Fig. 3.2.2 Influence of pH on the initial light intensity of euphausiid luminescence when the fluorescent compound F and protein P are mixed in 25 mM sodium phosphate buffers of various pH values, each containing 1M NaCl, at near 0°C. Both F and P were obtained from Meganyctiphanes norvegica. From Shimomura and Johnson, 1967, with permission from the American Chemical Society.

Mercury accumulation in viscera of euphausiids Meganyctiphanes norvegica) was decreased by moderate concentrations of selenium (10.0-1000.0 xg Se/L) in the medium. In studies with larvae of the Dungeness crab (Cancer magister), selenium concentrations of 10.0-1000.0 p,g/L tended to decrease mercury toxicity however, high levels of selenium (>5000.0 p-g/L) increased mercury toxicity.
