【 摘 要 】

The article considers the results of the heavy metals determination in the components of ecosystems of small rivers (water, sediments, macrophytes) of the Amur-Zeya Plain agricultural landscape. In the waters of small rivers, a high level of iron, zinc and copper is due to the natural factor. The lead and cadmium level in the waters of small rivers did not exceed the maximum permissible concentration (MPC). The level of heavy metals in bottom silt of small rivers corresponded to background values. Excessive concentrations of cadmium, manganese, and lead are characteristic of aquatic moss and rooting hydrophytes. The results of studying the level of heavy metals in the components of aquatic ecosystems of the Amur-Zeya Plain are the basis for further study of the technogenic load on small rivers of the agricultural landscape.
