title: Effects of mercury on ion and osmoregulation in the shore crab Carcinus maenas (L.).
abstract: The effects of lethal mercury concentrations on regulation of hemolymph electrolytes in the shore crab Carcinus maenas were investigated. In most experiments mercury exposure reduced hemolymph osmolality and Na+, Cl- and K+ levels to 55-90% of controls in 48 hr. Mercury exposure augmented calcium levels to 120-300% of controls. The effect of mercury on all of the electrolytes varied during the year, especially on magnesium levels which showed significant increases or decreases, or remained unaffected in different experiments.
