Variations in concentration of total phosphorus in surface waters of dif¬ferent trophicity are discussed. Forms distinguished were: total particulate phosphorus in particles of size >150 ?m, and 65%). Concentrations of particulate phosphorus in different size fractions are additional indicators of the level of productivity of waters.
