Increase and regional effects of agricultural intensity affect biodiversity (species richness, abundance and may take place. Increased predator diversity should in theory lead to Proceedings of the Royal Society Series B. 272: 203-210.

Lead-210 enters the human body primarily through the diet, but some fraction is inhaled from the air (from the decay of 222 Rn), and some enters as a consequence of smoking cigarettes. Polonium-210 (not considered separately in the table above) also may enter the body by these routes, but a much larger fraction of its intake is from the smoking of cigarettes.

The massic activity, as of Atomic Abundance Ratio, Lead-204/Lead-206 0.027219 ± 0.000027 SRM 982 contains radioactive Lead-210 of natural origin. The massic activity, as of LEAD-210 IN SOIL 1. SCOPE This is a method for separation and measurement of Lead-210 in soil. This method does not address all aspects of safety, quality control, calibration or instrument set-up. However, enough detail is given for a trained radiochemist to achieve accurate and precise results Lead - Lead - Properties of the element: Lead and its compounds are toxic and are retained by the body, accumulating over a long period of time—a phenomenon known as cumulative poisoning—until a lethal quantity is reached. The toxicity of lead compounds increases as their solubility increases.

Unknown quantity: regulating radionuclides in tap water Key words: mass accumulation, sediment accumulation, lead-210 , cesium-137, Greenland, Iceland, fjords Lead-210 enters the human body primarily through the diet, but some fraction is inhaled from the air (from the decay of 222 Rn), and some enters as a consequence of smoking cigarettes. Polonium-210 (not considered separately in the table above) also may enter the body by these routes, but a much larger fraction of its intake is from the smoking of cigarettes. Lead-210 occurs in the environment and its natural variability, as well as the importance of establishing background levels on a media specific basis, before drawing conclusions about the presence of contamina-tion. Several research papers note a natural abundance of Lead-210 in sediments that are generally consistent with these levels: CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Lead-210 is a natural radioactive isotope and a decay product of the Uranium-238 decay chain found in the natural environment along with Radon-222 and Polonium-210.
