Abstract: The present study revealed the chromium toxicity and its health measures in L. rohita from the Yamuna river at Mathura- Agra region. Samples were taken in triplicate from both sites i.e. Vrindavan (Bihar ghat) and Agra (Renuka Ghat). The study was carried out on Four different organs (i.e. gills, muscles, liver, and kidney) of the fish sample. The sampling was done from Oct 2018 to January 2020. Chromium concentration in different organs of the fish was analyzed by Atomic absorption spectrophotometer(AAS). The average Cr concentration in gills was highest (9.64  mg/l) at the Mathura site followed byAgra sites (7.78 mg/l) for the month of April 2019. The concentration of Cr was highest in samples taken in the month of April 2019 and it was lowest in October 2018. The significantly high Cr concentration values were observed in the Mathura region than the Agra region for both seasons. In all samples, Cr concentration was above the standards stated by WHO except in the Kidney. In the present study, the bioaccumulation factor showed the chromium concentration in the tissues followed the order of gill > liver > muscle > kidney. HPI, MQI, and Pearson’s correlation coefficient analysis were also done in which HPI was observed very high and there was a positive correlation between all the samples.   Keywords:  Chromium, BCF, HPI, MQI, AAS, Fish Organs

We explore fish diversity and limnological status in the Yamuna River in Kalpi district, Uttar Pradesh, India. Several industrial and urban centers sit on the banks of the Yamuna in Uttar Pradesh. We selected four sampling stations on the Yamuna for purposes of fish fauna and water quality analysis over the course of a calendar year (October 2013 – September 2014). The samples were analyzed for selected physico-chemical analysis, and we recorded the types of fishes as well. We observed that most physico-chemical parameters were in a suitable range for the survival and growth of fish fauna. We recorded 29 species of fishes, belonging to 21 genera of 10 families.HYDRO Nepal JournalJournal of Water, Energy and EnvironmentIssue: 19Page: 57-62

Abstract Without immobilized hazardous waste contaminates soil and groundwater, which can further bio-accumulates and poses serious negative health impact on flora as well as fauna. The present investigation has been conducted to study of leaching behavior of chromium species in immobilized hazardous waste containing Basic Chrome Sulphate (BCS) dumped at dumping site Khanchandpur Kharanja, Rania, Kanpur Dehat district of Uttar Pradesh, India. Results indicated that the pH of sludge ranged from 10.16–11.90 while EC ranged from 840-16160 dSm-1 in a different layer of the dumpsite and significantly varies on increasing depth. A similar trend was also observed in TDS contents which strongly justified the leaching of salts in lower depth. Total Cr concentration (25029.94 mg kg-1) was observed in the top layer which was significantly increased on increasing depth i.e., 36102.0 mg kg-1 and 42811.77 mg kg-1 while TCLP based concentration ( 216.44 mg kg-1 in top layer) was significantly increased on increasing depth i.e., 406.25 mg kg-1 and 517.60 mg kg-1. A similar trend was also observed in total and TCLP hexavalent and trivalent (Cr6+ and Cr3+) chromium concentration. Hierarchical Cluster Analysis is separated all sample based on depth into three different cluster based on dissimilarity. A significant correlation was observed with TCLP Cr6+ in TCLP Cr3+, EC, and TDS at 0.01 levels while EC, TDS, total Cr6+, and TCLP Cr were significant correlated with TCLP Cr3+. The leaching behavior of Cr species was higher as well as increasing of depth in the dumping site.

  The red chili and turmeric powder available commercially in Lahore supermarkets which were randomly analyzed to evaluate the lead (Pb), and chromium (Cr) concentration by atomic absorption spectrometric technique. Lead and chromium were found to be in the ranges of 0.0050-0.01 ppm and 0.0430-0.1482 ppm, respectively. The mean concentration of lead in the red chili and turmeric powders were found to be 2.6 mg/Kg and 5.3 mg/Kg respectively, while that of the chromium was found to be 0.0419 mg/Kg and 0.1142 mg/Kg respectively. Levels of both these metals (lead and chromium) are  therefore lower in the red chili compared to the turmeric powder. Also, both the samples are comparatively rich in lead as compared to chromium.

