Air quality Index is a tool for identify the current situation of air quality. Six unique techniques for Calculating Air quality Index (AQI) in light of four poisons synergistic impact viz., PM10, PM2.5, SO2 and NO2 were utilized to look at the predominant surrounding air quality in the review area Air quality index (AQI) or air pollution index (API) is commonly used to report the degree of seriousness of air pollution to public. Various strategies were dev•eloped in the past by different scientists/environ•mental offices for assurance of AQI or API but there is no all- around acknowledged strategy exists, which is suitable for all circumstances. Different method uses different collection work in calculating AQI or API and furthermore thinks about various kinds and numbers of contaminations. The planned purposes of AQI or API are to distinguish the unfortunate air quality zones and public revealing for seriousness of openness of unfortunate air quality. The vast majority of the AQI or API records can be broad•ly order as single poison file or multi•pollut•ant list with various total technique. Every indexing strategy has its own trademark strength and weakness that influence its reasonableness for particu•lar applications. This paper endeavor to introduce are view of all the significant air quality records developed worldwide.
