t’s a familiar sight in Bengaluru: Vehicles emitting black smoke speeding by as police look the other way. The smoke, which is caused by unburned fuel, contains hydrocarbons in the form of diesel particulate matter (DPM). According to studies by the National Center for Biotechnology Information, Maryland, US, DPM is a mixture of solid and liquid particles suspended in air that contribute to pollution. The problem is common in diesel vehicles. A minor repair can, in most cases, resolve the issue. “Petroleum smoke can lead to cancer. It also leads to chronic bronchitis, cough and breathing difficulty,” Dr Priya Ramachandran, consultant pulmonologist at St John’s Hospital, he informed. “When the sky is clear and the temperature high, these exhaust gases clear up quickly. But when it is cloudy, most of the exhaust stays, and we end up inhaling it. Most respiratory diseases are caused by industrial and vehicular smoke.”

marketing agent. The smoke stays in the air for long after the vehicles have passed. People who cover their faces still end up in-
haling the noxious fumes. Asked if police have taken any measures to regulate vehicles emitting black smoke, Kengeri
traffic sub- inspector PN Manjunath, replied in the positive. “Of course, we take it very seriously. We levy a fine of Rs 100 if we find any vehicle being driven around in that condition. All vehicles must possess the emission test certificate; else they are fined Rs 2,000.” Vehicles emit black smoke because their owners fail to service them on time, the officer added. While black smoke poses a big hazard, invisible fumes also pollute the environment and increase the risk of illnesses. Carbon monoxide, one of the invisible gases emitted by vehicles, combines with hemoglobin to produce carboxyhemoglobin, which is ineffective for delivering oxygen to bodily tissues. In 2011, 52% of carbon monoxide emissions were created by mobile vehicles in the US, according to the United States Environmental Protection Agency. Other harmful gases emitted by vehicles are mono-nitrogen oxides, cardon dioxide and ozone (which irritates the respiratory system when present at the ground level). Experts say it’s high time we hastened the move to eco-friendly vehicles. Better we listened.
City receives uneven rain ‘Bengaluru will be Anjana Basumatary anjana.b@iijnm.org

espite the end of the southwest monsoon, Bengaluru is receiving rainfall due to three factors: Uneven distribution of cyclone circulation, a trough of low pressure and high pressure, and the meeting of easterly and westerly winds. The city will have cloudy weather with thunderstorms till Monday, according to the website accuweather.com. The rain in August and September beat some records. For example, on the night of August 14-15, Bengaluru received 128.7 mm of rain — the highest in a day in 127 years. With the rain have come problems the city is no stranger to. The quality of roads has taken a beating, with potholes appearing all over the city. Filled with water, these craters have cause

In many parts, like Ejipura, roads under sewage that come to the surface because broken drains have overflowed. Dengue cases have increased.
Sundar M Metri, director and scientist at the Meteorological Department, informed The Observer that southern India receives rain during October-November. This is the Northeast monsoon, which comes after the southwest monsoon recedes. The main reason for the heavy rain is that when the southwest monsoon enters the southern India, it brings some contents to the land that, in turn, bring cyclone circulation, low- and high-pressure troughs. “The east-west meeting system which has to enter from the southwest, was not seen. Therefore, uneven distribution of rainfall has been noticed,”he added. “There is a rise in temperature during summer, which is due to global warming. And global warming is caused by the growth of industrialization, greenhouse gases, vehicles and release of methane, sulphur dioxide and carbon dioxide from industries.”

ere’s bad news for India’s technology hub: A research paper recently published in ‘Current Science’ says Bengaluru will become uninhabitable by 2025. The grim picture has been painted by researchers T.V. Ramachandra, an ecological scientist from the Indian Institute of Science, and Bharath H. Aithal from IIT, Kharagpur. The paper says the causes for their inference are: Depletion of natural resources, disappearing lakes, increased carbon footprint, among other reasons. Aithal informed The Observer: “We live on a hill (a reference to the height at which Bengaluru is
located) and need to pump water up. For that, we need electricity and have no surplus of that. Even if we source water from other rivers, that will suffice for not more than three years. The cost of living in Bengaluru is very high. Basic amenities like water, electricity and shelter are not at their best, and Bengaluru’s population is going up by 5% every year. In a few years, we will make it a dead city.” Asked if there’s anything that can be done to save the situation, he replied: “First, we need to decongest Bengaluru. Why do we need everything in Bengaluru? We need to divert talent to Mysuru and other cities. Second, we need to bring back our natural drainage systems. >>Political will needed, page 3
