“…However, the values determined in the present study are well above those reported in the literature. Indeed, in dolphins stranded along the coasts of Puglia (Cardellicchio et al, 2000), on the Croatian Adriatic coast (Šuran et al, 2015) and along the Murcia coast (Martínez-Lopez et al, 2019), the average concentrations of cadmium were always lower in all three organs than the values recorded in this study of dolphins stranded along the coasts of Campania and Calabria (Southern Italy).…”

“…There are many studies on the determination of heavy metals in the organs and tissues of delphinids, especially Stenella coeruleoalba, beached alive or dead, in various oceans and seas (Law, 1992;Baptista et al, 2016;Shoham-Frider et al, 2016;Rojo-Nieto et al, 2017;Martínez -Lopez et al, 2019). Some papers report the concentrations of cadmium and mercury in delphinids from the northern Tyrrhenian Sea, stranded along the coasts of Liguria and Tuscany, from the Ionian Sea and Adriatic Sea, stranded along the coasts of the Puglia region, and in Sicily, particularly in the Strait of Sicily (Leonzio et al, 1992;Monaci et al, 1998;Bellante et al, 2012;Cardellicchio et al, 2000;Cardellicchio et al, 2002).…”

Mercury and cadmium in striped dolphins (Stenella coeruleoalba) stranded along the Southern Tyrrhenian and Western Ionian coasts

Pollution from heavy metals is becoming a serious and widespread problem due to their persistent and bioaccumulative nature, moreover in the Mediterranean Sea, threatening food safety and the health of humans and marine animals. Cadmium and mercury in particular, are considered two of the most toxic metals to living organisms. Their presence is associated with the contribution of human activity, implying an increased level in the different environmental compartments and the inevitable bioaccumulation in the food chain.In this study, levels of cadmium and mercury were determined in liver, kidney, and muscle tissue of dolphinid specimens of Stenella coeruleoalba stranded in different locations along the coastal areas of the Tyrrhenian and Ionian Sea in Southern Italy, during the period 2015–2018 by Atomic Absorption Spectrophotometry. Data were compared with those reported for other locations along the Mediterranean sea. The correlations between biometric data (body length, weight and gender) and cadmium and mercury concentrations in samples of cetaceans were statistically analysed in order to investigate the risk these contaminants may pose to the delphinids health.Examination of the pattern of contaminants revealed a significantly high distribution for mercury in all the matrices analyzed (liver, kidney and muscle tissue). On the contrary, elevated concentrations of cadmium were found only in liver (range: 0.005 - 8.95 mg/kg w.w.) and kidney (range: 0.005 - 34.1 mg/kg w.w.) due to accumulator role of these organs in long-term exposures.

“…6 The effects of heavy metal contamination on riverine cetaceans are poorly understood, 4 but the bioaccumulation in vital organs can lead to disturbance in growth, reproduction, the immune system, and the central nervous system. 6,7 Thus, it is crucial to know the chemical contaminants in tissues of cetaceans, which can potentially bioaccumulate, for the effective conservation of river dolphins, especially those considered endangered species, such as the Amazon river dolphin. 8 The Amazon basin contains four species of cetaceans, the tucuxi (Sotalia fluviatilis) and three species of Amazon river dolphin or boto (Inia geoffrensis, Inia boliviensis, and Inia araguaiaensis).…”

Detection and quantification of heavy metals in blood and milk of Amazon river dolphin (Inia geoffrensis) (Cetartiodactyla: Iniidae) using wavelength‐dispersive X‐ray fluorescence spectrometry

River dolphins of the genus Inia are among the most endangered cetacean species in the world. However, information on the elemental constitution of the blood and milk of these species is still quite scarce. This study aims to evaluate the wavelength‐dispersive X‐ray fluorescence (WD‐XRF) spectrometry to detect and quantify heavy metals in blood and milk samples of a free‐ranging female Amazon river dolphin (Inia geoffrensis) from Central Amazon, Brazil. The WD‐XRF method detected and quantified 14 elements (Na, Mg, Al, Si, P, S, Cl, K, Ca, Cr, Mn, Fe, Zn, and Cu) in the samples analyzed, in which 13 elements were in the blood and 14 were in the milk. The WD‐XRF method did not detect some heavy metals, including those already described for the Amazon river dolphin milk (e.g., mercury) detected by other analytical methods, such as atomic absorption spectrometry (AAS). However, it is possible that the samples analyzed may come from a non‐contaminated individual. Therefore, the joint use of different analytical methods is recommended for future analyses. In addition, both blood and milk samples presented high concentrations of some metals, and the health risks of botos are discussed. This result demonstrates that the WD‐XRF method is a viable analytical procedure for detecting certain elements and quantifying their concentrations in liquid biological samples of Amazonian cetaceans.
