| Abstract | Chronic exposure to combined fluoride and arsenic continues to be a major public health problem worldwide, affecting thousands of people. Although there have been reports in the literature about the toxicity of arsenic and fluoride individually, there is very little known about the combined effects of these two elements. The participates were selected from people living in fluoride–arsenic polluted areas due to burning coal. By observing the changes of renal function biomarkers, the results show that fluoride and arsenic can induce glomerular and tubular injury. For the observed exposure levels, the combined effect of fluoride and arsenic on renal function is mainly one of antagonism. Moreover, the benchmark dose and its lower confidence limit were calculated to estimate the exposure limits for urine arsenic (UAs) and urine fluoride (UF). The results indicate that the critical concentrations of UF and UAs for renal function injury were estimated, respectively, to be 0.54 mg g−1 Cr and 10.50 μg g−1 Cr in a population co-exposed to fluoride and arsenic; and urine albumin can be used as a relatively sensitive biomarker of renal function. |

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.
