AbstractLead is unique among the toxic air contaminants that the World Health Organization (WHO) has identified it in several ways. Lead concentration is increasing rapidly in the environment due to increased use in anthropic activity. Lead is released into the atmosphere from metallurgy and siderurgy industry, during coal burning, oil or wastes, from power plants which use solid fuel, from traffic and the building sites. Regardless the exposure mode, the presence of lead in urban air, even in r...

In this paper a two stage bench scale leaching procedure is used to assess the heavy metals release from a wood-based fly ash of a 5.0 MWth grate-fired boiler. In the first step mostly K was leached with water. In the subsequent acid leaching step heavy metals were leached at a pH of 3. The remaining solids were agglomerated together with the bottom ash and the dried K-concentrate from the first leaching step whereas the filtrate was treated before discharge. In the agglomerates produced the ...

The release of metals from many industrial processes into aquatic ecosystems is currently a major environmental threat, especially in developing and emerging countries. Most traditional treatment approaches are not efficient in terms of removal yield and cost. Plants have the ability to stabilize metals in a fast and cost-efficient way. In this context, aquatic plants are successfully applied for remediation of hazardous elements from industrial wastewater. This study demonstrates the capabil...

In the eastern part of Romania, there are a lot of reservoirs of water whose age exceeds 30-40 years. They were built taking into account the existing norms and the specific environmental conditions at that time. Over time, there have been numerous changes in the parameters that define how these water reservoirs are exploited, which have questioned their safety in operation. The deforestation that has taken place over the last 30 years in Romania and the climate change have led to the emerge...

Iodine is an essential microelement required by humans and animals. Leaching of soils under intensive rains has threatened the fertility status of iodine in soils. Therefore, four discrete amendments were used for the mitigation of iodine leaching from soils. For this study, soils collected from four land uses were mixed with the amendments (gypsum, lime, fly ash, charcoal and sawdust) at the rate of 0, 2.5% and 5% (w/w) in PVC columns. Potassium iodide (KI) was applied to the soil at rate of 10...

The goal 12 of the 2030 Agenda for Sustainable Development takes into consideration the responsible consumption and production in the perspective of circular economy. The agri-food sector is more actively involved in these initiatives, because it offers the possibility to exploit waste and by-products, by adopting suitable biotechnologies. Such processes can be carried out either under aerobic conditions, for the production of compost, or anaerobically, for the production of biogas. In this work...

Digestate derived from the anaerobic digestion of biowaste is a nutrient-rich substance whose direct use on land is not permitted by the Italian Legislation. The possibility of recovering its nutrients can be given by the processes of stabilisation and sanitation required by the Italian Legislation. Among these processes, composting and calcium hydrolysis with neutralization (CHN) permit to obtain useful soil improvers like compost and defecation gypsum (DG). In this paper a gate-to-gate Life Cy...

Deforestation and changes in forest cover are subject to the effects of many factors: economic, social, cultural, political, and environmental and their interactions. To assess these factors, one should necessarily know their nature and then model them. Nowadays many models have been introduced to explore deforestation, however most of them are based on past events and do not pay enough attention to socioeconomic factors. Moreover, considering the future is sometimes absent in those models. The ...

This study shows the impact of tree- and forest-level variables on epiphytic lichens within four managed forest fragments. Additionally, the impact of human activities, such as pastoral activities and timber harvesting, on epiphytic lichens is taken into account. At the tree level, a pertinent ecological pattern with regard to lichen abundance could not be supported by the obtained results because the effect of tree and forest variables (aspect and shrub cover) was significant only on a few lich...

Current landscapes have been intensively modified by humans and forest fragmentation has created substantial increases of forest edges. So far, scale-dependence between observable ecological patterns and the underlying processes affected by forest fragmentation have been widely ignored. To overcome the widespread ambiguity in selecting relevant spatial scales for studying the ecological effects of forest fragmentation, we investigated the effect of forest prevalence and edge length on carbon st...
