Summary
This study assessed cadmium (Cd) intake in an average Italian diet, finding weekly consumption below the established safe limit. However, ongoing environmental cadmium pollution necessitates continued monitoring, especially for at-risk populations.
Area of Science:
- Environmental Science
- Food Safety
- Toxicology
Background:
- Cadmium (Cd) is an environmental pollutant found in food.
- Elevated environmental Cd levels can increase dietary intake.
- The FAO/WHO set a Provisional Tolerable Weekly Intake (PTWI) for adults.
Purpose of the Study:
- To estimate dietary cadmium intake in Italy.
- To compare intake levels with the established PTWI.
- To identify potential risks from environmental pollution and dietary habits.
Main Methods:
- Analysis of complete meals from a factory canteen representing an average Italian diet.
- Quantification of cadmium using Zeeman Electrothermal Atomization Atomic Absorption Spectrometry (ETA-AAS).
Main Results:
- Mean weekly cadmium intake was 222 µg (range 137-326 µg).
- Median weekly intake was 198 µg.
- Average daily intake was 32 µg (range 19-46 µg).
Conclusions:
- Italian dietary cadmium intake is currently within the PTWI.
- Continued environmental cadmium emissions require attention.
- Vulnerable groups with specific dietary habits need monitoring.
