Di Bella et al. 2020 - Augusta Meat, Milk, and Seafood Metals
Di Bella et al. measured heavy metals and PAHs in seafood, meat, and milk from the Augusta area in Southern Italy. The paper is direct occurrence evidence for seafood, beef, pork, and raw milk in a polluted-area context. It is not infant-formula evidence; the wishlist hit came from infant-formula comparison terms in the paper rather than sampled formula products.
Key numbers
Table 5 reports concentrations in ug/g.
| Matrix | tAs mean +/- SD | Cd mean +/- SD | Cr mean +/- SD | tHg mean +/- SD | Ni mean +/- SD | Pb mean +/- SD | Zn mean +/- SD |
|---|---|---|---|---|---|---|---|
| Beef | 0.012 +/- 0.008 | <LOD | <LOD | <LOD | <LOD | 0.019 +/- 0.027 | 48.94 +/- 11.94 |
| Pork | 0.015 +/- 0.012 | <LOD | <LOD | <LOD | <LOD | 0.024 +/- 0.034 | 44.91 +/- 13.43 |
| Cow milk | <LOD | <LOD | <LOD | <LOD | <LOD | 0.002 +/- 0.001 | 2.92 +/- 0.96 |
| Sheep/goat milk | <LOD | <LOD | <LOD | <LOD | <LOD | 0.002 +/- 0.002 | 2.77 +/- 1.18 |
| Total seafood products | 7.06 +/- 6.17 | 0.002 +/- 0.002 | 0.019 +/- 0.011 | 0.99 +/- 1.02 | 0.010 +/- 0.014 | 0.09 +/- 0.18 | 6.36 +/- 5.27 |
The authors report that all heavy metals were detected in seafood products, while most were below LOD in beef, pork, and milk. Seafood had the highest total arsenic, mercury, and lead means. Mercury in seafood drove the main non-cancer risk signal, with seafood THQHg greater than 1 for babies, children, and teenagers under the study’s consumption assumptions.
Methods (brief)
Seafood edible tissues were digested and analyzed for As, Cd, Cr, Ni, Pb, and Zn by ICP-MS; mercury was measured by direct mercury analysis. Milk and meat heavy-metal methods were validated against matrix-specific criteria and certified reference materials. The authors converted some seafood concentrations to wet-weight basis for exposure assessment and used half-LOD substitution for values below detection.
Implications
This source contributes polluted-area occurrence evidence for seafood and terrestrial animal products. It should route to seafood, marine fish/shellfish, beef, pork, and milk/dairy contexts, with a clear jurisdiction and contamination-source caveat. It should not fill infant-formula rows, because no infant formula was sampled.

Verification notes
- Batch 2 auto-fetched ingest, 2026-05-25. The wishlist filename targeted cow-milk/infant-formula inorganic arsenic, but the actual paper reports meat, raw milk, and seafood occurrence data; it is not a formula source.
- Speciation: As and Hg concentrations are total/unspecified measurements. Risk calculations estimate inorganic arsenic fractions and methylmercury relevance, but the measured concentration table is not speciated iAs or MeHg.
- Market/geography: this is a local polluted-area dataset from Southern Italy and should not be pooled silently with general-market US or EU benchmark data.
