Abstract
Human health risk assessment of aromatic hydrocarbon compounds (BTEX) in the air surrounding a domestic solid waste incinerator in Vinh Phuc province, Vietnam were investigated. Four campaigns of sampling were implemented in the period from April 2022 to November 2022. Wide occurrence of BTEX contamination in the air surrounding a domestic solid waste incinerator. Total concentrations of 05 BTEX ranged from 51.73 to 263.90 ?g/m-3 (mean 131.29 ± 83.9 /m-3) and from 120.47 to 345.55 ?g/m-3 (mean 204.9 ± 88.9 ?g/m-3), respectively. The ILCR risk coefficient for people exposed to Benzene and ethylbenzene is quite high, ranging from 3.07 x 10-2 ÷ 9.04 x 10-2 and 1.18 x 10-2 ÷ 8.63 x 10-2, respectively; For HQ hazard coefficient, it is ranging from 0.11 to 5.96. However, to assess the overall impact of BTEX on incinerator operators, therefore, ecological risk assessment should be further investigated.
