The use of soil microarthropods as indicators of soil pollution in home gardens of an industrial area has been covered in this study. Soil samples were collected from 25 home gardens in three zones in Eloor during summer and North East monsoon from 2014 to 2018, for the study of soil microarthropods, soil properties, soil nutrients, and trace elements. The relationships among QBS-ar, microarthropod abundance, soil properties, and soil nutrients, were used to estimate the pollution hazard of the industrial area. The microarthropods present in the study area were Coleoptera, Hymenoptera, Diplopoda, and Araneae. A prominent study area feature was the absence of Collembola and Acari. The QBS-ar index score in these regions showed that the home gardens located adjacent to the industrial area showed low soil quality, with soil quality class values ranging from 1 to 2 throughout the study period. Discriminant analysis of soil nutrients with soil properties and microarthropod abundance showed that in Zone 1 and Zone 2, the data in 2018 was very well discriminated compared to other years. The hazard assessment in the Eloor region showed various levels of hazard zonation: Zone 1 with high-hazard and medium-hazard areas, Zone 2 with medium-hazard areas, and Zone 3 with low- and medium-hazard areas. The study is one of the first kinds that have used QBS-ar scores and soil properties along with soil nutrients and trace elements for estimating the level of hazard in home garden agroecosystems and thus points to an easy, simple, and practical approach in the monitoring and management of soil ecosystems.
本研究探讨了利用土壤微节肢动物作为工业区家庭菜园土壤污染指示物的方法。2014 年至 2018 年夏季和东北季风期间，从埃洛尔（Eloor）三个区域的 25 个家庭菜园中采集土壤样本，用于研究土壤微节肢动物、土壤特性、土壤养分和微量元素。使用 QBS-ar、微节肢动物丰度、土壤特性和土壤养分之间的关系来评估工业区的污染危害。研究区域中存在的微节肢动物有鞘翅目、膜翅目、倍足纲和蛛形纲。一个突出的研究区域特征是缺少弹尾目和蜱螨目。这些地区的 QBS-ar 指数得分表明，与工业区相邻的家庭菜园土壤质量较低，整个研究期间土壤质量等级值在 1 到 2 之间。土壤养分与土壤特性和微节肢动物丰度的判别分析表明，在第 1 区和第 2 区，2018 年的数据与其他年份相比有很好的区分。埃洛尔地区的危害评估显示了不同程度的危害分区：第 1 区为高危害和中危害区，第 2 区为中危害区，第 3 区为低危害和中危害区。本研究是首次使用 QBS-ar 评分以及土壤养分和微量元素来评估家庭菜园农业生态系统危害水平的研究之一，为土壤生态系统的监测和管理提供了一种简单实用的方法。
