A Critical Appraisal of Biomedical Waste Management in Uttar Pradesh
(Springer Science and Business Media Deutschland GmbH, 2022) Praveen Kumar Tiwari; Surendra Kumar Pandey; Rohit Kushwaha; Sonam; Kapil Malviya; Markandeya; Sheo Prasad Shukla; Devendra Mohan
Bio-medical waste is the waste generated from hospitals, including infectious waste, and has a high potential for causing injury and infections to humans as well as to the environment. Effective bio-medical waste management is the requisite parameter for a healthy and unpolluted environment. It is a social and legal responsibility of the medical community and common people to participate in the proper hygienic waste disposal actively and lead the environment free from various infectious diseases. BMW is precarious in the constitution and is different from general municipal waste; hence, it requires a unique approach and handling to avoid environmental and human health risks. The government of India made a statutory requirement for appropriate handling and disposal of bio-medical waste with the publication of gazette notification in July 1998 and further making required changes in it. This article explains various components, techniques for remediation, and consequences of improper disposal of BMW and provisions of BMW management in India. It also gives a brief overview of bio-medical waste management of hospitals in Uttar Pradesh. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
An overview of human health risk from opium alkaloids and related pharmaceutical products pollution in aquatic ecosystems

Fresh water is a valuable resource, but the increase in pollution of aquatic ecosystem is a matter of concern. Industries are rapidly budding in India, which discharge their effluents into the water bodies either directly or after treating partially. Pharmaceutical compounds are very important, but at the same time, release toxic contaminants in the environment. Pharmaceutical products impose huge effects on aquatic environment, resulting in acute and chronic damages, reproductive damage, behavioral changes, and inhibition of cell proliferation. The effluents produced from alkaloid processing industries is highly polluted having low pH, high COD, BOD5, sulfate, and TKN values, and a characteristic dark brown color. A number of physical as well as biological processes occurring in aquatic ecological unit may cause reduction of trace concentrations of pharmaceutical compounds. Treatment of wastewater generated from alkaloid processing is a challenging task because of the complex mixture of contaminants. Several methods for the treatment of these wastes, such as anaerobic and aerobic biological treatment, anaerobic treatment with membrane treatment, and aerobic treatment with catalytic wet air oxidation have been reported. Studies have also been conducted on physicochemical treatment in combination with activated sludge process. Membrane processes and Fenton oxidation have also been investigated as a post-treatment method. Membrane technologies are desirable for industrial wastewater treatment as no external addition of chemicals is required. © 2022 Elsevier Inc. All rights reserved.
