Still, contamination with potentially harmful metals due to natural processes and anthropogenic activities leads to various health impacts. The focus of this research was to determine the extent of metal contamination in shallow groundwater from three southwestern districts of Bangladesh and the health hazards associated with it. A comprehensive analysis of metal, including metalloid, copper (Cu), aluminum (Al), chromium (Cr), Arsenic (As), Manganese (Mn), and boron (B) was performed on a set of 51 samples. Groundwater samples were analyzed for contamination using Atomic Absorption Spectroscopy and a UV–VIS Spectrophotometer, with pollution levels assessed via indices like the Metal Evaluation Index, Nemerow Pollution Index, and Contamination Index. Human health risks were evaluated through Chronic Daily Intake, Hazard Quotient, and Hazard Index calculations following USEPA guidelines. The results indicate that arsenic levels exceeded 25 samples and manganese levels exceeded 34 samples in accordance with WHO drinking water standards. Boron (B) concentrations exceeded the threshold in seven samples, whereas Al, Cu, and Cr exceeded limits in only two samples. The metal evaluation index (MEI), Nemerow pollution index (NI), and degree of contamination (C<sub>d</sub>) revealed moderate to severe contamination in groundwater and unsuitability for drinking purposes.

Concentrations of As and Mn were identified as the main contributing factors to the higher HI values in both adults and children. However, the concentrations of Cu, Al, Cr, and B in groundwater were not individually found to be as risky.

Clinical reports of naturally occurring grass tetany in goats are least described in the literature and it is considered to be a rare disease. The present study documents the clinical manifestation and management of hypomagnesemia-associated excitatory neuropathy in two <em>Theileria</em> spp. infected Malabari goats presented to the small ruminant medicine OP unit of the University Veterinary Hospital and Teaching Veterinary Clinical Complex, Mannuthy, Thrissur, Kerala, India.</p></div><div><h3>Methods</h3><p>The first goat was in the last trimester of pregnancy and was showing signs of hyperesthesia, limping, difficulty in standing, and inappetence for the last six hours. The second goat was kidded six weeks back and was showing recurrent epileptic seizures and hyporexia from the previous day. Both the goats were kept on extensive grazing from the forest areas with unidentified lush vegetation. On clinical evaluation, both the goats were showing persistent excitatory neurological signs. Fecal examination, peripheral blood smear examination, PCR screening panel for hemoparasites, Complete Blood Count, and serum levels of calcium, magnesium, and glucose were evaluated.</p></div><div><h3>Results</h3><p>A significant reduction in serum magnesium levels was noted in both cases along with the varied glucose levels. <em>Theileria</em> spp. infection was noticed in blood smear examination and confirmed by PCR. The goats responded well to the therapy using MIFEX™ and other supportive medications and showed uneventful recovery.</p></div><div><h3>Conclusion</h3><p>It is suggested that the farmers should be vigilant enough while allowing goats to graze in unknown vegetation and prevent indiscriminate fodder intake during periods of drought. This is the first documented report of hypomagnesemic excitatory neurologic symptoms in <em>Theileria</em> spp. infected periparturient Malabari goats and showing response to appropriate therapy.</p></div>","PeriodicalId":73997,"journal":{"name":"Journal of trace elements and minerals","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773050624000776/pdfft?md5=ea3551b2b1cc80c0d5371197f8ba8355&pid=1-s2.0-S2773050624000776-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
