Trace elements in tissues from New Zealanders: a compilation of published data

Area of Science:

• Environmental Science
• Toxicology
• Human Health

Background:

• Limited data exists on trace element concentrations in New Zealand autopsy samples.
• Understanding these levels is crucial for environmental monitoring and public health assessments.

Purpose of the Study:

• To review and consolidate available data on trace element concentrations in New Zealand autopsy material.
• To compare these levels with international findings.

Main Methods:

• Literature review of studies reporting trace element concentrations in human autopsy tissues from New Zealand.
• Compilation of data for elements including copper, manganese, zinc, selenium, cadmium, nickel, lead, arsenic, bismuth, cobalt, mercury, silver, and thallium.

Main Results:

• Trace element data is available for various tissues across fetuses, infants, and adults.
• Selenium (Se) levels were markedly lower, and copper (Cu) levels were at the lower end of the adult range compared to international data.
• Concentrations of zinc, manganese, cadmium, nickel, lead, arsenic, bismuth, cobalt, mercury, silver, and thallium were generally similar to those reported globally.

Conclusions:

• New Zealand autopsy material shows generally comparable trace element levels to international data.
• Specific attention should be given to lower selenium and copper levels observed in the New Zealand population.
• Further research may be warranted to investigate the reasons for observed differences in Se and Cu levels.
