Ambient Air Quality Assessment in Major Petrochemical industrial Hubs of India

摘要

In The Current Era Of Global Warming, Air Pollution Has Been One Of The Major Sources Of Environmental Pollution In India. Petrochemical Hubs Spread Across Various Industrial Clusters Of The Country Are A Major Source Of Air Pollution. This Paper Primarily Focuses On The Ambient Concentrations Of Pollutants, Namely Pm_(10) So_2 And No_2 And Air Quality Indices In The Major Polluted Petrochermcal Industrial Clusters Of India. Five Petrochemical Industrial Clusters Viz., Ankleshwar, Haldia, Manali, Manglore And Navi Mumbai Earlier Identified By Central Pollution Control Board, Delhi As Critically Polluted Areas In 2009 Have Been Chosen For The Present Study. Air Quality Monitoring Undertaken By Cpcb In These Industrial Clusters During 2014 To 2016 Has Been Used. Rds (Respirable Dust Sampler) Have Been Used For Measurement Of Air Quality Parameters At Various Locations Within Each Industrial Cluster. According To Our Study The Level Of Annual Average Values Of Pm10 Is Increasing In Petrochemical Clusters Like Anklesvar And Manglore And Decreasing In Navi Mumbai Which Is A Good Sign. But In Areas Like Navi Mumbai ,Haldia And Anklesvar The Annual Concentration Of Pm10 Is Beyond The Standard Prescribed By Cpcb For All The Years. The Level Of Ambient Annual Concentration Of So2 And No2 Is Under The Standard Prescribed By Cpcb. The Air Quality Index Calculated Based On Annual Average Concentration "Moderate" In Navi Mumbai In All The Years. The Aqi Range Of Haldia Is "Moderate" In The Years 2014 And 2016 Where As It's Range Is "Satisfactory" In The Year 2013.
