”

“…Childhood, on the other hand, is an especially sensitive stage of development, with cancer risks up to an order of magnitude higher per year of exposure than in adults [39]. Children's inhalation of PAHs per unit of body weight of the same volume pollutant was considered higher than that of adults due to their lower body weight [25].…”

BACKGROUND: A city's industrial area's air quality has become a major priority. PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) are one of the most common pollutants in urban-industrial area, and can be linked to health problems. AIM: This study aims to 1) investigate PM2.5 and PAHs emitted from roadside area (RS) and industrial estate (IE) in Rayong city 2) assess the inhalation of PM2.5 and PAHs on the human health of the age group. METHODS: PM2.5-bound PAHs were investigated and thier carcinogenic risk was evalued in this study. PM2.5 samples were collected on quartz filters contained in a mini-volume air sampler and analyzed for PAHs by GC-MS. RESULTS: The average PM2.5 concentrations at RS and IE were 43.3±26.8 and 40.4±21.7 µg/m3, while the values of total PAHs in both sites were 1.68±1.53 and 1.34±1.22 ng/m3, respectively. However, it was found that the PM2.5 and PAHs values were not significantly different (p>0.05). The results revealed that the individual lifetime cancer risk (Ric) of PM2.5 values for children and adults at both sites indicated acceptable cancer risk (10-6 to10-4). According to the incremental lifetime cancer risk (ILCR) values of PAHs for different age groups, exposure to PAHs in PM2.5 through the inhalation pathway was a negligible (<10-6). CONCLUSION: As a result, the PM2.5 concentrations have substantial implications for Rayong city’s environmental management and protection, relating to car emissions and coal combustion.

“…Street dust is the result of those emissions depositing on paved streets which consists of a complex mixture of components including vehicle exhaust, tire and brake pad wear, spillage, and leakage. It is considered as indicator for the quality of urban environment (Liu et al 2019). Dust can easily transport and accumulate many pollutants such as heavy metals and organic compounds (Xu et al 2017).…”

Polycyclic aromatic hydrocarbons (ΣPAHs) were varied from 1250.41-4249.29 ng/g, with an average value of 2809.46 ng/g in street dust of Khamis-Mushait. A maximum concentration of fossil PAHs (ΣFPAHs) was recorded at incinerator and industrial areas representing 69.62% of ΣPAHs. However, the maximum concentrations of carcinogenic PAHs (ΣCARC) and combustion PAHs (ΣCOMB) were recorded at King Fahd Garden and Al-Hayat National Hospital areas, representing 41.70% and 27.46% of ΣPAHs, respectively. Naphthalene (NAP), Acenaphthylene (ACY) and Acenaphthene (ACE) were > (effective range low (ERL). However, ACE was > effective range medium (ERM), ACY, ACE, DBA(dibenzo anthracene) were > Probable Effect Level (PEL). In addition, NAP, fluoranthene (FLT), pyrene (PYR) and benzo(a)pyren (BaP) were > threshold effect level (TEL). The Hazardous indices (HI) for both children and adults were in the following order: ACE > ACY > NAP > PYR > fluorene (FLR) > FLT > benzo(ghi)perylene (BghiP) > phenanthrene (PHN) > ANT. The total HI for non-cancer risks of PAHs exposure were 2.69×10− 2 − 9.91×10− 5 and 2.50x10− 2 − 9.22×10− 4 to adults and children, respectively. These values considered safe level and insignificant non-cancer risks to adults and children. In addition, ACE may pose risk based on acute and intermediate oral exposure. The cluster analysis of dust samples declared the following order for different sources: traffic > industrial > commercial.

“…HPAs são uma classe de compostos orgânicos presentes em misturas complexas no ambiente, com apenas carbono e hidrogênio na sua composição e dois ou mais anéis aromáticos condensados na sua estrutura. Essa classe de compostos pode ser liberada diretamente na atmosfera por ressuspensão e/ou volatilização direta de derivados de petróleo, originando os HPAs petrogênicos ou combustão de compostos orgânicos formando HPAs pirogênicos (Ravindra et al são frequentemente classificados de acordo com a sua massa molecular em: leves, que são aqueles com 2 ou 3 anéis benzênicos e estão geralmente presentes em maiores concentrações da fase gasosa da atmosfera, associados muitas vezes aos aerossóis atmosféricos; Pesados, que são aqueles com 4, 5 ou 6 anéis benzênicos e estão associados as partículas atmosféricas, principalmente no material particulado inalável, ou seja, partículas com diâmetro aerodinâmico menor ou igual a 10 μm (MP10)(Ravindra, 2008).Tais compostos são os agentes carcinogênicos mais amplamente distribuídos no ambiente(Ohura et al 2004, Liu et al 2019. Alguns estudos indicam que o aumento do caráter carcinogênico dos HPAs é em função do aumento da…”
