| Abstract | Arsenic in drinking water is an established cause of lung, bladder and skin cancers in adults, and may also cause adult kidney and liver cancer. Some evidence for these effects originated from Region II of Chile which had a period of elevated arsenic levels in drinking water, in particular from 1958 to 1970. This unique exposure scenario provides a rare opportunity to investigate the effects of early-life arsenic exposure on childhood mortality; to our knowledge, this is the first study of childhood cancer mortality and high concentrations of arsenic in drinking water. In this paper, we compare cancer mortality rates under the age of 20 in Region II during 1950–2000 with those of unexposed Region V, dividing subjects into those born before, during or after the peak exposure period. Mortality from the most common childhood cancers, leukemia and brain cancer, were not increased in the exposed population. However, we found childhood liver cancer mortality occurred at higher rates than expected; for those exposed as young children liver cancer mortality between ages 0–19 was especially high: the relative risk (RR) for males born during this period was 8.9 (95% CI 1.7–45.8; p=0.009), for females the corresponding RR was 14.1 (95% CI 1.6–126; p=0.018), and for males and females pooled, the RR was 10.6 (95% CI 2.9–39.2; p<0.001). These findings suggest exposure to arsenic in drinking water during early childhood may result in an increase in childhood liver cancer mortality. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
