Abstract
This article investigates the seasonal changes of particulate matter (PM) attentions, their connection by meteorological in 2020 at a rural location in South India called Amaravati. PM2.5, PM10 absorptions have main winter (54.6727.87 g/m3; 86.269.79 g/m3), lowermost monsoon (9.673.97 g/m3; 24.889.54 g/m3). In addition, the estimated PM2.5/PM10 ratio was 0.49, with a low contribution (0.39) in the monsoon and a high contribution (0.63) in the winter, indicating coarse and fine particle dominance, respectively. With a Pearson correlation coefficient of 0.96, the association between PM concentrations was determined to be strongly positive. However, the impact of PM concentrations on meteorological parameters found a negative correlation during the period of study. The polar bivariate plots exposed considerable influence on PM2.5, breezes blew since the north-westerly as well as southeasterly directions.
