- Abstract
This study was carried out to investigate biological and statistical nature of arsenicosis risks on a severely arsenic (As) affected population in the Banglish village in Comilla district of Bangladesh. Subject's hair As and vegetables As levels were estimated by PIXE method, and arsenicosis status of the subject was examined by a physician. Arsenicosis was found in 45% female and 61% male subjects. Arsenic levels > 0.50 ppm showed greater arsenicosis risks that significantly varied with subject's sex and age. Unlike children, young (≥10 years) to middle aged (~49 years) population were significantly affected by arsenicosis. Logistic regression model analysis showed that arsenicosis risks are not only the devastating toxicity of As accumulation in human body through ingestion of contaminated drinking water, but the summation of all sources of As accumulation. Human hair As levels were found as the biomarker ranging from 0.03-8.3 μg/g in stage I arsenicosis patients, and from 1.1-56.9 ppm in the stage II patients up to 49 age. Hair As level was declined to 2.2-25.5 ppm at > 49 aged population. The findings inferred that groundwater As affecting the public health through contaminating total environment, that in turn posing an alarming situation in the study area.
