Heavy and trace metal concentrations in three rockpool shrimp species (Palaemon elegans, Palaemon adspersus and Palaemon serratus) from Tenerife (Canary Islands)

Abstract

Trace metal concentrations (Fe, Cu, Co, Zn, Ni and V) were investigated in three rockpool shrimp species (Palaemon elegans, Palaemon adspersus and Palaemon serratus) from six littoral sampling sites (polluted and non-polluted) of Tenerife in the Canary Islands (Central Eastern Atlantic), Spain. Sex ratio for all three species has been determined: females predominate over males in all species and significant differences in total length and cephalothorax length was detected between sexes, being females larger than males. By other side, concentrations of trace metals were determined in whole specimens. Higher mean values for every metal were observed in P. adspersus. In males, higher values were observed in P. elegans and P. serratus, whereas in P. adspersus, mean values are higher in females. Finally, mean concentrations of trace metals studied were higher, in general terms, in the two clearly polluted stations: Santa Cruz of Tenerife commercial harbour and its fishery dock dependency.

Possible Influence of Natural Events on Heavy Metals Exposure from Shellfish Consumption: A Case Study in the North-East of Italy

“…In this regard, heavy metal contamination is recognized as a public health hazard because of the widespread diffusion of these compounds in the environment, including the marine ecosystem ( 7 ). Heavy metals can be accumulated by marine organisms due to their presence in water and sediments or in the marine food chain ( 8 , 9 ).…”

Occurrence of trace elements in Mediterranean mussels (<em>Mytilus galloprovincialis</em> Lamarck, 1819) from an experimental pilot farm in the Calich Lagoon (Sardinia, Italy)

“…Heavy metals generated from anthropogenic sources such as industrial effluent, urban run-off, mining operations, and atmospheric emissions are transported through rivers or by air and finally accumulate in coastal areas (Olmedo et al , 2013 ; Azizi et al , 2018 ). Chemical pollution in coastal shellfish-growing waters is a worldwide problem (Almeida and Soares, 2012 ) and is recognized as a public health issue (Lozano et al , 2010 ). Several bivalve species live in estuaries that are subjected to several anthropogenic pressures, thus being exposed to high levels of trace elements (Forstner and Wittmann, 1979 ).…”

Assessment of metal concentrations in oysters and shrimp from Atlantic Coast of the Democratic Republic of the Congo

“…Numerous studies have been conducted to assess the pollution status of marine ecosystems by heavy metals using different bioindicator organisms in order to evaluate the potential risks to human health (e.g. Lozano et al, 2010;Dionísio et al, 2013;D€ okmeci et al, 2014;Nascimento et al, 2017;Welty et al, 2018). The use of these organisms, (like oysters and shrimp) as biological sentinels has proved to be useful for environmental monitoring due to their sensitivity and rapid response to environmental pollutants (Knakievicz, 2014;Szefer et al, 2006;Jonathan et al, 2017).…”
