152% rise in private vehicles chokes air quality in capital

HYDERABAD: Environmentalists attribute the prime cause of the city's dwindling air quality to the abnormal growth of private vehicles. According to experts, the vehicle growth rate in Hyderabad and the neighbouring Rangareddy district has been high compared to other districts of the state in the past few years.

A recent study, conducted by the Environmental Protection Training and Research Institute (EPTRI), revealed the increase in the number of vehicles in Hyderabad and Rangareddy is quite high. The major reason for pollution, they say, is due to the rise in the number of vehicles per 1,000 people. The rise, the experts note, has gone from 81.80 vehicles per 1,000 people in 2005 to 253 vehicles per 1,000 in 2016, an increase of 152.76% as compared to the estimated population increase of 113.57%.

As a result of the astronomical rise in the number of vehicles, the city's air is now laced with pollutants, including sulphur dioxide, oxides of nitrogen and carbon monoxide apart from the rising particulate matter (PM) 2.5 levels.

"The main cause of increasing air pollution is vehicular emission," Forum for Sustainable Environment convener S Jeevanand Reddy. "Though advancements in vehicular technology should have brought down the pollution levels, that has not happened in the city. Hundreds of goods vehicles continue to use adulterated fuel to cut costs, adding oxides of nitrogen to the atmosphere. When they react with other particles in the air, they increase the ground-level ozone content. This, in turn, leads to severe health complications. City buses, which are more than 15 years old, are also major contributors of pollutants," he added.

The EPTRI report, which studied vehicles and their impact on the environment between 2000 and 2015 over a three-year period, says "In Hyderabad alone, there is an increase of 241.5 lakh kilometeres distance covered by TSRTC vehicles in a span of seven years (2007-08 to 2014-15)." In 2007-08, the RTC operated 3,180 buses and clocked 1.82 lakh km per bus, while in 2014-15 it operated 3,964 buses and logged 1.7 lakh kilometre per vehicle. In other words, each bus covered 15% less distance in Hyderabad, 4% in Secunderabad and nine percent in Rangareddy district. It is an indication of increasing congestion on roads and possibly the ageing of the fleet. On the other hand, in districts, the kilometres operated per bus has increased though the number of passengers carried per day remains the same.

The report says the air in the twin cities has the highest particulate matter. The contributors for PM10 were vehicular emissions and vehicles over 15 years old. "The PM10 is always higher than the standard 60g/m. We need to make serious efforts to control the particulate matter," it added.
