Plśtz J., 1991. Effects of salinity and toxic heavy metals on oxygen release by Fucus vesiculosus L. Acta Ichthyol. Piscat. 21 (Suppl.): 283-290.

Continuous measurements with an oxygen electrode applied to thalloid algal material were used to determine 02 production/consumption at light and dark phases in an open system. The balance of photosynthesis-related 02 release by Fucus vesiculosus L. in seawater shows a decrease within only 20 min. after addition of Cu(II)SO4ּ5 H20 at condensations known to be toxic. Short response time and continuous recording allowed to show that in the case of ZnCl2 addition, the increase in 02 release is followed by a decrease. Effects of interactions between zinc and copper compounds and seawater salinities can be recorded in the same way.
