Abstract

The chlorine-base compounds (traded as solutions, gel, or tablets, widely used as disinfectants of surfaces, of clothes, or as a sanitizer, may be toxic for the environment, to some extent). This instantly affects the organisms in direct contact with the chlorine products, and the long term chronic effect may cause significant shifts to the impacted ecological niche. During this scientific study there were observed some test organisms, as a screening tool for the chlorine compounds from their environment. Both test species (Lemna sp. and Folsomia sp.) can be tested in the laboratory at low costs. This present study comprises preliminary results, that will be continued by a factorial analysis of other chlorine compounds concentrations and their impact reflected by the juvenile sprintailsț number, by the number of altered Lemna sp. fronds, and the root regrowth.
