Guwahati, Nov 11: Pollution Control Board of Assam has cautioned that high decibel Chinese firecrackers are having a hazardous impact on the State's environment.
PCBA officials say majority of the Chinese products produce sound beyond permissible limits - from 150 to 200 decibels, resulting in noise pollution. The permissible limit for the State is 90 decibels at 5 metres from the source area.
An official of the PCBA, however, claimed that the firecrackers made in Barpeta are below the permissible limit of 90 decibel.
"Last year, we raided many places in the city and seized high-decibel firecrackers. But it seems the district administration is callous in this regard. We haven't seen any crackdown this year even as the high decibel Chinese crackers continue to be sold in the State," the official said. PCBA reports said Bongaigaon, despite being an industrial town, has shown better level of air quality index compared to the other towns of the State.
Dibrugarh, Mangaldai, Lakhimpur, Sivasagar and Silchar also had "satisfactory" levels of air quality index, according to the survey carried out between January and June this year.
However, in Guwahati, Golaghat, Margherita, gaon, lbari, Tezpur and Tinsukia, "moderate" levels of pollution were found, which could lead to breathing discomfort among people with lung and heart diseases, children and other susceptible adults.
gaon had the worst air quality among the towns in the State during 2014 in the period between January-June this year.
