“…Kim et al (1998) present data with similar distribution and, in a general way, within the same orders of magnitude as the present work. Elevated Cu variation in this tissue might be linked to body condition, as suggested by Malinga et al (2010). These authors also suggested that the variation of Cu concentrations could be due to different stages of development of the gonads, which was visually confirmed in the present study.…”

Trace elements in tissues of white-chinned petrels (Procellaria aequinoctialis) from Kerguelen waters, Southern Indian Ocean

et al. 2014

International audienceThe use of seabirds to assess marine contamination by trace elements in areas remote from pollutant emission points has already been done at various latitudes. Nevertheless, little information is available concerning the Southern Indian Ocean. Determining the contaminants levels, there appears necessary not only due to several deleterious effects reported in literature, but also as previous studies have highlighted elevated concentrations of cadmium (Cd) and mercury (Hg) in mollusks, crustaceans and fish. Within this context, the white-chinned petrel appears as a key species due to its lifespan, diet and trophic position. Thirty-three accidentally killed (collision with lights/bycatch in longline vessels) individuals collected in Kerguelen waters were analysed for Cd, copper (Cu), Hg, selenium (Se) and zinc (Zn) in liver, kidney, pectoral muscle, feathers and for mature males, testis. Elevated Hg concentrations (average 58.4 lg g-1 dw in liver) are likely due to the presence of mesopelagic prey in the diet of Procellaria aequinoctialis. Cd concentrations (average of 65.7 lg g-1 dw in kidney) can be attributed to a high level of fisheries offal consumption, as well as crustacean and squid ingestion. Correlation of Hg with Se indicates its detoxification by co-precipitation, and correlation of Cd with Zn suggests its displacement by Cd on metallothioneins binding sites. This work also indirectly confirms ecological data (range and diet composition) from the wintering period of the species, which is rather scarce. Seasonal diet change and moulting accounted more for the obtained results than sex of the birds

“…There are few studies of the levels of heavy metals in the brain tissue of birds. Compared to other studies, the level of heavy metals in brain tissues in this study were higher than other studies in other parts of the world, including Zator and Milicz, Poland (Binkowski and Sawicka-Kapusta 2015), wetland in north western Poland (Kalisińska et al 2004), Gdansk Bay Baltic Sea, Poland (Szefer and Falandysz 1987b) Nilgiris, Tamil Nadu, India (Jayakumar and Muralidharan 2011), lagoon of Marano, Italy (Leonzio et al 1986), BjØrØya and Jan Mayen Artic (Malinga et al 2010), Pomeranian Bay, Poland (Kalisińska and Szuberla 1996).…”

The concentrations of four heavy metals zinc (Zn), lead (Pb), nickel (Ni) and cadmium (Cd) were determined in liver, kidney, muscle and brain of nine species of birds from the Chahmimeh Sistan from Iran, to assess metal levels and the potential risk to birds, and to the people who eat them. Higher levels of all metals were found in the brain of waterfowl than in the tissues of other birds (P < 0.05). There were no significant gender differences in heavy metals in all tissue. Levels of Pb, Cd, Ni and Zn in the liver and kidney varied as a function of feeding habitats; the median levels were higher in invertebrate predators than fish predators and omnivorous species (P < 0.05). Short distance migrating birds had higher median levels of heavy metals in liver and kidney than long distance migrant birds (P < 0.05). Ni levels in liver and kidney tissues in 56% of birds were higher than the critical thresholds levels for effects in birds. Our data indicate that environmental exposure to metals were higher in the wintering populations of birds in the Chahnimeh of Sistan from Iran. Concentration Zn, Pb and Cd in a small percentage of birds, and 56% nickel level in liver and 56% kidney concentrations in birds, were above toxicity levels. Examination EDI, EWI and HQ of the edible tissues (kidney, Liver and muscle) of these birds showed that their consumption is a threat to the health of the people of the region.

Determining the exposure frequency and daily intake of birds, the Hazard Quotient for edible tissues (kidney, Liver and muscle) of these birds showed that their consumption provides a health risk to people consuming them.
