Laboratory studies of the sanitary protection zone (SZZ) of enterprises is an important stage of monitoring compliance with established hygienic standards and assessing the impact of production factors on the environment and public health.

The purpose of laboratory research:

• Evaluation of the effectiveness of SZZ: confirmation of the compliance of the dimensions of the PPE with the requirements of the law and established standards;
• Control of pollution levels: measurement of concentrations of harmful substances (chemical, physical, biological) on the border of the SZZ and beyond;
• Environmental monitoring: observation of changes in atmospheric air quality, soil, water in the zone of influence of the enterprise;
• Identification of pollution sources: identification of specific production processes, which is the reason for exceeding the standards;
• Development of mitigation measures: justifying the necessity and choosing effective methods of reducing the negative impact of the enterprise on the environment.

Object of research:

• Atmospheric air: measurement of pollutant concentrations (dust, step on, money), noise, vibration;

Periodicity and volume of research:

The periodicity and volume of laboratory tests are determined by the control program, developed for a specific enterprise taking into account its features, hazard class and legal requirements. Research is usually conducted regularly, with a set frequency (monthly, every quarter, annually).

Research methods:

Various methods are used for laboratory research, in particular:

• Chemical analysis: gas chromatography, liquid chromatography, spectrophotometry, atomic emission spectrometry, etc;
• Physical methods: noise measurement, vibrometry, thermometry;

Processing of results:

The results of laboratory studies are drawn up in the form of reports, protocols. The documents state:

• date and place of sampling;
• research methods;
• obtained results;
• comparison with normative values;
• conclusions regarding the state of the environment and the effectiveness of the SZP.

Legislative regulation:

Laboratory studies of the sanitary protection zone (SZZ) are carried out in accordance with the requirements of current legislation in the field of environmental protection and sanitary-epidemiological well-being of the population.

The importance of laboratory research:

Laboratory studies of SZZ are a necessary tool for ensuring environmental safety and public health protection, which lives near industrial enterprises. Research results are the basis for decision-making regarding the regulation of enterprise activities, development of measures to reduce negative impact and ensure sustainable development of industry.
