Manipur to phase out old vehicles
Passenger service diesel auto-rickshaw turned out to be main air and noise pollutants in Imphal, the capital city of Manipur
Over 70 percent of diesel auto-rickshaws in passenger service in Imphal city were found to be above 15 years and emission of excessive quantity of smoke, said chairman L Radhakishore of Manipur State Pollution Control Board.
“The government has limited lifespan of vehicles to 15 years but over 70 percent of the vehicles were found to be above 15 years. However, due to non-closure of their service by the government or owners, these vehicles were still on the road,” he said.
He added that “This has caused both air and noise pollution in Imphal city. If we don’t control it now, the city will face a big tragedy. Pollution Control Board will take up action against such vehicles after consulting the concerned government department.”
The chairman was talking to reporters on the sideline of a drive check, particularly passenger service diesel auto-rickshaws by members and officials of the Manipur State Pollution Control Board in Imphal today. The pollution control board has been conducting the drive at different places of city since September 1 last. The drive will continue till September 17.
During today’s drive, the capital city recorded a noise level of 75.4 decibels against the permissible limit of 65 decibels. The check was conducted from 10 am till 3 pm. The chairman added that the air quality of Imphal city was in vulnerable stage as the level of air pollution has been found to be above the permissible limit.
He said to monitor the ambient noise, air and vehicular emission in the city area, a team of three departments were deputed to monitor smoke, air pollution and noise pollution.
Monitoring machines were set up during the drive to make accurate assessments. Radhakishore said during the screening of air, the result was found to be tremendously vulnerable and people were becoming victims of many diseases.
Not only the diesel auto-rickshaws but also commercial vehicles were also monitored for smoke emission. Many commercial vehicles mainly diesel engines were found to be beyond the permissible limit.
It may be mentioned that the permissible level for two wheelers including light motor vehicles which are run on petrol, 3 percent of carbon-monoxide (CO) per volume of emission of smoke has been recommended in four strokes engines and in two strokes engines, 4.5 percent of CO per volume of emission of smokes with reference with the manufacturing of vehicle is recommended.
And for diesel motors with loaded goods, 75 Hartridge Smoke Unit (HSU) and 65 HSU for unloaded vehicles is recommended.
While monitoring a diesel auto, the smoke from the vehicle was found to be 94 HSU which crossed the permissible limit.
Assistant environment engineer Joyshanker Thokchom observed an increase in the content of RSPM (Respirable Suspended Particulate Matter) in the atmosphere to an alarming level.
Under such condition, inhabitants of Imphal city face great risks of getting eye and lung infection as well as skin diseases, the environment engineer cautioned.
Dust pollution coupled with high rate emission of smoke containing sulfur was mainly responsible for the soaring air pollution level in Imphal city, he observed.
