在分析植物组织时，土壤被植物组织截留的情况常常被忽略。 这导致结果解释的错误。 植物组织样品取自在诺福克，弗吉尼亚州，里弗黑德，纽约州和日内瓦，纽约州的试验田地块中生长的蔬菜。 在收获时，将植物组织用去离子水洗涤，切成小块，烘干（VA）或冷冻干燥（NY），研磨以通过0.0841-cm不锈钢筛并储存在玻璃瓶中。 对每种土壤的表面15 cm进行取样。 通过电感耦合氩等离子体发射光谱法（ICP-ES）和原子吸收光谱法（ETAA）对组织和土壤的亚部分进行了分析。 土壤和植物组织中的钛（Ti）浓度被用作土壤包裹体的量度。 蔬菜样品中Al、Cr和Fe的含量分别有76%、100%和70%是由植物生长过程中的土壤颗粒包裹体所决定的。
Soil entrapment by plant tissue is often ignored when the tissue is analyzed. This leads to errors in interpretation of results. Plant tissue samples were taken from vegetables grown in experimental field plots in Norfolk, VA, Riverhead, NY, and Geneva, NY. At harvest, plant tissues were washed with deionized water, cut into small pieces, oven dried (VA) or freeze dried (NY), ground to pass a 0.0841-cm stainless steel screen and stored in glass bottles. The surface 15 cm of each soil was sampled. Subportions of tissue and soil were analyzed for a number of elements by inductively coupled argon plasma emission spectrometry (ICP-ES) and electrothermal atomic absorption (ETAA). Titanium (Ti) concentrations in the soil and plant tissue were used as a measure of soil inclusion. As much as 76% of the Al, 100% of the Cr, and 70% of the Fe in the vegetable samples could be accounted for by soil particulate inclusion by the plant tissue during its growth.
