Partition of organochlorine concentrations among suspended solids, sediments and brown mussel Perna perna, in tropical bays

The brown mussel Perna perna (L., 1758) as a sentinel species for chlorinated pesticide and dioxin-like compounds

“…In contrast to the current findings of the OCP concentrations bioaccumulated by the mussels, a previous publication reported higher concentrations of OCP in sediment and suspended solids from GB than in corresponding samples from SB and IGB (Galvao et al 2014). Because the mussels from GB were reared in an area with greater environmental exposure to the target compounds, 1 month was apparently not sufficient for the transplanted mussels to clearly reflect the differences in all the quantified OCP.…”

“…The ranges of OCP and PCB concentrations observed over the eight sampling months were very comparable to those reported in a previous publication (Galvao et al 2014) in which only two sampling months were considered. A discussion of the extent of contamination in the studied sites can be found in previous studies, whereas temporal variation is the focus of the present study.…”

“…this species is able to reflect environmental exposure (Galvao et al 2012). We also demonstrate that the chlorinated compound concentration observed in sediment has a clearer statistical relationship to bioaccumulation by P. perna than that measured in suspended solids (Galvao et al 2014). The lack of data concerning the bioaccumulation of persistent organic pollutants (POPs) by P. perna is a constraining factor to establish its potentials and limitations as sentinel species for POP biomonitoring.…”

Levels of Organochlorine Pesticides Are Associated with Amyloid Aggregation in Apex Avian Brains

“…Recently, OCs have also been determined in environmental compartments including air, 8 water, 9 and soil 10 and have been detected in various environmental species such as dolphins, 10 bears 11 and mussels. 12 Such studies demonstrate that these persistent chemicals are still a current environmental concern, both for wildlife and for the human population.…”

“…Even in the past three years, OC concentrations have been detected and measured in human blood samples from around the world , as well as in many species of fish , which is thought to represent a significant source of dietary OC intake. Recently, OCs have also been determined in environmental compartments including air, water, and soil and have been detected in various environmental species such as dolphins, bears and mussels . Such studies demonstrate that these persistent chemicals are still a current environmental concern, both for wildlife and for the human population.…”
