WebAug 31, 2015 · The rotifer LC50 was <0.1 ppm while the alga was not affected up to 5 ppm Cu(II). The low pH of the rotifer stomach may make it more sensitive to copper. However, when these cultures were combined, a copper concentration of 1.5 ppm was needed to inhibit the rotifer as the alga bound the copper, decreasing its bioavailability. WebThe result can be expressed as mass percentage, parts per million (ppm), or parts per billion (ppb): [Math Processing Error] (13.4.2) mass percentage = mass of solute mass of solution × 100 (13.4.3) parts per million (ppm) = mass of solute mass of solution × 10 6 (13.4.4) parts per billion (ppb) = mass of solute mass of solution × 10 9
