Vegetables are essential for human nutrition due to their low fat content and high levels of vitamins, minerals, and dietary fiber. However, studies have shown that vegetables are vulnerable to PTE contamination as a result of anthropogenic activities. This study determined the concentrations and health impacts associated with potentially toxic elements (PTEs) in specific vegetables (green beans, spinach, green pepper, carrots, and onions). A total of 90 vegetable samples were randomly selected and purchased from local markets and analyzed for potentially toxic elements (PTEs) (Cd, Fe, Cr, Pb, Cu, Zn, Co, and Ni) using an atomic absorption spectrophotometer (AAS). The mean concentrations (mg·kg-1) of PTEs ranged from 0.006 - 0.021 for Cd, 2.27 - 12.32 for Fe, 0.05 - 0.150 for Cr, 0.087 - 0.254 for Pb, 0.035 - 0.062 for Cu, 2.65 - 15.61 for Zn, 0.010 - 0.050 for Co, and 0.012 - 0.058 for Ni. The abundance of PTEs was found to be in the following declining order: Zn >Fe >Cu >Cr >Ni >Co >Pb >Cd. The hazard index (HI) for both children and adults was <1, suggesting that there is no likely non-carcinogenic effect from consuming these vegetables. Similarly, the carcinogenic risk was below the acceptable value range of 1.0 × 10-6 - 1.0 × 10-4. Based on the results of this study, it is unlikely that the vegetables analyzed pose a health risk to consumers. However, monitoring and continuous stringent regulations of PTEs on foodstuff for public health protection.

BACKGROUND: Pregnancy-related low back pain is a common complaint with numerous adverse consequences. Unfortunately, the effect of healthrelated quality of life and physical activity status on pregnancy-related low back pain remains understudied. OBJECTIVES: This study aimed to examine the influence of physical activity and health-related quality of life on pregnancy-related low back pain among pregnant women. METHODS: A survey of 398 pregnant women was conducted using the Modified Pregnancy Low Back Pain, Medical Outcome Survey Short Form (MOS-SF), and Pregnancy Physical Activity Questionnaire (PPAQ) to assess pregnancy-related low back pain, quality of life, and physical activity status among the participants. RESULTS: About fifty-four percent (54%) of the pregnant women reported experiencing low back pain during pregnancy. There were no significant differences between most physical activity intensities and domains for pregnant women with and without pregnancy-related low back pain, with the exception of women identified as sedentary (12.9±14.8 versus 17.4±16.2) or inactive (18.7±20.0 versus 23.6±19.8). Furthermore, waist circumference (OR: 0.97; 95% CI: 0.96 to 0.99) and Physical component scores (PCS) (OR: 0.96; 95% CI: 0.93 to 0.98) were associated with pregnancy-related low back pain. An interaction of height and occupation also showed an association with pregnancy related low back pain (OR: 1.04; 95% CI: 1.01 to 1.08). CONCLUSION Sedentary and inactivity are the only physical activity intensity and domain associated with pregnancy-related low back pain, which affect the physical well-being of the expecting mothers.
