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 study the method of laboratory Brucella detection and evaluate its clinical efficacy. Methods The clinical case of Brucella infection in sheep diagnosed by medical staff in our hospital in March 2019 was taken as the research object. The advantages and disadvantages of serum agglutination test, routine blood culture and bacterial identification, and mass spectrometry identification methods in diagnosing Brucella were analyzed and discussed, providing some reference for the detection of Brucella in grassroots hospital laboratories. Results The medical staff's serum brucellosis tiger red plate agglutination antigen test was positive. The blood culture BD PhoenixTM whole bacterial identification/drug sensitivity system instrument in the United States indicates that the aerobic bottle reports positive, but cannot identify the species of Brucella. The mass spectrometer identified it as Brucella lamblia. Conclusion The above methods have their own advantages and disadvantages in application, grassroots hospital laboratories should choose suitable methods for detecting Brucella based on actual conditions.

Objective To investigate the interference effect of lipid turbidity on the detection of prealbumin by Immunotransparency turbidimetry. Methods 40 non-lipid turbidity serum samples from patients with cholesterosis cutis were selected from February 2021 to January 2024 in Shanghai Fengxian District Dermatology Prevention and Control Institute, an additional 40 samples of turbid serum from patients with xanthelasma were selected. Immunotransmission turbidimetry was used to measure prealbumin levels in 80 serum samples, and then the method repeatability of 40 serum samples without lipid turbidity was analyzed, and the lipid turbidity interference effect of 40 lipid turbidity serum samples was analyzed. Results The intra-batch precision of prealbumin was less than 1/4TEa (CLIA’88), and the total precision was less than 1/3TEa (CLIA’88). There was no significant difference in prealbumin in 40 fat-free turbid serum samples after low-speed centrifugation and high-speed centrifugation followed by immunotransmission nephelometry, respectively$\left({P >{0.05}}\right)$. Lipid turbidity did not interfere with the accuracy of prealbumin detection in blood samples treated by high-speed centrifugation. For blood samples treated by low-speed centrifugation, when the lipid turbidity index was$<{43}\mathrm{{mg}}/\mathrm{{dL}}$, it did not interfere with the effect of prealbumin examination, and when the lipid turbidity index was$\geq {43}\mathrm{{mg}}/\mathrm{{dL}}$, it interfered with the effect of prealbumin examination. The detection result of prealbumin in blood samples treated by high-speed centrifugation was higher than that of low-speed centrifugation samples$\left({P <{0.05}}\right)$. Conclusion Lipid turbidity interferes with the accuracy of albumin level before immunotransmission turbidimetry, but the interference effect of mild lipid turbidity is not significant. When the lipid turbidity index is$\geq {43}\mathrm{{mg}}/\mathrm{{dL}}$, the interference effect on prealbumin is obvious.
Objective To investigate the interference of calcium dobesilate on the urine total protein determination test kits (turbidimetric method) and the anti-interference method. Methods (1) According to the national standard WS/ T 416-2013 Interference Test Guide, low, medium, and high concentrations of urine matrix were used to prepare calcium dobesilate interference samples of different concentration gradients, and the urine total protein concentration was detected using the urine total protein determination test kits (turbidimetric method) of Dirui and Roche two factories. The relative deviation between the interference sample and the reference control sample was calculated.(2) The urine matrix was prepared at low, medium, and high concentrations, and the$0\mathrm{{mmol}}/\mathrm{L}$and$1\mathrm{{mmol}}/\mathrm{L}$calcium dobesilate interference samples were prepared using different wavelengths. The urine total protein concentration was determined using the urine total protein determination test kits (turbidimetric method) of Dirui and Roche two factories, and the relative deviation with respect to the${505}\mathrm{\;{nm}}$measurement wavelength was calculated. Results (1) When the calcium dobesilate concentration was${0.4}\mathrm{{mmol}}/\mathrm{L}$, the deviation of the urine total protein detection results in the low and medium concentration urine matrix began to deviate significantly from the acceptable interference range, and the degree of interference on urine total protein detection increased as the calcium dobesilate concentration increased. At the same drug concentration, the greater the urine total protein concentration was, the more obvious the interference was.(2) When the test wavelength was${800}\mathrm{\;{nm}}$, the interference of calcium dobesilate on the Dirui and Roche turbidimetric method urine total protein test kits could be significantly reduced, and the deviation of interference was within the acceptable interference range. Conclusion Calcium dobesilate can produce varying degrees of negative interference on the total protein determination assay (turbidimetry method), which should be taken seriously.
