Environmental monitoring

Environmental monitoring: goals and objectives

 

A fundamental tool for a deep understanding of the state of ecological systems and their dynamics is environmental monitoring. It covers a comprehensive study of various components, from the quality of air, water and soil to the state of biodiversity, including plants and animals. The key task is not only to collect data on the current state of these elements, but also to analyze trends and changes over time to identify possible environmental threats and assess the sustainability of ecosystems.

 

Main directions of observation and control

 

The process of environmental monitoring and pollution involves developing methodologies for effective data collection and analysis, which requires the use of both classic and advanced observation technologies. This covers a wide range of activities, from ground-based surveys and laboratory studies to the use of satellites and drones for remote sensing. In addition to traditional methods, the use of digital technologies and big data for processing and analyzing environmental information is of great importance, which allows for improving the accuracy of forecasts and the effectiveness of environmental protection measures.

Special attention within the framework of environmental monitoring is paid to the identification of anthropogenic impacts, such as industrial emissions, agricultural activities and urbanization, which can lead to degradation. In this context, an important role is played by the analysis of the impact of human activity on natural processes and the development of strategies to reduce the negative impact on ecosystems.

In addition, environmental monitoring and pollution aims to develop recommendations and strategies for the protection and restoration of natural resources. This includes the creation of reserves and protected areas, the restoration of damaged ecosystems and the development of sustainable methods for the use of natural resources. Information obtained through monitoring provides valuable data for the development of national and international environmental policies and programmes aimed at environmental protection and sustainable development.

 

Types of environmental monitoring

 

Each type of monitoring is aimed at studying specific aspects of the ecosystem, which provides a holistic understanding of its state and dynamics of change and, as a result, helps to identify potential threats.

Monitoring the state of atmospheric air

 

Monitoring of atmospheric air quality is carried out through a network of meteorological stations and specialized observation posts distributed across various geographical regions. The observation posts are equipped with modern sensors and analytical equipment that allow real-time monitoring of the concentration of key pollutants such as carbon dioxide (CO2), nitrogen oxides (NOx), sulfur dioxide (SO2) and various dust particles. The data obtained is subject to careful analysis in order to assess the current air quality and determine when pollutant levels exceed established standards.

Radiation monitoring

 

This type of monitoring focuses on tracking radiation levels in the environment, which is especially important in the context of both natural background radiation and potential anthropogenic impacts, such as those from nuclear power plants or accidents. Radiation monitoring involves collecting water, soil and air samples for analysis of radioactive isotopes. This allows for the timely detection of radiation contamination threats and the necessary measures to protect the population and ecosystem.

 

Condition of precipitation and snow cover

 

Analysis of precipitation and snow cover provides important information about the state of the ecosystem, including an assessment of their impact on the quality of surface water, soil, and a wide range of living organisms. Studying the chemical composition of rain and snow water allows us to identify the presence of acid rain and other forms of pollution that can negatively affect nature.

 

Background monitoring

 

This type of monitoring is carried out in specially protected or remote areas where anthropogenic influence is minimal, which makes it possible to assess the natural state of ecosystems. Background monitoring plays a critical role in identifying global environmental changes such as climate change, global air pollution and biodiversity loss.

Monitoring the condition of surface waters

 

Surface water monitoring involves the regular collection and analysis of water samples from rivers, lakes, reservoirs and other bodies of water. This process aims to assess the chemical composition of water, the level of its pollution with organic and inorganic substances, as well as the state of the microbiological community. The information obtained is of key importance for ensuring the quality of drinking water, protecting aquatic ecosystems and developing strategies to prevent water pollution.

Levels of environmental monitoring

 

Depending on the region of coverage, monitoring is divided into several levels:

• Global monitoring covers the observation of climate change, the ozone layer, global pollution and other international environmental issues. This area includes programs and initiatives such as the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP).
• Regional environmental monitoring - focuses on the ecosystems of specific geographic regions, such as river basins, mountainous areas or coastal zones. Regional programs are aimed at solving problems related to pollution, natural resource management and biodiversity conservation.
• National monitoring involves monitoring the state of the environment within a specific country. This includes monitoring air and water quality, radiation levels, soil conditions and other indicators within the state.
• Local monitoring is carried out at the level of individual cities, industrial facilities or nature conservation areas. It is aimed at solving specific environmental problems such as urban pollution, waste management and the protection of vulnerable ecosystems.

Regional environmental monitoring

A systematic process of observing, assessing and controlling the state of the environment in a certain region is regional environmental monitoring. This process allows for continuous tracking of changes in the state and quality of air, water and soil, which helps maintain the balance and health of ecosystems at the regional level.

Regional programs are aimed at solving problems related to pollution, natural resource management and biodiversity conservation.

The objects of regional environmental monitoring are natural resources and ecosystem components including air, surface and ground water, soil, flora and fauna. In addition, monitoring includes the analysis of anthropogenic impacts, such as industrial emissions, agricultural activities and urbanization, which can significantly change natural conditions and the quality of life of the population.

Regional monitoring in Kazakhstan is carried out by Kazhydromet bodies, which collect, process and analyze environmental information. These bodies play a key role in the national environmental monitoring system, providing data for decision-making at the state and local levels. Kazhydromet uses both ground stations and modern technologies, including remote sensing and GIS technologies, for regional monitoring and forecasting of the environmental situation.

The system for monitoring the state and pollution of the environment in the region is aimed at ensuring sustainable development of territories and protecting public health. The system includes a set of measures, from regular collection of samples and data to conducting a comprehensive analysis of the information received with subsequent informing the public and government agencies.

Current state of monitoring research

 

 

Today, significant progress is being made in monitoring the state of the environment and pollution thanks to the introduction of new technologies and methods. The integration of remote sensing allows us to obtain data on the state of natural resources and ecosystems with high accuracy and on a large scale, which was previously unachievable. The use of satellite images and drones helps to monitor landscape changes, deforestation and the effects of natural disasters.

The Internet of Things has revolutionized the collection and processing of environmental data, allowing sensors to be placed at the most critical points to continuously monitor ecosystem parameters. These sensors record a wide range of indicators, from air and water quality to radiation and noise pollution levels, transmitting data in real time for analysis and action.

Artificial intelligence and machine learning open new horizons in the interpretation of collected data, allowing not only to analyze the current state of ecological systems, but also to predict future changes with a high degree of probability. These technologies contribute to the development of effective strategies to prevent environmental crises and minimize anthropogenic impact on the environment.

Involving the public and various organizations in the monitoring process stimulates the formation of a responsible attitude towards the environment and the intensification of efforts to protect it.
