Physicochemical parameters and CCME (Canadian Council of Ministers of the Environment) Water Quality Index (WQI) were used to estimate the degree of pollution in the selected paper mills area in Bogura District of Bangladesh. Moreover, a public perception survey was conducted in the study area to illustrate the present scenario regarding paper mill effluent discharge. The analytical results revealed that the concentrations of TSS, EC, COD, BOD5, phenols, K, and NO3 – N were higher than the permissible limit, and the DO level was below the ECR 1997 standard. However, there was no concentrations of heavy metals exceeded the permissible level. The FTIR analysis showed the presence of several toxic pollutants, including lignin, phenol, and halo compound. The CCME WQI showed that sites S-1 and S-2 were ranked as marginal, while site S-3 was ranked as fair. The study observed that the discharge of untreated paper mill effluent has the potential to cause harm to aquatic life and the environment.","PeriodicalId":29792,"journal":{"name":"Journal of Chemistry and Environment","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83901403","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 catalyst was carefully characterized using various physical techniques, including transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDAX), UV-visible diffuse reflectance spectroscopy (DRS), Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS) , and X-ray diffraction analysis (XRD). The results clearly demonstrated that TiO2 exhibited outstanding efficacy in oxidizing Hg0 when exposed to UV light. This phenomenon was ascribed to the excitation of photoelectrons within the valence band, leading to their transfer to the conduction band, generating photo-induced electrons that acted as reactive agents responsible for converting Hg0 into HgO. Notably, the activity of TiO2 under UV-visible light was significantly lower compared to TiO2 under UV light. The overall findings indicated that TiO2 under UV light exhibited the highest removal capacity, measured at 31.74 µg/g, followed by TiO2 under UV-visible light at 25.91 µg/g, and TiO2 in the dark at 20.89 µg/g. The study underscores the promising potential of TiO2 photo-catalyst for effectively eliminating Hg0 contamination in natural gas.","PeriodicalId":29792,"journal":{"name":"Journal of Chemistry and Environment","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78449742","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}

Though, these oils are prone towards oxidative deterioration from manufacturing to transportation due to environmental exposure as well as storage conditions which result in generation of different types of oxidation products. The generation of primary and secondary products result in harmful impacts on human health and may also result in cardiovascular diseases in consumers. The mechanism of oxidative deterioration cannot be assessed easily due to complexity of the reaction under which it may take place. Different types of approaches have been proposed to determine the products generated as a result of oxidation so that safety for their user can be assured. Different types of analytical techniques can be employed in addition to chemical methods so that analysis of oxidative deterioration can be done completely. The proposed study is aimed to assess the oxidative stability of oils in addition to the factors which can influence oxidation of these oils under different conditions. This review also summarize the classical and advanced state of the art analytical techniques which has recently been developed in different possible ways and effectively can be employed for analysis of oxidative deterioration of edible oils.

This study aims to evaluate the sources and distribution of trace metals in the shallow aquifer water of the Ganges River basin in the Bangladesh area. A total of 40 groundwater samples were collected and investigated for 11 trace elements and some selected water parameters followed by sophisticated methods. The results presented that three metals, viz. Fe, Mn, and Pb crossed the limit of WHO standard in most of the samples (70-100%), representing severe human health hazards. Besides, the samples are slightly acidic to basic and highly mineralized by divalent cations and bicarbonate because total hardness was found very high. To assess factors affecting the trace metal loads in groundwater samples and determine their possible sources and mobility, multivariate statistical techniques, including Pearson’s correlation coefficient, principal components analysis, and dendrogram cluster analysis are performed. Results revealed that sources of trace elements were identified to be geologic and little from human activities, i.e., application of agrochemicals, excess water mining, and industrial wastewater. It was recognized that the elevated concentration of trace elements in samples was caused by geogenic factors rather than manmade activities. Groundwater in this area poses a large threat due to high levels of trace metals, without any purification, it is essential to avoid this water for drinking. It advised that the groundwater quality should be constantly monitored for sustainable water quality management in the study zone.","PeriodicalId":29792,"journal":{"name":"Journal of Chemistry and Environment","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86745329","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 addition to chemotherapy advanced treatment techniques are also used in clinical practices, and they have an excellent healing results by enhancing patient survival rates. The social care net faces serious challenges because of the lack and high cost of modern therapeutic techniques. The side effects of chemotherapeutic drugs and expensive advance techniques triggered the patient interest towards phytochemicals drugs which indicate that nature always attracts human to fulfill their medical needs at very low cost.\u0000The pharmaceutical industries are showing strong interest in recent research, which has led to the addition of a quite large number of phyto-medicines in PCa therapeutic practices. Currently, several experimental epidemiological and clinical research reports confirmed that plant bio-actives play a significant role in PCa prevention by using different mechanistic ways such as suppressing adhesion, anti-angiogenesis, pro-apoptosis, anti-proliferation, invasion and migration.
