Subject aims expressed by acquired skills and competences
Knowledge rendered upon completion of the course: Obtaining increased knowledge and understanding of the reactivity of organic and inorganic compounds. Depending on the previous study it is to gain knowledge on sampling from different environments (eg.: surface water, soil, waste), and their further processing lab, including presentation and evaluation of the results.
Skills rendered upon completion of the course: After successfully completing the course will graduate a comprehensive overview and understanding of the theoretical and practical aspects in environmental fields.

Summary
The aim of the course is to broaden and deepen the knowledge of chemical laboratory techniques, including the acquisition of practical skills focused on the analysis of both waste, raw materials and other types of environmental samples (air, water, PM, green matter, etc.). The aim of the course is to deepen students' readiness to solve analytic problems by selected instrumental methods not only in the laboratory but also in the field. Provide an overview of selected analytical methods and procedures used to analyze real environmental samples and chemometric evaluation of analytical results.

Additional study materials
Way of continuous check of knowledge in the course of semester
Successful processing of part-time assignments in the semester related to laboratory practice; computational and theoretical control tests. Laboratory tasks are chosen to always include individual types of laboratory techniques (sampling and sample preparation, spectrophotometry, volumetry, potentiometry, electrochemical separation methods, etc., including presentation and evaluation of obtained results). Each student works individually on the solved task and draws up a laboratory protocol, which he submits for inspection. The level and accuracy of the laboratory protocol is evaluated by a point assessment. Verification of the acquired knowledge is done by means of control tests (computational and theoretical) and the final credit test.
E-learning
Other requirements
Active participation in practice and submission of all protocols from laboratory tasks. Successful processing of partial tasks related to laboratory practice, which are given in the semester (sampling, sample preparation, etc.). Successful completion of written tests (computational and theoretical) prior to commencing a practical task when the student proves that he / she is sufficiently prepared to solve the given practical task. The requirement is also to successfully pass the final credit test.
