Multispectral television measurements can be used for applied tasks of environmental monitoring, in particular for measuring the parameters of phytoplankton in aqueous media. In this case, the concentration of phytoplankton particles in the water volume is determined, the average particle sizes and the average concentration of chromophores in the near-surface layer. The aim of the work is to improve the multispectral television method to increase the accuracy of measuring the parameters of phytoplankton. An improv...

The paper is dedicated to the development of system of water objects pollution monitoring. An efficient study of the environment situation and giving appropriate solutions related to its improvement require adequate information, obtained from a large number of various parameters measurements. Conducting of analysis more than 3-4 times per day is more economically efficient if automatic systems for environment monitoring are used. Such system of water pollution monitoring proposed by authors consists of: computing ...

Natural compounds and products are increasingly demanded by the pharmaceutical and cosmetics industries as safer and user friendly alternatives to synthetic variants. Young wheat plantlets, known as wheatgrass, are a valuable source of minerals, vitamins and chlorophyll pigments and the biosynthesis of such compounds may be influenced by the cultivation conditions. The present study focuses onto the chemical profile, mineral and chlorophyll content of cultivated wheatgrass using two different types of water (sprin...

Even if EU traditional agriculture is based on a considerable part on livestock enterprises activities, and many products are sustaining the traditional activities, livestock production is the largest source of greenhouse gases, high water usage, driver of deforestation, loss of biodiversity, land use, European Union (EU) is the biggest food importer and the second food exporter, spend around 40% of its budget on Common Agricultural Policy in detriment of other sectors. This paper work aims to emphasize the impact...

In food industry water is used as a raw material, as a solvent for substances with different density when washing products and equipment, as transport water or merely cooling water.Quality monitoring of the hygienic drinking water and the waste water discharged is one of the conditions requested for all producing, processing, storing, keeping, shipping and marketing product supply units. The increase in acquisition, application and development of knowledge, advanced services and techniques in the fields of environ...

The paper presents how to determine the size of the sanitary protection zones and of the hydrogeological protection perimeter related to a water catchments. The water catchment is made of two boreholes for which the lithological profiles and the optimum exploitation parameters are known respectively, the well depth, captured aquifer thickness, hydrostatic level and optimal operating flow. First borehole intercepts a pressurized aquifer and he second borehole intercepts a free level aquifer. Sizing the severe regim...

The purpose of the study was to develop an electrochemical method for detection of lead at low level of contamination in water samples using a carbon glassy electrode modified with the functionalized azulene: (2E)-2-(azulen-1-ylmethylidene) hydrazine carbothioamide (L) as a complexing polymer film. The modified electrodes were prepared in L solutions (1mM) in acetonitrile (CH3CN) containing tetra n-butyl ammonium perchlorate (0.1 M TBAP) as supporting electrolyte. The analyses were performed on Autolab PGSTAT 12 P...

Water jet technology is friendly and belongs to green technology. Water jet technology is divided depending on whether the water is used only water or a mixture of an abrasive and water to clear water jet and abrasive water jet technology. It is possible to divide as the paper material to the steel. This progressive technology is applied in various sectors of industry. During the cutting operations creates the waste in the forms as used abrasive material, polluted water, sludge, used material and other rest materi...
