Abstract

Road dust, household total suspended particulate matters (TSP) and PM_2.5 were collected in urban area of Guangzhou, south of China, to investigate the concentrations of total mercury (THg) and methyl mercury (MeHg). The household PM_2.5 concentrations varied between 16.2 and 623μg/m³. The average PM_2.5 level (174μg/m³) from all of the locations exceeded 24-h concentration from WHO air quality guideline The average concentrations of THg and MeHg were: 235μg/kg and 0.392μg/kg in road dust, 600μg/kg and 1.49μg/kg in TSP; 1006μg/kg (104pg/m³) and 1.40μg/kg (0.134pg/m³) in PM_2.5. Risk assessment showed that the Hazardous quotients (HQs) of exposure to Hg and MeHg via road dust and TSP were less than 1, indicating that no adverse risk was manifested. Ingestion of dust was found to constitute a relatively minor pathway of Guangzhou residents' exposure to Hg. Furthermore, human hair samples from 88 Guangzhou citizens were also analyzed to investigate the mercury accumulation in human body in Guangzhou. The average concentrations of THg and MeHg in human hair samples were 869±831μg/kg and 104±108μg/kg respectively. However, no significant correlations of the mercury species were noted between human hair and road dust, TSP and PM_2.5.
