Essential and non-essential total eleven metals and metalloids (

Distribution of Heavy Metals (Ni, Co, Pb, Cd, Hg) in Tissues of European Chub (Squalius cephalus L.) from the Middle Course of the Nitra River, Slovakia

“…Higher muscle concentrations are known from the lower course of the Nitra River [4]. Lower muscle Cd levels have been presented in this same fish species from the upper Nitra River [1], Jihlava and Morava Rivers, Morava River basin (Czech Republic) [15,[17][18], as well as in the muscle of related Aegean chub from Tersakan and Sarıçay streams (Turkey) [14] and Squalius svallize form the lower Neretva River (Croatia) [7]. Lower gonads levels of Cd than our results have been published for European chub from the upper Jihlava River (Czech Republic) [15], as well as for related Squalius svallize from the lower Neretva River (Croatia) [7].…”

“…Statistically significant higher levels (P<0.05) of cobalt were detected in spring than in the autumn season. Lower mean concentrations in muscle of European chub are known from the middle and lower parts of the Nitra River [3][4], originated from autumn season, from the Kızılırmak River basin, Turkey [16], as well as from the Tersakan and Sarıçay streams, Turkey, in the muscle of related Aegean chub [14]. Tissues order of cobalt accumulation (data from both seasons) was: kidneys > gonads > hepatopancreas > muscle.…”
