In the Slovak Republic (SR) there has not been a complete and coordinated monitoring system for environment until now. The object of environmental monitoring in the SR has been to evaluate certain areas, e.g. components of the environment and the influences affecting it: atmosphere, water, soil, biota (fauna and flora), geological factors, physical fields, forest, wastes, settlement, landuse, contaminants of the food chain and human stress caused by environmental factors. Individual monitoring systems are being built on the basis of these projects.The Monitoring System for the Environment in the SR has been formed by linkage to the Information System on the Environment in the SR which is a basic source of the data on the state of the environment in the SR and the factors affecting it.The guarantor of both these systems is the Ministry of the Environment of the Slovak Republic.
