Summary

Researchers measured the oxidative potential (OP) of street dust samples from Kerman, Iran using a dithiothreitol assay and found strong correlations between OP and arsenic and chromium concentrations, with higher oxidative activity concentrated in the city center and west — suggesting OP can serve as a practical metric linking heavy metal sources to potential human health effects from dust inhalation.

The current study aimed to consider oxidative potential (OP), its spatial distribution, and correlations with heavy metals (HMs) in street dust in Kerman city, Iran. The concentration of HMs in 35 street dust samples was detected by ICP-AES. The OP in samples was measured through dithiothreitol (DTT). The mean concentration of elements followed Zn > Cu > Pb > Cr > As > Cd. The OP value was found to be 7.17 ± 2.98 nmol/min. µg dust in the current study. A strong correlation was observed among the concentrations of As and Cr and OP values in dust samples. More values of OP were observed in the center and west of the Kerman city. According to results of the current study, it could be concluded that OP can be applied as metrics of pollution originated from different sources and human health effects. The amount of OP in the street dust in the Kerman city can be reduced through the use of clean fuels.
