Scvortsova T.A. CONTENT OF HEAVY METALS IN FRUITS ROSA MAJALIS HERRM., GROWING IN THE PARK ZONES OF THE CITY OF ORENBURGIndustrial enterprises, transport and man-made landscapes of cities have caused an increase in emissions of harmful substances into the environment. Among these substances, heavy metals play a special role, since they can accumulate in the human body under certain conditions, while disturbing the physiological processes in the body. Heavy metal contamination and accumulation is a serious problem around the world due to the toxicity, abundant sources, non-biodegradable properties, and accumulative behavior of heavy metals. In modern conditions, the term heavy metals is most often considered not from the chemical, but from the medical, biological and ecological points of view. It should be noted that fruit plantations growing in parks and squares of cities are often used by people for food or as medicinal raw materials. In this connection, the question arises of the ability to accumulate heavy metals by representatives of plantings of urban recreation areas. One of the representatives of the green plantings of Orenburg is Rosa majalis Herrm., Which is actively used by citizens as medicinal raw materials. It has been experimentally shown that copper, zinc and lead are often present among the metals that pollute the soils of the city of Orenburg. Fruits Rosa majalis Herrm. in the investigated territories of parks and squares in some cases accumulate heavy metals at a level exceeding the maximum permissible concentration. It has been established that the nature of the content of heavy metals in the studied soil and plant samples is directly related to the nature of contamination of individual sections of Orenburg.Key words: ecology, heavy metals, fruits, soil.
