Karachi has taken off among the top three most dirtied urban areas of the world on Thursday
Kazakhstan's capital city Nur-Sultan (Astana) came to the highest point of the Air Quality Index and Bangladesh's capital Dhaka stayed second in the AQI rundown of most contaminated urban areas with helpless air quality.
Pakistan's biggest city Karachi positioned third from the top in the AQI list with 189 places.
The AQI is determined based on five classifications of contamination: ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
AQI as high as 151-200 is viewed as undesirable, while an AQI rating between 201 and 300 is more destructive and AQI north of 300 is named incredibly poisonous.
Most authorities on the matter would agree, an increment in air contamination used to be recorded in the colder time of year. The air becomes heavier in the colder time of year when contrasted with summer, making toxic particles in the environment move downwards and making the air dirtier. Accordingly, a layer of contaminated particles, including a lot of carbon and smoke, covers a city.
The smoke created by consuming harvest remainders, production lines, and consuming coal, trash, oil, or tires enters the climate, and the impacts of this show up at the beginning of winter and stay till the season's end, specialists said.
In this way, air contamination scopes to incredibly risky levels, seriously compromising the air quality. Lahore and Karachi have been positioned third and fourth separately on a rundown of the world's most dirtied urban communities.
As indicated by air contamination information delivered by the US Air Quality Index, Lahore recorded a particulate matter (PM) rating of 181, setting the city at the third right on the money of the worldwide file of most dirtied urban areas. Karachi, nonetheless, announced a particulate matter (PM) rating of 163 and was pronounced the fourth most dirtied city on the planet.
