Risk Analysis of Total Suspended Particulates at Building Construction Area on Workers’ Health
Background: TSP (Total Suspended Particulates) are one of the air pollutants produced by building construction activities, where TSP can result in adverse effects to human health. Continuous exposure of TSP can cause respiratory problems. Therefore, a study of risk by TSP at building construction sites towards the workers’ health is highly necessary. This research examined the exposure of TSP at a building construction project which consists of three stages of works, namely concrete mixing activity, lean concrete activity, and transportation of materials. The main objective of this research is to analyze the amount of TSP exposed to the workers and to analyze the health risk of the TSP. Method: At each type of work, two sampling points are chosen. The risk analysis consists of four stages, namely hazard identification, exposure assessment, dose-response assessment, and risk characterization. TSP were measured using Dust Sampler DS 600-MVS. This equipment measured all of the dust particles ranged 0.01 to 100 μm. Results: The highest concentration of TSP measured was 795.691 μg/Nm3 found at materials transportation activities sampling point 1 and the lowest concentration measured was 186.811 μg/Nm3 found at lean concrete activity sampling point 1. The highest level of individual carcinogenic risk was in the amount of 0.0514 or 5.14% which was found in a worker working at the material transportation activities sampling point 1 and the lowest was in the amount of 0.0077 or 0.77% which was found in a worker working at the lean concrete activity sampling point 1. Conclusion: TSP risk values for all respondents resulting from the calculation were more than 1 × 10−4 or already above the acceptable safe level. It showed non-acceptable value and therefore it can potentially cause cancer.
