There is also strong scientific evidence that high salt (NaCl) intakes lead to increased risk of hypertension.

Both problems are important because of the small isotope shift and the very small natural abundance of 210 Pb, at most on the order of parts per billion. Laser isotope separation of lead, if developed, can produce a reliable, cost-effective and very large (on the order of one to ten metric tons per annum) supply. uFallout radionuclides, such as caesium-137 (137Cs), lead-210 (210Pb) and beryllium-7 (7Be), assist in (i) establishing changes in soil redistribution patterns and rates in large catchment areas and in (ii) evaluating the efficiency of soil conservation measures in controlling soil erosion and water quality. Subsequently, zebra mussel abundance was expressed on a semi‐quantitative abundance scale of 0–3 (3 = abundant and 0 = absent) for each lake. We also used sub‐fossil remains to verify recent presence of zebra mussel in each lake providing data that were not reported by Salgado, Sayer, Brooks, Davidson, Goldsmith, et al. .

is greatly Lead 210 has a relatively short half-life of 22.3 years. The amount of 210 Pb remaining in most samples is statistically insignificant after about seven half-lives. Thus, this technique cannot be used to date materials older than 150 years. uranium-thorium dating (a.k.a. uranium-series, uranium series disequilibrium, thorium 230 dating) Lead is a bluish-white metal of bright luster. It is very soft, highly malleable, ductile, and a poor conductor of electricity.

Lead isotopes are used for medical and scientific purposes. Pb-206 and Pb-207 can both be used to produce the medical radioisotopes Bi-205 and Bi-206.
