The problem of intense water pollution by nitrogen and phosphorus compounds is very significant in the 21st century. The pollution is caused by the widespread application of traditional fertilizers in the cultivation of agricultural crops. Nowadays, the research is carried out and the compositions of fertilizers similar in structure with glassy phosphate materials are developed. Inorganic materials, such as carbon fibers, graphite [1], porous glass, silica gel, are widely used for soil, wastewater and air purifica...

Apatite is mineral - common name for a number of related minerals of the apatite group with the common formula Ca5(PO4)3(F, OH, Cl). Mmineral species in the group are fluorapatite (F - up to 3.8), chlorapatite (Cl - up to 6.8), hydroxylapatite, carbonate-apatite. Kola apatite concentrate is a promising and raw material for complex processing, allowing to produce, in addition to the basic product пїЅ phosphoric fertilizers, strontium, rare earth elements and fluorine compounds. Despite obvious environmental expedie...

THMs in disinfection by products are especially important because of their potential carcinogenity. In this work two different liquid-phase microextraction methods namely US EPA 551 microextraction method and German DIN 38407 standard method were compared for the determination of trihalomethanes (THMs) including chloroform (CHCl3), bromodichloromethane (CHBrCl2), dibromochloromethane (CHBr2Cl) and bromoform (CHBr3) in water samples was developed, with analysis by gas chromatographyelectron capture detection (GC-EC...

Volatile organic compounds (VOCs) have been known as human risk factors in urban environments, as well as primary contributors to the formation of photochemical oxidants.These compounds are a major component of atmospheric pollutants in Konya, that is a large city in Turkey. This study assessed the concentrations of seven volatile organic compounds (VOCs), including Ethylbenzene, m/p xylene, styrene , o- xylene, 1,3,5 Trimethylbenzene, 1,2,4 Trimethylbenzene and 1,2,3 Trimethylbenzene, in Konya/Turkey during the p...

Chlorine disinfection is a generally used process for eradication pathogenic microorganisms from drinking water to prevent water-born diseases. It has been demonstrated that natural organic matter (NOM) in raw water may react with chlorine to form disinfection by-products (DBPs) which are carcinogenic or mutagenic. The occurrence of disinfection by-products (DBPs) in drinking water has been an issue of major concem during the last years due to their adverse health effects. The development and optimization of analy...

Ambient particulate matter contains numerous organic species, including several polycyclic aromatic hydrocarbons (PAHs) that are known or suspected carcinogens. Atmospheric particles were collected using low-volume sampler on glass fiber filters among August 2007-June 2008. The study area is under the influence of heavy traffic. Filter samples were extracted with petroleum ether /n-hexane by ultrasonic agitation, concentrated, and measured at trace levels using gas chromatography–mass spectrometry. The method wa...

This paper presents the estimation of ground vibration parameters induced by blasting excavations realized at eight different sites located close to the residential areas. Within the scope of this study, in order to predict peak particle velocity and determine the slope of the attenuation curve for eight sites, ground vibration components were measured for all blast events over a long period. During the study, while the parameters of scaled distance were recorded carefully, the ground vibration components were mea...
