Life on earth is threatened both by environmental pollution and overpopulation. Natural phenomena contributing to pollution have always existed but anthropogenic activities are increasing contamination of air, soil and water. Waters are especially polluted by metals. The main threats to life from toxic metals are associated with exposure to Pb, Cd, Hg and As, which accumulate in organisms. Overpopulation means more food is required but the amount of arable land is declining

“…Many studied showed, bivalves do not regulate the level of some metals within their body (Stanly et al, 2008) and they can deflect the metals contamination from surrounding area. Thus, bivalves to be considered as good biomonitor agents for heavy metal monitoring in aquatic ecosystems (Elfwing and Tedengreen, 2002;Yap et al, 2003;Zelika et al, 2003;Nicholson and Lam, 2005;Zorita et al, 2006;Vlahogianni et al, 2007;Maanan, 2008). Gulf of Chabahar on the Iranian coasts along the Oman Sea is a developing area; traditionally this area is used for fisheries and aquaculture activities of the local people.…”

“…Trace metals are taken up by small organisms, entering food chains and bioaccumulating in upper trophic levels (Ruelas-Inzunza andPáez-Osuna 2008, Jara-Marini et al 2009). Since bivalve mollusks are sedentary and benthic filter feeders (Maanan 2008), they have been used to determine the levels of contamination by metals in coastal ecosystems (Lim et al 1995, Einollahi-Peer et al 2010, Chaharlang et al 2012). There are reports on the use of oysters (Le et al 2015), mussels (Licata et al 2004) and clams (Fang et al 2003) as biomonitors of heavy metals in different countries.…”

The pen shell (Atrina maura) is a filter-feeder bivalve that may accumulate metals in its body. The objective of this study was to determine seasonal concentrations of copper (Cu), chromium (Cr), cadmium (Cd), nickel (Ni), lead (Pb), arsenic (As), zinc (Zn), and mercury (Hg) in soft tissue and muscle of A. maura cultivated in a farm located in the southeastern coast of the Gulf of California from summer 2011 to summer 2012. Except for Cu, the higher metal concentrations were found during the dry season (winter 2011-spring 2012). The mean values in soft tissue fluctuated from 0.064 ± 0.01 µg/g (dry weight [dw]) for Hg to 485.66 ± 71.12 µg/g (dw) for Zn, while for muscle they varied from 0.058 ± 0.03 µg/g (dw) for Hg to 64.83 ± 4.90 µg/g (dw) for Zn. Concentrations of cadmium (18.15 µg/g in soft tissue and 1.82 µg/g in muscle, wet weight [ww]) and lead (2.31 µg/g in soft tissue, ww) exceeded the permissible limits (36.3, 3.64, and 2.31 times, respectively) recommended by the sanitary regulations of the official mexican standards. The results suggest that variation of metal levels in cultivated pen shell could be influenced by seasonality and anthropogenic activities such as agriculture and aquaculture developed around the culture zone. Continual monitoring of metals in farmed pen shell is recommended.Palabras clave: concentración de metales, variación estacional, bivalvos, cultivo, monitoreo RESUMEN El callo de hacha (Atrina maura) es un bivalvo filtrador que puede acumular metales en su cuerpo. El objetivo de este trabajo fue determinar las concentraciones estacionales de cobre (Cu), cromo (Cr), cadmio (Cd), níquel (Ni), plomo (Pb), arsénico (As), zinc (Zn) y mercurio (Hg) en tejido suave y músculo de A. maura proveniente de una granja del sureste del Golfo de California, del verano de 2011 al verano de 2012. Las concentraciones más altas de todos los metales, con excepción del Cu, se encontraron en la estación de secas (invierno 2011-primavera 2012). Los valores promedio (peso seco) en A.M. Góngora-Gómez et al. 58el tejido suave fluctuaron de 0.064 ± 0.01 µg/g para Hg a 485.66 ± 71.12 µg/g para Zn, mientras que en músculo variarion de 0.058 ± 0.03 µg/g para Hg a 64.83 ± 4.90 µg/g para Zn. Las concentraciones promedio en peso húmedo para cadmio (18.15 µg/g en tejido suave y 1.82 µg/g en músculo) y plomo (2.31 µg/g en tejido suave) excedieron los límites permitidos (36.3, 3.64 y 2.31 veces, respectivamente) por la regulación sanitaria de las Normas Oficiales Mexicanas. Los resultados sugieren que la variación de metales encontrada en el callo de hacha pudo estar influida por la estacionalidad y las actividades antropogénicas desarrolladas en los alrededores de la zona de cultivo, como agricultura y acuacultura. Se recomiendan monitoreos continuos de metales en callo de hacha cultivado.
