The effect of hexavalent chromium ions on the photosynthesis and growth of the diatom Nitzschia palea and the green alga Chlorella pyrenoidosa has been studied and compared with the effect of Cu and Hg. The effect of chromium is very similar to that of Cu and Hg, but it is more than one hundred times less toxic for the algae than copper. The toxicity of chromium is not counteracted by adding Fe to the culture solution. The problems regarding cleaning glass‐ware in dichromate‐sulphuric acid are discussed and it is strongly recommended to use other cleaning agents.
