Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that widely present in many industries. Monitoring analyzing PFAS Africa is challenging due to the limited availability mass spectrometry (MS), which an essential technique for detecting PFAS. This review assesses scope impact shortage instruments Africa, emphasizing resulting limitations monitoring environmental public health threats. The analyzes existing monitoring, accessibility MS instruments, technical capabilities within continent. study suggests fewer African countries have sufficient significant underreport data related issues. proposes financial support programs address these difficulties provide necessary instruments. it highly important develop regional centers excellence using investing training gap efforts. So, enhancing crucial successful management environment safeguarding from effects contamination.

The abnormal levels of small molecules, such as iodide ions (I–), in biological systems can be key indicators certain diseases and may pose risks to human health, playing a significant role various physiological processes. Herein, we developed solvothermal method for the synthesis CeO2-based nanozymes (CeO2 NPs, CeO2@Mn CeO2@Se NPs), which serve recognition probes quantitative detection I– urine blood using both colorimetric fluorescence dual methods. NPs showed excellent catalytic activity with aid O-phenylenediamine (OPD) chromogenic substrate; oxidation OPD presence H2O2 produce yellow OPDOX was catalyzed by acting peroxidase enzyme, neutral environment (pH = 6) I–. displayed distinct absorption peaks at 275 nm 450 nm, along maximum emission peak 575 under 380 excitation. Based on these observations, recognition, utilizing detection, developed. limits were found 20 μg/L (3σ/S) mode 0.085 mode. Furthermore, achieved precise blood, offering advantages use resource-limited settings on-site testing. This enhances its potential broader application public health surveillance early disease screening.
