1. Assessment of the environmental degradation; - Understanding the basic concepts of interdependence between the pollution factors and their direct effects on the environment - Identifying interdependence between the pollution factors and their direct effects on the environment - Evaluation the environmental monitoring programs 2. Identification and compliance with professional ethics and deontology, taking responsibility for decisions and risks 3. Identify roles and responsibilities in a multidisciplinary team and application the techniques and effective work relationships within the team.
