The Ulba river basin is one of the most industrialized regions of Kazakhstan. The development of mining and metallurgical industries has increased pollution of the basin's surface waters by heavy metals, primarily zinc and copper. The taxonomical structure of Trichoptera was studied in reference and impacted reaches of the river basin. A significant decrease in Trichoptera species richness was recorded in the most polluted areas. A total of 35 species were identified at the reference site of the Breksa River, but only 14 in the impacted sites. Ceratopsyche newae, Dicosmoecus palatus, Glossosoma altaicum and Rhyacophila sibirica showed a significant reduction at sites with high heavy metal concentrations.
乌尔巴河流域是哈萨克斯坦工业化程度最高的地区之一。采矿和冶金工业的发展增加了该流域地表水受到重金属（主要是锌和铜）的污染。对该流域参考河段和受影响河段的毛翅目分类结构进行了研究。在污染最严重的地区，毛翅目物种丰富度显著下降。在布雷克萨河的参考站点共鉴定出35个物种，而在受影响站点仅鉴定出14个物种。新氏角石蛾、腭双距石蛾、阿尔泰舌石蛾和西伯利亚石蚕蛾在重金属浓度高的站点数量显著减少。
