ASSESSMENT OF AIR QUALITY IN CAU GIAY DISTRICT, HA NOI
Abstract
Cau Giay district which was established in 1997, is a newly developed district of Hanoi city, with the fastest urbanization rate in the city. However, Cau Giay district has also been facing air pollution, especially the total dust and some other air pollutants, which can affect the health of residents. The study evaluated the air quality of Cau Giay district by the methods of single index and relative air pollution index (RAPI), with monitoring parameters including total dust, CO, SO2, and NO2 collected at 08 different locations in the district. The results show that the total dust exceeds the limit value, the remaining parameters are within the limit according to QCVN 05:2013/BTNMT. According to the RAPI results, 03/08 monitoring points are heavily polluted, 03/08 are lightly polluted and 01/08 points are at the polluted border. The results bring an overall picture of the air quality in Cau Giay district, contributing to the management and control of air quality as well as providing a scientific basis for suggesting suitable solutions towards the sustainable development of Cau Giay district in particular and Hanoi in general.
