As for the mass flux of tritium through the main stem of the Mississippi River into the Gulf of Mexico, data indicated that approximately 780 grams of tritium has flowed out of the River and into the Gulf between 1961 and 1997, [70] an average of 21.7 grams/yr and 7.7 PBq/yr. Current fluxes through the Mississippi River are 1 to 2 grams, per ...
[citation needed] In Australia products containing tritium are licence exempt if they contain less than 1 × 10 6 becquerels per gram (2.7 × 10 −5 Ci/g) tritium and have a total activity of less than 1 × 10 9 becquerels (0.027 Ci), except for in safety devices where the limit is 74 × 10 9 becquerels (2.0 Ci) total activity.

Assuming a density of 114 grams per cubic metre (0.192 lb/cu yd) at $100/l helium-3 would be about a thirtieth as expensive as tritium (roughly $880 per gram ($25,000/oz) vs roughly $30,000 per gram ($850,000/oz)) while at $2000/l helium-3 would be about half as expensive as tritium ($17,540 per gram ($497,000/oz) vs $30,000 per gram ($850,000 ...

Since one in about every 6,400 hydrogen atoms is deuterium, a 50-kilogram (110 lb) human containing 32 kilograms (71 lb) of body water would normally contain enough deuterium (about 1.1 grams or 0.039 ounces) to make 5.5 grams (0.19 oz) of pure heavy water, so roughly this dose is required to double the amount of deuterium in the body.
Microplastics were detected in almost every seafood sample found off the coast of the western U.S. in a recent study. The particles were found in the edible tissue of six different species of fish.
