TY - JOUR ID - citeulike:5979037 L3 - citeulike-article-id:5979037 N2 - Indigenous people of the Torres Strait Islands have been concerned about the safety of their traditional seafoods since the discovery of high cadmium levels in the liver and kidney of dugong and turtle in 1996. This study explored links between urinary cadmium levels and consumption frequency of these traditional foods and piloted a community-based methodology to identify potential determinants of cadmium exposure and accumulation. Consultations led to selection of one community for study from which 60 women aged 30 to 50 years participated in health and food frequency survey, urine collection and a routine health check. Urinary cadmium levels were determined by inductively coupled plasma-mass spectrometry; data were analysed using SPSS-14. The geometric mean cadmium level in this group of women was 1.17 (arithmetic mean 1.86) microg/g creatinine with one-third exceeding 2.0 microg/g creatinine. Heavy smoking (>or=300 pack years) was linked to higher cadmium in urine, as was increasing age and waist circumference.
