“…Particle size distribution was determined by the Robinson's pipette method, following organic matter oxidation with H 2 O 2 30% and dispersion with sodium hexametaphosphate (Calgon). The sediment organic matter was determined by weight lost upon ignition of dry sediment in a muffle furnace at 450°C for 6 h (LOI) (Beaudoin 2003;Heiri et al 2001;Marín-Guirao et al 2005a).…”

Individuals of Hexaplex trunculus, Tapes decussatus, and associated sediments were collected from 16 coastal sampling plots of the Mar Menor lagoon (SE Spain), and the metal and As concentrations were determined. The sediments had maximum values (in milligrams per kilogram dry weight [d.w.]) of 7,132 for Zn; 6,975 for Pb; 5,039 for Mn; 501 for As; 74 for Cu; and 9.1 for Cd. Specimens of H. trunculus could be collected from all the sampling plots, and it was found that concentrations of Zn (between 883 and 3,130 mg kg −1 d.w.), Pb (between 0.09 and 222 mg kg −1 d.w.), Mn (between 7.6 and 17.7 mg kg −1 d.w.), As (between 144 and 418 mg kg −1 d.w.), and Cd (between undetectable and 8.4 mg kg −1 d.w.) in soft tissues significantly increased when concentrations in sediments increased. H. trunculus apparently regulated Cu assimilation (concentrations between 17.7 and 47.2 mg kg −1 d.w.) in its soft tissues. T. decussatus was very scarce or even absent from sites with higher metal and As contents in the sediments. Hence, H. trunculus could be used as a bioindicator of metals and As pollution, but not T. decussatus. Based on our results, a human health risk exists because the species analyzed are collected from the studied zone and so are consumed by the population.

“…Shallow depth, limited size, con fined circulation and weak hydrodynamics associated with ecological connectivity with adjacent systems also make these environments unstable and sensitive to natural and anthropogenic pressures. Ecological connectivity triggers exchanges of biota and organic and inorganic materials, frequently re sulting in the accumulation of allochthonous organic matter and pollutants and possibly in alterations of the natural equilibrium (Marín-Guirao et al 2005, Boubonari et al 2009). Of all pollutants, metals are among the most ubiquitous and increasingly reach coastal ecosystems from both point sources (e.g.…”

Transitional environments are vulnerable interface systems, ecologically connected with adjacent systems by several biotic or abiotic flows. The coastal system of the Marinello ponds (Tyrrhenian Sea, Italy) is affected by a colony of yellow-legged gulls Larus michahellis (Naumann, 1840), resident on the cliff beside the ponds. To investigate the role of the gull colony as a potential source of allochthonous non-essential trace metals (As, Cd, Pb and total mercury, THg) and the consequent metal trophic transfer to the biota in the ponds, we collected guano, surface sediment and biota from 3 ponds with different levels of avian input. The highest concentrations were observed in guano and surface sediment of the seabird-influenced pond, suggesting that trace metals have undergone biotransport mediated by seabirds. To test for biomagnification, the trophic pathways of the ponds were first identified by δ

“…This test has been shown to be sensitive to metals (Kobayashi 1977;Kobayashi and Okamura 2004;Marín-Guirao et al 2005;Kungolos et al 2009;Caplat et al 2010), organotin compounds (Kobayashi et al 2008), radiation (Matranga et al 2010;Bonaventura et al 2005), and acidification (Byrne et al 2010;Moulin et al 2011), among other factors. It has also been found to be a valuable tool for evaluating complex chemical mixtures (in which additive, synergistic, and antagonistic effects may affect toxicity) that might be released into the marine environment (Xu et al 2011).…”

In aquaculture, disinfection of facilities, prevention of fish diseases, and stimulation of fish growth are priority goals and the most important sources of toxic substances to the environment, together with excretory products from fish. In the present study, embryos of two species of sea urchin (Paracentrotus lividus and Arbacia lixula) were exposed to serial dilutions of six antibiotics (amoxicillin (AMOX), ampicillin, flumequine (FLU), oxytetracycline (OTC), streptomycin (ST), and sulfadiazine [SFD]) and two disinfectants (sodium hypochlorite (NaClO) and formaldehyde [CH(2)O]). Alterations in larval development were studied, and the effective concentrations (ECs) were calculated to evaluate the toxicity of the substances. Both species showed similar sensitivities to all substances tested. Disinfectants (EC(50) = 1.78 and 1.79 mg/l for CH(2)O; EC(50) = 10.15 and 11.1 mg/l for NaClO) were found to be more toxic than antibiotics. AMOX, OTC, and ST caused <20 % of alterations, even at the highest concentrations tested. FLU was the most toxic to P. lividus (EC(50) = 31.0 mg/l) and SFD to A. lixula (EC(50) = 12.7 mg/l). The sea urchin bioassay should be considered within toxicity assessment-monitoring plans because of the sensitivity of larvae to disinfectants.
