The Jeonnam Health and Environment Research Institute announced that both its main and eastern branches received a 'satisfactory' rating in all categories during the National Institute of Environmental Research's regular proficiency test for indoor air quality and odors.
The institute confirmed the accuracy and quality control of its testing and analysis in the fields of indoor air quality and odors on September 9.
Proficiency tests are a quality control system designed to objectively evaluate the testing and analysis capabilities of environmental testing and inspection agencies. Each agency analyzes standard samples and compares the results to reference values to assess accuracy and reliability.
The evaluation for indoor air quality included seven items: benzene, toluene, ethylbenzene, xylene, styrene, total volatile organic compounds (TVOCs), and formaldehyde.
In the odor category, the analysis capabilities for complex odors, four types of aldehydes, and three types of volatile organic compounds were assessed.
Both the main and eastern branches of the Jeonnam Health and Environment Research Institute received satisfactory ratings in all evaluated categories.
Accurate measurement and analysis of pollutants are essential for indoor air quality, especially in public facilities where citizens spend extended periods. Similarly, odor measurement is crucial for addressing community complaints and managing business operations, making the objectivity and accuracy of test results vital.
Lee Jeong-il, head of the Environmental Investigation Division at the Jeonnam Health and Environment Research Institute, stated, "The satisfactory ratings across all categories confirm our analytical capabilities and the reliability of our test results. We will continue to provide accurate environmental measurement services through ongoing quality control and enhancement of our analytical capabilities."
Meanwhile, proficiency tests are a system for continuously managing the accuracy of analytical results produced by testing and inspection agencies, evaluating measurement capabilities by comparing results from similar samples against reference values. The Jeonnam Health and Environment Research Institute plans to maintain quality control in environmental testing for indoor air quality and odors based on the results of this evaluation.
