对局部区域内连续鞋印和连续鞋印之间采集的土壤样本进行花粉分析，并相互比较以及与印有鞋印的鞋子的土壤样本进行比较。目的是确定使用此类样本的法医价值，以确定人与犯罪现场之间是否存在关联。这是通过确定同一局部区域内土壤中的鞋印中的花粉组合的不同程度，以及鞋子上的土壤中的花粉组合与这些鞋子所形成的土壤中的鞋印中的花粉组合的不同程度来完成的。来自鞋印和鞋印之间的样本显示出高度的相似性，这表明来自局部区域内的此类样本的花粉组合是同质的。采样深度从 1 毫米变化到 20 毫米并没有显着改变样品的花粉含量。鞋子上的两个土壤样本的花粉含量彼此之间以及鞋印之间的土壤样本之间的花粉含量非常相似，这表明鞋子上土壤中的花粉组合与这些鞋子所形成的土壤中鞋印中的花粉组合没有显着差异。
Soil samples taken from and between consecutive shoeprints within a localized area were analyzed for pollen and compared with each other and with soil samples from the shoes that made the prints. The purpose was to establish the forensic value of using such samples to determine whether or not there is an association between people and crime scenes. This was done by determining the degree to which pollen assemblages in shoeprints in soil from within the same localized area differ, and the degree to which pollen assemblages in soil on shoes differ from assemblages in shoeprints in soil made by those shoes. The samples from and between the shoeprints showed a high degree of similarity, suggesting that pollen assemblages of such samples from within a localized area are homogeneous. A change in sampling depth from 1 mm to 20 mm did not significantly alter the pollen content of samples. The pollen content of the two soil samples from the shoes showed a close similarity to each other and to the soil samples from and between the shoeprints, indicating that pollen assemblages from soil on shoes do not differ significantly from assemblages in shoeprints in soil made by those shoes.
