Study of patterns of accumulation of the most dangerous ecotoxicants in wild medicinal plant raw materials of various ecotopes of the Voronezh region

Voronezh region is one of the most important areas of agriculture and crop production. The purpose of the study was to study the patterns of accumulation of the most dangerous heavy metals in wild medicinal plant raw materials of various ecotopes of the Voronezh region. The accumulation of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic was studied, using an example of 10 types of medicinal plant raw materials, which were produced in 51 ecotopes of the Voronezh region.

Определение содержания свинца в почвах г. Саратова методом рентгенофлуоресцентного анализа

Определено содержание свинца в поверхностных горизонтах вдоль пяти автомобильных трасс четырех районов г. Саратова (Октябрьский, Заводской, Ленинский, Кировский) методом рентгенофлуоресцентного анализа. Для калибровки рентгенофлуоресцентного анализатора на свинец был использован метод добавок.

ЭКСТРАКЦИОННОЕ «CLOUD POINT» КОНЦЕНТРИРОВАНИЕ СОЕДИНЕНИЙ СВИНЦА МИЦЕЛЛЯРНЫМИ ФАЗАМИ ПАВ

Рассмотрен аналитический метод – «экстракция в точке помут-
нения» применительно к концентрированию и выделению соеди-
нений свинца из различных матриц. Дана характеристика при-
меняемых для этих целей ПАВ. Оценены факторы, влияющие
на коэффициент, константу распределения и коэффициент кон-
центрирования хелатов в мицеллярные фазы ПАВ. Дана срав-
нительная характеристика лигандов-комплексообразоват елей,
применяемых для мицеллярной концентрации ионов свинца.

Accumulation of Heavy Metals and Arsenic by Medicinal Plant Raw Material of Bitter Hollow

The Voronezh region is traditionally the most important area of crop production and farming. The purpose of the study was to study the contamination by heavy metals of medicinal vegetable raw materials of the Voronezh region using the example of grass of the bitter emery collected in urban and agro-ecological systems, which experience various anthropogenic effects. The accumulations of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic were studied, in 51 samples of pooch grass bitter.

Accumulation of heavy metals and arsenic with medicinal herbal raw material of common shovel harvested in Voronezh region

The Voronezh region is traditionally the most important area of crop production and agriculture. The purpose of the research was to study the contamination with heavy metals of medicinal plant raw materials of the Voronezh region using the example of the roots of ordinary burdock, prepared in urbo- and agro-ecosystems, which have various anthropogenic effects on themselves. The accumulation of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic in 51 samples of raw materials was studied.
