Assessment of the risks of using linuron-based formulations on the growth, health and nutritional quality of Three vegetables –Phaseolus vulgaris, Solanum nigrum and Daucus carota- regularly grown in the market-gardening areas of Ngaoundéré-Cameroon

Abstract

The objective of this study was to evaluate the effect of the treatment of cultivated soils with linuron-based formulations on the growth parameters, on the nutritional and health quality of green bean, black nightshade and carrot fruits regularly developing in market gardening areas of Ngaoundéré-Cameroon. The methodology consisted in developing these plants regularly cultivated on contaminated soil pots at three concentrations of linuron of 0.93mg/L; 1.87mg/L; 3.74g/L and on uncontaminated potted soils. During their growth, the sizes and the fresh biomasses of the seedlings were evaluated. Then, the linuron residues were extracted from the samples of the consumable parts by the QUErchercs method and analyzed by HPLC-UV. With regard to nutritional quality, soil contamination by linuron-based formulations led to a significant decrease in vitamin C, polyphenol and antioxidant content in the edible parts of fruits and vegetables Assessment…..
