Microplastics were pervasive throughout the sediment analysed (10 cm depth), yet lead-210 (210Pb) activities were confined to the upper 4 cm, indicating this layer to be ~150 years old and thus the presence of microplastics far exceed the production of modern plastic.

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.
