The city ofZaporizhzhyais one of the most technologically developed cities ofUkrainewith significant scientific and technical and production potential. The basis of the city's industry is a metallurgical complex, which has a great influence on the state of atmospheric air. This problem is especially acute in the Zavodskyi district of Zaporizhzhya with a significant concentration of enterprises of ferrous and nonferrous metallurgy, which inevitably emphasizes the urgency of the decision of health care issues of the population living in the area.The article is devoted to the estimation of risk for population health from emissions of the industrial enterprises in the Zavodskyi district of Zaporizhzhya. As part of the stationary source’s emissions of industrial enterprises, there are various chemical compounds, of which the most common are dust, sulfur compounds, nitrogen oxides, carbon monoxide, phenol, sulfuretted hydrogen, and others. Getting them into the human body leads to deterioration of health, damage to organs and systems, the emergence of chronic diseases.The values of the risk factors for inhalation exposure exceed the permissible level for sulfuretted hydrogen, phenol, formaldehyde, carbon bisulfide, nitrogen dioxide, sulfur dio-xide, suspended solids, ammonia in the Zavodsky district. They are at medium and high le-vels, indicating that there is a risk of adverse effects in most of the population.It was established as a result of research, that in the majority of the population of the Zavodskyi district of Zaporizhzhya there is possibility to get respiratory organs diseases, organs of vision diseases, circulatory, cardiovascular and central nervous systems diseases, congenital defects of development at acute inhalation effects., Город Запорожье – один из наиболее технологически развитых городов Украины со значительным научно-техническим и производственным потенциалом. Основу промышленности города составляет металлургический комплекс, который во многом влияет на состояние атмосферного воздуха. Особенную актуальность эта проблема приобретает в Заводском районе г. Запорожья со значительной концентрацией предприятий черной и цветной металлургии, что непременно подчеркивает актуальность решения вопросов охраны здоровья населения, проживающего в данном районе.В работе рассматривается оценка риска для здоровья населения от влияния выбросов промышленных предприятий Заводского района г. Запорожья.В составе выбросов стационарных источников промышленных предприятий присутствуют разнообразные химические соединения, из которых наиболее распространенными являются пыль, соединения серы, оксиды азота, оксид углерода, фенол, сероводород и другие. Попадание их в организм человека приводит к ухудшению здоровья, поражению органов и систем, возникновению хронических заболеваний.В Заводском районе значения коэффициентов опасности при ингаляционном влиянии превышают допустимый уровень для сероводорода, фенола, формальдегида, сероуглерода, азота диоксида, ангидрида серного, взвешенных веществ, аммиака и находятся на среднем и высоком уровнях, что свидетельствует о наличии риска развития неблагоприятных эффектов в большей части населения.В результате исследования было установлено, что у большей части населения Заводского района г. Запорожья при остром ингаляционном влиянии существует вероятность формирования заболеваний органов дыхания, кровеносной системы, органов зрения, сердечно-сосудистой системы, центральной нервной системы, врожденных дефектов развития., Місто Запоріжжя є одним з найбільш технологічно розвинених міст України із значним науково-технічним і виробничим потенціалом.

A new combinatorial method for the preparation of substituted thiazolo[4,5-b]pyridines, which utilizes cyanoacetamide, heterocumulenes (isothiocyanates, carbon bisulfide), and ethyl-4-chloroacetoacetate in a new SN2→Thorpe–Ziegler→Thorpe–Guareschi domino reactions has been developed. The obtained thiazolo[4,5-b]pyridines were then used together with aldehydes and malononitrile in another Knoevenagel reaction→Michael reaction→hetero-Thorpe–Ziegler domino reaction for the synthesis of substituted 4,6-dihydro-5H-pyrano[2,3-d]thiazolo[4,5-b]pyridines.

Earlier reported schemes of main way of absorbent degradation were corrected un the course of joint studies by NMR and chromatography-mass spectrometry of a composition of aqueous solutions of monoethanolamines used in absorption removing acidic impurities H2S, CO2, SO2, COS, CS2 from exhaust gas and in view of new literature data.

Three types of [60]fullerene crystals were obtained. The first one was the direct commercial [60]fullerene, and the other two were recrystallized from the first one in carbon bisulfide and in carbon bisulfide/petroleum ether, respectively. Scanning electron microscopy (SEM), X-ray powder diffractometry (XRD), and FT-IR spectrometry were used to study the physical characteristics of the crystals. The thermal stability of the three [60]fullerene crystals was studied by differential thermal analysis (DTA), and the effects of the three [60]fullerenes on the mechanical sensitivity and friction sensitivity of HMX were tested and analyzed. It was found that the three types of [60]fullerenes have different thermal stabilities, and the friction and impact sensitivities of HMX are reduced from 100% to 70% and to 60%, respectively when 1% [60]fullerene 3 was added in HMX.

The results are presented of experimental and theoretical studies of the action of nano-and micro-second electron beams on an atmospheric-pressure nitrogen-oxygen mixture with a CS2 impurity. It is demon-strated that there are two modes of impurity conversion that depend on the beam parameters and differ in both the mechanism involved and the final products. The effect of the external electric field on the impurity conversion is studied experimentally. A computer model of the processes is developed, and an analysis of the experimentally observed effects is performed.

Carbon nanorods are prepared at large scale from CS2 and metallic Li (autoclave, 600 °C, 10 h, yield given in g) and characterized by powder XRD, SEM, TEM, and N2 physisorption.

