Particulate Matter of less than 10
microns in size (PM10) is a source of air pollution.
It is present at a significant level in Kathmandu
Valley's air quality. Even though substantial investment
has been made to improve the city’s air quality,
no improvement has been realized as yet. COMMITTED
conducted a research to determine if construction
related dust particles was one of the sources of pollution
and also approximated its magnitude. In other researches
conducted by other organizations and individuals construction
related dust particles were not considered as a potential
PM10 pollution factor. COMMITTED's research indicates
that the construction materials could have substantial
adverse impact on the city's air quality. The research
concludes that in the past thirteen years (1990-2003)
approximately one million cubic feet of construction
related dust particles such as sand, cement, bricks,
and coarse aggregates were deposited on the streets
of Kathmandu City. This accumulation is increasing
every day and needs immediate measures to halt further
deposition.
