NPLK14021U Soil and Water Pollution, Concepts and Theory
MSc Programme in Nature Management
MSc Programme in Agriculture
Review of composition and properties of soils and natural waters critical for pollutant fate and effects. Environmental microbiology: terrestrial and aquatic microbial lifestyles emphasizing microbial degrader populations. Reviews of methods for characterization of abiotic and microbial status of soils and natural waters.
Overview of pollutants in soil and aqueous environments
with emphasis on their physical-chemical, and microbiological
properties. Sources/sinks, monitoring systems and data
and mass balances of pollutants including heavy metals,
radionuclides, acids, pesticides, endocrine disruptors, detergents,
PAH’s, halogenated compounds, veterinary drugs/biomedicine, natural
toxins, anthropogenic nanoparticles, radionuclides, and
microbial pathogens. Solubility, complexation and speciation of
toxic inorganic compounds in soils and natural waters. Pollutant
binding processes including ion exchange, surface complexation, and
partitioning into organic matter and living media
(bioconcentration, biomagnification). Reactions at particle
surfaces including surface catalysis and immobilization. Hydrolysis
and photochemical degradation. Redox processes, zonations and
sequences. Microbial/enzymatic degradation and mineralization
pathways, metabolite formation, and transformation kinetics.
Software for QSAR estimation of pollutant properties, and for
computing speciation and binding (MINTEQ).
Biodegradation and toxicity, microbe-metal interactions, metal toxicity and resistance; xenogenetic pollutants and antibiotic resistance.
Outlook: Emerging pollutants, genes and microorganisms
The objectives of the course are to comprehend and to study how: i) soils and natural waters are affected by pollution, ii) soils function as “filters” for natural attenuation of pollutants, iii) pollutants bind and transform, and iv) how we quantify the chemical and microbial processes.
After completion you should be able to:
- Classify and provide overview of main inorganic and organic pollutants in terrestrial ecosystems, and to present knowledge on the relationships between land use, soil and water quality
- Describe how microbes interact with soils and how this affect pollutant degradation
- Describe key properties and processes of pollutants critical for sorption, abiotic and microbial degradation, bioavailability and biomagnification in terrestrial systems
- Classify and summarize the molecular mechanisms controlling pollutant degradation, transformation and bonding in soils and water
- Acquire knowledge on the methods available for predicting the fate of chemical substances in soil and aquatic environments
- Describe analytical procedures and monitoring strategies for pollutants in terrestrial systems
- Retrieve and critical examine environmental chemical data
- Apply and demonstrate the use of general principles from chemistry and microbiology for quantification and evaluation of pollutant fate and balances
- Estimate chemical and physical properties of pollutants and pollutant fate in terrestrial ecosystems
- Suggest methods and approaches used for assessing microbe-pollutant interactions
- Critically report on pollutant fate and remediation in terrestrial and aquatic environments
- Combine data and information from different sources in calculus, prediction and evaluation of pollutant mass balances, fate and effects in soils and aquatic systems
- Judge the relative importance of various sorption and transformation processes on the overall distribution and fate of chemical substances in soil and aquatic environments
- Diagnose the processes critical for the fate of any pollutant, and critical select tools for analysis and evaluation
- Discuss and assess the complexity of how land use affect soil and water quality
- Collaborate with fellow students on problem solving and reporting critical pollutant assessments
- Point to new directions and aspects of emerging pollutants
