“…Foley et al (1978) and Lowe et al (1985) determined that environmental factors besides As concentrations in water column and prey items are important in explaining arsenic concentrations in fish tissues. Salinity, temperature and habitat type were also found to be correlated with the accumulation of As in marine fish species (Norin et al, 1985), while As accumulation in fish found in lakes was correlated with total nitrogen in the water, dissolved organic carbon, and percent of watershed dedicated to agriculture .…”

Contaminants in tilapia (Oreochromis mossambicus) from the Salton Sea, California, in relation to human health, piscivorous birds and fish meal production

A summary of all existing information collected since 1980 on contaminants in tilapia from the Salton Sea is presented and risks to humans and fish-eating birds assessed. Of the 17 trace elements, 42 organic pesticides and 48 polychlorinated biphenyls (PCBs) analyzed in tilapia whole body and fillet samples, only selenium (Se), arsenic (As) and possibly dichlorodiphenyltrichloroethane (DDE) were found at levels high enough to be of concern for fish, birds or humans. Average current concentration of arsenic (As) was 0.7 lg g -1 wet weight (ww) in whole body samples and 1.2 lg g -1 ww in fillet samples, or 2.8 and 5.7 lg g -1 dry weight (dw), respectively. Inorganic As averaged 0.006 lg g -1 ww (0.03 lg g -1 dw) in fillet samples, which represented 0.3% of total As.

“…When these wastes react with runoff, surface and rain waters, they can damage ecosystems as As can be transferred to the dissolved fraction. For example, studies on fish collected in a mining area ([Foley et al, 1978], [Orsini et al, 1994], [Casiot et al, 2009] and [Vicente-Martorell et al, 2009]) revealed As concentrations higher than the quality standards (maximum As concentration in whole fish <1 mg kg −1 wet weight according to WHO, 2001). On the other hand, natural attenuation processes can occur and dissolved As is frequently trapped by coprecipitation/sorption reactions with Fe, Mn and Al-oxyhydroxides, complexed with humic substances and/or immobilized by microbial activities ([Hoins et al, 1993], [Ali and Dzombak, 1996] and [Morin and Calas, 2006]).…”

International audienceAt a watershed scale, sediments and soil weathering exerts a control on solid and dissolved transport of trace elements in surface waters and it can be considered as a source of pollution. The studied subwatershed (1.5 km2) was located on an As geochemical anomaly. The studied soil profile showed a significant decrease of As content from 1500 mg.kg-1 in the 135-165 cm deepest soil layer to 385 mg.kg-1 in the upper 0-5 cm soil layer. Directly in the stream, suspended matter and the <63 μm fraction of bed sediments had As concentrations greater than 400 mg.kg-1. In all these solid fractions, the main representative As-bearing phases were determined at two different observation scales: bulk analyses using X-ray absorption structure spectroscopy (XAS) and microanalyses using scanning electron microscope (SEM) and associated electron probe microanalyses (EPMA), as well as micro-Raman spectroscopy and synchrotron-based micro-scanning X-ray diffraction (μSXRD) characterization. Three main As-bearing phases were identified: (i) arsenates (mostly pharmacosiderite), the most concentrated phases As in both the coherent weathered bedrock and the 135-165 cm soil layer but not observed in the river solid fraction, (ii) Fe-oxyhydroxides with in situ As content up to 15.4 wt.% in the deepest soil layer, and (iii) aluminosilicates, the least concentrated As carriers. The mineralogical evolution of As-bearing phases in the soil profile, coupled with the decrease of bulk As content, may be related to pedogenesis processes, suggesting an evolution of arsenates into As-rich Fe-oxyhydroxides. Therefore, weathering and mineralogical evolution of these As-rich phases may release As to surface waters

“…Several forms of arsenic, such as arsenite and arsines, are known to be toxic to a variety of organisms (Ferguson & Gavis, 1972) and are possibly carcinogenic (Neubauer, 1947). Sodium arsenite is used in aquatic systems as a herbicide, while organic arsenicals are used as herbicides and insecticides in a wide variety of agricultural applications and may be extremely persistent (Foley et al 1978;Ferguson & Gavis, 1972). Although high levels of arsenite are occasionally present in fresh water samples (Klumpp & Peterson, 1979)5 the majority of arsenic in seawater is in the relatively harmless form of arsenate (Andreae, 1978) and is thus not considered such a potentially hazardous element as mercury, cadmium or lead.…”

Arsenic concentrations in estuarine sediments from England and Wales range over three orders of magnitude. The highest concentrations, up to 2500 figjg, occur in the sediments of estuaries in south west England associated with past or present metalliferous mining activity. Strong correlations exist between arsenic and iron in 1 N-HC1 extracts of different estuarine sediments. The As/Fe ratio in those estuaries not contaminated with mine wastes is n x 10 ~4, increasing to 190 x 10 ~4 in metalliferous sediments.The highest arsenic concentrations in organisms, almost 200 /igjg, are found at those sites in estuaries where high As/Fe ratios exist in the sediment. Concentrations of arsenic in estuarine organisms correlate more significantly with the As/Fe ratio in sediments than arsenic levels alone. This is most evident in the bivalve Scrobicularia plana (da Costa) where the proportion of readily extractable (1 N-HC1) Fe ir. sediments mediates the availability of As in a predictable way. Other factors, important in the selection of Scrobicularia as an indicator of available arsenic in sediments, such as tissue distribution and the effect of size/age on arsenic content, are discussed.
