ABSTRACT
This article focuses on the effects of water-borne lead (Pb) on gill osmoregulatory function is of particular interest considering the widespread distribution of this heavy metal in natural waters, and evidence suggesting that Pb may preferentially accumulate in gill tissue. Nanomoles of inorganic phosphate tube were determined by linear regression analysis. Included in each assay were substrate blanks. The mean rate of sodium ion and potassium ion-stimulated ATP hydrolysis, as determined in three kinetic assays each conducted using gill homogenate from a single fish, is shown in the article.
