- 5. The five spheres of the Earth System
- 6. Application areas of environmental analysis and monitoring.
- 8. Scales of space.
- 9. Scales of time.
- 10. Monitoring Methodical requirements: high sensitivity of measurements, producing analytical information continuously in real time or with
- 11. Monitoring 2. Technical requirements: automatic zeroing and instrument calibration, protection against abrupt power failure, equipping instruments
- 12. Classification of Trends in Monitoring Environmental Analytics methodological trends in environmental analytics and monitoring: dissemination of
- 13. Classification of Trends in Monitoring Environmental Analytics 2. trends in the area of instrumentation: new designs
- 14. Present methods and techniques of determination of total parameters can be classified: 1. Area of practical
- 15. EQS Environmental quality standards (EQS) mandate the level of permissible pollution in order to protect human
- 16. Regulating quality of the environment Environmental regulation implies measurement of a permissible environmental load. A load
- 17. Regulating quality of the environment Establishment of environment quality and quality of food is based on
- 18. Regulating quality of the environment Sanitary and hygiene regulation is based on the notion of maximum
- 19. Regulating quality of the environment Therefore sanitary and hygiene regulation covers all environments, various processes, which
- 20. Regulating quality of the environment For substances, on which we have not obtained sufficient information, temporary
- 21. Regulating quality of the environment Development of sanitary and hygiene standards is within the competence of
- 22. Toxic dose It should be noted, that some authors introduce other characteristics, interpreting toxicity as the
- 23. Toxic dose There are median lethal doses (LD 50), absolutely lethal doses (LD 100), minimal lethal
- 24. Comparing the toxicity of chemicals
- 25. Definitions
- 26. Increasing adverse effect with increasing dose
- 27. Acute and chronic toxicity Acute toxicity is an adverse effect seen soon after a one-time exposure
- 28. The MPC (МАС) concept Therefore, the volume of a toxic dose is not applicable within regulation.
- 29. The MPC concept Certain environments, being in close to natural (background) condition, contain a number of
