The particulate 210 Po/ 210 Pb ratio was 1.6–5.1 in surface water and 2.5–10.4 in bottom water indicating that 210 Po tends to be more enriched in deep water particulate material as compared to surface material. The 210Po and POC are significantly correlated (r2 = 0.93) with the POC/ 210 Po ratio varying between 205 and 2094 μmol C …

Lead-210 (210Pb) is the most important isotope among the different isotopes of lead, as it is one of its radioactive isotopes and has a long half-life (22.3 years), so it is used to date sediments for the past hundred years, and this has made it extremely important in many different environmental studies [7]. The origin of 210Pb from the

Lead 210Pb is a naturally occurring radioactive nuclide element of the uranium (238U) radioactive series. It is produced as a result of the decay of so-called short-lived progeny of 222 Rn, which comes from the decay of 214 Po (99.98%) and 214 Bi by 219 Tl (0.02%). 210Pb is subject to beta decay into 210Bi.
