[Experimental study of the bioaccumulation of inorganic mercury and methylmercury in the goldfish (Carassius auratus L.)].
The study of the mercury and methylmercury bioaccumulation by various species of fish is only possible experimentally when the animals are maintained fasting during a few days. With a such experimentation in the goldfish (Carassius auratus L.), the authors are showing that methylmercury is much more accumulated than inorganic mercury: the transfert factor is about 760 to 780 for the methylmercury chloride and only 90 for the mercuric chloride. In fact a lot of variables occur in this phenomena of bioaccumulation (experimentation time, size and age of fish, solvant space, concentration of oxygen and mercury in water,...) and make this study difficult.
