Никель в водах притоков Телецкого озера по результатам многолетних исследований

The Cheap SeatsA Note from the Editor Willie Steele Just a few weeks into 2020, my family and I left for what was supposed to be an entire semester in Europe. I’d be teaching in Vienna, Austria and planned to travel most weekends to various places I’d only read about. When we left, there were mentions of a virus that had been gaining momentum around the world, but my concerns were more about how much Wienerschnitzel I could eat and how I would do without having baseball for that long. For the first time in several years, I wouldn’t be attending the NINE Spring Training Conference and would miss the annual Cactus League games that signal the start of a new season. Just a few weeks into our experience abroad, there were rumblings about travel being limited if the virus numbers kept climbing. But I wasn’t too worried because I’d already discovered the answers to my first concerns: 1) I can eat a lot of Wienerschnitzel when given the chance, and 2) a guy in Prague tipped me off to some baseball leagues there that start in April. I’d already started making plans to Czech them out before coming home. Unfortunately for us, the coronavirus number kept climbing and our group was brought home six weeks earlier than planned. I’d missed the NINE conference by a week, but I was thankful my friends had gotten to enjoy the last baseball for several weeks before things shut down. Little did we know how long it would be before baseball would start again as teams at every level had shut things down for the spring. With little to do during the 14-day quarantine upon our return, I spent a lot of time online, quickly realizing I wasn’t the only person struggling with missing baseball. I felt more than a little guilty for this as the virus had already had deadly effects on people around the world, disrupted the education system, and brought many businesses to a grinding halt. But it was springtime, and I was supposed to be enjoying the start to another baseball season. I saw people posting videos of old ballgames and debating others about who the best team was (or who the best left-handed hitter was with two men on in the bottom of the 8th inning while playing a night game with a temperature of 72 degrees or [End Page xi] warmer). Others were even showing off artwork they’d begun creating from old baseball cards (I admit that I got so bored I began doing this as well). The idea for this issue of the journal came from seeing how others online dealt with no baseball. We put out the call for articles, calling the issue “Baseball Is . . .” because for each of us, baseball is something different. The response was nothing less than overwhelming. We had enough submissions to fill nearly six regular issues of NINE. The articles ranged from childhood memories of favorite teams and players to introspective narratives about the relevance of a game in the midst of a global pandemic. The writers ranged from an octogenarian who vividly recalled games more than six decades past to a teenager who spends his time on Waveland Avenue waiting for home run balls to land in the street. Pieces were submitted by well-known writers whose work has appeared in national publications and first-time authors who simply wanted to share their stories. And while I would have loved to include many more articles than what this double issue you are reading can hold, the reality was that some difficult decisions had to be made. I felt like the guy who gets to pick his starting line-up from a list of All-Stars. No matter how good the list I selected would end up being, some fine talent was going to be left off the roster. The result, however, is what I hope is an eclectic selection of work from a variety of perspectives. There is a little poetry, a creative piece or two, reflections on family, cultural commentaries, tributes to families and friends, and...

Chicago, Sept. 25, 1895. To the Editor: —For the first time in several years, if not in its history, this library has been united and roughly sorted into periodicals, transactions, monographs and pamphlets. There are about two hundred and fifty incomplete sets of periodicals, mostly United States, with some English, French and a few German, Italian and Spanish. Some of these, mostly the older United States periodicals, have been bound in a cheap but durable style, but the greater majority are unbound. This number includes some not now received in exchange, but this deficiency is made up by new periodicals, so the number remains about the same. By the terms of the contract, the library does not receive all periodicals and books sent to theJournal. Some of these are kept for office copies and some become the property of the reviewers. The value of these sets is their incompleteness,

North Korea underwent a seemingly seamless leadership transition from father to son in the midst of a struggling economy and widespread hunger. The North drew even closer to China but also reached out to the United States and Russia for the first time in several years. Meanwhile, inter-Korean relations remained in a deep freeze.

