Mutagenicity studies on terbacil, an uracil-analogue pesticide.

The possible mutagenic effect of the uracil analogue pesticide Terbacil was examined on Drosophila melanogaster and in mammalian cell culture. Terbacil did not prove to be mutagenic in the sex-linked recessive lethal mutation test, and it did not cause an increase in sister chromatid exchange in CHO cells. It cannot be considered a chromosome-mutagenic compound. Considering the procaryote studies known from the literature, it is assumed that Terbacil does not represent a genotoxic hazard for the persons involved either in its production or its use.
