Effects on dust particles during construction works

A report by urban emission published in Atmospheric Pollution Research proven, transportation is the main cause for emission in Bangalore.23% of air pollution was caused due to the on-road and construction dust. But most of the people accept it is our part of life in our daily life. Bangalore is one of the fast growing cities between 2003 and 2017, added more than 10,000km of road to increase the vehicle population and reduce the traffic on roads. Due to the improve of urban planning and public transport options, emissions of the dust particles will increased by atleast 50% in 2030.

Due to increasing construction activities, pulmonologists says that respiratory cases will increase over the years. During the construction works a lot of chemicals will release. Dr. Sandeep H.S, a consultant pulmonologist at Bangalore Institute of Respiratory Disease and Sleep Disorders (BIRDS) says that cement and sand dust will also lead to respiratory disease. Many chemicals like asbestos, silica, formaldehyde and many other carcinogenic chemicals. Carcinogenic chemicals will lead to cancer. An inflammatory change in the lungs is caused due to the particles which is less than 2.5mm.The explosion of silicon at sandblast will cause breathing difficulties to the human beings.

People, who continuing for long time exposure will lead to higher risk of pulmonary fibrosis, allergic conjunctivitis, cough and other respiratory system issue. Studies says that kids upto six years, the development of the lungs to kids in India and US was same but the ages between 6 and 12 there was a decline in the growth of lungs. One of the reasons for this was pollution explosion.

During site construction the owners must take dust prevention measures to minimizing the impact on the dust particles, made mandatory by the government. Construction should done scientific measures to minimize the loss of dust particles in the air. By watering the area in the site will decrease spreading of dust particles.

The study of World Health Organization (WHO) said that out of 10, 9 people will now breathe only polluted air, which also kills seven million people every year. Due to pollution, one-third of the people death because of stroke, lung cancer and heart disease.
