Latest ArticlesSince the implementation of the State administration for market supervision and administration's Measures for the Administration of the Qualification of Inspection and Testing Institutions (Order No. 163) amendment and Measures for the Supervision and Administration of Inspection and Testing Institutions (Order No. 39) in 2021, regulatory authorities at all levels have significantly intensified their efforts in conducting random inspections and targeted rectification campaigns. Cases of inspection and testing agencies being stripped of their qualifications, suspended, fined, or publicly reprimanded have frequently appeared in the media, attracting significant attention from the industry. As inspection and testing agencies, it is imperative to enhance their quality compliance management capabilities, thoroughly study and understand various regulatory policies and cases, and strengthen internal quality compliance management to mitigate the risk of administrative penalties, thereby boosting the confidence of all sectors of society in the industry. This article first introduces the necessity and urgency of introducing a quality risk management mechanism in laboratories. It then describes various sources of risk. Finally, it elaborates on the planning, implementation, performance evaluation, and improvement of the quality compliance risk management mechanism in laboratories, aiming to help readers initially grasp and understand the basic approach to implementing quality compliance risk management in laboratories.
University laboratories play a crucial role in technological innovation, talent cultivation, achievement transformation, and enhancing comprehensive national strength, but at the same time, they have also become prone to safety accidents. The lack of safety awareness, safety willingness, safety knowledge and skills among student groups is a common problem among current university students. In addition, the safety characteristics of medical university laboratories involve more chemical and medical aspects. Therefore, analyzing the current status of laboratory safety education in medical universities, based on the concept of "three pronged education" in the context of "new medicine" construction, this paper explores how to build an integrated safety education system and diverse implementation paths for schools, colleges, and laboratories from the perspectives of all staff, the whole process, and all aspects.
ABSTRACT: With the rapid advancement of industrialization and urbanization, a series of new pollutants, such as drug residues, personal care products, and industrial chemicals, have gradually emerged. These pollutants pose a serious threat to the ecological environment and human health due to their low concentration, high toxicity, easy bioaccumulation, and environmental persistence. New pollutants, as a type of environmental pollutant that has recently been identified or begun to receive widespread attention, are characterized by their low content but significant toxicity. Among them, the problems of new pollutants such as microplastics, antibiotics, and environmental endocrine disruptors are particularly prominent. How to efficiently identify and monitor these pollutants has become a core concern for researchers in the field of environmental science. This article will deeply analyze the characteristics, hazards, and monitoring difficulties of new pollutants, and summarize the latest research trends in the field of environmental monitoring, especially the detection technologies for pollutants such as microplastics, antibiotics, and environmental endocrine disruptors. By comparing the advantages and disadvantages of various monitoring methods, guidance is provided for environmental workers in selecting appropriate monitoring methods, in order to achieve rapid and accurate identification and monitoring of new pollutants.
Objective To explore the comprehensive quality evaluation of Panax notoginseng based on high performance liquid chromatography (HPLC) multi-component quantification combined with grey relational analysis. Methods HPLC was used to simultaneously determine the contents of notoginsenoside R1, ginsenoside Rg1, Re, Rb1, and Rd in Panax notoginseng samples from different origins and different commercial specifications. A comprehensive quality evaluation model was established by combining the grey relational method. Results The established method simultaneously determined the contents of notoginsenoside R1, ginsenoside Rg1, Re, Rb1, and Rd, with good methodological investigation results. The grey relational method could distinguish between samples from authentic origins, qualified samples, and unqualified samples. Conclusion The fusion model of HPLC multi-component quantification and grey relational analysis was constructed to accurately evaluate the quality of Panax notoginseng, providing a scientific evaluation basis.
