Abstract
This study evaluates chemical health risks in laboratories at a malaysian higher academic institution using a combination of qualitative and quantitative approaches. The general objective was to assess exposure risks by integrating chemical health risk assessment (chra) with indoor air quality (iaq) evaluation. Initially, 79 laboratories were screened using chra to determine action priority (ap) levels. 34 of the laboratories were selected for detailed iaq monitoring. Measured iaq parameters included air temperature, relative humidity, air movement, carbon monoxide (co), carbon dioxide (co₂), volatile organic compounds (vocs), and particulate matter (pm₁₀), compared against industry code of practice on indoor air quality (icop iaq) 2010 limits. Statistical analysis used included descriptive, cross-tabulation, one-way anova, spearman correlation, pearson chi-square and logistic regression. Descriptive analysis revealed frequent non-compliance in temperature, co₂ levels, and airflow. Inferential analysis using spearman’s correlation identified a significant inverse relationship between air movement and co₂ concentration (p < 0.05), indicating poor ventilation. The findings highlight the importance of integrating iaq assessment with chra to identify high-risk environments and enhance chemical safety practices in academic laboratories.
