Investigation of Some Organic Pollutants Impact on Physico-Chemical Characteristics of Plantlets

Abstract

The cleaning process plays an important role in industry. On the other hand, the presence of detergents in soil can greatly impact on the environment. Therefore, the present study was conducted to evaluate the impact of two complex pollutants on some plantlets, e.g. Phaseolus vulgaris and Petroselinum crispum. In this context, this article uses various physico-chemical methods to compare the impact of non-biodegradable liquid detergent (a mixture of different compounds which contain isothiazolinone, methylisothiazolinone and 2-bromo-2-nitropropane-1,3-diol) on the environment with the one based on biodegradable origin (without 2-bromo-2-nitropropane-1,3-diol). Moreover, additional investigations showed the significant decrease in total carotenoids content and colour parameters with pollutant concentrations (0.125÷0.5%). Based on the results from the analysis performed in this paper, the contamination of soil with liquid detergents can have adverse effects on plants metabolism with plantlets height and number of leaves variation. Although there is no very strict correlation between the biometrical parameters and the concentration of the detergents used in this study, as a result of the individual enzymatic response of the plantlets to the aggression of the detergents, it is obvious that the plantlets’ metabolism is negatively influenced by the presence of both detergents. Also, the content of carotenoids and xanthophylls decreased in the case of studied samples, at the highest concentration (0.5%) of non-biodegradable detergent (Phaseolus vulgaris samples) and lower concentration (0.125%) of biodegradable detergent (Petroselinum crispum samples).
