We use state-of-the-art techniques to measure a range of toxic species found in our environment, including trace elements. Exploiting the deep-photyping of CoLaus|PsyCoLaus study, we study the associations of toxic species with risk factors (including genetic data and cardiometabolic traits) and disease outcomes.

The study began in 2021 and trace elements were measured in more than 6500 participants of the baseline survey of CoLaus|PsyCoLaus.

What data have been collected?

We are using an ICP-MS that is a high-throughput approach for simultaneously measuring the different trace elements in biological matrices. So far, the following trace elements have been measured: Ag, Al, As, Be, Bi, Cd, Co, Cr, Cu, Hg, I, Li, Mn, Mo, Ni, Pb, Pd, Pt, Sb, Se, Sn, Tl, V, Zn.

Current phase

ToxiLaus is still ongoing (2021-currently)
