Class Soil Pollution

  • Presentation


    Acquire basic knowledge on the problem of chemical and physical soil degradation, on the processes of water and wind erosion in soil degradation / removal.

    Understand the concepts of contamination and pollution. Type and dynamics (mobility) of the different pollutants (organic and inorganic) in the soil and their interaction with adjacent systems (atmosphere, hydrosphere and biosphere).

    Understand the criteria for assessing and monitoring soil pollution.

    Understand strategies and learn available technologies for soil remediation.

    Sensitize the student to the international and national reality, regarding soil pollution, addressing whenever possible real practical examples.

    Promote student contact, through practical exercises and field trips, with examples of pollution in Portuguese territory, promoting a closer relationship between the student and the national reality.

    Contamination exercises. Surface and depth distribution of contamination. Pollutant sources and movement.

    Thematic work (pre-defined) on soil pollution with presentation (oral and / or written).

    Work on case studies (technical output or other topic of choice) with final presentation (poster / oral / written presentation).

  • Objectives


    The student must be able to understand and recognize the evidence of the processes of chemical and physical degradation of the soil.

    Understand the erosivity and erodibility factors that participate in soil water and wind erosion and understand the impacts of these processes. To know the different methods for determining water erosion.

    Be able to understand the concept of pollution, identify the type and dynamics (mobility) of different soil pollutants and their interaction with adjacent systems (atmosphere, hydrosphere and biosphere).

    Understand what is meant by soil quality assessment, and the various stages of this process.

    Know several remediation techniques (strategies and technologies) and understand their application, their advantages and disadvantages.

    Know the national and international legislation applicable to the situations identified in Portugal.

    Learn to work with spreadsheets (excel) and Google Earth.

    Being able to work in a team.

  • Teaching methodologies and assessment

    Teaching methodologies and assessment

    The methodology used consists of the active method, placing the student at the centre of the learning process. Classes use a combined expository/interrogative method, using active learning methodologies: brainstorming, role play, etc. Case study analyses are included in the topics covered, encouraging peer discussion and problem-solving. This process will allow students to develop critical thinking, increasing their problem-solving skills. The following methodologies can be used: inverted classes, peer teaching and peer feedback. A possible field trip to observe and collect samples (technical trip) will allow for non-formal learning.
