This study aimed to evaluate arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) levels in dried chili peppers from nine districts in Guizhou Province. These heavy metals, widely dispersed and capable of transferring to crops, pose potential health risks to humans. The assessment included modeling daily intake (EDI), target hazard quotient (THQ), total target hazard index (TTHQ), and target carcinogenic risk (TCR) to assess health risks across different population groups. Results showed chromium (0.9540 ± 0.301 mg/kg) and lead (0.8949 ± 0.266 mg/kg) had the highest concentrations, followed by arsenic (0.3287 ± 0.093 mg/kg) and cadmium (0.0627 ± 0.017 mg/kg). Children exhibited higher EDI values than adults, indicating greater health risks from dried chili pepper consumption at equivalent levels. THQ and TTHQ values were below 1 across all regions, indicating no significant health risks associated with dried chili pepper consumption. Similarly, TCR values were below 10-4 for all nine regions, indicating an acceptable level of carcinogenic risk. Overall, consuming dried chili peppers in Guizhou Province poses an acceptable health risk, but caution is advised, especially for children, to limit heavy metal exposure.
本研究旨在评估贵州省九个地区干辣椒中的砷（As）、镉（Cd）、铬（Cr）和铅（Pb）含量。这些重金属广泛分布且能够转移到农作物中，对人类健康构成潜在风险。评估包括建模每日摄入量（EDI）、目标危害系数（THQ）、总目标危害指数（TTHQ）和目标致癌风险（TCR），以评估不同人群群体的健康风险。结果表明，铬（0.9540 ± 0.301 mg/kg）和铅（0.8949 ± 0.266 mg/kg）含量最高，其次是砷（0.3287 ± 0.093 mg/kg）和镉（0.0627 ± 0.017 mg/kg）。儿童的 EDI 值高于成人，表明在同等食用水平下，干辣椒对儿童健康的风险更大。THQ 和 TTHQ 值在所有地区均低于 1，表明食用干辣椒不会带来显著的健康风险。同样，九个地区的 TCR 值均低于 10-4，表明致癌风险处于可接受水平。总的来说，贵州省食用干辣椒带来的健康风险可以接受，但仍需谨慎，特别是对于儿童，要限制重金属的摄入。
