Abstract：The distribution law and transmision mechanismof Volatile Organic Compounds （VOCs）are systematically expounded in polluted site environments，the key influencing factors such as distribution coefficientsand soil physicochemical properties areanalyzed，the mainstream investigation techniques such as active soil gas sampling and passivesoilgassamplingareintroduced，andtheapplicationlogicandlimitationsofriskscreening，modelprediction，and multi evidenceanalysis methods forsteam intrusion risk assssmentare deeply explored.Basedonthe practical needs of polltedsiteemediation，theoptimizationdirectionofivestigationandevaluationtechnologyisproposed，providing technical reference for precise prevention and control of VOCs in polluted sites.
