Other Side of Diwali
Firecrackers are “power packed” with potassium nitrate, carbon & sulfur.The suspended particles hog like a thick blanket reducing visibility and suffocating the atmosphere. In fact studies have demonstrated that during Diwali festival the concentration of sulfur dioxide increased by 10 times & that of nitrogen dioxide, PM10(Particulate matter of size less than 10 microns) & TSP(Total Suspended Particles) increased by 2 to 3 times. The Overall air pollution during Diwali increases by about 200 %. The larger particles( 5 to 10 microns) are filtered in the nose & throat, smaller particles (3 to 5 microns) arrive in the bronchial tube, bronchi (2 to 3 microns), bronchioles (1 to 2 microns) & in alveoli (0.1 to 2 microns) & finally in the blood. The Diwali smoke potentially leads to development of various respiratory ailments like –Allergic bronchitis, acute exacerbation of bronchial asthma & COPD (Chronic Obstructive Pulmonary Disease), allergic rhinitis, laryngitis, sinusitis, pharyngitis, common cold, acute eosinophilic pneumonia, reactive airway dysfunction syndrome
