“…However, these separation methods require long time processing (Grate et al 2020 ). Over the past decades, highly selective extraction chromatographic materials, such as Sr resin and PS rein (Gimenez et al 2023 ; Mingote and Nogueira 2016 ), have been developed to simplify 210 Pb separation, and new methods involving a degree of automated separation have also been explored. For example, 210 Pb was separated from phosphogypsum using an on-line sequential injection (SI) system combined with an ion exchange column (Kim et al 2008 ).…”

“…PS resin is made by fixing a radionuclide selective extractant in a plastic scintillation microsphere, which can be placed in a solid phase extraction (SPE) cartridge. The target radionuclide is retained in the SPE cartridge, and then measured directly by LSC (Gimenez et al 2023 ). Martinez et al ( 2023 ) employed PS resin in the analysis of sludge samples collected from drinking water treatment plants.…”

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.
