This article was received in January 2023, and it speaks on the gaps of knowledge we have on tritium. It highlights how no study so far assesses how tritium affects the environment at an ecosystem level. It also highlights how most information is biased towards other animals, with fewer studies focused on the effects of tritium on humans. Most studies have also only tested on high concentrations of tritium. 

I will quote three paragraphs from the article.

“ To the best of our knowledge, there is no study assessing the impact of tritium at the ecosystem level. Furthermore, most studies reviewed have been carried out using very high concentrations of tritium, which makes it possible to discover mechanisms of action and detect potential effects at higher levels of biological organisation. These studies, however, do not always reflect the damage observed in a realistic exposure scenario”

“Different responses to tritium exposure, from molecular to behavioural, have been reported in various taxonomic groups during early life stages, with the potential transmission of effects across generations proposed through epigenetic mechanisms. Although little is known about these mechanisms, “omics” techniques could help to fill knowledge gaps and elucidate the relationship between molecular and organismal level responses “

“This review has shown that available data are heavily biased towards marine bivalves, fish and mammals (i.e., rodents), and mainly cover laboratory rather than field studies and with a focus on tritium exposure as HTO. Lacking are investigations exploring the uptake pathways and consequences of other forms of tritium like OBT or tritiated particles”
