Lead and Lead-210 in Rainwater
Nature, 1967THERE is a continuing interest in the possible toxicity to man and animals from the present and future concentrations of lead in the environment. The importance of environmental lead was emphasized by Monier-Williams in 1938 (ref. 1), and has since resulted in numerous studies2–4.

Science, 1961
The distribution of lead-210 which enters the oceans subsequent to its production in the atmosphere by radon-222 decay, shows an increase with depth in sea water. By use of a simplified two-layer model of the ocean, a residence time of lead in the upper mixed layer of less than 2 years is derived.

Journal of Oceanography, 1973
This is the first detailed study on the distribution of lead-210 in the Japan Sea water. The content of lead-210 ranged from 9.3±2.1 dph/l in the surface water to 3.4+-0.8 dph/l in the deep water—a quite low content as compared to that in the deep water of the North Pacific.

Lead-210 sedimentation in Lake Ontario
Environmental Geology and Water Sciences, 1992The sedimentation rates and diffusive sediment mixing coefficients at several Lake Ontario locations have been derived from measurements of unsupported210Pb profiles in sediment cores. The values of mixing coefficients obtained in the present study are significantly lower than those obtained previously through an analysis of porosity profiles.

Lead-210 content of food samples in India
Radiation and Environmental Biophysics, 1980The paper presents results of measurements made on cereals and composite meal samples collected from Bombay market for their lead-210 content. The details of sampling and analytical chemistry procedures are also given. The Pb210 contents of most of these samples were in the range of 1--5 pCi/kg of cereals samples.

Lead-210 in Some Human and Animal Tissues
Nature, 1961Measurements were made of the levels of stable Pb and Pb/sup 2//sup 1// sup 0/ in samples of human and animal bone and liver. Results are tabulated and compared with results of similar measurements. (C.H.)

Lead-210 in the circumpolar South Atlantic
Deep Sea Research Part A. Oceanographic Research Papers, 1990^(210)Pb activity in circumpolar waters of the South Atlantic is characterized by a sharply defined maximum at intermediate to shallow depths that is strongly correlated with the oxygen minimum. This feature, present throughout the Southern Ocean, is most likely locally maintained rather than advected from elsewhere.
