TÓM TẮT
Health risks and perceptions of residents living nearby landflls or stone mines/quarries have been well documented; however, the multiple impacts of these two pollution sources have yet to be investigated. This study
aims at giving insights into the impacts of residents exposed to two pollution sources in Danang city, Vietnam:
Khanh Son landfll and Phuoc Tuong quarry. In this cross-sectional study, 7-point-Likert scale questionnaires
were used to collect information from 314 respondents which were divided into three groups: i) Landfll-Stone
mine (LS) exposed group within 1 km from both sources, ii) Stone mine (ST) exposed group within 1 km from the
stone mine, and iii) the far-exposed group about 2–3 km from the two emission sites. Air pollutants (including
H2S, CH4, and total suspended particles (TSP)) and noise levels were also sampled. In addition, we estimated the
potential health risk assessment due to the exposure to hydrogen sulphide in the study areas.
The fndings have shown that 1) There is a statistical difference (p-value < 0.001) between the two exposed
groups and far-exposed group regarding health risks and residents’ perceptions; 2) Compared to the ST exposed
group, the LS exposed group statistically showed a higher perception to bad odours and skin diseases; lower
satisfaction with regards to the personal health condition and the operation of the landfll; and higher willingness
to change current living locations; and 3) There is evidence to indicate that elevated concentrations of air pollutants are associated with the high self-reported health risks and residents’ perceptions. Urgent actions should
be focused on the LS exposed group, landfll and quarry operations to prevent further adverse health effects