A new concept for the quality control of natural waters was proposed. Currently, for this purpose a free method is used which involves the comparison of measured concentrations of each pollutant with the established standards, such as maximum permissible concentration ( MPC ), without specifying the probability of the fulfillment of C ≤ MPC or C > MPC type conditions. This control scheme corresponds to the concept of absolute precision of the analysis results and control. Following the modern theory of security it is necessary to get to the concept of acceptable risk, according to which the value of MPC must be supplemented by indicating the probability of finding the controlled parameter within the tolerance or the risk of going beyond its limits. In the mathematical formulation this is the task of constructing a confidence interval on the probability of performing a specified condition (tolerance interval). The current work explored different methods, applied to the problem of quality control of waters, by constructing parametric and nonparametric tolerance intervals, the first of which is independent of the law of distribution of a controlled parameter, while the second can be built under the normal law. We investigated the question of the amount of necessary measurements that should be performed to assess the water quality using each of these methods, and concluded that the parametric approach has substantial advantages. The paper also developed a method for separate confirmation of the requirements established for the mean concentration of the controlled parameter and its variance. It was shown that the required volume of test method occupies an intermediate position between the methods of parametric and nonparametric tolerance interval. To overcome the limitations in terms of normality of the relevant distribution law, a procedure was developed for estimating the required probabilities based on the mathematical apparatus of the order statistics that combines the advantages of both approaches. All of these studies were illustrated by computational examples that represent, in essence, the work practices of the practical application of the proposed approaches.

We have examined influence exerted by eight microbiological and chemical environmental factors on mortality, primary incidence and disease prevalence per 19 disease classes in 45 municipalities in Tatarstan, including children, working age population and elderly people, over 2019–2023. The study aimed to identify priority environmental risk factors causing medical-demographic losses of the population per specific classes of diseases and nosologies in Tatarstan. The study tasks included establishing correlations between environmental and medical-demographic factors as well as their strength; building predictive regression models; assessing regression coefficients of additional mortality and morbidity risks. The results obtained by comparative analysis of influence exerted by ambient air, water and soil quality in Tatarstan confirmed the existing national trends in Russia as regards associations between mortality and morbidity and chemical pollution in ambient air, water supply deviating from the existing sanitary-epidemiological rules and standards, soils not conforming to safe standards per microbiological indicators; in addition, we established some health risks specific for Tatarstan. The greatest number of strong correlations was established for ambient air quality; a smaller number of medium correlations was established for water quality; the smallest number of correlations was established for soil quality. Children remain the most susceptible population group as regards primary incidence and disease prevalence. Multifactorial models established that additional risk of environment-associated incidence ranged between 44 and 67 % for children, equaled 57 % for working age population and 30 % for people older than working age per the existing mean morbidity rates per various classes of diseases. A strong direct correlation was established between incidence of neoplasms in children and the proportion of ambient air samples containing NO2 and NH3 in levels beyond the maximum permissible concentration; the same correlation was established between NH3 levels exceeding the maximum permissible concentration and prevalence/incidence of complications of pregnancy and childbirth among working-age women. Regarding mortality, we revealed correlations of varying strength; a strong non-linear correlation was found between all-cause mortality among people older than 80 years and the proportion of air samples containing NO2 in levels beyond its maximum permissible concentration. Predictive models allow us to calculate a positive effect of modifying environmental factors for reducing additional risk of population morbidity and mortality.

The composition and speciation of trace elements (Cu, Pb, Zn, Cd, Ni, Co, Mn, Fe, Ba, and Sr) in surface water and bottom sediments of the Pirogov water reservoir have been studied. It was found that the metal content in surface water does not exceed the maximum permissible concentration (MPC) for fishery water reservoir excluded Zn (2–9 MPC) and Cu (up to 2 MPC). According to results of thermodynamic calculations, the predominant metal speciation in water is the free ion (Sr, Ba, Zn, Ni, Co, Cd), fulvate (Cu) and carbonate (Pb) complex. The interstitial water is characterized by an increase in the content of sulfate complex of trace elements in loams, the solid phase of which is also characterized by slightly anomalous contents of Zn, Cd, Co, and Ni. According to data of sequential selective procedure, metals are predominantly immobilized in solid phase of bottom sediments in the crystal structure of silicates or bounded to iron and manganese oxides. Only for Cd and Mn exchangeable and bound to carbonates fractions are characterized by considerable relative contents.

