Open-pit coal mining causes land and soil degradation negatively affects properties. It is of great importance to determine variabilities in properties the abandoned area after mine closed bring it back nature by implementing appropriate rehabilitation programs. The aim this study was evaluate plant nutrient availability toxic element pollution an site. results indicated that amounts plant-avai...
Recovering and recycling phosphorus (P) from sewage sludge ash (SSA) for the purpose of P fertilizer production contributes to reducing input mined phosphate-minerals closing cycle. However, direct use SSA as is often a questionable strategy due its low nutrient efficiency. In addition, environmental risk potential utilizing in agriculture still unclear, particular toxic element (PTE) contamina...
The speciation of potentially toxic elements (PTE) in bottom ashes from municipal solid waste incineration (MSWI) and their relationship with grain size is investigated. proposed enrichment several potential lower sized grains discussed, comparing the literature new data on Parma’s incinerator. Results X-ray fluorescence spectrometry (XRF), SEM-EDS, XRD analyses different show (1) a positive Si...
The concentrations of both essential nutrients and chemically similar toxic analogues accumulated in cereal grains have a major impact on the nutritional quality and safety of crops. Naturally occurring genetic diversity can be exploited for the breeding of improved varieties through introgression lines (ILs). In this study, multi-element analysis was conducted on vegetative leaves, senesced fl...
A large proportion of the world’s population relies on medicines from the herbal sources. In this review, data about the mineral element content of medicinal and aromatic plants, including major elements, trace elements and toxic heavy metals, will be discussed and compared. Plants and drugs with remarkable elemental compositions will be pointed out. The main focus will be given on plants used ...
Heavy metals, such as, cadmium, zinc, Strontium and Arsenic have different chemical and physical properties. Also, each metal has its specific toxicological effects; in general, the contamination caused by heavy metals can have different effects in a human health. It is worth to summarize the effect of each element on human health. Scientific literature shows that cadmium affects the cardiovasc...
