The challenge of managing biomedical Waste (BMW) in India has become more complicated in recent years, mainly due to the sudden emergence of COVID-19. As a methodology, a literature review was carried out with the help of Google Scholar, Research Gate, PubMed, and academic journal databases. Additionally, publications from numerous non-academic sources (such as news websites etc.) and current guidelines, such as those from the Ministry of Health and Family Welfare, Government of India, were also accessed. The review study identifies that PPE (Personal Protective Equipment) made up the majority of biomedical waste, followed by vaccine waste, during the peak of the COVID-19 vaccination campaign. The increase in PPEs such as face masks, aprons, face shields, gloves, goggles, and sanitizers, as well as other medical waste like bandages, plastic containers, syringes, testing kits, and tissues, has significantly changed the makeup of the BMW. This pandemic has hampered the proper management of solid waste, which has now surfaced as a major threat to developing countries. In this paper, biomedical waste management strategies followed in India and its disposal methods, cost-effective and environment-friendly methods to treat medical waste are also discussed.","PeriodicalId":101307,"journal":{"name":"Environmental analysis, health and toxicology","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136293887","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}

However, there has been an increasing report of chronic use with lethal effect. Among the commonly used herbal/ medicinal plants were ginger, garlic and lemon. These were seen to be prevalent across continents with brewing and crude extraction being the most means of consumption. This study investigated the organ wide toxicity of this extract following chronic consumption of crude extract. Twenty-five albino Wister rats, five in each group were used for this experiment. Each animal received 0.5ml/kg body weight of either ginger extract, garlic extract, lemon juice, or a mixture of equal volumes of all three extract (v/v) respectively twice daily for seven (7) days. Statistics were represented as ±SE; P≤0.05 was considered significant. Previous studies have shown that moderate consumption of these medicinal plants were beneficial and have shown no deleterious effect. This study observed no change in the weight of the experimental animals. The weight of the animals continued to increase except for the group that received lemon and the mixture, but these were not significant. It was observed that chronic consumption induced organ wide toxicity to include the liver, kidney, intestinal epithelium, stomach, and pancreas. These were shown to alter tissue architecture and the cell morphology. Packed cell volume was reduced in the lemon and the group that received a combination of all extracts (p=o.03). Blood differentials showed changes in levels. An elevated basophil level was observed in ginger and garlic (p<0.0001; p=0.0006). Monocyte levels increased progressively across each group when compared to the control with the most elevated level seen in the group that received the mixture (p<0.0001). Lymphocyte count was reduced across all the groups that received the extract except for animals that received ginger. This study suggests the application of caution among users of these medicinal plants and continues to draw attention to the need for harmonization and standardization of safe use doses.","PeriodicalId":101307,"journal":{"name":"Environmental analysis, health and toxicology","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76318098","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}

Concentrations of Pb, Cd, Cr, Cu, Ni, Zn and Al in wild mushrooms collected from the Nigerian environment were measured using atomic absorption spectrometer. Also, systematic analysis of articles on metal accumulation in mushrooms from Nigeria were obtained from scientific databases. Using hazard model indices, the metal concentration in mushrooms were evaluated for their potential carcinogenic and non-carcinogenic health risk when consumed by adults and children. Zn and Cd, respectively, had the highest and lowest mean concentrations (mg kg-1) in the analysed mushrooms from the field study, while Fe and Co, respectively, had the highest and lowest mean concentrations (mg kg-1) in the systematically reviewed articles. In the field study, the percentage distribution of THQ of the heavy metals greater than 1 was 0% and 42.85% for adults and children respectively. While for the systematic study, 30% and 50% of the heavy metals for adults and children respectively exceeded the limit of 1. The hazard indices obtained from both the systematic and field studies for both age groups were all >1, indicating significant health risk. The findings from both the systematic and field studies revealed that consuming metal-laden mushrooms by adults and children increases the carcinogenic risk to Cd, Cr, and Ni since they exceeded the acceptable limit of 1E-04 stated by USEPA guideline. Based on the findings from the systematic and field studies, it suggests that consuming mushrooms collected from metal polluted substrates increases carcinogenic and non-carcinogenic health risk among Nigerians.","PeriodicalId":101307,"journal":{"name":"Environmental analysis, health and toxicology","volume":"20 1","pages":"e2023013-0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75295646","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}

This paper aimed to show the impact of carrots on the toxic effect of AP on the livers of adult rats (female). To investigate some biochemical and histopathological changes effects of AP in rats, sixty white female rats were equally divided into four groups, the first group (G1) was administered orally with 3mg/kg/ body weight of AP, the second group (G2) was orally treated with AP and 10% carrot extract at the same time. The third group (G3) administrated 10% carrot extract only. The fourth (G4) group was the negative control and was treated with distilled water only. The experiments continued for a month at the animal house of the Veterinary Medicine College of Baghdad University. The results revealed that high levels of liver enzymes and bilirubin were induced in G1 with decreasing total protein levels. The pathological examination revealed the presence of marked proliferation of Kupffer cells in G1 livers. However, the G2 group showed slight infiltration of lymphocytes in sinusoids. The pathological changes in the livers of G3 group showed slight cloudy swelling in hepatocytes compared with the normal texture of hepatocytes in G4. The data of this experiment showed that treatment with carrot extract significantly decreases the elevation in the level of liver function enzymes in animal poisoned with AP. In addition, treatment with carrot extract reduces the severe damage in the hepatic tissue that occurred in rats treated with AP only. In general, it could be concluded that treatment with carrot extract provides a remedial effect against the hepatotoxicity that is resulted from exposure to AP.","PeriodicalId":101307,"journal":{"name":"Environmental analysis, health and toxicology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78795092","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}
