Introduction. After the Iraq war, the dust phenomenon has increased in western Iran. Our study aimed to evaluate the effect of the dust
phenomenon on the content of heavy metals in raw milk in Ilam province.
Study objects and methods. The dust samples were collected during one year. The concentrations of dust particles were determined
with the Enviro Check Laser System, using the Dust Monitor Check. The concentration of heavy metals in dust was determined by
using the high volume air samplers and glass fiber filters.
Results and discussion. Heavy metals (lead, arsenic, zinc, copper, and iron) were measured at four sampling sites in raw milk by
the atomic absorption method. The mean and standard deviations of dust particulate matter (PM10 and PM2.5) were 105.6 ± 90.5 and
25.9 ± 15.4 μg/m3, respectively. The amounts of arsenic, zinc, lead, and copper were higher in the spring and summer. Lead levels in
western and southern regions were higher than those in the east, center, and north.
Conclusion. We found similar trends for arsenic, zinc, copper, and iron in raw milk. Our results showed the potential effect of the dust
phenomenon on the presence of heavy metals in raw milk.
