Hyderabad: It is not surprising that air pollution in and around busy roads is getting worse, especially when traffic is slow. Road pollution has caused asthma in 3.5 lakh children in India, the second most important after China, in 2015, reveals a Lancet study that analyzed 194 countries.
According to some studies, India ranks below other countries for this measure because, although levels of other pollutants (especially P2.5) in the country are among the highest in the world , Nitrogen Dioxide (NO2) levels (between 2010 and 2012) in India cities appear to be inferior or comparable to European and American cities.
According to WHO data, about 1.5 million people died as a result of air pollution in India in 2012. Globally, both indoor and outdoor air pollution has caused almost 7 million deaths, or 11.6% of deaths in 2012, making it the biggest risk to environmental health in the world, according to the 2016 global health statistics.
According to the World Urban Health Database of the World Health Organization (WHO), about 98% of cities in low- and middle-income countries have more than 1 year of age. a resident do not meet the standards set in the air quality guidelines for air quality.
Epidemiological studies have demonstrated a link between different levels of air pollution and various health effects, including mortality, exacerbation of asthma, chronic bronchitis, respiratory tract infections, ischemic heart disease and stroke. .
Pollution due to road traffic emissions is said to be the main source of concern. According to doctors, 80% of the ambient nitrogen dioxide is the cause. With nearly one thousand vehicles add each day to the existing volume in the form of recordings.
"TRAP (traffic-related pollution) directly causes hyperreactivity of the airways, oxidative stress and direct irritation of the mucous membranes of the respiratory tract." In TRAP, pollution by diesel exhaust gases is mainly at the Origin of 90% of outdoor air pollution.Status children live 300 meters from the roads and are the most affected.There is a risk of exacerbation of asthma that can be fatal. Dieting rich in fruits and vegetables could help asthmatic children, "said Dr. M Naresh, MD), a junior resident at Osmania Hospital.
"Children exposed to air pollution are at increased risk of asthma and allergic rhinitis and are likely to develop chronic lung diseases later.They also risk contracting allergic conjunctivitis and skin allergies such as dermatitis. Vehicle smoke can increase the risk of lung cancer later in life, "said Dr. Ramesh Babu Dampuri, consultant pediatrician and teen doctor and general practitioner at Niloufer Hospital in Hyderabad.
Acute effects of exhaust gas exposure include nose and eye irritation, changes in lung function, respiratory changes, headache, fatigue, and nausea. Chronic exposures are associated with coughing, sputum production and decreased lung function.
