The biological effects of an anionic synthetic surfactant (ABS) and a non-ionic surfactant (Citowett) were evaluated using roots of onion bulbs (Allium cepa L.). Three parameters were studied: (1) root elongation, (2) the mitotic index, and (3) chromosome aberrations. The effects of increasing concentrations of surfactants were: (1) reduction in root length; (2) decrease in mitotic index and (3) induction of a high level of chromosome aberrations. The effects of ABS and Citowett suggest caution with regard to inappropriate use of these substances.

Abstract

The biological effects of an anionic synthetic surfactant (ABS) and a non-ionic surfactant (Citowett) were evaluated using roots of onion bulbs (Allium cepa L.). Three parameters were studied: (1) root elongation, (2) the mitotic index, and (3) chromosome aberrations. The effects of increasing concentrations of surfactants were: (1) reduction in root length; (2) decrease in mitotic index and (3) induction of a high level of chromosome aberrations. The effects of ABS and Citowett suggest caution with regard to inappropriate use of these substances.