The declining rate of Cr concentration in faeces after the dosage of a Sodium dichromate treated protein supplement can be used as an estimate of the protein outflow; rate. The experiment reported was planned to show wheter the variation in the rate of decline of Cr concentration in faeces induced by level of feeding and processing of the diet reflect the variation in rumen outflow determined by the rumen dilution rate of the marker.In a duplicate 3x3 square latin design, 6 mature ewes cannulated in rumen were fed a ground pelleted diet of ‘0.6 alfalfa hay and 0.4 barley grain at 1 or 2 x maintenance energy level (P1,P2) or the same proportions of chopped hay and -cracked barley offered in a loose mix at twice maintenance (Ch2). 50 g. of fish meal treated withsodium dichromate were given as a single dose after 15 days of adaptation period to the diet and faecal grab samples taken at 6,12,18,24,32,36,42,48,60, 72,96 and 120 h. A second dosage was given 7 days later and rumen samples withdraw-ned at 1,3,6,9,12,15,18,22,28,36,48,60 and 72 h.

The immunosuppressant tacrolimus has a narrow therapeutic window, necessitating therapeutic drug monitoring to maintain efficacy and minimise toxicity. There are very few reports examining the impact of impaired biliary excretion on tacrolimus blood levels or toxicity. We report the case of a 26-year-old combined liver and kidney transplant recipient, who developed acute biliary obstruction leading to tacrolimus toxicity with very high blood tacrolimus levels. Despite a careful evaluation, no alternative cause was found for her acute kidney injury, and her kidney function returned to previous baseline within several days following treatment of the biliary obstruction and temporary withdrawal of tacrolimus.

Abstract The Shahi ʿIdgah at Rapri (Uttar Pradesh), which dates to 1312, was built by Malik Kafur, the general of the Delhi sultan ʿAla⁠ʾuddin Khalji (1296–1316). The village of Rapri was part of Malik Kafur’s fief and an important station for the army, as it commanded a ford on the Yamuna River. ʿĪdgāhs, sometimes translated as “wall-mosques,” are extra-urban, open prayer spaces for accommodating large congregations during the two main religious festivals (ʿīds). The Rapri ʿīdgāh constitutes a major landmark in the architecture of the Delhi Sultanate, mainly because of its exceptional decoration of turquoise-glazed tiles, the oldest example of its kind still in situ. Although often considered a technique that originated in the Iranian domains, the making of glazed tiles was already known in the Kushan period (first to fourth century CE), and some findings have been excavated from Buddhist contexts in the nearby Mathura region. This study shows the link between the tiles of Rapri and later fourteenth century examples, and with glazed pottery.

Reduction and immobilization of Cr (VI) as Cr2O72- is investigated by using metakaolinite-based geopolymer complexed reductant. Without reductants, the leached Cr concentration from metakaolinite-based geopolymer containing Cr (VI) is very high. Adding reductants as FeCl2·4H2O, FeSO4·7H2O, and Na2S·9H2O respectively during geopolymerization, the leached Cr concentration is below 5 mg L-1 with high Cr immobilization rate above 99 %. By comparison with the immobilization of Cr (III), the added reductants reduced Cr (VI) to Cr (III) which can be locked successfully in the amorphous structure of geopolymer. Meanwhile, Cr (VI) initial concentration is lower than 0.7 wt. % in metakaolinite-based geopolymer, the above reductants can all meet the requirements. While for Cr (VI) initial concentration larger than 0.7 wt. %, Na2S·9H2O is more appropriate. Such a simultaneous reduction and immoboilization process enables the feasibility of using metakaolinite-based geopolymer complexed reductant to implement a one-step procedure for chromite ore processing residue cleanup.

River Chambal, in northwestern India, is a tributary of the Gangetic River system.  It flows through the states of Rajasthan, Madhya Pradesh (MP) and Uttar Pradesh (UP), and the National Chambal Gharial Sanctuary (NCGS) encompasses a 572km stretch of the river from Keshoraipatan in Rajasthan to Pachhnada in UP.  The sanctuary includes about 15km of river Yamuna after confluence with Chambal.  During annual monitoring of Gharial in Chambal the Indian Skimmer, Rhynchops albicollis numbers were also counted in 12 study zones for 17 observation years spread between 1984–85 and 2015–16.  The number of skimmers was below 355 for 15 of the 17 observation years.  Skimmer counts were higher in 1995 at 555 individuals.  The count for different study zones is not uniform, but with reference to Rajghat at the crossing of National Highway number-3, the count upstream is lower than downstream with an exception in the year 2011.  The river downstream appears to be a better skimmer habitat with better availability of fish, and long stretches of flowing water along low-lying sandy banks.  The study calls for continued, coordinated and strengthened attention to NCGS for added conservation of locally migrating birds.  The research and management connect in NCGS is a model where long term ecological monitoring has been possible because of simple and implementable protocols that were used unchanged over such a long period by a set of identified field personnel.
