DOI: 10.1016/j.jinorgbio.2017.07.020
Abstract: In case radioactive materials are released into the environment, their incorporation into our digestive system would be a significant concern. Trivalent f-elements, i.e., trivalent actinides and lanthanides, could potentially represent a serious health risk due… read more here.

DOI: 10.1080/10408347.2022.2135984
Abstract: Chlorination of seawater forms a range of secondary oxidative species, collectively termed "chlorine-produced oxidants" (CPOs). These compounds do not have the same biocidal efficacy, the same fate and behavior in the marine environment, the same… read more here.
