The aim of the research was evaluation of the possibility to use organic acids solutions for production of fertilizers based on mineral wool waste. This substrate thanks to inert character and good air-water relationship is commonly used in greenhouse industry. Increased production of vegetable in soilless culture due to world’s population growth. However mineral wool after full crop cycle is non-biodegradable – dangerous waste. Possibility of extraction nutrients from this kind of substrate could be solution of that important environmental problem. Before analyses mineral wool waste was grinded on 0.40 mm sieve. Then the extraction process was conducted using 2 % m/m and 10 % m/m citric acid, 2 % m/m and 10 % m/m formic acid, 0.2 % m/m and 2 % m/m acetic acid for 3 and 6 hours at temperature 25 C. Solid phase before analyses was mineralized. Iron, phosphorus was analyzed using spectrophotometer methods. Iron analysis is based on formation of a coloured ferric ion complex with 2,2’-bipyridyl. Phosphorus analysis is based on formation of molybdenum blue complex. Calcium and magnesium was examined by complexometric titration with EDTA and using Eriochrome Black T as an indicator, while calcium ions concentration was analyzed using calconcarboxylic acid as an indicator. Content of nutrients after extraction from mineral wool waste allows to conclude that obtained liquid phase can be used as a fertilizer component while solid phase can be used in mixed substrate production.

Results of research carried out on a waste rockwool and ammonium nitrate mixtures to examine the possibility of using them in fertilization of plants were presented. Reactions occurring between compounds were analyzed to determine the possibility of an uncontrolled exothermic decomposition of nitrogen fertilizer additive. Results obtained from the analysis of prepared mixtures in various proportions and separate samples of individual compounds were compared. Ammonium nitrate used in the research was supplied by one of the domestic fertilizers producer and waste rockwool was collected after a completed crop cycle of a tomato plant. Each sample was dried and ground before examination. Analysis was carried out using differential thermal analysis coupled with thermogravimetry and mass spectrometry (DTA-TG-MS). Obtained results indicate a possibility of use of rockwool mixed with ammonium nitrate in agriculture. However, it is important to choose optimal proportions of compounds to ensure the thermal stability of the mixture.

Abstract: Food safety is very important for consumers. Fruits, vegetables and cereals are not only the major source of vitamins, minerals, fibre and energy, but can also be a source of many pollutants posing health hazards. Pesticides found in food are just examples of harmful substances affecting food safety. The objective of this paper was to assess short-term health risks assessment based on the concentration of pesticide residues found in agricultural products collected from national food control systems during the period 2005–2013 at the Official Pesticide Residue Laboratory in Bialystok in frame of RASFF (Rapid Alert System for Food and Feed) system. During nine-year testing, totally 2021 fruits, vegetables and cereals were sampled from the north-eastern and central part of Poland and analyzed by gas and liquid chromatography and spectroscopic technique for the presence of 188 active substances of pesticides. Contaminations were not detected in 65.3 % of samples, 31.9 % samples contained residues below the maximum residue levels (MRLs), while 2.8 % of tested samples exceeded MRLs. Among 81 RASFF notifications noted, the greatest number of irregularities concerned exceeding the values of MRL – 41, in 27 cases it was found that a pesticide was not used in accordance with the registration of plant protection product. The highest estimated values for short-term exposure were obtained for plum for the dimethoate, and in the group of toddlers it was 94.6 % ARfD (Acute Reference Dose), and in the adult group it was 23.3 % ARfD.

Teprosyn Mn manganese seed treatment, manufactured by a British firm Phosyn Chemicals Ltd., which was tested in the experiment, has been available on the Polish market for several years. Applied as a seed treatment it results in more intensive development of root system and improves general plant condition. However, in the available literature lacks information on Teprosyn Mn effect on plant healthiness or pathogenic organisms. The aim of the paper was to compare the effect of Teprosyn Mn fertilizer and Raxil Gel 206 chemical seed treatment on pathogenic fungi species: Fusarium culmorum (W.G. Smith) Sacc., Fusarium poae (Peck) Wollen., Fusarium avenaceum (Fr.) Sacc., Bipolaris sorokiniana (Sacc. in Sorok.) Shoem. and Botrytis cinerea Pers. In laboratory conditions the dynamics of growth and sporulation of the above mentioned fungi were assessed on PDA medium with a supplement of 0.1; 0.5 and 1.0 mm cm of Teprosyn Mn and 0.005; 0.05 and 0.5 mm cm of Raxil Gel 206. In vitro Teprosyn Mn manganese fertilizer reveals weak and diversified effect on linear growth of the studied phytopathogens. In the highest concentration (1.0 mm cm) it reduces the growth of Fusarium avenaceum, Botrytis cinerea and Fusarium poae colonies on the level of 7.3–10.1 %, whereas all its concentrations inhibit the sporulation process in B. cinerea i F. avenaceum from 35.3 % to 66 %. Along with increasing concentration in the medium its stimulating effect on linear growth of Bipolaris sorokiniana raises (5.7–18.3 %) and the spore number increases from 40 to 271.5 %.

: The purpose of this paper was to determine the effect of ash from a sewage sludge incinerating facility on yields and mineral composition of Virginia fanpetals, and on the content of heavy metals in soil. The study was based on a pot experiment in which ash obtained from sewage sludge incineration at the Lyna Wastewater Treatment Plant was used as a substitute of mineral fertilizers. The dominant fertilizing ingredients found in the analyzed ash were phosphorus and calcium. The content of cadmium and lead was lower than the allowable concentrations of these metals in mineral fertilizers. Ash from incinerated sewage sludge did not have any substantial effect on the soil content of the mobile forms of cadmium, copper, lead and chromium. With respect to three metals, namely nickel, zinc and manganese, the medium and high doses of ash raised significantly their concentrations in soil. The rate of ash had no influence on the content of sodium and magnesium in the plants but when the highest dose of ash had been applied, the concentration of calcium in plants rose significantly. Ash modified the content of heavy metals in the plant material only very slightly.

Soils periodically, or permanently, waterlogged and soils exposed to flood waters are heavily imperilled to pollution of inorganic and organic compounds. They are primarily compounds that are brought with the inflowing (highly loaded) floodwater and indigenously produced within the soil profile by anaerobic metabolism of the organic matter. PAHs compounds are adsorbed by the soil from the floodwaters and move in the soil profile posing a threat to groundwater. In addition, when the flood recedes, these compounds may be taken up by the crops. In this study soil pollution with polycyclic aromatic hydrocarbons (PAHs) derived from the decomposition of organic matter and silt and their migration in the arable layer of soil.

In the article the problem of vehicle interior as an important environment of human life hase been discussed. The problem is very important in aspect of indoor air quality. A vehicle interior is a specific environment where levels of volatile toxic organic compounds concentrations are particularly high. In the article the results of statistical analysis of human resistance time in vehicle interior are presented. A method of gaseous mixtures toxicity estimation based on in vitro tests has been proposed in application for vehicle cabin interior and compared to the popular toxicity indicators (relative toxicity coefficients). The results of the method application in brand new passenger vehicles (in parking conditions) are presented. The results was correlated with volatile organic compounds concentration in vehicles interior (method: gas chromatography).
