FITOAKUMULACJA MOLIBDENU I MANGANU W KONICZYNIE BIAŁORÓŻOWEJ (TRIFOLIUM HYBRIDUM L.) I BABCE POSPOLITEJ (PLANTAGO MAJOR L.)

Abstract

THE FITOACCUMULATION OF MOLYBDENUM AND MANGANESE IN ALSIKE CLOVER (TRIFOLIUM HYBRIDUM L.) AND GREATER PLANTAIN (PLANTAGO MAJOR L.)Abstract. Studies of molybdenum and manganese content in topsoil and plants were carried out in the Eastern Beskids (Carpathians) in area of occurrence of menilite shales and the Otryt sandstones. The aim of the study was to evaluate the content of molybdenum and manganese in plants and the determination of a bioaccumulation of these two chemical elements in two species of plants (Trifolium hybridum L. and Plantago major L.). Mo symbols were performed by means of ICP-MS method, and Mn were analyzed by means of ICP-OES method. Result of studies in the Trifolium hybridum L. have shown higher content of Mo in the area of occurence of menilite shales (in leaves – 14 mg/kg) than in the Otryt sandstones (in leaves – 0.30 mg/kg). Most Mn accumulates in leaves (86–257 mg/kg). The bioaccumulate indicator of Mo in individual plant species is different and ranges from 0.13 to 1.13. The highest rate of bioaccumulation of molybdenum (1.13) can be observed in Trifolium hybridum L., which inhabits areas of menilite shales.
