“…The toxicity of heavy metals for crustaceans has been studied by several authors (Mance 1987;Vanegas et al 1997;Wong et al 1993;Wu and Chen 2004). The results of this study confirm that the heavy metals zinc and cadmium are toxic to F. paulensis, an ecologically and economically important shrimp in the coastal waters of South America.…”

In Brazil, pink shrimp (Farfantepenaeus paulensis) is an important commercially exploited species and is an ideal animal for studying the impairment caused by the effects of heavy metals that are often detected in coastal areas. The main purpose of the present study was to detect the acute toxicity of cadmium and zinc to F. paulensis and investigate their effects on oxygen consumption and ammonium excretion, investigations that have not been carried out in this species before. First, the acute toxicity of zinc and cadmium to F. paulensis for 24, 48, 72, and 96 h--medium lethal concentration was examined, which resulted in the following values: 9.39, 6.00, 4.88, and 3.31 mg/l for zinc and 2.35, 1.67, 1.26, and 0.83 mg/l for cadmium. Furthermore, we also found that exposure of shrimp to zinc and cadmium caused an inhibition in oxygen consumption of 25 and 32.4%, respectively, relative to the control. In addition, after separate exposure to cadmium and zinc, elevations in ammonium excretion were obtained, which were 42.85 and 51.85% higher than the control, respectively.

“…Confirming the synergistic effect at low concentrations of these metals, our results coincide with those observed by Vanegas et al (1997), who found that the toxicity of the Cd + Zn mixture for Litopenaeus setiferus juveniles was higher than the sum of their individual effects.…”

Litopenaeus vannamei postlarvae were exposed during 4 weeks to progressively increasing sublethal concentrations of cadmium and zinc (Cd: 8.8, 24, Zn: 81, 160, ), used alone or in mixture, in order to evaluate their joint effect on survival and growth, and on the histological structure of hepatopancreas and gills of the exposed organisms. After exposure to single metals there were no differences between control and treatments in survival and growth, while survival was significantly lower with the highest concentration of the mixture. Growth was also affected and showed a significant dose-related response. No histopathologies were observed in gills of shrimps exposed to single metals, while their hepatopancreas showed moderate to severe changes during the first three weeks. With the mixture, moderate edemas were present in gills lacunae and the hepatopancreas had sloughing of epithelial cells until the third week, but no histological alterations were evident by the end of the experiment. The results of this study show a synergistic effect of the mixture Cd + Zn on survival, growth and histological structure of hepatopancreas and gills of the Pacific white shrimp L. vannamei.

“…In addition, 96 h LC50 values of Cd for larvae of Cancer irroratus and Paragrapsus quadridentatus are 0.25 and 0.49 mg Cd L -1 (MARTIN et al, 1981). Likewise, the 96h LC50 of Zn for larvae of L. vannamei is 1.35 mg L -1 (WU e CHEN, 2004) and for Penaeussetiferus it is 43.87 mg Zn L -1 (VANEGAS et al, 1997). In this study, Cd exhibited greater toxicity to X. kroyeri than Zn.…”

Penaeid shrimps are important resources for worldwide fisheries and aquaculture. In Brazil, Xiphopenaeus kroyeri is an important commercially exploited species, and is an ideal animal for studying the impairment caused by the effects of heavy metals that are often detected in coastal areas. The main purpose of the present study was to detect the acute toxicity of Cd and Zn to X. kroyeri and to investigate their effects on oxygen consumption and ammonium excretion in different temperatures (25 ºC, 20 ºC, 15 ºC), which have not been carried out in this species before. First of all, we examined the acute toxicity of Cd and Zn to X. kroyeri 24, 48, 72, and 96-h medium lethal concentration (LC50). Furthermore, we also found that exposure of shrimp to Cd and Zn caused an inhibition in oxygen consumption of 52.50% and 52.63%, respectively, relative to the control. However, after separate exposure to Cd and Zn, elevations in ammonium excretion were obtained, which were 85.00% and 89.47% higher than the control, respectively. The results shown that Cd and Zn performs higher toxicities to X. kroyeri at higher temperature.Keywords: Marine pollution; heavy metal; Xiphopenaeus kroyeri ; toxicity; LC50 EFEITO DO CÁDMIO E ZINCO NA EXCREÇÃO DE AMÔNIA E CONSUMO DE OXIGÊNIO DO CAMARÃO SETE-BARBAS, DE ACORDO COM A TEMPERATURA RESUMOOs camarões são importantes recursos marinhos explorados pela pesca e aquicultura. No Brasil, Xiphopenaeus kroyeri é uma importante espécie comercialmente explorada e um animal ideal para estudar o impacto causado por efeitos de metais pesados que frequentemente são detectados em áreas costeiras. O principal objetivo do presente trabalho foi determinar a toxicidade aguda do Cd e Zn para o X. kroyeri e investigar seus efeitos no consumo de oxigênio e na excreção de amônia em diferentes temperaturas, uma vez que tais parâmetros ainda não foram determinados para a referida espécie. Primeiramente, foram determinadas a toxicidade aguda (LC50) do Cd e Zn, para X. kroyeri por um período de 24, 48, 72 e 96 horas em três temperaturas (25 ºC, 20 ºC, 15 ºC). Os resultados revelaram que para camarões expostos ao Cd e Zn houve uma inibição do consumo de oxigênio de 52,50% e 52,63%, respectivamente, para a mais baixa temperatura (15 °C). Entretanto, para a excreção de amônia, houve um aumento de 85,00% e 89,47% para a mais alta concentração e temperatura utilizadas em relação ao controle. Conclui-se, portanto, que as toxicidades de Cd e Zn foram mais altas nas temperaturas e concentrações mais elevadas.
