• This study revealed similar harmful potential of studied compounds to nitrophenols. • No significant joint actions between the four studied compounds were observed. • The first toxicity data of guaiacol and its nitrated products are presented. • All studied compounds are considered harmful according to the European legislation. • This study revealed similar harmful potential of studied compounds to nitrophenols. • No significant joint actions between the four studied compounds were observed. • 1.

At a concentration higher than 3 mM, eugenol was cytotoxic to human oral mucous membrane cells, decreasing both cellular ATP and glutathione. However, at less than 1 mM, eugenol protected cells from the genetic attack of ROS, in part by inhibiting lipid peroxidation ( Jeng et al 1994a ). This study presents the first toxicological data of guaiacol and its nitro derivatives and reveals their harmful potential for the ecosystem. Applying V. fischeri bioluminescence acute toxicity test, EC50 values range from 16.7 to 103mgL-1 after a 30-min incubation period, which classifies all investigated compounds as 'harmful' according to the European legislation. GUAIACOL CARBONATE. Bis(2-methoxyphenyl) carbonate.

Pb-treated seedlings showed elevated levels of lipid peroxides with a concomitant increase in the activities of the enzymes superoxide dismutase (SOD ), guaiacol

Well kids my point is this, sure your intake of guaiacol isn't on the toxic level or you would be dead, however if you are pinning TNE every day Following the California wildfires of 2008, we developed sensitive methods for measuring free guaiacol and 4-methylguaiacol from pureed berries, juice and wine, 12 Apr 2013 No information available. Chronic Toxicity. Carcinogenicity. There are no known carcinogenic chemicals in this product. Page 4 / 7.

Causes skin irritation. Causes skin and eye irritation. Causes serious eye irritation. Harmful to aquatic life Oxidation of guaiacol is the rate-determining step for peroxidase activity. The specific activity of the control HRP enzyme was compared with the bioCNT-HRP complex, showing that the calculated specific activity of free HRP was ~ 1.46 μM/s (100%) and that of bioCNT-HRP was ~ 1.25 μM/s, which is approximately equal to 85% relative activity of the free enzyme concentration (Fig. 7A).
