ABSTRACT Hair analysis can be used to measure environment exposure over a long-term period, or to study ailments like hypertension, heart disease, epilepsy and others. This examines the metal content in hair and investigates some of the major factors that affect the metal content in hair. Then using statistical correlation tests to investigate the relationships of the factors to one another and affect the trace metal content in hair. 504 participants from Sudbury and the surrounding area provided hair samples from the nape of the neck and completed questionnaires requiring information about their health status, area of residence, nutrition, hair status, age, gender and other factors. The hair strands were then digested and the metal content was measured by ICP-MS. It was found that metal content was higher in females relative to males and it may be possible to track these differences to biochemical changes such as menstruation. It was also found that Mg, Cr, and Cu varied with age. Cr in hair correlated with prevalence of cancer, heart disease and hypertension (p<0.01). Correlations were also found with respect to area of residence and is it related to environmental exposure.

Considering the importance of the healthy coral reef ecosystems to Langkawi’s economy as well as to the global coral reef biodiversity, the present study provided the baseline database regarding on distribution of heavy metals concentration (Cd, Cu, Pb) and the trend of heavy metals accumulation in Diploria Labyrinthiformis and Favia Pallida corals at Pulau Langkawi region. This report showed the level of heavy metal contamination in each of 5 years growth rate bands in both coral specie susing AAS. The averages of heavy metals concentration in Diploria Labyrinthiformis were 0.018±0.002 mg/L, 0.044±0.11 mg/L, and 0.120±0.01 mg/L for Cd, Cu, and Pb respectively. Meanwhile the concentrations of heavy metals for Favia Pallida were 0.017±0.02 mg/L, 0.088±0.004 mg/L, and 0.218±0.14 mg/L for Cd, Cu, and Pb respectively. Both species showed the low concentration and not exceeding the MPI safety level that indicated that the corals were not impacted by pollution. The trend and correlationships of the Cd, Cu, and Pb in the bands coral slab showed the increasing trend of concentration which were increased gradually from the surface (youngest) to bottom (oldest) layer for the samples.
