Also, S showed its association with PM10 concentration suggesting its emission from combustion of sulphur containing raw material of fireworks. The study suggests that the firework emissions significantly affect air quality, increasing the possibility of respiratory illness. }, number = {54}, doi = {10.12944/CWE.13.1.02} }
