The aim of this study was to estimate the bioavailability of essential (Zn, Cu) and non-essential metals (Cd, Pb) to the earthworm Lumbricus rubellus exposed to soils originating from a gradient of metal pollution in Southern Poland. Metal uptake and elimination kinetics were determined and related to soils properties. Experimental results were compared with tissue metal concentrations observed...
Background and Objective: Pollutants emitted from industries can endanger human health if they enter the food chain, so environmental monitoring is essential. The aim of this study was to investigate the bioaccumulation of heavy metals including lead, copper and nickel and the level of air pollution tolerance index in Prosopis juliflora and Conocarpus erectus tree species during one-year period...
Many metals are very important for normal plant growth and development. One of these metals is zinc – typically the second most abundant transition metal in organisms and a substantial micronutrient that plays different roles in plant physiology. Zinc is an essential component of over 300 enzymes. It is responsible for gene regulation and stabilization of protein structure including Zn fingers,...
