Abstract
Alkalinity has been found to be a lethal factor for trout in Arizona waters low in buffering agents. Lethal pH for trout in streams ranged upwards from 8.8, but some in lakes were able to withstand 10.2. Alkalinity results from aquatic vegetation removing CO2 with consequent breakdown of bicarbonates to form alkaline carbonates. Increasing water turbidity causes pH to drop, through cutting off light to plants, thus reducing photosynthesis.This publication has 0 references indexed in Scilit:
