Probabilistic Assessment of Geogenic Arsenic Exposure and Attributable Health Risks

Project overview

Soluble  inorganic  arsenic  is  acutely  toxic  as  the  ingestion  of  large  doses  leads  to gastrointestinal symptoms, disturbances of cardiovascular and nervous system functions, and eventually death. Long-term arsenic exposure through drinking-water can increase risks of cancer in the skin, lungs, bladder and kidney, as well as other skin changes such as hyperkeratosis and pigmentation changes. In South and East Asia, an estimated 60 million  people  are  at  risk  due  to  excessively  contaminated  groundwater  sources  by arsenic as the current data showed that at least 700,000 people in the region have so far been affected  by  arsenicosis.  To develop the arsenic mitigation strategies for arsenic affected region, there is  a  dire  need  to  undertake  exposure risk  assessment  based  on  multiple  levels  of anthropogenic and natural occurring arsenic.


The project is aimed to use exposure risk assessment and predictive modelling approaches to assess the attributes of arsenic towards development of various types of arsenic associated health complications.
