Lead Clinical Trial
Official title:
A Prospective Observational Cohort Study Assessing the Feasibility of Measuring Serum Lead Levels in New Zealand Hunters Using Lead Projectiles
This is a clinical research protocol to determine the feasibility of assessing lead levels in
hunters who use lead projectiles. This study will determine if it is possible to perform an
interventional double-blind placebo-controlled study of lead levels in hunters using lead or
lead-free projectiles following consumption of self-harvested wild game. The hypothesis for
the subsequent study is that minute lead particles from shrapnel dispersed through the animal
during harvest are ingested and result in increased lead serum levels. This current
observational study establishes if this conclusive interventional study is possible through
establishing if hunters using lead projectiles in New Zealand have elevated lead levels after
eating animals harvested with lead projectiles. This study will be conducted in compliance
with the protocol, Good Clinical Practice Standards, associated regulations and institutional
research requirements.
This study aims to assess if hunters eating meat shot with lead projectiles experience
elevated lead levels. Hunters will be asked to provide blood samples 2-4 days after they eat
meat harvested with lead bullets and provide a subsequent sample when they have abstained
from eating wild game harvested with lead bullets. We have chosen to use deer as the species
for this study to reduce variation and New Zealand is the ideal place to conduct this study
because of year-round hunting of deer. This design will allows paired testing of subject lead
levels.
