In February 2013, Nepal’s Ministry of Environment released data on air pollution, which was described as “alarming.”
Republica
(February 26, 2013) reported the latest air quality data which was recorded in
the first week of February. In Kathmandu Valley (made up of three districts:
Kathmandu, Lalitpur, and Bhaktapur) recorded PM10 “far beyond the national air
quality standard.” PM10 (Particulate Matter 10) is the level of fine particles
in the air with diameters less than or equal to 10 micrometres. Nepal’s
national air quality standard of pollutant PM10 is 120 micrograms per cubic
metre (UG/M3 – chemical vapours, fumes, or dust in the ambient air as a
measurable unit). Bhaktapur measured 150 UG/M3, Thamel measured 200 UG/M3 and
Putalisadak measured 300 UG/M3. However, Machchhegaun showed just 70 UG/M3.
Six air
quality monitoring stations in Kathmandu Valley, funded by the Danish
government, with two stations in Kirtipur and Patan funded by the Ministry of
Environment in 2002, remained inactive for 5 years. Currently only four air
quality monitoring stations are functional. The two government-funded stations
will not be functioning for some time because the ministry is having difficulty
finding spare parts for the equipment and maintenance. The four functioning stations
(Danish-funded) received spare parts “with great difficulty.”
The previous
air quality data was released in 2008. At that time, Patan, Thamel and
Putalisadak (suburbs in Kathmandu Valley) showed the highest air pollution
levels ranging from 120 UG/M3 to 135 UG/M3.
ICIMOD, the
International Centre for Integrated Mountain Development in Nepal, recently
released a report stating that the Kalanki to Thankot route is “massively
polluted.” The study of Kathmandu Valley residents, from 2009-2011, reported a
significant rise in respiratory diseases. ICIMOD called for immediate steps to
tackle the problem of air pollution in the Valley.
The rise in
air pollution in Kathmandu Valley is attributed to the rapid increase in
urbanization and the accompanying increase in the number of vehicles
contributing to gases and solid particulate matter in the air, the ICIMOD
report stated. The high level of particulate matter in the air contributes to
health risks, particularly of permanent residents, and particularly in the dry
winter months. The report stated that the main pollutants in the Valley were
particulate matter, carbon monoxide, and sulphur dioxide.
The ICIMOD atmospheric environment specialist maintained that the city did not need a device to measure the pollutants because it was noted in the health of residents on a day-to-day basis. However, as in other countries, air quality stations can warm residents of unusually high levels of pollutants, and the government can take steps to reduce levels. With recording and monitoring, the measurements can ensure government accountability as well as provide evidence of progress.
