Application of Multiple Occupational Health Risk Assessment Models for Crystalline Silica Dust among Stone Carvers.
Rahimimoghadam et al., Asian Pac J Cancer Prev 2023
DOI: 10.31557/APJCP.2023.24.11.3999
Study Highlights:
- Objective: To measure the occupational exposure of stone carvers to crystalline silica and evaluate associated health risks.
- Methods: Air sampling for 79 stone carvers, using NIOSH7500 method and XRD for silica measurement. Risk assessments were conducted using Singapore Department and US EPA methods, with mortality estimates from Manettej and Rice models, analyzed via SPSS23.
- Findings: Mean exposure to inhalable dust and crystalline silica was 1.44 mg/m³ and 0.5 mg/m³ respectively, exceeding occupational standards. High risk of silica exposure with carcinogenicity risk at 7.40 × 10-6 and 3.12 × 10-7. Non-carcinogenic risk was deemed unacceptable. Estimated mortality rates for silicosis and lung cancer were 3-12 per thousand and 150.24 per thousand respectively.
- Significance: The study underscores the need for stringent control measures to mitigate the high health risks stone carvers face from silica exposure.