Environmental Quality Objectives for 10 Polycyclic Aromatic Hydrocarbons (PAHs)

Monitoring of surface waters within the transboundary section of the Western Bug River showed, that during 2014–2018, a significant excess of the maximum permissible concentration (MPC) was observed for some substances for fish ponds. As a result of this, the water in the river for these substances was rated as “dirty” in terms of purity and correspond-ed to water quality class IV, namely: phosphorus was observed to exceed the MPC at the observation point Ambukіv vil-lage in 2015 (9.7 times), for manganese – an excess of the MPC at the observation point Ambukіv village in 2018 (9.7 times) and in point Zabuzhzhia village in 2014 (7.9 times), 2015 (8.0 times), 2017 (7.1 times), 2018 (8.3 times); for the total iron – the exceeding of MPC at the observation point Ambukіv village in 2016 (5.95 times) and 2017 (6.13 times); at the observation point Ustilug town in 2016 (5.23 times); in the observation point Zabuzhzhia village in 2016 (9.44 times) and 2017 (5.27 times). The assessment of the surface waters based on the determination of the pollution factor showed that during the study period their quality did not deteriorate but did not meet the norms. In general, surface waters of the river correspond to the second class of quality and are characterized as “poorly polluted” waters by the level of pollution.

Area Monitoring. The average air contamination levels for the Laboratory, perimeter, and remote areas were 0.4, 1.6, and 1.4%, respectively, of the maximum permissible concentration (MPC). Analysis of the higher levels observed during the first part of the year indicated that they were due to radioactive fall-out. The probable average concentration of mixed fission products in the Clinch River were 3 1 x 10/sup -7/ and 4.9 x 10/sup -8/ mu c/cc at Mile 20.8 (point of entry of wastes) and Mile 4.5 (Kingston, Tenn.), respectively; these values are 25.4 and 22.3% of the weighted average MPC. The river MPC, however, was exceeded three weeks during the year, the first two instances resulting from heavy rains which scoured the White Oak Creek drainage basin and the third instance resulting from dilution loss in the river due to a below-normal river flow. Silt monitoring showed that the gamma count rate in the river increased sharply immediately downstream from the point of entry of the wastes, peaking at Mile 16.3. Other local rises of water activity levels are discussed. The average radiation background in the Laboratory and perimeter areas was O.13 and 0.02 mr/hr, respectively. Personnel Monitoring. No personnel exposures exceeded NBS handbook limits. The highest total personnel dose was approximately 9 rem, or 75% of the MP annual dose of 12 rem, and only one individual had accumulated a total dose exceeding the age proration formulas, mostly due to a 1957 accident. Three major contamination events occurred in Oct. and Nov. 1959 and involved equipment failure. The first event resulted in a release of Ru/sup 106/ through process waste lines to the waste treatment plant via a heat exchanger leak, and special control measures were taken to prevent exceeding the MPC in the Clinch River due to the event. The second event resulted in distribution of Ru/sup 106/ particulates over a large protion of the Laboratory area due to short test operations of a fan at the base of an off-gas stack. The third event resulted in plutonium contamination of several buildings from an explosion in a chemical processing plant. No personnel exposures above MP levels resulted from these three events. Minor contamination events are also discussed. (D.L.C.)

