This study was conducted to assess the suitability of the ricemill wastewater being discharged into River Benue. Wastewater was sampled from point of discharge (sampling point A) and 20 meters away from the final entry into river Benue (sampling point B). Standardized methods were employed to analyze biochemical oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total heterotrophic count (THC), nitrate, phosphate, sulphate and pH in the sampled wastewater. Results were generated and compared with permissible standards Results generated from the analyses indicate that in sampling point A, pH ranged from 4.28 to 5.23, TDS ranged from 1478 - 1615 mg/L while THC ranged from1540 - 1600 cfu/ml. In point B, (BOD) ranged from 4.8 - 3.6 mg/L, (COD) ranged from 4.1 - 3.1mg/L, (TDS) 586 - 348mg/L, (THC) 608 - 512 cfu/ml and pH 7.32 - 6.43. Considering these results, (TDS), (THC), nitrate and THC were above permissible limits of World Health Organisation (WHO) and National Environmental standards and regulations Enforcement Agency (NESREA) respectively. Owing to these results, treatment measures and regulatory policies are suggested with a view to checkmating the abuse of river Benue through indiscriminate disposal of wastewater so as to avert imminent dangers it might likely pose to aquatic ecological system.","PeriodicalId":8854,"journal":{"name":"Biological Environment and Pollution","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75185177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to test the content of microbial and formalin contamination in the flesh of T. obesus fish from the Fish Auction Place (TPI) and Mobile Fish Trader (PIK) in Panimbang Village, Pandeglang, Banten. The research was carried out at the Regional Technical Implementation Unit (UPTD) Testing and Application of Quality of Fishery Products, Department of Marine Affairs, and Fisheries of Banten Province. This research is a descriptive laboratory study with purposive sampling. Twelve samples of T. obesus fish obtained from TPI (6 fishes) and PIK (6 fishes) were taken for 25 g of meat. The tested for microbial contamination content with Total Plate Count (TPC) using Butterfield's phosphate (BFP) media, and Plate Count Agar (PCA), Coliform-Test, and E. coli-Test using Lauryl Tryptose Broth (LTB). Brilliant Green Lactose Bile (BGLB), EC Broth and Levine's Eosin Methylene Blue (LEMB), and Formaldehyde-Test using Formaldehyde-Test Kits. The results showed that the flesh of T. obesus fish contained microbial contamination with the average values of TPC, Coliform MPN, and E. coli MPN, respectively, namely 1.6 103 colony/g, 15.2 MPN/g and < 3 MPN/g ( TPI), and 1,7103 colony/g, 61.3 MPN/g and < 3 MPN/g (PIK). Therefore, fish in TPI and PIK are safe for consumption as stipulated in SNI.","PeriodicalId":8854,"journal":{"name":"Biological Environment and Pollution","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86165653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the long term, waste is disposed of directly into the environment which can damage aquatic ecosystems and harm human health. Textile wastewater has a complementary picture and has a deep color. One of the most dangerous heavy metals contained in textile waste is hexavalent chromium (Cr(VI)). Several ways can be done to reduce hexavalent chromium (Cr(VI)) by bioremediation. Based on the results of the literature review, it shows that the bioremediation agents from single isolate microorganisms that are most effective in degrading chromium with high efficiency are Bacillus subtilis and Pseudomonas aeruginosa. The most effective consortium servers with constant reduction rates are the consortium of bacteria genus Mesophilobacter, Methylococcus, Agrobacterium, Neisseria, Xanthobacter, Deinococcus, Sporosarcina, and Bacillus by reducing BOD levels by 85.71%. The hexavalent chromium-degrading microorganisms are characterized by the presence of chromate reductase enzymes, mostly gram-negative bacteria, and a high growth rate.","PeriodicalId":8854,"journal":{"name":"Biological Environment and Pollution","volume":"120 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89372302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
