GREEN SENTINEL
One of the 50 measures set out in Debrecen's environmental programme, the Green Code, is the establishment of an Environmental Audit Scheme. This Green Sentinel is the only automated information and data collection, analysis and monitoring instrumentation system in the country, designed by professionals, operated and monitored 24 hours a day, monitoring the state of our environment through continuous sampling and analysis.

CONSTRUCTION IN PROGRESS
The construction of the metering stations is progressing well.On 11 November 2024, the Board of Directors was informed about the progress of the works in the immediate vicinity of the Southern Economic Belt. The construction of the metering stations has reached the finishing line and the infrastructures are ready to receive the equipment. The progress of the works was checked by visiting a complex metering station and a surface water metering station.

BASELINE MONITORING
Baseline monitoring is a prerequisite for monitoring and controlling changes in the environment, i.e. the precise assessment and recording of the baseline condition. Any changes that may occur in the environment can be compared to this. The baseline monitoring involves the assessment of surface water, groundwater, ambient air quality and soil conditions, and the associated baseline environmental assessments using accredited measurements.

EQUIPMENT OF MONITORING STATIONS
How do we test the state of our environment? Complex and automatic samplers, quality control stations, probes and many other instruments support the work. Instruments and sensors provide continuous online data. Some instruments also take samples of our environment (air, aerobic and water samples), which form the basis for laboratory tests. This will be complemented by physical sampling (soil, surface water, groundwater, biodiversity) and laboratory testing by experts in the field. You can find out more on our website.

MONITORING STATIONS
The Environmental Monitoring System consists of 16 complex monitoring stations and 2 surface water monitoring stations, forming a coherent system covering the whole city. The locations of the monitoring stations have been selected to be representative of larger similar areas. The stations with the highest representativeness are those in residential areas, garden and residential inner city areas and economic zones.

SCIENTIFIC PROGRAMME
The scientific programme contains details of the assessment of the following environmental elements: air quality, surface water, groundwater, soil and biodiversity. To this end, working groups have been set up to prepare the technical implementation for each environmental element. The work of the scientific working groups is supported by horizontal working groups. The IT working group is responsible for the recording and organisation of the measurement data and the development of the software environment (database, communication interfaces, data description structures, query systems, secure channels, etc.). The Legal-Economic Working Group will support the work of the specialised working groups by synthesising the sectoral proposals for legal regulation coming from the working groups, translating the needs expressed in a scientific manner into legal standardisation and managing the legislative process.

GLOSSARY
ENVIRONMENTAL ELEMENT
Land, air, water, wildlife and the man-made (built) environment and their components.
HEALTH LIMIT VALUE
The maximum permissible concentration of a substance (e.g. pollutant, chemical, noise) in the environment or a given medium (e.g. air, water, food, workplace environment) that does not cause long-term health effects to humans. Hungarian legislation sets both short-term (hourly or daily) and long-term (annual) air pollution levels. Long-term levels are more stringent than short-term levels because long-term exposure to pollutants can cause serious health effects.
INFORMATION THRESHOLD
The concentration of pollutants above which the local authority is obliged to inform the public of the current air quality status. This value is lower than the alert threshold and does not necessarily justify more stringent action, but it does provide a warning that air quality is no longer ideal. The information and alert thresholds for nitrogen dioxide, particulate matter, sulphur dioxide, carbon monoxide and ozone, which form the basis for the different stages and measures of the smog alert, are set out in Annex 3 to VM Decree No 4/2011 (I. 14.) on air pollution level limits and emission limit values for stationary sources of air pollution (hereinafter: VM Decree). The Mayor is authorised to order and lift the stages of the smog alert on the basis of the Smog Alert Plan. The requirements for the preparation of the smog alert plan are set out in Government Decree 306/2010 (XII. 23.) on air protection. The National Air Pollution Monitoring Network is responsible for monitoring air pollution levels and compliance with air pollution limit values in Hungary in order to assess national air pollution.

My Green Sentinel
SCIENCE IS AT YOUR SERVICE!
Scientists and professors from the University of Debrecen and the City of Debrecen have jointly created the Green Sentinel, which monitors the environmental condition of your living environment.

The Green Sentinel, or Environmental Control System, consists of 16 complex monitoring stations and 2 surface water monitoring points, selected by experts to cover the whole city, including residential areas, forested areas and industrial sites.

Select the closest monitoring point to you on the map to find out about the status and trends in air, water, soil, noise and biodiversity!

Green Sentinel is a complex monitoring system that provides you with data 24 hours a day, 7 days a week. Designed by experts, it is a continuous information and data collection, analysis and monitoring system based on objective measurements, using instrumental observation and continuous sampling to monitor changes and conditions in air, surface and groundwater, soil and wildlife.

The development, safety and well-being of Debrecen is our common cause, so we want you to be part of the Green Sentinel! Join our Citizen Science programmes to learn more about how the system works, how our scientists research, measure results and what and how it affects your environment.

Join us, let's do something together for Debrecen!
