The contribution of anthropogenic mineral aerosol dust has been of interest to understand the impact of dust aerosols on climate, and the health of workers occupational exposure. Several studies have been investigated the physical and chemical properties mainly in particulate matter. However, the characterizations have not extended diameters below to 1.0 μm. In this study, it described chemical composition and shape measurements of individual aerosol particles with 50% cut-off diameters less than 1.1 μm emitted at ceramic-tile manufacturing. Four emission sites of process were selected, and their samples were collected using a cascade-impactor, investigated using X-ray diffraction, energy dispersive X-ray spectroscopy, and digital image processing, where the data were analysed applying a combination of principal component and cluster analysis. Particles of tectosilicate （quartz, zeolite）, phyllosilicate （illite, montmorillonite）, and inosilicate （calcium silicate） were founded in all sampling sites; also, silicates mixed with transition metals oxides used as pigments （e.g., Fe, Ti, Co, Ni, Zn and Mo）. Silicates were granulated and flat crystals with a transparent, translucent appearance; otherwise, the mixture had flake shapes and opaque appearance. Analyses of multivariate data showed that the process stages emissions were related with specific composition and shape suggesting the use three measurements related （1） the internal axis, （2） roundness and （3） roughness to isolate particles shapes, and the presence of transition metals oxides as emissions tracer of the ceramic industry.

Research was done with the objective of evaluating the quality of water supplied to the potable water system in Hidalgo Del Parral, which comes from two main supply sources： wells from ＂Valle del Verano＂, which provide water to the east side of the city, and the Water Treatment Plant, which receives water from different mines and supplies the west side of the city. When this plant is overcome on its capacity of treatment, a part of the water from the mines is fed directly to the northwest part of the city. The metals lead （Pb）, chromium （Cr）, cadmium （Cd）, zinc （Zn）, and arsenic （As） were analyzed by atomic absorption （AA） technique, based on the United States Environmental Protection Agency （EPA） Method 7000B （Revision 2, February 2007）. The digestion process was done according to the guidelines established in Method NMX-AA-051-SCFI-2001, Analysis of Water-Determination of Metals by Atomic Absorption, developed by the National Standardization Technical Committee for Environmental Protection （Mexico）. The samples were collected from the following points： 13 wells and 2 re-pumping stations of ＂Valle del Verano＂, the inlet and outlet of the Water Treatment Plant, and domestic faucets. The east side of the city, supplied by the wells of ＂Valle del Verano＂, is metal-pollution free. The water that comes from the mines contains high concentrations of As, Zn, Cd and Pb, with levels that can get to 0.12, 32.6, 0.26 and 3.5 mg/L, respectively. This water pollution generated by mining can be concluded from the high levels found in the domestic samples in which, for several points, the concentrations exceed the parameters set by the current guideline. According to the results, it is vital to set a plan of remediation for the water that comes from the mines, because there is a great risk for health in the consumotion of this water.

The US government constantly repeats that the country’s economy has solid foundations and that it is growing, even the current president announces that his country’s economy is the strongest in history, but the truth is that there are macroeconomic indicators that contradict it. The United States is experiencing a structural crisis of long evolution that is reflected in colossal indebtedness, in the concentration of wealth, the increase in poverty, and in the trade and budget deficits. During the second administration of President Obama, the ratio of debt to Gross Domestic Product (GDP) reached 100% and since then, the amount of debt has continued to increase. With the arrival of Donald Trump, the US economy registers historical deficits and the debt figure has already exceeded 21 trillion dollars, which augurs in the medium term a decline in GDP growth and a potential recession, but in the long term and not reversing this trend could present a financial catastrophe. This situation will negatively impact other indicators which could generate a climate of uncertainty, nervousness, and instability that will make the crises of 1929 and 2008-2009 pale.

Russia’s invasion of Ukraine has significantly altered the pattern of alliances and geopolitical balances on the European continent to such an extent that countries like Finland and Sweden that have traditionally remained neutral are now applying to join the North Atlantic Treaty Organization(NATO).These two countries fear that Russia,which is currently trying to reposition itself,could try in the near future to invade these two Nordic countries to prevent the West(European Union,United Kingdom,and United States)from increasing its military presence and its military force in the Scandinavian peninsula and in the Baltic *** enlargement that the European Union(EU)has carried out since the 1990s,and that has also meant the expansion of NATO,has been viewed with great concern by the government of Vladimir Putin,who considers that the United States and the European Union did not fulfill their commitment to former Russian President Mikhail Gorbachev to respect the sphere of influence of the former Union of Soviet Socialist Republics(USSR).Within the framework of this geopolitical confrontation,Helsinki and Stockholm do not want to run the risk of being invaded by the Russian army,which is why they seek to take advantage of the principle of collective security that NATO membership would grant them.

The Mexican oregano ＂Lippia berlandieri Shauer＂ is a versatile plant, for multiple purposes and high potential adaptative capabilities. To evaluate the possibility to use oregano as a cover surface on tailings deposits and thereby mitigate the emission of particulate material with metals content, an experiment was carried out comparing the plant growing rate over a period of six-month in four substrates： tailings, vermicompost, ＂soil＂ of the region and a mixture of ＂tailings plus vermicompost＂. The statistical analysis shows a significant difference between treatments, resulting in the ＂soil＂ substrate with the best performance, followed by the mixture of＂tailings plus vermicompost＂ treatment. The low permeability oftailings strongly affects the adaptability and growth of the oregano plant; however, the adaptation possibilities increase in the mixture oftailings with vermicompost or ＂soil＂ of the region.
