“…The average 210 Po concentration in the Vistula river and its tributaries is similar in comparison to other analyzed rivers: Kaveri and Citarapuzha in India (Shaheed et al, 1997;Haridasan et al, 2001), Tagues in Portugal (Carvalho, 1997), Kuala Selangor in Malaysia (Theng and Abd Ch. Mohamed, 2005), Orantek in Syria (Othman and Yassine, 1996) and lower in comparison to Odiel and Tinto rivers in Spain (Bolivar et al, 2000).…”

“…However, the higher Po-210 activity in the midstream of Langat River than the upstream might be due to the aerial inputs of the radionuclide, accumulation of radionuclide-rich silt and organic matter, and increased biological production [ 50 ] as well as agricultural, industrial and urban waste discharge in the river [ 51 ]; since dissolved oxygen (DO) along with a declining trend ( Table 4 ) and conductivity shows a strongly significant inverse correlation ( r = −0.811) at 99% confidence level ( Table 5 ).…”

The presence of toxic polonium-210 (Po-210) in the environment is due to the decay of primordial uranium-238. Meanwhile, several studies have reported elevated Po-210 radioactivity in the rivers around the world due to both natural and anthropogenic factors. However, the primary source of Po-210 in Langat River, Malaysia might be the natural weathering of granite rock along with mining, agriculture and industrial activities. Hence, this is the first study to determine the Po-210 activity in the drinking water supply chain in the Langat River Basin to simultaneously predict the human health risks of Po-210 ingestion. Therefore, water samples were collected in 2015–2016 from the four stages of the water supply chain to analyze by Alpha Spectrometry. Determined Po-210 activity, along with the influence of environmental parameters such as time-series rainfall, flood incidents and water flow data (2005–2015), was well within the maximum limit for drinking water quality standard proposed by the Ministry of Health Malaysia and World Health Organization. Moreover, the annual effective dose of Po-210 ingestion via drinking water supply chain indicates an acceptable carcinogenic risk for the populations in the Langat Basin at 95% confidence level; however, the estimated annual effective dose at the basin is higher than in many countries. Although several studies assume the carcinogenic risk of Po-210 ingestion to humans for a long time even at low activity, however, there is no significant causal study which links Po-210 ingestion via drinking water and cancer risk of the human. Since the conventional coagulation method is unable to remove Po-210 entirely from the treated water, introducing a two-layer water filtration system at the basin can be useful to achieve SDG target 6.1 of achieving safe drinking water supplies well before 2030, which might also be significant for other countries.

“…In case of Venice lagoon ecosystem where phosphogypsum stockpile impact was also examined 210 Po and 210 Pb concentration were 0.58 ± 0.35 and 0.64 ± 0.28 mBq L −1 , respectively and the authors did not find any direct impact of phosphogypsum on river waters [ 20 ]. The results for the Kaveri river in India were 2.74 ± 0.53 mBq L −1 for 210 Pb and 1.10 ± 0.28 mBq L −1 for 210 Po [ 24 , 25 ]. For the Kali, the Sharavathi and the Netravathi rivers mean concentrations of 210 Po and 210 Pb were 1.28 ± 0.2 and 1.37 ± 0.2 mBq L −1 , 1.30 ± 0.2 and 1.44 ± 0.2 mBq L −1 , 1.00 ± 0.2 and 1.22 ± 0.2 mBq L −1 , respectively [ 17 ].…”

The aim of this work was to determine the concentrations of uranium (234U, 235U, 238U), polonium (210Po) and lead (210Pb) radioisotopes in water samples and to explore the impact of the phosphogypsum stack on the Martwa Wisła waters. The 238U, 210Po and 210Pb concentrations in analyzed water samples reached maximum values of 11.7 ± 0.3, 2.0 ± 0.1 and 3.2 ± 0.1 mBq L−1 and activity ratios were maximally 1.18 ± 0.01 for 234U/238U, 0.041 ± 0.018 for 235U/238U and 0.69 ± 0.10 for 210Po/210Pb. The obtained results suggest that this impact is rather insignificant and does not affect significantly the Martwa Wisła river.
