In the month of Baisakh, the average pollution level in Bhaktapur was recorded to be 83 microgram per cubic meter, and in Kathmandu the pollution level was recorded to be 63 microgram per cubic meter. The National Ambient Air Quality Standard has set a standard of 40 microgram per cubic meter to protect public health. However, frequent rainfalls in this season has caused pollution levels to decline.
Dhiraj Pokharel, general secretary of Leaders Nepal, blames the polluted air flowing from Kathmandu to Bhaktapur for the high levels of pollution there. Air flows from Balaju through Pokhrel added, “Another reason for pollution is low chimney hoods in factories today. The earthquakes last year destroyed all high chimney hoods, and only small ones remain functional.”
Dr Amod Pokhrel, a professor of University of California, said, “The main source of pollution is the use of partially burnt wood and coal as fuel, and smoke from vehicles that run on petrol and diesel.” Air pollution has a stronger impact on the health of young children and the elderly. Health issues such as respiratory problems, high blood pressure, and eye infection can arise due to pollution.
