This subject covers the main sources and types of environmental contaminants in the biosphere (water, soil and air) with a focus on water contaminants and their effect on water quality. The most frequently used analytical techniques in environmental and industrial monitoring and analysis will be outlined in the context of achieving desirable environmental outcomes. These techniques include volumetric analysis, gravimetric analysis, optical techniques such as inductively coupled plasma optical emission spectrometry, and electroanalytical techniques such as potentiometry (ion-selective electrodes, potentiometric stripping analysis) and voltammetry (polarography, anodic stripping voltammetry). Upon completion of the subject, students will have acquired an in-depth understanding of the origin, distribution and role of environmental contaminants, and be able to select suitable methods for monitoring them. Students will also learn to apply analytical and problem-solving skills to the consideration of treatment options for industrial effluents. From the practical component, students will acquire enhanced laboratory skills and competence in using modern laboratory techniques.

Ongoing assessment of practical work in the form of short laboratory reports due during the semester (50%); a 45-minute written test held mid-semester (10%); a 2-hour written examination in the examination period (40%). Satisfactory completion of both theory and practical work is necessary to pass the subject.
