This is an irrigation field trial, not a market survey. Sprouts (the edible part) were analyzed separately from leaves. The table header is mg/g. The discussion calls the sprout lead figure mg/g dry matter. Control and treated municipal wastewater (TMWW) are kept separate. No quality-assurance recovery is printed for cadmium, nickel, or lead. Six replications are described.
Key numbers
Table 3 sprout columns, mg/g.
| Metal | Control | TMWW |
|---|---|---|
| Cadmium | 0.80 | 1.17 |
| Nickel | 5.70 | 6.17 |
| Lead | 6.08 | 0.77 |
The discussion sentence that the average lead was 0.77 mg/g dry matter is the TMWW cell, not the control. Fresh-matter restatements are not used. Leaf columns are not sprouts.
Methods (brief)
Plant matter was dried, ground, and dry-ashed. The design compares control irrigation with treated municipal wastewater.
Evidence fitness
The sprout columns support a field-trial note. They do not support a market-basket concentration.
Limitations
Not market samples. Unit is mg/g as printed. No recovery for these metals.
