Cold weather along with high levels of pollution is making a deadly combination for Delhi NCR. Since, the very beginning of November, pollution has continued to remain under severe category. However, this level of pollution is not an unusual affair for residents of Delhi as every year they battle such hazardous situations. Such level of pollution is considered dangerous thereby causing asthma, severe lungs and brain disorder diseases. This year, the combined mass activity of stubble burning over the neighboring states of Punjab and Haryana and cracker burning on the festivities of Dussehra, followed with that of Deepavali lead to a rise in pollutant levels over Delhi-NCR.
