The pollution level in various cities in Punjab remained almost the same as on last Diwali with the respirable suspended particulate matter (RSPM) recorded at 549 micrograms per cubic metre in Ludhiana, more than five times the permissible limit of 100 for residential areas and 150 for industrial areas.
The Punjab Pollution Control Board (PPCB) this year monitored the air and noise pollutions at five places -- Amritsar, Jalandhar, Patiala, Ludhiana and Mandi Gobindgarh -- and in all places pollution was recorded three times more than the permissible limits.
"The data shows there is a slight dip in the RSPM value, but it is still much more than the permissible limits," said a PPCB official spokesman.
Against the 55 dbc limit, the noise recorded around the Golden Temple was 73 dbc.Ludhiana recorded the maximum pollution in Punjab, followed by Amritsar. However, the oxides of nitrogen and sulphur remained within permissible limits.
