Opis:
Czad - gaz zwany cichym zabójcą pojawia się w naszych domach w porze chłodów, głównie w pomieszczeniach ogrzewanych paliwami węglowodorowymi. Jego obecność świadczy o niesprawności ciągów odprowadzania spalin, dopływu tlenu do strefy spalania paliw oraz o usterkach instalacji wentylacyjnej. Wymienione przyczyny zagrożeń mają niejednokrotnie swoje podłoże w beztroskiej działalności człowieka w zakresie konserwacji instalacji grzewczych opalanych gazem, drewnem, węglem czy odpadami organicznymi, w tym nieprzestrzeganiu obowiązujących przepisów bezpieczeństwa związanych z właściwościami fizykochemicznymi i toksycznymi czadu. W artykule omówiono przyczyny powstawania zagrożeń związanych z obecnością czadu, skutki oddziaływania tego gazu na organizm ludzki, sposoby zapobiegania tworzeniu się czadu oraz ochrony przed zatruciem. Przytoczono także podstawowe przepisy prawne obowiązujące w Polsce w tym zakresie.
Carbon monoxide - also called the silent killer, is a gas that appears at our homes during the chill season, mainly in rooms heated with hydrocarbons fuel. Its presence may prove inefficiency of draughts accompanying the fumes, oxygen flow towards the fuel burning zone, ventilation malfunction and hermetic windows sealing. Causes of threats often find their basis in human carelessness towards the preservation of heat installations charred with gas, wood, carbon and organic wastes. The article presents the causes of threats connected to the carbon monoxide fumes appearances, consequences of its impact on humans, ways of preventing its appearance and protection from intoxication methods. Polish regulations in this field were also described.

Opis:
Objective: Our aim is to evaluate the validity of exhaled carbon monoxide (CO) and of a newly-created score as markers of Chronic Obstructive Pulmonary Disease (COPD). Materials and Methods: The CO level was measured in a derivation subsample of a cross-sectional study and linked to COPD diagnosis; its predictors were evaluated, and a scale was constructed. It was evaluated in a validation subsample and in a clinical setting. Results: Individuals with COPD had higher CO levels than healthy individuals. CO level signifi cant predictors were cigarettes per day, waterpipes per week, lower age, male gender, living close to diesel exhaust, heating home with the use of diesel, and having indoor family smokers. A score composed of CO predictors was able to signifi cantly predict COPD (Ora = 4–7.5). Conclusions: Coupled with the clinical judgment of physicians, this scale would be an excellent low-cost tool for screening COPD, in absence of spirometry.

Opis:
Many large cities in Europe are currently trying to reduce the amount of harmful substances for the residents. Road transport is also an important source of air pollution. One way to reduce pollutant production is to operate more environmentally friendly vehicles. The paper analyses data obtained during practical tests of a hybrid vehicle in urban traffic. The individual components of the exhaust gases are calculated in g/km and they are compared with the values for conventional vehicle propulsion. The data was obtained through a commercially available exhaust gas analyzer and a calculated amount of emissions produced from available data from the engine control unit. The results shown that using of this type of propulsion has its importance in cities with increased air pollution. During urban operation, the hybrid-powered vehicle was powered by an electric engine up to 67.70% (75.40% of the time). As a result of operating such a vehicle in the city, emissions of CO2, HC and NOx are significantly lower.

One of the wastes generated by PT Beton Elemenindo Perkasa is polystyrene foam waste. Processing of this type of waste is still done with open burning so it has an impact on health and the environmental quality degradation. One of the polystyrene foam waste processing technologies is by constructing a combustion furnace equipped with carbon filter. Activated carbon is one of the air filter media that can absorb harmful gases from the combustion process. The purpose of this research is to identify the effectiveness of carbon monoxide (CO) concentration reduction on active carbon contact system using variation of particle size. This research is a kind of an experimental study involving post test with control design. The number of samples was calculated based on the number of treatments and the number of repetitions in the study. This research used 2 kinds of treatment, including 20 mesh and 30 mesh in 9 repetitions. Independent T-Test statistical analysis showed a significant difference (p-value = 0.001) between the variation of particle size of activated carbon and the CO parameters with the average of the most effective reduction percentage on particle-sized active carbon of 30 mesh was 77.95%.

