ACUMULATION PROPERTIES AND FOLIAR LIMB EFFECTS OF TETRACYCLINE AND METABOLITES IN LACTUCA SATIVA L., ERUCA SATIVA L. AND SPINACIA OLERACEA L.
Journal Title: Natural Resources and Sustainable Development - Year 2015, Vol 5, Issue 1
Abstract
The main goal of this study is to study the tetracycline and metabolites (TCS) accumulation properties in three vegetable plants leafs (lettuce, arugula and spinach). Residues of TCS, used in veterinary and human medicine, end up in crops due to the agricultural farmlands where manure application is used. The studied vegetables were grown hydroponically in greenhouses, using controlled nutrient solution containing 21.00 μg.L-1 TCS (quantity from the literature). Mature plants leafs were chemically characterized (water and cations), TCS measured using ELISA screening method (enzyme-linked immunosorbent assay) and foliar limb in terms of anatomical structure studied. Tetracycline was accumulated in the studied vegetables plants leafs in low concentrations (10-15 μg.kg-1), the accumulation rate depending on the plant characteristics. Normal aspect of foliar limb structure was highlighted in leaves of the studied plants, so the TCS accumulation does not lead to leaf structure alterations.
