It may potentially cause carcinogenic or teratogenic effects, although no scientific evidence showing either health effect has been found. Exposure routes of ethidium bromide are inhalation, ingestion, and skin absorption. The above studies do not support the commonly-held idea that ethidium bromide is a potent mutagen in humans, but they do indicate that it can be toxic at high concentrations. Recent science writers have reported on what is perceived to be disproportionate fear over the toxicity and mutagenicity of the compound.

This is unlike ethidium bromide, which is genotoxic at typical usage concentrations (0.5 µg/ml). Both dyes are cytotoxic, however, at commercially available stock concentrations. These data indicate that Diamond™ Nucleic Acid Dye is significantly less toxic than ethidium bromide within the typical concentrations used to stain gels. Ethidium bromide (EtBr) is one of the commonly used substances in molecular biology experiments. It is highly mutagenic and moderately toxic substance used in DNA-staining during electrophoresis. Interest in phytoremediation as a method to solve chemical contamination has been growing rapidly in recent years.

Its major advantage is that it is as sensitive as ethidium bromide but does not require UV light for visualization.
Se hela listan på sciencedirect.com Ethidium bromide is considered a toxic compound, since by inhalation it causes acute irritation of the respiratory tract. Also, by contact with the skin, ethidium bromide can cause inflammation and / or discoloration. Meanwhile, in the eyes acute exposure causes irritation, redness and eye pain.
