Air pollution is one of a variety of manmade environmental problems. The country has been struggling with this problem for a long period. As per sources at the Environment and Social Development Organisation (ESDO), the populous South Asian nation had been ranked as the second-most polluted country of the world in the previous year. In its capital, dust pollution has reached an alarming stage as its air contains higher proportion of lead and carbon monoxide and other particulate matters. As a result, the city is fast turning into an inhabitable one.
The city residents have already realised how alarmingly dust pollution has been poisoning their lives and degrading the environment. Dust from streets and construction sites, brick kilns, faulty diesel-run vehicles and toxic fumes coming out of industrial units contribute to air pollution to a great extent. Moreover, the number of automobiles has been increasing rapidly in the capital causing frequent traffic congestion that immensely contributes to air pollution.In recent times, the volume of poisonous particles in the city air has already reached far beyond the permissible level for human body. The high concentration of toxic elements in the air results in a foggy blanket in the city sky. According to relevant sources, the pollution levels of lead in the city are among the world’s highest during the dry season. Because of highly-polluted air, the citizens remain under constant health risk. Air pollution is behind the increasing number of patients of respiratory diseases like asthma, bronchitis, pneumonia and lung cancer across the country. Other common diseases caused by dust pollution include heart disease, stroke, acute lower respiratory infections in children and other fatal diseases.
Presently, a countrywide development spree is going on. Because of careless attitude of the authorities, construction materials are dumped here and there irresponsibly without giving any cover over them. In the process, public health is threatened. Authorities concerned must change their attitude towards environmental protection. Emulating the examples of developed countries, preventive measures should be taken to improve the situation. We should prevent dust pollution on an urgent basis for the sake of our very survival.
