Overview
This study measured lead and cadmium in watermelon and carrot and compared values with permissible limits. It is directly routeable for carrot/root-vegetable and fresh-fruit occurrence context.
Key numbers
- Watermelon Pb averaged 18.68 +/- 16.1 ug/kg, with a range from not detected to 74.43 ug/kg; no samples exceeded the 100 ug/kg permissible limit used by the authors.
- Carrot Pb averaged 30.83 +/- 15.88 ug/kg, with a range from 0.81 to 76.88 ug/kg; no samples exceeded the 100 ug/kg permissible limit.
- Watermelon Cd averaged 2.40 +/- 2.72 ug/kg, with a range from not detected to 13.40 ug/kg; no samples exceeded the 50 ug/kg permissible limit.
- Carrot Cd averaged 5.25 +/- 3.47 ug/kg, with a range from 1.75 to 26.20 ug/kg; no samples exceeded the 50 ug/kg permissible limit.
Methods
The paper reports Table 1 summary statistics for Pb and Cd in each matrix. Nitrate values are also reported in the source but are outside the heavy-metal ingest scope.
Implications
The source supports Iranian carrot and watermelon occurrence context with low-to-moderate Pb and Cd values relative to the comparison limits used in the paper. The values are suitable for routing as matrix-specific summary statistics, preserving the ug/kg basis.

Verification notes
The page excludes nitrate from the routed metal scope. Units are preserved as ug/kg from the source table.
