Abstract
This article reports an environmental study concerning the liquid detergent contamination and its impact on some plantlets, e.g. Phaseolus vulgaris and Petroselinum crispum. In this context, this study focuses on specific modifications of the physical-chemical and biochemical characteristics of some plantlets induced by liquid detergents present in the soil, both bio-based and without environmental compatibility. The results of this study showed that a decrease (over 60%) in total chlorophyll per fresh weight could be solely due to the presence of non-biodegradable liquid detergents in soil, in various concentrations: 0.125%, 0.25% and 0.5% (wt/wt), calculated on water mass. On the other hand, the action of the detergents on the plantlets has revealed a decrease in the catalase activity in the case of both types of detergents.
