Overview
This study measured Cu, Ni, Zn, Cr, and Pb in vegetables grown around Loumbila Dam in Burkina Faso. It is routeable as site-specific vegetable occurrence evidence with dry-weight concentrations.
Key numbers
- Table 3 reports values in mg/kg dry weight.
- Carrot values were Cu 17.6, Ni 11, Zn 42.95, Cr 1.3, and Pb 27.02 mg/kg dry weight.
- Onion-leaf values were Cu 16.4, Ni 11.16, Zn 57.72, Cr 3.72, and Pb 10.48 mg/kg dry weight.
- Onion values were Cu 19.81, Ni 10.05, Zn 73.37, Cr 4.65, and Pb 11.52 mg/kg dry weight.
- Lettuce values were Cu 16.9, Ni 5.09, Zn 70.1, Cr 4.89, and Pb 15.44 mg/kg dry weight.
- Green bean values were Cu 16.06, Ni 8.58, Zn 78, Cr 5.89, and Pb 4.09 mg/kg dry weight.
- Bell pepper values were Cu 19.65, Ni 7.01, Zn 70.39, Cr 3.56, and Pb 1.73 mg/kg dry weight.
- Across matrices, reported averages were Cu 17.74, Ni 8.82, Zn 65.42, Cr 4.00, and Pb 11.71 mg/kg dry weight.
Methods
The paper analyzes vegetable samples from an agricultural area influenced by Loumbila Dam conditions. Values are reported on a dry-weight basis.
Implications
The source fills vegetable occurrence context for Burkina Faso, especially for carrot, onion, lettuce, green bean, and bell pepper. The site-specific dry-weight basis should be retained during routing.
