Metal pollution and consumer risk in two governorates
3. Study design and population
- Study design
- Measurement / residue study – Metals in water, sediment and fish from polyculture ponds with health risk
- Population
Tilapia (bolti) and mullet (topara)
- Country
Egypt (El-Sharkia, Kafr El-Sheikh)

5. Actual results
- Results
El-Sharkia ponds more contaminated; THQ/HI for muscle indicate safe non-carcinogenic risk; cadmium poses a cancer risk to children consuming bolti from El-Sharkia ponds.
