This study provides characterizations and comparisons of leachates produced from 29 tree species in order to investigate the environmental impacts of leachates from different species and layers of trees. Analysis included COD, TDN, DOC, UV-visible and fluorescence spectroscopy, UV irradiation, and polyphenolic content. As confirmed by this research, bark produced leachate with higher concentrations of organic carbon, nitrogen, polyphenols, and condensed tannins. Hardwood leachate produced more humic-like material while softwood leachate produced more tryptophan-like material. Species found posing higher environmental risks included the Ash, Olive, Poplar, and Chestnut trees. Further investigation is recommended to reduce the impact of lumber leachate on aquatic ecosystems.
