Abstract Sphagnum mosses are used for biomonitoring of air pollution. In 2019, samples were taken from two peat bogs in Germany and two in Slovenia to determine differences in their levels of potentially toxic elements (PTE). The Corona Virus Disease (COVID-19) lockdown caused global decrease in air pollution. Therefore, we repeated the monitoring in 2020 to see if this was also reflected in moss composition. Despite the variability within bogs and the areas, it is possible to distinguish the degree of air pollution between the two countries. The Harz mosses have higher contents of almost all elements and Slovenian Cr and Hg in 2020. Comparison of the PTE contents, their ratios to Sc and the enrichment factors show that the COVID-19 lockdown led to a decrease in long-range pollutants bound to finest particles and increased the influence of local soil dusting. The effect prevailed over lower precipitation in 2020 compared to 2019. Transport and industry continued to contribute significantly to contamination. Sphagnum mosses proved to be good indicators of the spatial and temporal extent of pollution. Even relatively short periods of lower air pollution are reflected in moss PTE contents.

The corona virus disease, otherwise known as COVID-19, is an extremely communicable and pathogenic viral infection caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), which emerged in Wuhan, China in December 2019 and has spread to almost all the countries in the world. The transmission of the virus is through touching of the nose, eyes, or mouth by a finger that has been contaminated through droplets on a surface when a carrier sneezes or coughs. Since the existing fingerprint devices are predominantly contact based, it implies that they can aid in the transmission of the virus. This paper discusses the application of fingerprint devices in notable places with high rate of COVID-19 infection as well as the threats to fingerprint technologies and the countermeasures. The need to change focus and orientation towards contactless biometric technologies as sure solution to the fear and animosity expressed towards contact-based fingerprint technology is also expatiated.

The pollution status of ten potentially toxic elements (PTEs), isotopic compositions (Cu, Zn, Pb), and the potential ecological risk posed by them were investigated in the PM10 fraction of road dust in Busan Metropolitan city, South Korea. Enrichment factors revealed extremely to strongly polluted levels of Sb, Cd, Zn, Pb, and Cu in the PM10 fraction of road dust, with Sb levels being the highest. Statistical analyses showed that the major cause for contamination with PTEs was non-exhaust traffic emissions such as tire and brake wear. Cu and Zn isotopic compositions of road dust were related to traffic-related emission sources such as brake and tires. Pb isotopic compositions were close to that of road paint, indicating that Pb was a different source from Cu and Zn in this study. No significant health risk was posed by the PTEs. Taking into account the total length of road in Busan, a high quantity of PTEs in road dust (PM10) can have serious deleterious effects on the atmospheric environment and ecosystems. The results of metal concentrations and isotopic compositions in road dust will help identify and manage atmospheric fine particle and coastal metal contamination derived from fine road dust.

Corona virus Disease (COVID-19) began with a report on December 31, 2019, in Wuhan City of China about pneumonia cluster cases that have not yet been identified. The number of COVID-19 cases has increased and has spread to almost all. The World Health Organization (WHO) has stated that COVID-19 is an international health problem and established as a pandemic. COVID-19 case in Indonesia was first reported on March 2, 2020, and spread in 34 provinces in Indonesia. Treatment and vaccination for the prevention of COVID-19 are still in the process of research. So far preventive measures such as maintaining distance, wearing masks, improving the immune system, and hand hygiene are expected to break the chain of transmission of COVID-19. The COVID-19 socialization aims to provide adequate information to the public about the dangers and efforts to prevent COVID-19 that can be carried out by individuals and the community. The socialization was held in Koja Village, North Jakarta on March 8, 2020. The activity was carried out by the Regional Management of Keluarga Alumni Universitas Gadjah Mada (KAGAMA) DKI Jakarta in collaboration with the Health Sub-Department and the Koja District Government, North Jakarta. The main part of the activity is the delivery of COVID-19 material followed by interactive discussions between participants and resource persons. Individual and community prevention efforts are very important in reducing the number of cases and breaking the chain of transmission so that cases do not increase.

