• Po-210
• coal-fired power plant
• meteorological variability
• solid and dissolved samples

The activity concentration of Po-210 from six different samples consisting of raw charcoal, surface sediment, rainwater (suspended solids (SSrw) and dissolved phase (D-rw) and estuarine water (suspended solids (SSew) and dissolved phase (D-ew)), were analyzed. The activity concentration of Po-210 in solid samples was between 7.63 +/- 0.67 and 744.28 +/- 21.12 Bqkg(-1) and in dissolved samples varied between 0.34 +/- 0.03 and 86.33 +/- 6.51 mBqL(-1). On average, Po-210 activity in SSrw sample was the highest, at nearly three times its original form (charcoal). SSew and surface sediment samples were similarly distributed between 15th March and 1st August samplings, but were relatively lower than charcoal and SSrw samples. The natural meteorological variability also enhanced Po-210 distribution and dispersion to a few kilometers from the coal-fired power plant.
