Inhibition Effect on the Allium cepa L. Root Growth When Using Hexavalent Chromium-Doped River Waters

Abstract

The effect of Cr6+ on Allium cepa root length was studied using both clean and polluted river waters. Seven series of Cr6+-doped polluted and non-polluted river waters were used to grow onions. Chromium concentration (Cr6+) of 4.2 mg L−1(EC50 value), doped in clean river water caused a 50% reduction of root length, while in organically polluted samples similar root growth inhibition occurred at 12.0 mg Cr6+ L−1. The results suggested that there was a dislocation to higher values in toxic chromium concentration in polluted river water due to the eutrophization level of river water.