Recently, air pollution alerts were issued in the Metropolitan Area of Aburrá Valley (AVMA) due to the highest recorded levels of particulate matter (PM2.5 and PM10) ever measured. We propose a novel methodology based on magnetic parameters and an epiphytic biomonitor of air pollution in order to improve the air pollution monitoring network at low cost. This methodology relies on environmental magnetism along with chemical methods on 185 Tillandsia recurvata specimens collected along the valley (290 km2). The highest magnetic particle concentrations were found at the bottom of the valley, where most human activities are concentrated. Mass-specific magnetic susceptibility (χ) reaches mean (and s.d.) values of 93.5 (81.0) and 100.8 (64.9) × 10−8 m3 kg−1 in areas with high vehicular traffic and industrial activity, while lower χ values of 27.3 (21.0) × 10−8 m3 kg−1 were found at residential areas. Most magnetite particles are breathable in size (0.2–5 μm), and can host potentially toxic elements. The calculated pollution load index (PLI, based on potentially toxic elements) shows significant correlations with the concentration-dependent magnetic parameters (R = 0.88–0.93; p < 0.01), allowing us to validate the magnetic biomonitoring methodology in high-precipitation tropical cities and identify the most polluted areas in the AVMA.

Abstract. Currently, almost countries around the world have contracted Corono Virus Disease (Covid-19). This Virus initially appeared in China, precisely in Wuhan City at the end of 2019. This Virus is very dangerous because of its transmission from humans to other people so fast that even now there is no drug or vaccine that can overcome the corona virus. Indonesia is no exception, which is increasingly increasing the number of COVID-19 cases. The existence of this plague certainly has a big impact in almost all aspects of economic, social, cultural, even education. Almost all levels of education that were originally carried out in schools are now switching online/online. This article aims to explain how the influence of independent character education on students during online learning. This study was conducted through literature study looking at the resulr of surveys ad journals from electronic media. The conclusion of this article is the inculcation of independent character during online learning in elementary school.

Abstract Background Severe acute respiratory syndrome (SARS) corona virus mediated CoVid19 (corona virus disease 19) pandemic is a global concern. At the present, almost all countries of the world are home to the CoVid19 infection with varying rate.Methodology To understand the role of alcohol consumption and rate of CoVid19 infection, we conducted a comparative statistical analysis using the top CoVid19 infected countries of the world and compared them with per capita alcohol consumption per year. In addition, a Google trend analysis was conducted to understand the sentiments of the people towards the search of alcohol.Results We found that higher alcohol consumption is not proportional to the higher number of CoVid19 infection and deaths. Google trend analysis for search of alcohol for last 12 months was found highest for Australia followed by New Zealand, Ireland, United States, and South Africa, suggesting sentiment of higher alcohol search also not related to the SARS CoV-2 infection and deaths.

The Republic

For the second time, the moss biomonitoring technique was applied to evaluate the deposition of potentially toxic elements in the Republic of Moldova. The study was performed in the framework of the International Cooperative Program on Effects of Air Pollution on Natural Vegetation and Crops. Moss Hypnum cupressiforme Hedw. samples were collected in May 2020 from 41 sampling sites distributed over the entire territory of the country. The mass fractions of 35 elements (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Se, Rb, Sr, Sb, Cs, Ba, Cd, La, Ce, Sm, Eu, Tb, Hf, Ta, Th, Pb, and U) were determined using neutron activation analysis and atomic absorption spectrometry. Comparing with 2015/2016 moss survey data, significant differences in the mass fractions of Cr, As, Se, Br, Sr, Sb, Cd, Pb, and Cu were found. Main air pollution sources (natural processes, transport, industry, agriculture, mining) were identified and characterized using factor and correlation analyses. GIS maps were built to point out the zones with the highest element mass fractions and to relate this to the known sources of contamination. Contamination factor, geo-accumulation index, pollution load index, and potential ecological risk index were calculated to assess the air pollution levels in the country. According to the calculated values, Moldova can be characterized as unpolluted to moderately polluted, with low potential ecological risk related to the degree of atmospheric deposition of potentially toxic elements. The cities of Chisinau and Balti were determined to experience particular environmental stress and are considered moderately polluted.
