Abstract. This paper investigates the practical approach of reducing air pollution caused by particulate matter (PM10 and PM2.5) in Andijan City through the method of street watering. To assess the effectiveness of this method, air quality was monitored using AQI indicators, emphasizing metrological accuracy, proper calibration of instruments, and compliance with international standards. The study highlights the role of metrology and standardization in environmental monitoring, evaluates the reliability of measurement methods, and analyzes the benefits of standard-based management in street watering systems. Results show that regular watering can reduce AQI values by up to 30% under dry climatic conditions. Recommendations for technical regulation, system optimization, and public health awareness are provided.