The purpose of the work is to apply existing methodological approaches to assessing the negative impact of drainage water on a water body, to establish the dynamics of concentrations of substances in the area from the place of discharge of wastewater/ drainage water to the control gate. The object of the study was a collector diverting drainage runoff into the Don River. The problem under study is especially relevant in connection with the ongoing measures to prevent degradation of a water body in accordance with the decree of the Government of the Russian Federation dated 07.21.2021 № 2012-r. The concentrations of substances in the most polluted jet in the area from the place of discharge of wastewater/drainage water to the control gate (l = 500 m) were calculated using the example of a collector diverting drainage runoff into the Don River. It is shown that if the concentration of a substance in the background is equal to or below the maximum permissible concentration, then when drainage water are discharged with excess of the standard concentrations of substances and their subsequent dilution by the flow rate of the river with its multiple excess over the flow rate of drainage water (q/Q = 0,0002), the maximum permissible concentration can be reached in the control range, or the actual concentration exceeds the standard is 1,2 – 2 times lower than that for the outlet. Accordingly, it is recommended that, when determining the amount of damage caused to a water body from the discharge of drainage water, be guided by the actual concentrations in the control range, and not in the drainage water discharge range.

Heavy metals, organics and radioactivity in soil of western Serbia

Topicality. In the conditions of ever-increasing technogenic pressure on the environment, the study of the influence of In the context of the growing anthropogenic load on the environment, studying the influence of abiotic factors on the translocation of heavy metals in the soil-plant system is of great practical importance for the agricultural sector. In the southeastern industrial region, the environmental safety of crop production largely depends on the heavy metal accumulation in plants and their translocation depends on both soil properties and climatic factors. Purpose. To investigate the effect of agroclimatic conditions in the eastern part of the Northern Steppe of Ukraine on the content of heavy metal mobile forms in soil and their translocation into spring barley grain. Materials and methods. Research was conducted in the field crop rotation of the Donetsk State Agricultural Research Station of NAAS on the Stepovyk variety in 2018–2022 with using field, laboratory, mathematical and statistical methods. Results. The highest increase in the acid-soluble zinc content was observed under increasing soil moisture. Under dry conditions in 2020, the acid-soluble zinc content was 45.3 mg/kg, while under excessive moisture conditions in 2022 it increased by 8.5 mg/kg or 18.8 %. The content of all studied heavy metals in spring barley grain did not exceed the maximum permissible concentration (MPC) with increasing soil moisture. The content of the studied heavy metals in spring barley grain under increasing soil moisture did not exceed the maximum permissible concentration (MPC). With increasing moisture availability, there was a tendency to increased copper content (by 8.2–9.9 %). The zinc accumulation in spring barley grain increased from 24.2 mg/kg to 28.9 mg/kg, or by 19.4 % in the excessively wet year of 2022 compared to the dry year of 2020. The cadmium content increased by 0.02 mg/kg, which is 40 %. Conclusions. Hydrometeorological conditions affect the content of heavy metals mobile forms in the soil and their translocation into spring barley grain, which necessitates the implementation of methods to reduce the environmental risks of heavy metal contamination of plant products under conditions of excessive wetting and real anthropogenic load. Key words: spring barley, agroclimatic conditions, soil, grain, content of heavy metals

This paper presents the results of the ecological state study of oxbow Ishimchik, located in Ishim, Tyumen Region. The paper presents data on the nitrogen-containing ions concentrations dynamics in water samples of oxbow Ishimchik over the summer-autumn of 2017, the content of which is an important indicator of the water chemical composition. The presence of nitrate ions, nitrite ions and ammonia in high concentrations in the samples usually indicates that the reservoir suffers from contamination by household, agricultural and industrial waste. In 2016 and 2017 a large amount of water from heavy floods came to the oxbow, which could significantly increase the concentration of mineral forms of nitrogen. The main concern is the flood of 2016 as to stop the Ishim private sector flooding a channel was dug for discharge of floodwaters from the town-affected part into the oxbow. To determine the content of nitrogen-containing ions, the photometry method was used. The results of a chemical analysis show that the content of ammonium and ammonia cations (total), nitrite anions and nitrate anions is less than maximum permissible concentration as well as there is a change in the prevailing mineral form of nitrogen from redoxidized to oxidized.