Emission rates of dimethyl sulficle (DMS), carbonyl sulfide (COS), and carbon disulfide (CS2) to the atmosphere from paddy fields at Ryugasaki, Ibaraki Prefecture, Japan were measured by using the closed chamber method. DMS was emitted mainly through the rice plant and its emission rate was much higher than those of COS and CS2. During a cropping period COS was slightly absorbed by the rice plant. Significant diurnal and seasonal variations of DMS iuxes were observed. The highest DMS iux was observed immediately after the heading day of rice plant. The annual DMS emission rate was in the order of mineral plot > straw plot > no-N plot, ranging from 4.5 to 6.9 mg S m-2 yr-1. The annual COS emission rate was in the order of straw plot > no-N plot > mineral plot, ranging from -0.2 to 1.8 mg S m-2 yr-1. The annual CS2 emission rate was slightly higher in the straw plot, ranging from 0.9 to 2.0 mg S m-2 yr-1.

Experiments on fs laser-induced transient grating (LITG) in carbon bisulfide (CS2) are carried out to explore the chirp characteristics of a white-light supercontinuum (SC) generated by a 800-nm, 160-fs laser pulse in a 4-mm thick Al2O3 crystal. Two orders of diffraction signals of SC by fs LITG in CS2 are observed, demonstrating that both the third-order process and the fifth-order process are present simultaneously. The experimental results also imply that the formation of an fs transient refractive-index grating in CS2 is mainly due to the electronic polarization process.

Crop protection entomology became the name for ESA Section F in 1964. It was preceded in 1961 by Chemical Control and in 1953 by Chemical Control Investigations when Section F was first recognized in the organizational structure of the society. Nevertheless, it was the substance of Section F that begat the Association of Official Economic Entomologists in 1889, the original constitution for which limited membership to economic entomologists. This fledgling society was born into the era of kerosene-soap emulsions, Paris green, carbon bisulfide, and hydrogen cyanide.

Experimental conditions for accurate measurement of long spin—spin relaxation times by the CPMG—SEFT method are described. The expected 13C value, T2 = T1≅44 s for carbon disulfide, is reported for the first time and experimental diffusion behavior agrees with classical theory.

Up to 6 W of cw laser power has been extracted from vibrationally excited CO produced in free‐burning CS2/O2/N2O flames burned at pressures of 10–40 Torr. A peak efficiency of approximately one laser photon for every eight fuel molecules has been obtained.

The coexistence curves L1 [Formula: see text] L2 of the following systems have been investigated: (1) aniline–hexane; (2) methanol–cyclohexane; (3) methanol – carbon bisulfide; (4) acetic anhydride – cyclohexane; (5) acetic anhydride – carbon bisulfide; (6) triethylamine–water. Instead of using the usual method of Alexejew, which has disadvantages stated in the text, we have preferred the direct analysis of equilibrium phases at constant temperature.

1. The activity of CS 2 35 retained on the walls of the measuring equipment filled with active vapors of carbon bisulfide was determined directly. 2. The capture of the compound by the walls is determined to a great extent by reversible sorption, so that in normal measurements of the residual background the information on this sorption is lost. 3. The sorption effects are very large and differ for various materials. Values were obtained for the relative pollution by CS 2 35 vapors of various materials used in measuring installations with internally-filled counters. 4. A relationship was obtained between the pollution of various materials and the density of the active carbon bisulfide vapors in a chamber.

The infrared absorption spectrum of H2O, HDO and D2O in dilute solution in carbon tetrachloride and carbon bisulfide has been investigated with a grating of high resolving power, in the region 2.6–3.8μ. Several bands have been identified as v3 bands and the hitherto unobserved v1 band for H2O is believed to have been found. The frequencies observed are compared with the same frequencies in the vapor and a displacement of frequency which is proportional to the frequency itself is observed in solution. A fine structure is observed in the case of H2O which may be ascribed to rotation unless some other explanation is found. The spectrum in carbon bisulfide appears to be identical with that in carbon tetrachloride.

Fumigants that are liquid formulations at room temperature have been widely used to kill insects in stored products, containers, and soil. Carbon bisulfide was one of the first fumigants used on a large scale as early as 1869 and is still the main fumigant used in some parts of the world (Bond 1984). Carbon bisulfide is highly flammable (Fleming and Baker 1935) and is usually formulated with carbon tetrachloride to aid distribution of fumigants in grain masses (Berck 1958) and to reduce the fire hazard. Although carbon tetrachloride is of low toxicity to insects it causes extensive liver damage in humans (Rouiller 1964). Liquid fumigants were widely used to disinfest stored grain in the USA until recently (White et al. 1985), and are still used in many other parts of the world (FA0 1985).

In the manufacture of glassware it is important to distinguish between surface-markings and cords, both of which are serious defects and detrimental to quality. To do this immerse the piece of glass under test in a liquid of the same refringence and sight through liquid and glass toward a distant light. Under these conditions surface-markings disappear altogether. Cords, on the other hand, stand out more distinctly than before. The relative refringence of a cord compared with that of the adjacent glass can also be determined at the same time. For ordinary crown glasses monochlorbenzene is suggested as an immersion liquid. To lower its refractive index add benzene; to raise it add carbon bisulfide or monochlornaphthalene.

The thermal decomposition of bromomagnesium N-aryl- or N-alkyl-N-bromomagnesio-dithiocarbamate (3), prepared in situ from amines, carbon disulfide, and a Grignard reagent, is a new and convenient method for the preparation of aryl or alkyl isothiocyanate.

A method of volatilizing carbon bisulfide with steam was successfully employed in soil fumigation tests for the control of the greenhouse centipede ( Scutigerella immaculata Newp.) infesting ground beds in a commercial greenhouse at Indianapolis, Indiana. The carbon bisulfide was placed in a steel drum and steam under 50 pounds pressure allowed to pass through, volatilizing the material and forcing the gases into underground tiles, extending the length of the bed at a depth of about 16 inches. A high mortality of centipedes and other soil-infesting forms was secured.
