Hypothesis
Does lead exposure induce copper deficiency in humans?
Conclusion
The relationship between lead exposure and copper deficiency in humans remains unclear and requires further investigation.
Supporting Evidence
- Animal studies show lead ingestion decreases blood copper levels.
- Some studies found decreased SOD activity in lead workers, but results are inconsistent.
- Few studies have examined the effects of copper on PON1 activity.
Takeaway
This study talks about how lead might affect copper levels in people, but we don't know for sure if it does.
Limitations
The study did not measure plasma copper levels or other related factors in the cohort.
