磷(P)和其他化学元素已被用来识别考古遗址上的居民点。这项研究讨论了Chispa组的土壤化学元素与蚊虫的关系，这是一个位于玛雅低地一个平民村庄的晚期古典住宅建筑群。该建筑群被广泛挖掘，并对土壤进行了采样。陶瓷碎片密度作为文物密度的替代指标，只与磷和其他化学元素有部分关联。Chispa组的三个幼虫中有一个与最高磷浓度相吻合，而另外两个--包括最广泛的一个--具有中到低的磷水平。包括颜料制备在内的人类活动的光谱解释了化学元素的非传统分布。高磷水平仍然有助于探测助产士，但它们提供了一个不完整的图景，需要综合考古数据进行背景分析。
Phosphorus (P) and other chemical elements have been used to identify residential middens at archaeological sites. This study discusses the relationship of soil chemical elements and middens at Group Chispa, a Late Classic residential complex at a commoner village in the Maya lowlands. The complex was extensively excavated and soil sampled. Ceramic sherd densities, which serve as a proxy for artifact densities, correlate only partially with phosphorus and other chemical elements. One of the three middens in Group Chispa coincides with the highest concentration of P while the two others—including the most extensive one—have medium to low P levels. A spectrum of human activities that include the preparation of pigments explains the nontraditional distribution of chemical elements. High P levels remain useful to detect middens but they provide an incomplete picture and need to be contextualized by comprehensive archaeological data.