Opis:
Background: The aim of this study is to compare the amount of exhaled carbon monoxide which can be an indicator of the phenomenon of tobacco smoking among youngsters in a group of students of Wroclaw’s universities. Materials and methods: The study was performed on 347 students living in dormitories of four Wroclaw universities: Wroclaw Medical University, University of Wroclaw, University of Physical Education and Technical University. Every tested student underwent a measurement of quantities of exhaled carbon monoxide by a Micro Medical Smoke Check device. Every participant took part in an anonymous survey, which was divided into three parts (for smokers/non-smokers/ex-smokers) and included exposure to tobacco smoke, length of time smoking etc. Results: No difference in the amount of exhaled CO between students of particular universities was observed. The Smoke Check measurements are higher in actively smoking students compared to nonsmokers. The results are higher in students declaring passive smoking compared with those not exposed to tobacco smoke at all. No difference in level of CO between genders and particular age groups was observed. Conclusions: Despite higher health awareness, students of the Medical University and University of Physical Education reach for cigarettes as often as the other tested students. Male students smoke as often as female students and CO result was not dependent on age.
Wstęp: Celem pracy jest porównanie ilości wydychanego tlenku węgla przez studentów wybranych uniwersytetów we Wrocławiu, jako wskaźnika pomocnego przy ocenie zjawiska palenia tytoniu u młodzieży studiującej. Materiały i metody: Badanie przeprowadzono wśród 347 studentów zamieszkujących domy studenckie czterech wrocławskich uczelni: Uniwersytetu Medycznego, Uniwersytetu Wrocławskiego, Akademii Wychowania Fizycznego i Politechniki Wrocławskiej. Zbadano ilość wydalanego tlenku węgla z użyciem urządzenia Micro Medical Smoke Check. Każdy uczestnik wziął udział z ankiecie dotyczącej jego kontaktu z dymem tytoniowym. Wyniki: Nie zaobserwowano różnić w ilości wydychanego CO między studentami różnych uczelni. Wyniki były najwyższe w grupie osób aktywnie palących. Grupa osób biernie palących wydalała więcej CO niż osoby nie deklarujące narażenia na dym tytoniowy. Nie zauważono różnic między grupą mężczyzn i kobiet, jak i między różnymi grupami wiekowymi. Wnioski: Pomimo większej świadomości zdrowotnej, studenci Uniwersytetu Medycznego i Akademii Wychowania Fizycznego sięgają po papierosa częściej, niż pozostali. Kobiety okazały się palić równie często, jak mężczyźni. Nie zaobserwowano różnic w ilości wydalanego CO między płciami.

Opis:
Aiming to create more sustainable cities it is necessary to understand and manage different ecological factors which influence human health. One of such factors is black carbon (BC) in atmosphere, which currently is not commonly monitored by environmental monitoring systems. The aim of this research was to estimate by indirect approach the relation between eBC (equivalent of black carbon) concentration and other air pollutants in order to define approximate level of eBC in more efficient approach. The study was conducted in Wrocław (Poland) in October 2021, and combined data on eBC concentration (measured by microaethalometer), air quality (from national environmental monitoring system) and traffic (from municipal traffic management system). Quantile regression was used to assess the relationship between the concentrations of pollutants. The obtained results show that for rise 1 mg∙m-3 of carbon monoxide, eBC concentration rise between 4.2 and 8.0 μg∙m-3, depending on the period of a day. Precision of eBC concentration evaluation is influenced by sun light which results in higher precision of defining a scaling factor for night hours. Outcomes of this study constitute an added value to understanding of interconnections between different factors describing environmental conditions in cities and might be helpful for more effective environmental assessment of human habitats.

Opis:
Objectives Many research studies conducted in various toxicology centers point to drugs as the most common cause of intoxication. Long-term observations make it possible to clarify the nature of these poisonings. The aim of this study was to examine the trends and reasons of intoxication in patients hospitalized over a 10-year observation period (2005–2015), as well as to compare the number of patients poisoned with nonsteroidal anti-inflammatory drugs (NSAIDs), mainly over-the-counter (OTC) drugs. Material and Methods A retrospective observational study examined the medical documentation of patients hospitalized in the Department of Toxicology and Internal Diseases of the T. Marciniak Lower Silesian Specialist Hospital in Wrocław in 2005–2015, including the analysis of the causes of intoxication as well as total poisoning-related death statistics. Quarterly and annual analyses of the numerical data, and comparisons of the frequency of poisonings were included. The patient population from the area of Lower Silesia, Poland, was examined. Results The number of hospitalized patients has increased, with attempted suicide being the leading cause of death. Male intoxication and mortality have been found to predominate. Drugs are the most common cause of poisoning, and among these the most common are sedatives and psychotropic drugs. Intoxication due to NSAIDs, especially OTC drugs, increased significantly in the observation period. In 2005 no fatal cases were reported as a result of NSAID intoxication, while in 2015 mortality significantly increased to 43%. Conclusions The lack of a common trend in poisonings is observed but the number of hospitalized patients has increased, especially among young people, which is consistent with global trends. Drugs are the most common cause of mortality, and a significant increase in NSAID (mainly OTC) poisonings in particular indicates the growing prevalence of an uncontrolled use of these drugs.

