Boron toxicity in Lemna gibba
Total soluble phenols and total chlorophylls content, changes of biomass and concentration factor in Lemna gibbaexposed to different concentrations of boron were measured. Day six soluble phenols showed significant differencesin treatment with 10 mg/L of boron. At day ten, chlorophylls content in tr...

| Resumo: | Total soluble phenols and total chlorophylls content, changes of biomass and concentration factor in Lemna gibbaexposed to different concentrations of boron were measured. Day six soluble phenols showed significant differencesin treatment with 10 mg/L of boron. At day ten, chlorophylls content in treatment 2 mg/L concentration increasedrespect to other experimental groups and control group, there were no significant differences. Biomass of Lemnagibba decreased significant in treatments with 1.5 and 2.5 mg/L treatments of boron. The highest Bioconcentrationfactor was found in 0.25 mg/L of boron, this accumulation is not relevant. Lemna gibba showed tolerance in thepresence of boron in concentrations used here. Suggesting that this aquatic macrophyte could be used for tertiarytreatment and the possible renewal wastewater contaminated with boron. |
