Unlike classical monochromatic probes, ratiometric fluorescence probes (RFPs) can self-correct data distortion. In the 75^th year celebration of excited state intramolecular proton transfer (ESIPT) and its new role, ESIPT-RFPs and imaging agents provide dual confirmatory signals. RFPs are characterized by their major sensing mechanisms, including ICT, FRET, ESIPT, and monomer-excimer formation. In recent years, researchers have widely studied ESIPT-RFPs for various environmental and biological analytes, including anions, cations, and neutral analytes. As a result, several reports discuss the ESIPT-RFP for detecting and monitoring a numerous of environmental analytes. The 2-hydroxyphenyl benzothiazole and 3-hydroxy flavones ESIPT cores are most widely utilized for the design. This review examines the diverse mechanisms employed for sensing and signal changes of ESIPT-RFPs for environmental detection and monitoring, focusing on neutral molecules, anions, and cations. The ESIPT-RFP probes have two types of sensing signals: two reversible signals and fixed reference signals, which can be red-shifted or blue-shifted. The ESIPT-RFP sensing mechanisms are categorized into <strong>Types I</strong>, <strong>II</strong>, and <strong>III</strong>.

Determining the routes of exposure—whether through inhalation, skin contact, ingestion, or absorption through mucous membranes—is critical to assess the potential health effects. Accurate exposure assessment is important for identifying health hazards and developing regulations and protective measures. This paper provides a review of, comparison of traditional sampling techniques with newer, non-conventional approaches (sensors application and individual silicone samplers). The essential element of this work is the collection of current literature information on different types of approaches to assess the degree of exposure of occupants of enclosed areas to harmful chemical compounds present in different types of indoor environments – household or work environments. In addition, a summary of current legal regulations concerning monitored parameters, sampling techniques used, and methods applied to estimate health risks was also presented. It was observed that in most cases the level of exposure of users to harmful chemical compounds was estimated based on the determined total levels of a specific group of compounds such as sum of organophosphate flame retardants (FRs), polycyclic aromatic hydrocarbon (PAHs) or polybrominated diphenyl ethers (PBDEs).

This review compiles and critically evaluates recent scientific literature (2020–2025) on the application of atomic spectrometric techniques for elemental determination in bee-related matrices, with a focus on their role in biomonitoring. Among the studies reviewed, bees, pollen, and honey are the most frequently examined samples, each with over 4600 publications in their peak years, while propolis and geopropolis remain less studied, despite their growing importance. The review highlights the increasing use of plasma-based spectrometric techniques, particularly ICP-OES and ICP-MS, because of their high sensitivity, multielement analysis capability, and robustness for trace-level detection. Sample preparation using wet acid digestion remains the most common method, although it is increasingly being complemented or replaced by simpler, more sustainable alternatives, such as ultrasound-assisted extraction and direct dilution. The review also discusses innovative ways to interpret contamination data, including ecological risk indices and bioaccumulation metrics, such as the Overlap Bioaccumulation Index (OBI), which enables comparison of biomonitoring potential across matrices.
