The use of bryophytes as an indicator of environmental quality has been addressed on numerous occasions and in different places of the world under a variety of conditions. However, in Latin America their use is still limited. In the study described here, the presence and distribution of the bioaccumulation of lead in bryophytes has been evaluated in both contaminated and uncontaminated sites in Villavicencio (Colombia) and its surroundings. Villavicencio is a medium-sized city that is similar in size to many other cities in Latin America. A total of 52 samples of bryophytes were collected, of which 43 belong to points distributed in urban areas of the city (residential, commercial, highway), and the remaining nine are from uncontaminated areas (reference) taken in the surroundings of the city. The samples were treated with acid (nitric and hydrochloric) and subsequently measured by atomic absorption spectrometry. It was found that Pb concentrations in the commercial sector are between 1 and 6 times higher than in the residential and highway sectors. Spatial distribution maps of lead over the sampled territory were created using Arc-GIS 10.1. It is noteworthy that the values obtained are higher than those found in European cities.

使用苔藓植物作为环境质量的指标已在许多情况下以及在世界各地的各种条件下得到解决。但是，在拉丁美洲，它们的使用仍然受到限制。在此处描述的研究中，苔藓植物中铅的生物富集的存在和分布已在比亚维森西奥（哥伦比亚）及其周围地区的受污染和未受污染地点进行了评估。比亚维森西奥（Villavicencio）是一个中等城市，其规模与拉丁美洲的许多其他城市相似。总共收集了52个苔藓植物样本，其中43个属于分布在城市市区（住宅，商业，高速公路）的点，其余9个来自城市周围未受污染的区域（参考）。样品用酸（硝酸和盐酸）处理，然后通过原子吸收光谱法测量。人们发现，商业部门的铅浓度比住宅和公路部门的铅高1至6倍。使用Arc-GIS 10.1创建了采样区域内铅的空间分布图。值得注意的是，所获得的价值高于欧洲城市中的价值。
