Trees for contaminated and radioactive sites (poplar, forest irrigation): uses in research
Also: hybrid poplar, TCE phytoremediation, tritium phytoremediation, Savannah River
Trees that take up contaminants. Poplars can break down some organic pollutants such as TCE; for radioactive elements, plants only take up or move them (for example tritium transpired as water vapour) and do not destroy radioactivity.

Only what the cited papers report.
Poplars transpire part of the TCE they take up into the air rather than degrading all of it. doi:10.1021/es960564w
Tritium phytoremediation efficiency fell as more irrigation water was applied (r² = 0.99). doi:10.1306/eg.06210404018

Ammar and colleagues reviewed sources, mechanisms and methods for phytoremediation of soil contaminated with radioactive cesium and strontium.

Newman and colleagues found hybrid poplars took up trichloroethylene (TCE) and degraded it to trichloroethanol, trichloroacetic acid and dichloroacetic acid, and also transpired measurable TCE.

Rebel and colleagues modelled a Savannah River Site project where tritium-contaminated seep water is used to irrigate forest so trees transpire the tritium, keeping it out of surface waters, and compared irrigation strategies by efficiency (tritium transpired/applied).
