New publication on trace elements concentrations in long-finned pilot
whales stranded in northern Patagonia, Chile.
On behalf of my co-authors I would like to share with you a recent
publication on concentrations of trace elements in long-finned pilot whales
stranded in northern Patagonia, Chile. The reference and abstract are given
below and the paper is available at:
Reference: Garcia-Cegarra, A.M., Padilha, J.A., Ferreira-BRaz, B.,
Ricciardi, R., Espejo, W., Chiang, G., Bahamonde, P. Concentration of trace
elements in long-finned pilot whales stranded in northern Patagonia, Chile.
Marine Pollution Bulletin 151, 110822,
The use of trace metals and rare-earth elements (REEs) is increasing in the
mining, metallurgic, electronic,and automobile industries due to their
magnetic, heat-resistant and phosphorescent properties. While large amounts
of these metals are released to the environment, the toxic consequences in
marine organisms are poorly understood. In Chile a mass stranding event of
long-finned pilot whales (LFPW) (Globicephala melas) occurred in 2016 due
to unknown consequences. Al, Ce, Cr, Cu, Tl and Zn concentrations were
analyzed in LFPW blubber tissue and correlated with body size and age class
of individuals. While Al, and Zn were higher in juvenile individuals, Ce,
Cu, Cr and Tl were higher in adults. This study provides the first base
line of trace metals and RRE in LFPW from the southern hemisphere and
demonstrates the existence and persistence of trace elements in marine top
predators from remote ecosystems like the Chilean Patagonia.
