Environmental Quality Monitoring & Analysis

Indian Institute of Technology Madras and NPTEL via Swayam


The course is directed at measuring, modeling and assessing the parameters of environmental quality for the purpose of environmental risk assessment. The course introduces readers to the concept of environmental fate and transport and the methods to apply them in environmental risk assessment. The course also discusses the monitoring methods in the context of environmental fate and transport.INTENDED AUDIENCE : Interested LearnersPREREQUISITES : Basic Mathematics; Physics; Chemistry; Environmental Engineering; Chemical Engineering.INDUSTRY SUPPORT : Environmental Consulting


Week 1: Introduction; Definition of Environment; Link between source/environment/receptor; Exposure; Health effects; Toxicology; Defining the need for fate and transport.
Week 2: Chemicals of concern; relevant properties for environmental fate and transport; Definition of Equilibrium – partition constants, solubility, vapor pressure, henry’s constant, Koc, Kow etc. Equilibrium partitioning of chemicals between different phases of the environment.
Week 3: Parameters for environmental water/ air / soil / sediment – screening parameters, priority air pollutants – definitions of PM
Week 4: Monitoring of environmental parameters – screening parameters – BOD, COD, TOC, TDS; Environmental sampling – definition and synthesis of a monitoring/sampling/analysis method. Quality Assurance and quality control (QA/QC).
