PANAJI: Falling air quality levels in some parts of the state could make people living in those areas vulnerable to respiratory diseases. Doctors say people with pre-existing breathing conditions, such as asthma, are particularly susceptible.
In its report for 2018-19 the Goa State Pollution Control Board (GSPCB) has singled out the state capital and three major towns Mapusa, Vasco and Mormugao (MPT) for dwindling air quality. It has found respirable particulate matter (PM) to be beyond the permissible limit in all four areas that together accommodate a population of over three lakh.
“If a person is already suffering from a respiratory problem like bronchitis, asthma or chronic obstructive pulmonary disease, air pollution could aggravate it. Poor air quality could also cause an allergy-like breathing condition,” city-based doctor Rufino Monteiro, says.
The annual limit for levels of PM10 (particulate matter that is 10 microns or less in diameter) is 60 microgram/m3. Mormugao (MPT), however, registered a PM10 count of 117 microgram/m3 between April 2018 and March 2019. Vasco recorded the second-highest level of 87, followed by Panaji with 83 and Mapusa with 67.
A source appropriation study is under way in Vasco in view of coal pollution there. It is aimed at quantifying the contribution of emissions from various sources that contribute to air pollution.
Prepared as part of the National Air Monitoring Programme, the GSPCB’s report for 2018-19 has also found PM2.5 to be moderately high in Panaji, Vasco and Mormugao (MPT). It attributes the cause to vehicular movement, construction activities and industrial emission. “Data indicates that levels of sulphur dioxide and nitrogen dioxide are within permissible limits,” it adds.
