Particulate matter is one of the most important pollutants responsible for air pollution. Apart from its impact on human health, exposure to a given concentration of particulate matter may, depending on the mix of deposited particles, lead to a variety of impact on the environment. This study has been carried out to assess the concentration of particulate matters in Aizawl city and to examine its impact on the soil and water qualities. The annual mean concentration of PM10 and SPM are found to be 36.38 µg m–3 and 95.75 µg m–3 respectively. Exceedance factor was found to be 0.6 for PM10 and 0.7 for SPM which indicated moderate pollution. The mean mass concentrations of PM10 was found to be highest in winter (51.30µg m–3), followed by pre-monsoon (41.67µg m–3) and post-monsoon (31.65µg m–3) and lowest in monsoon (22.58 µg m–3).For SPM, the highest mean mass concentrations is in winter (131.56 µg m–3) followed by pre-monsoon (110.78 µg m–3), post monsoon(90.92 µg m–3) and monsoon (60.42 µg m–3).Soil pH during the study month ranged from 5.28 - 5.5 , water pH ranged from 7.17 - 7.8 and turbidity ranged from 1.27 NTU – 41.03NTU. PM10 concentration and soil pH showed a statistically significant linear relationship (r= .517, p<0.01). SPM and soil pH also showed a moderately strong positive correlation that is statistically significant (r= .539, p<0.01)
