Toxicology and Immunotoxicology of Mercury: A Comparative Review in Fish and Humans

“…Ultimately, inorganic Hg is excreted in mammals primarily through urine, bile, feces, glands (e.g., sweat, lacrimal, mammary, salivary), and hair (Berlin, 1986;Berlin & Kacew, 1997;Harnly et al, 1997;Kacew, 2000;O'Flaherty, 1998). The biological residence time for Hg is affected by urinary, biliary, pancreatic, and intestinal excretion rates (Gerhardsson & Skerfving, 1996).…”

“…Anthropogenic sources of inorganic Hg exposure include soil, dust, and vapor from smelting; dental amalgams; industrial emissions (boilers, incinerators, combustors); mining; electrical sources; atmospheric transport; paints; and a variety of occupations (Harnly et al, 1997;McGroddy & Chapman, 1997;Hanisch, 1998). Mercury has been used for the following purposes: (1) catalysts in the chloralkali industry; (2) preservative s and pigments in the paint industry; (3) manufacture of pesticides (e.g., mercuric and mercurous chloride, phenylmercury acetate, and methoxyethylmercury compounds); (4) manufacture of pulp and paper; (5) battery production; and (6) therapeutic and ethnic folk medicines.…”

Mercury Accumulation in Harbour Seals from the Northeastern Pacific Ocean: The Role of Transplacental Transfer, Lactation, Age and Location

“…Finally, the delay between uptake of THg from the diet into circulating blood and its manifestation in the whisker has to be taken into account. In humans and mice, there is an average lag time of 10 days before circulating Hg in blood can be detected in hair (Cernichiari et al 1995;Harnly et al 1997;Zareba et al 2007). With these assumptions in mind, the THg signal obtained from the cut whiskers is representative of THg accumulation that started *4 months before sampling and ended *20-25 days before sampling (referred to hereafter as t = 0, the start of the THg temporal record).…”
