The growth and death processes of microorganisms result in the release of pathogen-associated molecular patterns (PAMPs). Chronic exposure to PAMPs through the gastrointestinal, respiratory, and dermal routes poses a risk of inflammatory effects. The presence of large numbers of microorganisms in the air, water, and soil provides extremely favorable conditions for the release of PAMPs. This study summarizes the characteristics of endotoxins, peptidoglycan, teichoic acids, lipoproteins, and CpG DNA, which are pivotal substances in PAMPs. The occurrence and health risks of PAMPs in different environmental media, such as air, water, and soil, are introduced. The recognition mechanism of PAMPs and their ability to trigger disease are also discussed. The synergistic enhancement of inflammatory responses induced by combined exposure to PAMPs and environmental pollutants is analyzed. Based on current research of PAMPs in the environmental field, this study highlights the urgent need to accelerate research into standardized detection systems, exposure risk thresholds, and epidemiological studies of PAMPs, given the existing limitations. The aim of these efforts is to advance research progress on PAMPs in environmental science and to provide a reference for a comprehensive understanding and assessment of the health risks posed by PAMPs.
