Recently, scrutiny of health risks associated with air pollutant emissions resulting from shipyard operations have increased. Based on the preliminary assessments, it appears that welding and blasting operations are driving the public health risks in the shipbuilding sector due to anticipated metal emissions and their associated toxicity.
The main objective of this project was to generate additional data on PM10/TPM fraction and metal fractions of TPM for total chromium, manganese, nickel and lead. Particle size distribution data (PM10 fraction) and the metal fraction of airborne total PM (TMP) presented in the final report will be of great use in correctly determining the inhalation induced health risks or residual risks anticipated from dry abrasive blasting processes.
