Topics
With the analyses of C, N, H, and S stable isotopes (δ13C, δ18O, δ15N, δ2H, δ34S) in environmental samples, from soils to sediment and water we study:
– Effects of changing environmental conditions on the mechanisms and rates of C stabilization in soils
– Interactions between land degradation and C sequestration in soils
– Reconstruction of past environments and climates to improve future predictions
– Fate of organic pollutants in soils, sediments and water and interactions with organisms exposed to pollution
– Application of CSIA in forensic science
