Abstract
The samples of drinking water in bottles were compared by organoleptics, chemical composition and safety. To determine safety the method of biotesting with Planaria Dugesia tigrina was used. The degree of Planaria regeneration in different water samples was measured. The data obtained showed that this test object may be successfully used for assessment of safety of drinking bottled water with sufficient correlation with organoleptic properties and toxic elements content. The properties of water were shown to depend on the source and producer. DOI: 10.5901/mjss.2015.v6n2s4p29

In 21st centure the level of hazard caused by anthropogenic influences achieved its maximum, and ecological prognosis shows further acceleration of such influence
Special attention has to be paid for foodstuffs because they are in the end of ecological chains: xenobiotics – soil – air – plants – animals –foodstuffs – human being
Special computer programmes allow to count and analyze the effect of environmental factors on the dynamics of regeneration. [2, 6, 7] In this study we investigate the possiblity of using biotesting with Planaria for express assessment of safety and quality of drinking water in bottles
Summary
In 21st centure the level of hazard caused by anthropogenic influences achieved its maximum, and ecological prognosis shows further acceleration of such influence. Special attention has to be paid for foodstuffs because they are in the end of ecological chains: xenobiotics – soil – air – plants – animals –foodstuffs – human being. I. Vernadsky even in 1926 proposed a term “biosphere” for a unique system of humans, animals, plants, microorganisms and their environment. In biosphere there are more than 60,000 different xenobiotics invasing into natural circulation of substances. These xenobiotics enter the human organism mainly from foodstuff (70%), air (20%) and water (10%). That’s why it is so important to improve new appropriate methods for assessment safety of foodstuffs and water on all the steps of technological chain: producing, storage, transportation, purchasing, with aim to provide the commonwealth with foodstuffs of high quality
