Assessment of groundwater and surface water quality along a river is important as it directly affects the agricultural, industrial activities and population. The objective of the study is to assess ...the quality of the Cauvery river water and adjacent groundwater for drinking and irrigational purposes and to identify the infuence of geogenic and anthropogenic sources. Groundwater and surface water samples were collected along the course of the river at approximate intervals of 25 km. The samples were analysed for electrical conductivity, pH, sodium, calcium, magnesium, potassium, bicarbonate, chloride and sulphate. Sodium was identified as the dominant cation and bicarbonate was the dominant anion for both river water and groundwater. These values were compared with limits recommended by the Bureau of Indian Standards for drinking purposes. The total dissolved solids were found to exceed the permissible limits for drinking water in most of the groundwater samples, and it was below the permissible limits in river water samples. Most of the river water samples were found to be suitable as per the drinking water quality standards, but most of the groundwater samples were unsuitable based on the concentration of major ions. Irrigation water quality was also assessed based on magnesium hazard, residual sodium carbonate, sodium percentage, sodium adsorption ratio, permeability index and salinity hazard. Most of the river water samples collected were suitable for irrigation, whereas most of the groundwater samples collected were doubtful for irrigation based on residual sodium carbonate and sodium percentage. Drinking water and irrigation water quality indices were also computed to assess the characteristics of water. Groundwater quality in locations nearer to the confluence of tributaries and industrial areas was of poor quality, while both river water and groundwater near the coast were poor, both for drinking and irrigation purposes. Comparison of the dissolved load with other rivers of the world was also made, which reveals that the Cauvery River yields comparatively higher dissolved load per area than most of the rivers. The chemical load in the river is due to natural and anthropogenic sources. Therefore, it is necessary to enforce the existing norms for the discharge of treated effluents by industries and townships along the river so as to reduce the chemicals contributed by anthropogenic sources.
Disposal of industrial waste is of great concern because it releases toxic metals resulting into the degradation of environments and consequently causes health effects on humans. The present study ...was carried out with the objectives of identifying the possible source and migration of contaminants in the surface water and groundwater and the associated health risks in the industrial region of Ranipet, Tamil Nadu, India. A total of 22 water samples were collected and analysed for the concentration of major ions and trace elements. Chemical speciation of chromium and lead in surface and groundwater was calculated using the geochemical code, PHREEQC. The concentration of total dissolved solids, chromium and lead was high in the surface water than groundwater in this region. The chromium in most of the sampled water is dominated with Cr(OH)

and Cr(OH)

species and the dominant species of lead was PbCO

. The major source of contamination is the waste dumped in this region and also the improper disposal of effluents from the small-scale industries in this region. Use of groundwater with the present level of chromium and lead in this region will cause several health effects through oral and dermal pathways. Hence, stringent monitoring of quality of water sources of this region, enforcement of regulation of the disposal of wastes from the industries, recover and treat the dumped solid waste are very much necessary to prevent the spread of contamination.
Abstract Rosai-Dorfman disease (RDD) is a rare benign proliferative disorder. Lymph nodes are the usual and common sites of involvement. Involvement of the extranodal site is also documented in the ...literature. 18F-fluorodeoxyglucose positron emission tomography computed tomography (F18-FDG PET CT) is a valuable whole-body imaging modality in staging and treatment response of various lymphoproliferative and solid organ malignancy. Similarly, PET CT survey can detect the involved sites of various body systems, infective or inflammatory diseases, and provide guidance for biopsy and to reach to diagnosis. Here, we present a case of RDD, who presented with neurological manifestations and on F18-FDG PET CT, diagnosed with multiorgan involvement.
Angular pregnancy, a rare condition, marked by implantation positioned medially to the uterotubal junction within the lateral angle of the endometrial cavity poses a risk of severe complications, ...such as uterine rupture, placental retention, postpartum hemorrhage, and even necessitating hysterectomy, all of which can be fatal. Distinguishing angular pregnancy from other emergent conditions, particularly interstitial and cornual pregnancies, is crucial due to similar presentations and difference in embryo viability, risk, and management. While angular pregnancies can progress to term, they are associated with an elevated complication rate. Here, we present a case of primigravida with angular pregnancy who opted for evacuation under hysteroscopic guidance subsequent to unsuccessful pregnancy.
