Environmental and anthropogenic drivers of soil pollution. Fundamentals and practical solutions
Conveners: Convener: Irena D. Atanassova
The session will cover aspects of soil pollution as a result of environmental and anthropogenic impacts. Climatic and anthropogenic disturbances on soils lead to significant changes in the mobility and transport of chemical elements and their ionic or complexed species, as well as various organic compounds both in their dissolved or adsorbed forms. The qualitative and quantitative assessment of contaminants and their species in soil is of key importance for clarifying the mechanisms of biogeochemical processes.
The session will aim at: assessing the properties and mechanisms of interaction of contaminants in soil; solubility and adsorption-desorption equilibria of contaminants with soil adsorbent under various conditions of climatic and anthropogenic changes; changes in chemical, physical and physico-chemical properties of soil adsorbent, as a result of anthropogenic and climatic impacts; pedogenesis of degraded soils and links with eco-chemical sources of organic matter and chemical elements; novel methods of analysis and spectral determination of molecular structure of labile and refractory soil organic matter and interactions with metal species in soil; humified, refractory and labile organic matter and links with contaminant mobilization in soils under changing climatic and anthropogenic conditions; solubility and bioavailability of inorganic and organic contaminants in degraded soils, metal species in soil solution as sensitive indicators of pedogenesis and anthropogenic disturbances, organo-chemical indicators of soil degradation, organic molecular markers and pollutants, role of microbial activity and links with organo-chemical markers and metal contaminant species; remediation techniques and effects on contaminant behavior and ecosystem services; conventional and emerging fertilisers and ameliorants affecting mineral nutrition of plants and contaminant mobilization; modeling the mobility of inorganic and organic contaminants in soils depending on soil characteristics.
The proposed session covers 6 of the conference themes, i.e.
1. Climate change: Mitigation and Adaptation
2. Water Resources: Quality and Quantity
3. Land Degradation and Restoration
4. Nature-based solutions
5. Fire in the earth system, effects and prevention
6. Ecosystem services and nature conservation
Under Climate change: Mitigation and Adaptation we will deal with molecular drivers and indicators, under Water Resources: Quality and Quantity we will focus on contaminants species and distribution, under Land Degradation and Restoration and Nature based solutions we will touch on soil characteristics and properties and remediation techniques; under Fire in the earth system, effects and prevention, we will assess effects on soil chemical and physico-chemical characteristics and contaminant behavior and under Ecosystem services and nature conservation we will stress upon effects of contaminant properties and reactions with soil components on ecosystem services and nature conservation.
This session will present recent research and practical applications targeting academic community, environmentalists, various end-users, e.g. policy makers, practitioners, farmers, industry, students, etc.
