Plutonium, like other actinides, readily forms a dioxide plutonyl core (PuO 2). In the environment, this plutonyl core readily complexes with carbonate as well as other oxygen moieties (OH −, NO 2 −, NO 3 −, and SO 4 2−) to form charged complexes which can be readily mobile with low affinities to soil.

The environmental management field office pointed to a 2018 DOE study that estimated the radiation dose to a person who might recreate in the canyon is less than 0.1 millirem per year.
Apr. 25—Trace amounts of plutonium from decades of weapons work at Los Alamos National Laboratory have contaminated the Rio Grande at least as far as Cochiti Lake and could be in the regional ...
The Energy Department's Office of Environmental Management at Los Alamos said Thursday it was preparing a response to Ketterer's findings. Ketterer and Coghlan said the concerns now are the continued downstream migration of plutonium, absorption by plants and the creation of contaminated ash following wildfires.
The environmental management field office pointed to a 2018 DOE study that estimated the radiation dose to a person who might recreate in the canyon is less than 0.1 millirem per year. According to the U.S. Nuclear Regulatory Commission, the annual average dose per person from all natural and man-made sources is about 620 mrems.
Disposal of plutonium waste from nuclear power plants and dismantled nuclear weapons built during the Cold War is a nuclear-proliferation and environmental concern. Other sources of plutonium in the environment are fallout from many above-ground nuclear tests, which are now banned.
In the past, one of the largest releases of plutonium into the environment has been nuclear bomb testing. Those tests in the air scattered some plutonium over the entire globe; this great dilution of the plutonium has resulted in the threat to each exposed person being very small as each person is only exposed to a very small amount.
The actinide series is a group of chemical elements with atomic numbers ranging from 89 to 102, [note 1] including notable elements such as uranium and plutonium.The nuclides (or isotopes) thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and (in the case of neptunium ...
