Abstract
Cement dust can contaminate the environment and surrounding agricultural soil, exposing crops to heavy metals and other environmental stressors. However, the impact of these dust emission on plants grown in prone areas is under studied. This study assessed the effects of cement dust exposure on heavy metal accumulation and oxidative stress biomarkers in Ipomoea batatas (Lam.). Soil, dust, and sweet potato samples were collected from four exposed locations and a control site. The concentrations of selected heavy metals (As, Cd, Cr, Ni, Pb, and Zn) were determined. MDA, H₂O₂, GSH, CAT, SOD, proline, vitamin C, and vitamin E were assessed as indicators of oxidative stress and antioxidant responses. Variations in heavy metal concentrations were observed among the soil samples, with all the analysed metals showing higher concentrations in dust and soil samples from exposed sites than in the control. As was not detected in the leaves and roots of sweet potatoes. In the leaf samples, Cd was 0.001 mg/kg at the control site but ranged from 0.003 to 0.007 mg/kg at contaminated sites. Pb was not detected in control samples but ranged from 0.005 to 0.086 mg/kg in leaves from contaminated sites. In root samples, Cd did not show a significant difference between control and exposed sites. Pb was not detected in the root samples. Oxidative stress responses were evident in both leaves and roots, with increased MDA and H₂O₂ concentrations at exposed sites. These changes were accompanied by variations in GSH, CAT, SOD, proline, vitamin C, and vitamin E, indicating activation of antioxidant defence responses. These findings indicate that cement dust exposure is associated with heavy metal contamination and increased oxidative stress in sweet potatoes, accompanied by biochemical responses consistent with activation of antioxidant defence mechanisms.

Key words: Cement dust, Heavy metals, Ipomoea batatas, Oxidative stress, Antioxidant defence, Sweet potato.
