KARACHI: While a confluence of natural phenomenon aggravates air pollution in winters, the quality of air in Karachi largely remains poor the whole year; and levels of air pollution may worsen if drastic remedial measures are not taken, experts have warned.
They were speaking to Dawn in the backdrop of recent global air quality data showing Karachi among the worst polluted cities of the world quite a few times this month.
“While the city currently has no government mechanism in place to monitor its air quality, the data being generated privately is very much reliable; and can be generalised over the entire city and used for reference purposes,” said Engineer Danish Khan working as technical adviser to the vice chancellor of the NED University of Engineering and Technology.
