АННОТАЦИЯГормональные вещества, все еще обсуждаемые с точки зрения их воздействия на здоровье человека, -это эстрадиол-17, прогестерон, тестостерон, зеранол, тренболон и ацетат меленгестрола (MGA), они могут приводить к их избыточному накоплению в мясе и мясопродуктах. В связи с этим, во многих странах мира ужесточены требования по контролю над содержанием гормональных препаратов в продуктах животного происхождения. Стимуляторы роста, в том числе гормональные вещества и антибиотики, легально и незаконно используются для стимулирования роста домашних животных. В нашей стране в Законе РК «О безопасности пищевой продукции» от 21 июля 2007 года № 301-III ЗРК имеется запрет только относительно продуктов специального назначения (продукты детского питания), это свидетельствует о том, что в нашей стране не ведется должный контроль над содержанием гормональных стимуляторов в продуктах животного происхождения и кормах как отечественного, так и импортного производства. Актуальность этой проблемы обусловлена расширением поставок продукции из стран с весьма разнообразным видом разрешенных там препаратов [1].В этой статье профили риска гормональных и антибактериальных стимуляторов роста представлены на основе недавней информации о токсичности и воздействии на человека, а также представлены рекомендации по управлению рисками для предотвращения воздействия на здоровье человека при использовании стимуляторов роста.ABSTRACT Growth promoters including hormonal substances and antibiotics are used legally and illegally in food producing animals for the growth promotion of livestock animals. Hormonal substances still under debate in terms of their human health impacts are estradiol-17β, progesterone, testosterone, zeranol, trenbolone, and melengestrol acetate (MGA), they can lead to their excessive accumulation in meat and meat products. In this regard, in many countries of the world, the requirements for the control of the content of hormonal drugs in animal products are tightened. In our country, the Law of the Republic of Kazakhstan "On food product safety" dated July 21, 2007 No. 301-III ZRK prohibits only special products (baby food), which indicates that in our country there is no proper control over the content hormonal
This paper presents the research data aimed at resolving the problem of soil purification from high-paraffin crude oil using microorganisms.Samples of oilcontaminated soil were taken from the walls of the oil storage pit at the Uzen oilfield. According to the analysis of the oilcontaminated soil samples, the share of oil was 28 %, the share of mechanical impurities – 9.7 %, and the share of water – 60 %.It has been found that according to the API(American Petroleum Institute) indicators, that oil chemical composition may contribute to its rapid decomposition during bioremediation. Paraffin hydrocarbons are also easily decomposed by bacteria. The bacterial preparation «SHER» was used in laboratory experiments.The method of bacteria immobilization with the «SHER» biological product on the medium made from screenings of shell limestone wastes has been chosen.The conditions for conducting experimental laboratory studies on cleaning oil-contaminated soils by biological remediation are described.According to the results of the research, it was established that the immobilization of bacteria of the biological product "Sher" by a carrier in the form of sifting limestone-shell rock showed a high degree of purification of oil-contaminated soil (88.63%).To study the further activity of bacteria, experiments were conducted on the secondary use of thesolution of residual mother waterof the biological product "SHER", used in the process of cleaning oil-contaminated soil.The results of experimental studies using solution of residual mother water and immobilization by screening showed the degree of soil purification (45.7%). Thus, based on the results of studies of the drug "SHER", it can be concluded that this drug can effectively neutralize oil products in the soil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
