Groundwater fluoride and health problem was meticulously studied for dental and skeleton fluorosis except few studies on urolithiasis. Urolithiasis is multi-factorial disease and excess fluoride consumption is one of the causal factors. In view of this, increase of fluoride in groundwater is reported in semiarid Deccan Volcanic Province (DVP), India. To understand the fluoride and urolithiasis association, present study was carried out in Karha river basin of DVP region. Three stages of data generation were adopted for present study such as procuring of medical records of urolithiasis, previous groundwater chemistry data and geochemical investigation of 50 groundwater samples from representative villages. Further, these variables were used for correlation analysis, temporal and spatial distribution to find out their relationships. Result shows medical records of hospitals indicating the gradual increase in urolithiasis is reported during drought situations. In temporal variation, annual fluoride concentration of groundwater and hot days are positively correlated with annual urolith patients as well as spatial study supports the same. In conclusion, present study highlights the relationship of urolith formation with number of hot days, groundwater electrical conductivity and fluoride. However, detailed biomedical study may lead towards understanding of fluoride- urolithiasis relationship.

Abstract The Deccan Volcanic Province (DVP) is significant for its eruption close to Cretaceous–Paleogene (K-Pg) boundary. Chemostratigraphy established in its western parts is the foundation of postulated long distance correlations across the province and consequential models of its eruptive history. A critical review of diagnostic parameters used to characterize stratigraphic units shows them to be probabilistic rather than deterministic and therefore, they are ambiguous. We compile the previously overlooked mapping into district-wise altitude-controlled logs across the province. A reappraisal of the chronological and paleomagnetic data for the DVP shows that volcanism was not concurrent across the province and questions the validity of previous correlations. This analysis also shows that at least three separate eruptive phases occurred in disparate parts of the province, spread over ∼7 million years, of which only one preceded the K-Pg boundary. We resurrect an eruptive model involving multiple eruptive centers and endorse a zonal stratigraphy for the DVP. This approach provides a better context for correlations than the prevailing stratigraphy that clubs the entire province into a single entity.
