| Aim: To provide a general basic knowledge of environmental chemistry as a discipline in its own; as a fundamental basis for understanding chemical pollution problems; and as a tool for environmental management and risk assessment. The latter subjects are taught with a view also to introducing the students to policy and regulatory aspects of chemical pollution control. |
Contents: About half the course is basics on environmental chemical fate - degradation, transport, and intermedia transfer and partitioning of organic chemicals present in different environmental compartments - e.g., water, aquatic sediments, aquatic biota, soil and air. The following processes are covered: biodegradation, hydrolysis, photodegradation, sorption, volatilization and bioaccumulation. The processes are evaluated related to physical-chemical and chemical structural properties and to characteristics of the environmental compartments in question. The knowledge acquired on chemical fate is used for quantifying exposure in chemical risk assessments, which are introduced at the course in an EU legislative framework.
Remaining topics in the environmental chemistry course include introductions to water chemistry, atmospheric chemistry, and the chemistry of heavy metals. Also the chemical cycles of the important elements carbon, nitrogen, phosphorus and sulphur are covered. This basis combined with chemical fate evaluations is used for chemical pollution assessments which among others are exemplified through specific lectures on environmentally important groups of chemicals (surfactants, pesticides, chlorinated compounds, metals), polluted soil, and pollution from industry and agriculture. Regulations and policies for preventing and mitigating chemical pollution are presented where necessary and include the establishment of criteria values for chemicals and metals. |
