<!– /11440465/Dna_Article_Middle_300x250_BTF –>While Mumbaikars are beginning to worry about the air quality in days to come, air quality experts say that their worst fears might come true once temperatures begin to dip.According to experts, high temperatures being witnessed by the city the during the day helps keep the air quality in the ‘Good’ category but once maximum temperatures begin to reduce, the air quality will only worsen and smog and haze could become a regular feature.Gufran Baig, Project Director, System of Air Quality Weather Forecasting and Research (SAFAR) explained that the particulate matter (PM) levels of Mumbai are relatively higher between 3 am to 7 am currently due to the temperatures reducing slightly, and this resulted in smog and haze early in the morning.”However, since the temperatures begin rising during the day, the air quality has improved but we can expect this trend to change in days to come when the temperatures begin dropping in the city,” Baig said adding that in last two days, interestingly the air quality has been quite good.An air quality expert working with a government organisation based in Mumbai said that this year, the city might face heavy smog gives the fact that a lot of construction work including that of the Metro rail is ongoing across Mumbai.”The levels of PM 2.5 which include extremely fine dust particles is already quite high. Once the mercury drops, it is bound to get attached to water molecules in the air and form layers of smog which is not only known to adversely impact those suffering from respiratory illnesses but also cause allergies and illness amongst others,” said the official, adding that Mumbai’s rising vehicular population has also been aiding air pollution.WINTER IS COMINGExperts say that high temperatures being witnessed during the day help keep the air quality in the ‘Good’ category. However, once temperatures begin to drop, the quality will only worsen, making smog and haze a regular feature.
