The Capital on Sunday recorded its worst score on the Air Quality Index for the season. EPCA has said as air quality deteriorates further and reaches "very poor" or "severe" levels, measures under those categories will be enforced.
The task force also recommended closure of all construction activities involving excavation, civil construction, stone crushers, hot mix plants that generate dust pollution during November 1 to 10.
The Air Quality Index showed that air quality was at the "hazardous" level in one part of Delhi and at the "unhealthy" level in other parts yesterday afternoon.
A study reports PM 2.5-related long-term mortality for the year 2016 in 13 megacities of China, India, Bangladesh and Pakistan using an integrated exposure risk (IER) model.
The task force also warned that at beginning of November the situation may get further deteriorated on account of localized emissions during festival and regional contribution due to stubble burning.
The acceptable levels of PM10, the larger particulate matter, and PM 2.5, which measures the finer and more unsafe particulate matter, are 100µg/ m3 and 60µg/m3, respectively.
The measures recommended by the task force are only preventive steps and not to create panic as the air pollution in Delhi is governed by meteorological conditions, he said.
