Hypothesis

The study aims to determine target hazard quotients (THQ) from literature reports giving empirical levels of metal ions in table wines.

Conclusion

The THQ values calculated are concerning in that they are mainly above the safe level of THQ<1.

Supporting Evidence

  • THQ values for wines from Italy, Brazil, and Argentina were lower than those from other countries.
  • Hungarian and Slovakian wines had THQ values reaching 300.
  • THQ values for a sample of red and white wines ranged from 30 to 80 for females based on a 250 mL glass per day.

Takeaway

This study found that many wines have dangerous levels of metal ions that could harm your health if you drink them regularly.

Methodology

THQ values were calculated from reported concentration ranges of metal ions in wines from various countries.

Potential Biases

The study does not account for cross effects with other potential toxins or the effects on different age groups.

Limitations

THQ values do not reflect genetic predispositions to disease or the effects of binge drinking.
