Impact of environmental quality on the mobility of heavy metals in plants under the conditions of agroforestry systems

Аннотация

The cultivation of tomatoes in two experimental sites under the conditions of unprotected and protected by a forest belt and in two control sites outside the influence of highways has been studied following irrigation with water of different composition. It has been found that the pollution from highways causes not only an increase in the concentrations of heavy metals in leaves, stems, fruits, and seeds of tomatoes, which is well-known, but also induces changes in their structure within the mobility series of elements. This influence has an adverse result during irrigation with the water of different composition. The effect of self-organization of plants by the example of tomatoes in agroforestry systems leads to a significant transfer of heavy metals in the shell of seeds, thereby protecting the seed kernels from excessive pollution with heavy metals.
