Abstract

The present study employed six paint furniture workshops; A, B, C, D, E and F, which have small and different size and types of painting, in close to carpenter workshops at El-Shoaraa in Damietta city. The particulate matter of PM10 and PM2.5 were measured, using Casella device for dust detective (Casella Cel-712 Microdust Pro Real-Time Dust Monitor). On the other hand, total suspended particulate (TSP) samples were collected using sampling air pump connected an open face holder on Whatman glass fiber filter. Metallic constituents of TSP were determined, using Atomic Absorption Spectrophotometer (A.A.S). The study results indicated that the mean concentrations of PM10 ranged from 26.85 to 44.41 µg/m3, whereas, the mean concentrations of PM2.5 ranged from 39.5 to 125 µg/m3. The TSP concentrations ranged from 359 to 410 µg/m3. The most paint particulate matters (PM) detected have unacceptable concentrations.

The mean heavy metals concentration of Pb, Cd and Zn in paint furniture workshops was (14.59, 7.59, 10.82) µg/m3, respectively. Thus, the present study evaluated concentrations of dust that might generate in the indoor air of workshops involving spray painting and varnishing. Therefore, to protect air quality and painter’s safety, and health concerns, occupational health and safety regulations, its implementation and enforcement within spray-painting furniture workshops must be improved and to ensure greater attention mitigations and management is given.
