Pike (Esox lucius L.) and Some Other Aquatic Organisms in Sweden as Indicators of Mercury Contamination in the Environment

“…It has been demonstrated experimentally that they accumulate mercury directly from the surrounding water (BoEthius 1960) as well as from food (Raeder und Snekvik 1941, Hannerz 1967. Mercury is present everywhere in nature, although mostly in minute amounts, as a consequence of the evaporation of mercury from the earth crust and its subsequent distribution by aerial circulation and precipitation (Stock and Cucuel 1934). Figures on mercury content in water and fish from 1930 to 1940 have been published, some of which are presented in Tab.…”

Mercury in the air and precipitation.

“…On the other hand, the mercury concentra tions in precipitation are also scattered (STOCK and CUCUEL, 1934;WEISS et al, 1971). Poly ethylene bottles are often used for water sample storage, and MATSUNAGA et al (1974) have found that nanogram amounts of mercury are given off from them during sample storage, which increases the initial mercury level by a factor of 2-100 times, even if the container has been acid-rinsed.…”

“…The concentration of atmospheric mercury has been measured by several investigators (STOCK and CUCUEL, 1934;WILLISTON, 1968;MCCARTHY et' al., 1969;LONG et al, 1973;SCARINGELLI et al, 1974;JOHNSON and BRAMAN;BRAMAN and JOHNSON, 1974; VAN DER SLOOT and D AS, 1974) and the reported values are scattered.…”

Metal Releases From Toxic Wastes and Their Impact on Groundwater and Surface Waters

“…Analyses of trace metals were first performed in marine waters (Stock and Cucuel, 1934) and on surface and subsurface waters in traditional mining areas (e.g.…”