Abstract: Poor supply of electricity to different settlements over the years in Nigeria has forced building occupants to shift to dependence on generators. This study thus determined outdoor and indoor carbon monoxide levels of generators used in both residential and commercial buildings and assessed its impact on the users and the environment. The study was carried out in Ibadan Metropolis, Nigeria, which was divided into core, transition and suburban zone respectively. Five (5) residential and commercial buildings respectively were purposively selected in each of the zones of the study area. The HT- 1000 digital LCD carbon monoxide meter was used to take measurements of the emissions of carbon monoxide with conformity to NESREA AND OSHA standards. The outdoor emission levels of the carbon monoxide before or during the use of generators were taken at 0, 2 and 4 m respectively from the external walls of the buildings sampled and the corresponding indoor measurements were taken internally at 1.2-1.5m above floor area. The data collected were analysed with the use of statistical methods such as t-test, trend analysis and Kolmogorov smirnov test. The results showed that outdoor and indoor measurements of carbon monoxide emissions levels were highest in buildings in the core zone either before or during the use of generating sets. Reduced carbon monoxide levels during use of generators were obtained at distance limits beyond 2 m from external walls of buildings across zones of the study area. In view of the measurements taken, being above limits set by statutory bodies, during use of generators, and its attendant effects on the environment and building occupants, it was recommended that its users should be enforced to position them in enclosures located away from external walls of buildings and government should license only sales of generating sets with emission control mechanisms.

Cigarette smoking are the most important reasons for increased carbon monoxide (CO) level in exhaled air. During the experiment, the CO level in indoor air in room was measured. Outdoor air quality data including atmospheric CO concentration, obtained from the own measured and data from the weather platform “freemeteo”. The measurements were carried out with the following variants: outside air, a room ventilated without people, nonsmokers, smokers and non-smoking people, smokers entering the room after smoking cigarettes, smokers who smoke in the room. As proven by measurements, carbon monoxide carried in the lungs by smokers has low concentrations and should not threaten the health of non-smoking users of rooms. The maximum concentration of carbon monoxide in the room was 1.4 ppm. In the external air, the average concentration of carbon monoxide was exactly as much as reported in the literature – 0.3 ppm.

Opis:
The necessity of development of technical solutions that will allow to reduce carbon monoxide emissions of flue gases of industrial productions is substantiated. It is shown that the most rational design solution to the problem of carbon monoxide pollution during the firing of electrode blanks is the use of aerated concrete blocks with a catalyst, which can be quickly and conveniently located directly on the carbon material of the “green” electrodes pouring in the subfloor space of the firing furnaces. Modified by oxides of Mn4+, Fe2+, Fe3+, Cu2+, Cr3+ -catalysts based on aerated concrete were obtained. It is shown that in an empty reactor in the temperature range 200–400 °С the degree of conversion of carbon monoxide in the absence of a catalyst is zero. It is established that on the investigated catalysts based on aerated concrete 100% oxidation of carbon monoxide is achieved at a temperature of 390 °C in the case of using a mixture of catalyst powders 30% CuO + 70% MnO2, 40% CuO + 60% MnO2, 50% Fe (FexCr1-x) 2O4 + 50% MnO2; 50% Fe3O4 + 50 % MnO2. It is determined that the addition of ferrite catalyst powder in aerated concrete in a mixture or without manganese dioxide does not critically affect the mechanical properties of the products.

