Assessing Air Quality in Industrial, Urban and Transport Areas in Long Xuyen City, An Giang Province, Vietnam

Abstract

This paper presents an assessment of the current state of the air
quality affected by industrial, urban and transportation activities in
Long Xuyen city, An Giang province in the period 2016-2019. Air
quality monitoring data includes temperature, noise, total suspended
dust (TSP), nitrite oxide (NO2), sulfur dioxide (SO2), carbon
monoxide (CO), ozone (O3), ammonia gas (NH3) and hydrogen sulfur
gas (H2S) were provided by the Department of Natural Resources
and Environment of An Giang province. The results showed that the
quality of the air environment in industrial zones, urban areas and
transport sites were within the permitted standards of Vietnam.
However, the indicators of TSP, NO2, CO, SO2 tended to increase if
it is not well controlled, which can consequently affect the
environment and human health. The environmental managers need
to strengthen monitoring of air environment quality so that there are
timely solutions to overcome pollution problems to ensure public
health. This study recommends that the relevant agency should
measure acetaldehydes, and volatile organic carbons since these
gases are toxic and regularly emitted.
