Ensuring food safety requires effective contaminant monitoring in fruits. This study compares two methods used to measure the concentrations of Cu, Zn, Ni, Pb, and Cd in plums from conventional and ecological orchards. Results indicate that microwave-assisted digestion provides greater accuracy and efficiency than conventional methods, reducing contamination risks and improving metal recovery.
Studies conducted at “Ion Ionescu de la Brad” University of Life Sciences in Iași confirm that the analyzed plums meet international food safety standards set by FAO/WHO. Detected levels were low, with essential metals such as Cu and Zn found in optimal concentrations.
These findings highlight the importance of advanced analytical methods in assessing food quality and safety and contribute to the development of more precise standards for monitoring heavy metals in agricultural production.
Erythrina lysistemon, commonly known as the South African coral tree, is an ornamental species valued for its ecological, agricultural, and medicinal benefits. However, its seeds often exhibit physical dormancy due to an impermeable seed coat, preventing germination even under favorable conditions. This study evaluates the effectiveness of two primary methods – mechanical scarification and soaking treatments- on freshly collected seeds and those stored for 12 months.
