摘要
火场燃烧残留物物证的识别和检验鉴定对认定火灾性质有重要作用,其中土壤类物证是火场中一种重要的检材类型,土壤作为典型的渗透性介质,渗入其中的助燃剂虽不易发生燃烧,但火场环境复杂,土壤中助燃剂残留物物证检验鉴定不可避免地受到风化、微生物效应等因素干扰。为了解土壤中助燃剂残留物物证鉴定领域的研究进展,对近年来的相关研究进行了梳理,主要包括土壤中助燃剂残留物物证火场提取位置及鉴定,干扰因素如微生物效应、风化效应以及2者耦合对助燃剂物证的影响,微生物效应的抑制等研究,并对今后的研究方向进行了展望,旨在为土壤中助燃剂残留物物证鉴定提供参考。
The inspection and identification of fire debris plays an vital role in determining the nature of fire.Soil,as one of the most common physical evidences in fire,is likely to be seri-ously influenced by the many factors in the complex fire scene,such as high temperature,weath-ering and microbial degradation,even though soil physical evidence is hardly subjected to flame.To keep abreast of the latest research progress and provide a reference for the identification of ac-celerant residue physical evidence in soil,this paper has sorted out the current researches on physical evidence collection in fire scene,pretreatment in identification laboratory,interference factors of microbial degradation,weathering,and the coupling of them,and the prospect of re-search interests was outlooked at last.
