Накратко на български

Замърсените от човека почви се анализират чрез наблюдение на безгръбначни животни при различни температури и нива на CO2. Това помага да се разбере как глобалното затопляне и засушаването повишават токсичността на почвите, особено при киселинна среда.

Toxicity of anthropogenic multi-stressed soils under a global warming perspective

Global climate change is displayed as a set of stressors potentially impairing the biotic and abiotic components of terrestrial ecosystems. This situation may worsen in environments degraded by anthropogenic activities where soil biota has to deal with already multiple stressors, and the toxicity of the contaminants present may change depending on the prevailing climate conditions. The general objective of GLOBALTOX was to assess how the toxicity of anthropogenic multi-stressed soils may be affected under the current global warming perspective, using soil invertebrates as bioindicators along with soil physico-chemical and microbiological parameters. The specific objectives were: 1) to assess the sensitivity of different invertebrate species to toxicity changes in anthropogenic multi-stressed soils induced by single climate factors (air temperature, soil moisture content, atmospheric CO2 concentrations, and UV radiation) and its relation to changes in soil physico-chemical and microbiological parameters; 2) to assess how the toxicity of anthropogenic multi-stressed soils may be affected under different climate scenarios simulated by climate factors combinations (air temperature, soil moisture content, atmospheric CO2 concentrations, and UV radiation), using soil invertebrates as bioindicators. Increasing toxicity risks of soils degraded by anthropogenic metal contamination were found under forecasted climate conditions for the year 2100, especially when soil dryness was intensified by elevated air temperatures. Worst scenarios were found for soils with acidic conditions and high metal(loid) availability.

Цел на проекта

Concept: Global climate change is displayed as a set of stressors (increasing temperature and CO2 levels, decreasing soil moisture content, higher UV radiation exposure) potentially impairing both biotic and abiotic ecosystem components. This may worsen in environments degraded by human activities where organisms have to deal with multiple stress factors, i.e. in multi-stressed environments, and the toxicity of the contaminants present may change depending on climate conditions. GLOBALTOX aims at assessing how the toxicity of anthropogenic multi-stressed soils may be affected under the current global warming perspective, using soil invertebrates as bioindicators along with soil physicochemical and microbiological parameters.Methodology: An inter/multidisciplinary ecotoxicological approach will be applied to soils from different environments with high human pressure (metal mining and agricultural areas), different soil invertebrate species (collembolans and enchytraeids) and single and multiple combinations of different climate factors (air temperature, soil moisture content, atmospheric CO2 concentrations and UV radiation). Climate factor combinations will be based on the emission scenarios predicted by the IPCC by the year 2100. For a complete overview of the problem, the project will rely on changes in key soil parameters (pH, organic matter, nutrient cycling, microbial community) and soil invertebrates (body metal concentrations, enzymatic biomarkers, DNA-damage, gene expression) to understand the effects at organism/population level (survival and reproduction).Impact: The foreground derived from the project will improve the environmental risk assessment of anthropogenic-degraded areas under future scenarios of climate change. GLOBALTOX will promote the social perception and awareness of anthropogenic contamination under a global warming perspective and the suitability of using soil invertebrates as bioindicators of toxicity changes.
