“…Selenium forms complexes with copper (Amdur et al, 1991), arsenic (Levander, 1977), cadmium (Van Puymbroeck et al, 1982), and mercury (Southworth et al, 1994) that can reduce the toxicity of selenium. Antagonism has also been observed between aqueous selenium (as selenite) and mercury (#2) in northern creek chubs (Kim et al, 1977) and in other "sh species (Turner and Swick, 1983;Cuvin and Furness, 1988). Stingy Run and Little Scary Creek had elevated water levels of arsenic, chromium, nickel, and selenium and "sh livers had elevated levels of arsenic, copper, and selenium.…”

“…Mercury was analyzed because of its potential ecosystem and human health effects, and because recreational fishers were anxious to learn about a potential risk from mercury. Selenium was analyzed because of its reported protective effects against mercury toxicity (Ganther et al, 1972; Kim et al, 1977; Ringdal and Julshamn, 1985; Satoh et al, 1985). We examined whether New Jersey’s legal size limits for striped bass fishing, imposed an exposure burden on people who consume legal-sized fish.…”

We examined total mercury and selenium levels in muscle of striped bass (Morone saxatilis) collected from 2005 to 2008 from coastal New Jersey. Of primary interest was whether there were differences in mercury and selenium levels as a function of size and location, and whether the legal size limits increased the exposure of bass consumers to mercury. We obtained samples mainly from recreational anglers, but also by seine and trawl. For the entire sample (n = 178 individual fish), the mean (± standard error) for total mercury was 0.39 ± 0.02 μg/g (= 0.39 ppm, wet weight basis) with a maximum of 1.3 μg/g (= 1.3 ppm wet weight). Mean selenium level was 0.30 ± 0.01 μg/g (w/w) with a maximum of 0.9 μg/g). Angler-caught fish (n = 122) were constrained by legal size limits to exceed 61 cm (24 in.) and averaged 72.6 ± 1.3 cm long; total mercury averaged 0.48 ± 0.021 μg/g and selenium averaged 0.29 ± 0.01 μg/g. For comparable sizes, angler-caught fish had significantly higher mercury levels (0.3 vs 0.21 μg/g) than trawled fish. In both the total and angler-only samples, mercury was strongly correlated with length (Kendall tau = 0.37; p < 0.0001) and weight (0.38; p < 0.0001), but was not correlated with condition or with selenium. In the whole sample and all subsamples, total length yielded the highest r2 (up to 0.42) of any variable for both mercury and selenium concentrations. Trawled fish from Long Branch in August and Sandy Hook in October were the same size (68.9 vs 70.1 cm) and had the same mercury concentrations (0.22 vs 0.21 ppm), but different selenium levels (0.11 vs 0.28 ppm). The seined fish (all from Delaware Bay) had the same mercury concentration as the trawled fish from the Atlantic coast despite being smaller. Angler-caught fish from the North (Sandy Hook) were larger but had significantly lower mercury than fish from the South (mainly Cape May). Selenium levels were high in small fish, low in medium-sized fish, and increased again in larger fish, but overall selenium was correlated with length (tau = 0.14; p = 0.006) and weight (tau = 0.27; p < 0.0001). Length-squared contributed significantly to selenium models, reflecting the non-linear relationship. Inter-year differences were explained partly by differences in sizes. The selenium:mercury molar ratio was below 1:1 in 20% of the fish and 25% of the angler-caught fish. Frequent consumption of large striped bass can result in exposure above the EPA’s reference dose, a problem particularly for fetal development.

“…Onion and garlic are known to contain selenium which interferes in the Hg metabolism suppressing Hg accumulation (WHO Food additives series: 44). Selenium oxide is an effective antagonist to the toxic effects of mercuric chloride in fish (Kim et al, 1977). Selenium has been shown to counteract the toxicity of methyl-Hg in many systems (Whanger, 1992), including neuron cultures.…”

Epidemiological study of clinical signs and symptoms of mercury poisoning in fish consumers residing in five villages along Thane Creek and Ulhas River Estuary near Mumbai, India

The fish of Thane Creek and Ulhas River Estuary are contaminated with mercury. The traditional fishing folks residing along these water sources consume large amounts of these fish for their sustenance, therefore, being vulnerable to mercury poisoning. A survey on the clinical signs and symptoms of mercury poisoning was carried out in Wehele, Alimgarh and Diwe-Kewni along Ulhas River Estuary and Vittawa and Airoli along Thane creek. Fortunately, no alarming signals of mercury poisoning could be detected in these populations. Genetic make-up and/or use of onion and garlic in the fish preparations could be the probable detoxifying factors in these populations. However, these populations being vulnerable to mercury poisoning, continuous monitoring is recommended in these areas.
