Abstract

Objectives: This study aims to assess the current status of work environment measurement (WEM) for carcinogenic, mutagenic, reproductive toxic substances and to identify their high-risk industries for hazard surveillance and risk assessment. Methods: WEM Data from 37 specially managed CMR substances (2018-2022), the high-risk industries were identified by using estimated 95th percentile levels (X0.95) of measurements compared with the occupational exposure limit (OEL). Results: The substances most frequently measured were nickel (insoluble), followed by sulfuric acid, lead, chromium (VI), formaldehyde, phenol, dimethylformamide and benzene. The industries with highest number of measurement samples for special management substances were plating of metals, followed by hospitals, general repair services of motor vehicles, building of ships, manufacture of synthetic resin and other plastic materials, manufacture of finished medicaments. Out of the 37 special management substances studied, 22 had a non-detection rate of over 90%. The rate of samples exceeding the OEL was less than 1% for all substances. The substance with the highest number of samples exceeding the OEL was trichloroethylene, which also had the highest average concentration compared to exposure limit. The substances with the highest percentage of industries which (X0.95) exceeding OEL was formaldehyde followed by sulfuric acid, trichloroethylene, lead, I-bromopropane etc. Conclusions: This study identified high-risk industries of CMR sunstances, highlighting the need for prioritizing these industries in hazards surveillance and risk assessment.
