Packing of raw materials in work environments is a known source of potential health
impacts (respiratory, cardiovascular) due to exposure to airborne particles. This activity
was selected to test different exposure and risk assessment tools, aiming to
understand the effectiveness of source enclosure as a strategy to mitigate particle
release. Worker exposure to particle mass and number concentrations was monitored
during packing of 7 ceramic materials in 3 packing lines in different settings, with low
(L), medium (M) and high (H) degrees of source enclosure. Results showed that
packing lines L and M significantly increased exposure concentrations (119-609 μg m-3
respirable, 1150-4705 μg m-3 inhalable, 24755-51645 cm-3 particle number), while nonsignificant
increases were detected in line H. These results evidence the effectiveness
of source enclosure as a mitigation strategy, in the case of packing of ceramic
materials. Total deposited particle surface area during packing ranged between 5.4-11.8x105 μm2 min-1, with particles depositing mainly in the alveoli (51-64%) followed by
head airways (27-41%) and trachea bronchi (7-10%). The comparison between the
results from different risk assessment tools (Stoffenmanager, ART, NanoSafer) and the
actual measured exposure concentrations evidenced that all of the tools overestimated
exposure concentrations, by factors of 1.5-8. Further research is necessary to bridge
the current gap between measured and modelled health risk assessments. [-]
