In this preliminary study, we assessed the toxicity of domestic bentonites using environmental toxicity testings of seed germination and bacterial bioluminescence. In cases of tested bulk bentonite samples, following ranges of toxicity were observed: -3 ~ 95% bioluminescence, 7.1 ~ 92.1% Lactuca germination. Similar results were also observed among tested other seeds, except seed Raphanus. No significant correlations between toxicity and metals contents of bentonite extractants were observed throughout this investigation. Interestingly, distinct different effects were observed according to bentonite colors (blue 67±8.7%, pink 27±10.4%, brown 58±14.5%).
Keywords bentonite, toxicity, bioluminescence, seed germination, food and drug
