“…26 Long-term exposure to minimal concentrations of air pollutant gases (such as pollutants from biomass fuels and kerosene) can easily affect the hematopoietic system by interfering in the formation of red blood cells and the process of formation of heme, during the formation of red blood cells. 27,28 Air pollutants from the burning of polluting fuels may lead to significant damage to red blood cells such as reduced hemoglobin concentrations, the number of erythrocytes, and hematocrit, thus leading to anemia. 29,30 High indoor air pollution is a known risk factor for structural lung diseases especially chronic obstructive pulmonary disease (COPD) and the resulting chronic hypoxia stimulates red cell production masking underlying anemia.…”

Background Indoor air pollution from different fuel types has been linked with different adverse pregnancy outcomes. The study aimed to assess the link between indoor air pollution from different fuel types and anemia during pregnancy in Ethiopia. Method We have used the secondary data from the 2016 Ethiopian Demographic and Health Survey data. The anemia status of the pregnant women was the dichotomous outcome variable and the type of fuel used in the house was classified as high, medium, and low polluting fuels. Logistic regression was employed to determine the association between the exposure and outcome variables. Adjusted Odds Ratio was calculated at 95% Confidence Interval. Result The proportion of anemia in the low, medium, and high polluting fuel type users was 13.6%, 46%, 40.9% respectively. In the multivariable logistic regression analysis, the use of either kerosene or charcoal fuel types (AOR 4.6; 95% CI: 1.41-18.35) and being in the third trimester (AOR 1.72; 95% CI: 1.12-2.64) were significant factors associated with the anemia status of the pregnant women in Ethiopia. Conclusion According to our findings, the application of either kerosene or charcoal was associated with the anemia status during pregnancy in Ethiopia. An urgent intervention is needed to reduce the indoor air pollution that is associated with adverse pregnancy outcomes such as anemia.

“…En cuanto al sistema cardiovascular, en el estudio de Badman y colaboradores se describen los efectos de la unión del monóxido de carbono a la hemoglobina modificando su conformación y reduciendo su capacidad para transferir oxígeno. La reducción en la disponibilidad del oxígeno afecta la función de diferentes órganos (especialmente los órganos diana, como el cerebro y el corazón), lo que puede generar retardo en la respuesta de los reflejos y confusión (26).…”

Mediante la disminución de los niveles de contaminación del aire los países pueden reducir la carga en morbilidad derivada de accidentes cerebrovasculares, cáncer de pulmón y neumopatías crónicas y agudas. Por lo tanto, el objetivo de esta investigación fue determinar los efectos a corto y largo plazo que tiene la contaminación ambiental sobre la salud de la población por medio de una revisión narrativa de tipo cualitativo y descriptivo. El método de búsqueda e identificación de los estudios se realizó por medio de las siguientes bases de datos electrónicas: Medline, Pubmed, Science Direct, entre otras; con un estado del arte de máximo 5 años posteriores a su fecha de publicación. De acuerdo con la búsqueda realizada en las bases de datos, se seleccionaron un total de 10 artículos en los cuales se encontraron diferentes efectos de la contaminación ambiental en la salud humana a nivel respiratorio, cardiovascular, hepático, neurológico, gestacional, inmunológico, entre otros sistemas a causa del material particulado encontrado en el ambiente como los son del PM 2.5, PM10 Y otros gases relacionados con la contaminación y los efectos sobre la salud. Los resultados de esta revisión narrativa confirman los efectos asociados a la contaminación ambiental a corto plazo y largo plazo del aumento de las concentraciones de las partículas contaminantes encontradas en el ambiente. Palabras claves: contaminación ambiental, partículas contaminantes, efectos corto plazo, efectos largo plazo, material particulado.

Estimation of Carbon Content in High-Ash Coal Using Mid-Infrared Fourier-Transform Infrared Spectroscopy

et al. 2023

The carbon content of different types of coal determines its utility in industries and thermal power generation. The most popular and widely used is the conventional method (ultimate analysis) to determine coal’s carbon content (C, wt.%), along with H, N, and S. In the present study, the authors attempted to analyze the carbon content (C in %) in coals via data from Fourier-transform infrared (FTIR) spectroscopy, which can be a promising alternative. As a reference, the carbon content in the coal samples, referred to as CCHNS (in wt. %), was determined from the ultimate analysis. The mid-infrared FTIR spectroscopic data were used to investigate the response of functional groups associated with carbon or its compounds, which were used to model and estimate the carbon content in coal samples (referred to as CFTIR, in wt %). FTIR spectral signatures were utilized in specific zones (between wavenumbers 4000 and 400 cm−1) from a total of 18 coal samples from the Johilla coalfield, Umaria district, Madhya Pradesh, India. These 18 coal samples were used to produce 126 Coal+KBr pellets (at seven known dilution factors for each coal sample), and the spectral response (absorbance) from each pellet was recorded. For model development and validation, the training set and test set were formed using a 17:1 split (K-fold cross validation). The carbon content in the coal samples was modeled using the training set data by applying the piecewise linear regression method employing quasi-Newton (QN) with a breakpoint and least squares loss function. The model was validated using an independent test set. A pairwise comparison of estimates of carbon in the laboratory from the CHNS analyzer (CCHNS) and modeled carbon from FTIR data (CFTIR) exhibited a good correlation, relatively low error, and bias (coefficient of determination (R2) up to 0.93, RMSE of 23.71%, and MBE of −0.52%). Further, the significance tests for the mean and variance using the two-tailed t-test and F-test showed that no significant difference occurred between the pair of observed CCHNS and the model’s estimated CFTIR. For high-ash coals from the Johilla coalfield, the model presented here using mid-infrared FTIR spectroscopy data performs well. Thus, FTIR can potentially serve as an important method for quickly determining the carbon content of high-ash coals from various basins and can potentially be extended to soil and shale samples.
