AbstractThe rare earth elements (REE) are vital to innovation technologies and society and are important for the industry, especially for high-tech solutions. In the modern world, anumerous applications have been developed using rare earth elements (REE), implying human exposures and raising unclear questions as to REE-associated health effects. Protecting the environment and public health from disadvantageous actions of rare earth elements mining and processing as emerging pollutants is urgently desired to achieve sustainable development. All activities in mining processes like extraction, separation and after recycling of REE elements could create rick to human health and environment. In the paper the role of management in safety aspects during mining and processing of rare earth elements has been highlighted. In the paper, the potential dangerous and damaging effects on the environment and human health have been identified - the potential risk in the processing as well as the possibilities of preventing the occurrence of hazards have been analyzed.

In the Valdichiana area (Tuscany, Italy) an ancient native landrace of elephant garlic (Allium ampeloprasum L.), locally known as “Aglione della Valdichiana”, has long been cultivated. The aim of this study was to check whether there are differences in the mineral and nutraceutical profiles of the Aglione della Valdichiana cultivated conventionally and organically. Based on the analysis by ICP-MS of a wide array of major, minor, essential, and non-essential trace elements as well as rare earth elements, and the evaluation of the content of polyphenols, flavonoids, antioxidants, soluble proteins, soluble sugars, and starch, as well as the weight and water content, it was concluded that differences in the mineral and nutraceutical profiles of organically and conventionally grown bulbs were very limited. Only a statistically (p < 0.05) higher concentration of Cd (+2620%), Co (+113%), Mn (+55%), Rb (+180%), and Sb (+180%), as well as glucose (+37%) in conventionally cultivated bulbs emerged. Cadmium was the only element slightly higher than in the “reference plant,” but with a negligible risk (three orders of magnitude lower) for human health based on consumption. It is concluded that we failed to find evidence of healthier food or a higher nutraceutical quality for organically cultivated elephant garlic.

In the context of restrictions due to the sanctions imposed, a key factor in the country's development is the development of new Russian high-tech materials and their production technologies. The study of ash and slag waste from the Kemerovo State District Power Plant was carried out in this work using the methods of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). It has been established that matrix elements make up the predominant share of ash and slag waste. Rare and rare earth elements in terms of their content are classified as trace elements, however, some of them either have commercial values, or are close to it.
