This sub-line is divided into three sub-lines:
- Absorption and mobilisation in water of different types of inorganic and organic pollutants
The group BV1 has a wide experience in the study of absorption and mobilisation in water of different types of inorganic and organic pollutants mainly originated in phytosanitary treatments and in the incorporation of wastes as soil conditioners.
It is noteworthy the advances made in the study of the effects of various wastes valuing as soil conditioners: forest residues (barks), and from aquaculture (mussel shells) on the physical-chemical and biological properties of soils, especially the improvement of its qualities in the retention and immobilization of pollutants.
- Particulate conveying in infiltrated water
Other study line of the BV1 group is the particulate conveying in infiltrated water combining computed tomography and transport modelling in order to understand the influence of the soil structure in the particle matter behaviour. This line is developed in collaboration with researchers from Denmark, England and France, and is reinforced in the cluster with the chemical modelling and computational calculation capacities of the groups QO3 and LIA2.
- Hg and metil-Hg accumulation and mobility in soils and sediments
Another topic of interest which is being developed within this line by the BV1 is the study of Hg and metil-Hg accumulation and mobility in soils and sediments, as well as the role of vegetation in the transference of atmospheric Hg to soil. This aspect will be studied in the context of the components functions in the terrestrial ecosystems as Hg sewers at a global level in contexts influenced by the climate change and the reduction of anthropogenic Hg emissions to the atmosphere promoted by the Minamata Convention.
