Air Pollution And Respiratory Diseases In Children
The term air pollution is applied where there is an excessive concentration of foreign matter in the outdoor atmosphere is harmful to human being. Such a polluted atmosphere is a source of bacterial, viral, organic, inorganic & gaseous agents which can affect the Respiratory System, More than 100 contaminats have been identified, which are grouped into air & gaseous pollutants, from sources like vehicles, combustion, industrial processes etc. Major respiratory diseases associated with air pollution are chronic bronchitis, allergic disorders, ARI, asthama & lung cancers. Children are more vulnerable to air borne pollution due to narrower airways, rapid breathing, and more outdoor movement.
Leakage to toxic gases from factories can produce toxic damage to lungs leading to irritation, pulmonary oedema, chemical pneumonia, bronchiolitis obliteranse, necrosis & even death. Symptoms include chocking sensation, cough, air hunger and sense of compression in chest.
In a study of 3000 children exposed to a toxic gas (MIC) at Bhopal, pulmonary function tests showed significantly lower values for mean FVC, as compared to control group, suggestive, of small airway obstruction, on long term follow up, progressive airway obstructive disease pattern was detected.
X-rays showed pneumonitis, emphysema, emphysema, collapse, fibrosis pulmonary opacties & intersticial pulmonary oedema. Preventive measures include, keeping away the child from smokers, environmental health education, pollution monitoring & public awareness., 百拇医药
