Abstract
Rigorous campaign was carried out from July 2013 to June 2014 at the remote and industrial site (Adityapur and Seraikela Kharsawan) in the eastern India aiming to identify and quantify the changes of aerosol chemical composition in the presence of industrial and biomass burning influence. The 24-h PM10 filter samples were analyzed by mass, carbonaceous species, organic ions. The results suggested that the average PM10 concentrations were 165 ± 43.93, 141 ± 30.86 μg/m3 in industrial and remote site respectively. Secondary organic ions (SOC) were the dominant pollutants of PM10. Total carbon was a significant component explaining above 15 % of PM10. The annual average mass concentration of EC, OC, WSOC 26.39 ± 4.56, 5.11 ± 1.82, 18.56 ± 5.30 and 16.27 ± 5.75, 7.70 ± 2.1, 9.65 ± 1.92 µg/m3, OC/EC, WSOC/OC 5.29 ± 1.08, 0.71 ± 0.17 and 2.34 ± 0.75, 0.67 ± 0.16) of industrial and remote site were respectively; and OC/EC particularly in industrial site it reached the highest 5.29 ± 1.08 which demonstrated that SOC should be a significant composition of PM10. The mass fraction of the highlighted species varies seasonally, resulting the air mass trajectories and corresponding cause severe strength. Based on exact mass concentration ratios of EC/OC, WSOC/OC, we predicted that industries and biofuel/biomass burning are a major source of atmospheric aerosols in the eastern part of India. This study provides the scientific baseline data of carbonaceous aerosols for eastern Jharkhand, India.
Highlights
Carbonaceous aerosols (CA) in environments have received special attention recently in the modern India, because of their effects on the local environment, water resources, agriculture production, ambient air quality, decline, visibility and public health (Jacobson 2001)
Air‐mass back trajectories (AMBTs) and aerosol optical depth (AOD) Trajectory analyses are generally simulated in air quality studies to observe the source regions of air parcel blows into a particular region
The results showed that the east to west transport highly affects the chemical concentration of aerosols at Adityapur and Seraikela Kharsawan
Summary
Carbonaceous aerosols (CA) in environments have received special attention recently in the modern India, because of their effects on the local environment, water resources, agriculture production, ambient air quality, decline, visibility and public health (Jacobson 2001). The aim and objective of the present study is to provide most novel and a better understanding of the characteristics of the aerosol particles for carbonaceous species in industrial (Adityapur) and remote (Seraikela Kharsawan) atmosphere.
