NEW DELHI, Oct 30 (Reuters) - The air quality in India's capital worsened on Monday, with pollution levels rising to the highest this year, as low cool-season winds and more burning of stubble in neighbouring states combined to usher in a return of the annual scourge of bad air.

"Delhi is facing the worst pollution levels of this season and the situation is unlikely to improve for the next few days," said a senior official at the Ministry of Earth Sciences' SAFAR monitoring system.

The Delhi government has launched an anti-dust campaign to contain pollution, putting restrictions on construction work while sending out water-sprinkling machines to try to clear dust from the air.

In some parts of the city, the AQI rose past the 400 mark, indicating "severe" pollution levels, government data showed.

The index measures levels of airborne PM2.5 particles that can be carried deep into the lungs, causing deadly ailments like cardiovascular disease and cancer.

The burning off of crop stubble in fields in neighbouring states, while less than last year, was contributing to the pollution in the capital, said the SAFAR official, adding that a drop-off in the wind was aggravating the problem.
