Module Description: Following this course, students will be able to critically assess and analyse the chemical processes that occur in the environment, with reference to the impacts of various natural and human inferences on associated biogeochemical cycles.
 
Module Learning Outcome
On successful completion of this module the learner will be able to:
# Module Learning Outcome Description
MLO1 Appraise the role of environmental chemistry and biochemistry in the geosphere.
MLO2 Evaluate the fundamental processes that drive biogeochemical cycles at a local scale.
MLO3 Evaluate the effects of human-related pressures on biogeochemical cycles at a global scale, including global climate change.
MLO4 Describe and relate aspects of environmental chemistry and biochemistry to the physical environment.
MLO5 Quantify and assess changes in key chemical cycles in the environment.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named DkIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Module Indicative Content
Environment and its chemistry
Structure and composition of main spheres in the environment; inter-relation of different spheres.
Atmospheric chemistry
Composition of the atmosphere, chemical processes, solubility of atmospheric pollutants in water; large-scale climate effects, including human related climate change, chemistry of acid deposition. Air quality standards. Gas sampling and analytical techniques.
The lithosphere
Composition and structure; weathering; leaching; soil chemistry; mineral resources and pollution; geochemical solubility.
The hydrosphere
Chemical composition and physical properties; water cycle; equilibria in aqueous systems; water pollution; large-scale human-related effects e.g. ocean acidification.
The biosphere
Composition, major and minor elements; toxicology of heavy metals and organic pollutants, bioaccumulation.
Biogeochemical cycles for various elements.
Biogeochemical cycling of for C, N, P, and S, and effects of human-related pressures.
Site Visits
Site Visits will be conducted to nearby industry to gain insight into the systems in place which aim to mitigate against environmental pollution. Example industry includes Tara Mines in Navan, Indaver Incinerator in Co. Meath and the Xerox plant in Dundalk.
Practicals
A range of practicals which addressing issues relating to soil-water chemical interactions and air pollution will be conducted. An empahsis will be placed on the appropriate use of instrumentation for the analyses, identification and quantification of enivornmental consitutents and pollutatants e.g.: Use of AAS to determine the effect of bioremediation on arsenic polluted water; Comparison of CE and HPLC techniques for the determination of a range of antibiotics in waste water.

Workload Type Contact Type Workload Description Frequency Average Weekly Learner Workload Hours
Practical Contact A range of skills will be implemented in the practicals. For example, students will will collect and analyse water and soil samples on the AAS and Lachat for heavy metals and nutrients. Students will design experiments to assess the impact of heavy metals on Gammarus. There will be site visits and fieldtrips to related facilities. Every Week 3.00 3
