Abstract

Given that with plant products to human body receives up to 80% of chemical pollutants including nitrates and nitrites, the problem of the negative influence of nitrates on human health remains relevant. The content of nitrates in plants depends on many factors: the species and parts of plants, of the timing of planting, terms, storage conditions and the degree of ripening vegetables as well as doses, timing and methods of fertilizer, farming methods of cultivation of vegetable crops, climatic conditions, etc. To prevent the ingress of these substances in the human body is possible, mainly by controlling nitrates in products during the determination of the quality and safety of products. The purpose of the research was to conduct monitoring and analysis of content of nitrates in foods of plant origin supermarkets and food markets in the city of the Dnipro. The amount of nitrates were determined by the express-method of using a portable electronic ekotester "SOEKS" by measuring the electrical conductivity of the medium fruits and vegetables. For more precise results, held 3-time repeat the measurement at one and the same product. For research use from 20 to 35 samples of each type of product: potato late, beetroot, cabbage, carrot and late, onion, tomatoes and cucumbers greenhouse, apples “Golden. " “Nìtrats’” fruits and vegetables of different types are present in the commercial network of the city of the Dnipro. Often exceeding the permissible amount of nitrates found in carrots and onions 68% and 71%, respectively, the smallest such caseswere in the study of the apples “Golden"– 2%. The largest range of quantitative content of nitrates in various lots of vegetables and fruits observed in the study of onion and beet in the 11-13 times the maximum amount of nitrates was minimal. Whereas, in samples of carrot top and the smallest differences between nitrate quite minor – 2.7 times. The high degree of exceeding the maximum allowable level of nitrate observed in some samples of onions – 4 times above normal, while in others the fruits and vegetables index ranged within 1.2 - 1.7 times. Convenient and fast, quantitative method of determining the relative content of nitrates in vegetables and fruits portable electronic ekotester "SOEKS" can be applied to serial (massive) analyses of fresh plant products.
