Questioning the Cardiovascular Effects of Nickel
Author Information
Author(s): Michael D. Dutton
Primary Institution: CVRD Inco Limited
Hypothesis
Are elevated nickel concentrations in air pollutants responsible for cardiovascular effects?
Conclusion
The study suggests that local sources of nickel, rather than emissions from a distant smelter, are likely responsible for the observed nickel levels in Tuxedo, New York.
Supporting Evidence
- The nickel concentrations in ambient air were found to be similar to those in New York City.
- Local sources of nickel emissions are likely significant contributors to the levels observed in Tuxedo.
- Historical data shows no cardiovascular risk factors associated with nickel after extensive monitoring.
Takeaway
The study says that the nickel in the air near New York City likely comes from nearby sources, not from a faraway factory.
Methodology
The authors analyzed air pollution data and back trajectory analyses to assess nickel sources.
Potential Biases
The author is employed by a company related to the subject, which may introduce bias.
Limitations
The study relies on the accuracy of back trajectory analyses and does not account for all potential local sources of nickel.
