As a decay product of uranium series, 210Pb spreads widely in the nature and imposes strong radiological and chemical toxicity. It is vital to establish reliable and efficient radioanalytical methods for 210Pb determination to support environment and food radioactivity monitoring programs. This article critically reviews analytical methods developed for determining 210Pb in environmental and biological samples, especially new development in recent years. Techniques applied throughout different analytical steps including sample pretreatment, separation, purification, and detection are summarized and their pros and cons are discussed to provide a holistic overview for 210Pb environmental and biological assay.

“…In the literature, as can be seen in Table 1, there are a number of Sr resin based strategies that individually separate one of these three radionuclides [8][9][10] or even isolate two of them -e.g. 90 Sr and 210 Pb [11][12][13], 90 Sr and 210 Po [14] or 210 Pb and 210 Po [5,7,[15][16][17][18][19][20][21] -in different kinds of matrices. The table shows the load sample, resin conditioning media and radionuclide elution media used, these being the main parameters that may have an influence on recovery.…”

This study presents a rapid and novel sequential separation strategy based on extraction chromatography for determining 90Sr, 210Pb and 210Po in drinking water samples. It involves the use of Sr resin for the separation and then liquid scintillation counting and alpha spectrometry for the determination. The experimental results obtained showed that the proper acidic solution to quantitatively retain the aforementioned radionuclides is 3 M HNO3. The optimum eluents were determined for obtaining quantitative recoveries (70–80%) of 90Sr, 210Pb and 210Po. The method was validated with intercomparison water samples and is satisfactory in terms of minimum detectable activities, which are 50% lower than that established in RD 314/2016.

“…The decay of 210 Pb is accompanied by the combined emission of beta particles (16 & 63 keV) and gamma rays (46.5 keV). It then transforms into 210 Bi (5.1 d), which next decays to 210 Po by emitting beta particles (1.2 MeV) [13]. The 210 Po is a pure alpha-emitter, and the emitted particle energy is 5.3 MeV.…”

The measurement of 210Pb is significant in environmental studies. Lead separation in HCl solution is a vital procedure but suffers from poor efficiency with high labor and time costs. To overcome this problem, a novel anion exchange resin was synthesized and characterized by different techniques followed by studies on the adsorption behaviors towards lead in HCl solution. The results suggest that SiPS-N(CH3)3Cl was successfully prepared with small particle size, low water swelling rate, and large specific surface area. The maximum anion exchange capacity resulted from quaternary amine groups was determined to be 1.0 mmol (Cl-)/g.The adsorption activities reached equilibrium within 3 min under selected conditions offering extremely fast adsorption kinetics. The synergistic adsorption mechanism, the multilayer adsorption mechanism, and the competition from co-existing chloride anions were found to be responsible for the lead adsorption performance of SiPS-N(CH3)3Cl. Column experiments showed that the feeding volume of lead and HCl had impact on the chemical yield regardless of the co-existence of high concentrations of FeCl3 (90 mM) and a high flow speed (4.0 mL/min). Based on these results, a separation process integrating SiPS-N(CH3)3Cl and the matched parameters was finally developed and tested. Our work greatly raised the lead separation efficiency in HCl solutions with implications for measuring 210Pb in environmental samples.
