STUDY LEVEL heavy and toxic metals in rats with food STRESS
The paper presents the results of a study of the elemental composition of body tissues of laboratory animals against the backdrop of the impact of nutritional factors. The study was performed in male rats of the Wistar. During the accounting period, the animals were divided into three groups depending on the power consumption of the diet. Animals in the control group (K) was obtained within 60 days of a full semi-synthetic diet (basal diet (OR). Pets I experimental group consumed a semisynthetic diet I (CP I), consisting of a mixture of basic food (50%), instant food (PBI) (50%) and water, the animals of group II - semisynthetic diet II (CP II), consisting of a mixture as the main feed and PBP (50%) and carbonated soft drinks. Elemental analysis study of biological substrates and products of animal nutrition carried out by atomic emission and mass spectrometry with inductively coupled argon plasma on the Optima 2000 DV and ELAN 9000 (PerkinElmer, USA). analysis of the mineral composition of the total and semi-synthetic diet used in the experiment, evidence of significant differences in the content of chemical elements. studies have shown that the addition of the main food of fast food products in combination with water or a carbonated beverage has had a negative impact on the growth and development of the experimental animals. Assessment of the elemental composition of body tissues showed significant changes in the elemental status of experimental animals. Showed an increase in the concentration of heavy and toxic elements, probably due to deficiency of essential and macro.
