Toxicity of wood leachate to algae Desmodesmus subspicatus and plant Lemna minor

Wood is one of the extensively used goods on the earth due to its large accessibility and usage in a wide range of human life. When woods are exposed to aquatic media, leachates are generated which may affect the quality of water and damage aquatic life into which they are discharged. This research...

description Wood is one of the extensively used goods on the earth due to its large accessibility and usage in a wide range of human life. When woods are exposed to aquatic media, leachates are generated which may affect the quality of water and damage aquatic life into which they are discharged. This research seeks to evaluate the toxicity of linden ( Tilia cordata ), larch ( Larix decidua ) from the Czech Republic, cedrela ( Cedrela odorata ) and emire ( Terminalia ivorensis ) from Ghana wood leachates to two aquatic organisms ( Desmodesmus subspicatus and Lemna minor ). In algal and duckweed toxicity tests, these plants were exposed to different concentrations of wood leachate with nutrient medium creating concentration rates, 20, 30, 45, 67, and 100% v/v. High concentration of phenols and heavy metals may have contributed to toxicity. It was observed that the various wood leachates were inhibitory to the growth rate of algae and duckweed with emire exhibiting the highest toxicity with IC 50 of 30.04% and 28.58% and larch the lowest toxicity with IC 50 of 51.18% and 49.57% in relation to growth rate and chlorophyll respectively, hence indicating confirmed and potential toxicity of the various wood leachates to the aquatic organisms.
