NEW DELHI, Nov 5 (Reuters) - India's capital territory of Delhi is keen to use artificial rain to fight air pollution this year, its Environment Minister Gopal Rai said on Tuesday, as deteriorating air quality in the region led to an increase in respiratory illnesses.

While the overall AQI remained in the ‘very poor’ category, the number of stations that recorded ‘severe’ AQI of 400 and above were fewer on Wednesday.

Aggarwal said such patients are experiencing a drop in oxygen saturation and breathing difficulties due to the rising pollution levels

Delhi Environment Minister Gopal Rai held a review meeting on Tuesday with officials at the Delhi Secretariat to assess the steps taken to combat the escalating pollution levels in the national capital.