The aim of the research is to identify places with deteriorated air quality in the selected city. After an analytical analysis of the data, it is possible to propose steps that can be used to actively contribute to the reduction of air pollution, especially due to road traffic. Places where deteriorated air quality was identified were identified on the basis of practical measurements. Given that the measurement route was designed in a built-up area of the city with a large number of pedestrians, the research was primarily focused on the identification of particulate matters (PM) and the concentration of carbon monoxide CO. The measurements were performed repeatedly on a pre-defined route. The measurements were carried out repeatedly during the morning rush hour when traffic was congested on the roads. Based on the processing and evaluation of the measurements, the sections where increased values of individual emissions were recorded were determined. In this way, it is possible to precisely identify places where air quality deteriorates. The research conclusions provide support for planning the optimization of air quality management policies towards the creation of sustainable cities. The research results present the possibilities of identifying problematic sections from the point of view of emissions production. Critical places with regard to the production of emissions can be connected to places where a permanently increased movement of vehicles is observed.

The condition of the Coronavirus Disease 2019 (COVID-19) pandemic in 2020 characterizing DKI Jakarta, Surabaya, and Yogyakarta Provinces which have a high population density in 2019, necessitates implementing Large-Scale Social Restrictions (LSSR) to control or break the chain of the spread of COVID-19. The LSSR policy that limits community activities, be it business activities, transportation, and the industrial sector, will impact social activities and the environment due to the reduced intensity of community activities. Therefore, this study aimed to determine changes in the carbon monoxide (CO) levels in Jakarta, Surabaya and Yogyakarta during the pre-pandemic and during the pandemic. The method used is the tropospheric CO concentration extracted from the Sentinel-5P satellite data. The CO data were retrieved and calculated using Google Earth Engine. The COVID-19 pandemic reduced CO level by 19.7%, 14.9%, and 21%, respectively. The paired t-test shows no significant difference from before the COVID-19 pandemic, with a significance of 0.05. The highest pre-pandemic average and total CO concentration levels were 0.042 and 1.0198 mol/m2 in Yogyakarta, respectively, whereas the lowest during the pandemic were 0.02845 and 0.6828 mol/m2 in Surabaya. Overall, the three cities have a weak relationship between CO level and precipitation as well as temperatures and CO level.

The processes of the interaction of carbon material (thermoanthracite pouring) with a gas-air mixture in a heat chamber were studied while heating to 800–850°C. The influence of temperature, oxygen and carbon dioxide concentration on the formation efficiency of carbon monoxide, carbon dioxide, hydrogen and methane was determined. A pilot plant was created, which provided heating of the carbon material at the indicated temperatures and regulating the supply of air and carbon dioxide. It was found that a noticeable oxidation of the carbon material in the heat chamber in the presence of oxygen or carbon dioxide occurs at the temperatures above 500°C. Significant concentrations of carbon monoxide were formed at temperatures of 600–800°C. It was shown that when using gas mixtures with an oxygen content of 7–21% minimum concentrations of carbon monoxide are formed at an oxygen content of 14%. At temperatures above 500°C, the formation of hydrogen and methane in gas flows was noted. The methane yield increased with the decreasing oxygen content.

ObjectivesThe variety of clinical presentation on the topic of carbon monoxide (CO) intoxication ranges from slight headache to coma or death. YouTube allows patients to search not only for entertainment but also medical advice. Therefore, the aim of this study was to evaluate the content and quality of YouTube videos concerning CO poisoning as a source of knowledge for non-medical audience.Material and MethodsOn the December 8, 2020 a YouTube search was conducted for the following phrases: “carbon monoxide poisoning,” “carbon monoxide symptoms,” “CO poisoning,” “carbon monoxide asphyxiation,” “carbon monoxide intoxication” using the “incognito mode” and without attachment to Google Account. The search results were set as: “default” in the YouTube browser. The first 50 results were taken into consideration. Two raters, a specialist in emergency medicine and a specialist in clinical toxicology rated videos with Quality Criteria for Consumer Health Information (DISCERN), Global Quality Score (GQS) and Journal of the American Medical Association (JAMA). “VidIQ Vision for YouTube” plug-in was used.ResultsNinety-five videos were included. The interclass coefficient for DISCERN, GQS and JAMA scores were: 0.8, 0.74 and 0.62 reaching good and moderate reliability. The mean DISCERN/GQS/JAMA was 28.1 (SD 7.9), 2.5 (SD 0.8) and 1.1 (SD 0.7) respectively. Higher DISCERN/GQS/JAMA had videos providing information on: exposure time, treatment options, hyperbaric chamber indications as well as physician speaker (p < 0.05). Video Power Index was higher when the video contained animations and presented patients own history of CO exposure but not influenced the DISCERN/GQS/JAMA scores. Videos providing misleading information had a higher like ratio.ConclusionsThe overall video quality was poor indicating inappropriate educational and informative value for patients who search information about carbon monoxide poisoning.
