Co2 Levels

  The effects of air pollution and global warming on human health have reached a dangerous level and this situation has become a critical environmental concern all over the world. The aim of the study was to explore levels of PM2.5 and CO2 emitted from the combustion engines of the road vehicles. The reason for choosing PM2.5 as one of the variables in this study is that it easily penetrates the lungs alveoli and is transmitted to other body organs by blood circulation. Exposure to PM2.5 from a few hours to a few weeks can cause serious cardiovascular diseases (CVDs), including death. The longer the exposure, the higher the risk for cardiovascular mortality. On the other hand, decrease in PM2.5 levels reduces cardiovascular mortality. Studies also show that PM2.5 is associated with diabetes, hypertension, and heart failure. The reason for choosing CO2 was its being as one of the six greenhouse gases leading to the climate change or global warming that threatens human health all over the world. Traffic emissions are the major source for both PM2.5 and CO2. That is why to understand the extent of the PM2.5 and the CO2 emissions from fossil fuel burning and thus their impact on human life is important. Studies show that while air pollution is high during peak hours, it is lower during off-peak hours. Moving from this fact, the discrepancies between peak and off-peak hours readings of the PM2.5 and CO2 levels, which were measured in Vancouver Downtown during 30 consecutive days, were observed. Air particulates PM2.5 were measured with the Dust Trak aerosol monitor and CO2 levels with Q Trak monitor. Results showed a statistically significant difference in the median concentration of PM2.5 between 5 p.m. and 12 a.m. (p=0.018). However there was no statistically significant difference in the median concentration of CO2 between 5 p.m. and 12 a.m. (p=0.84). Measures to reduce air pollution, particularly through reducing PM2.5 and CO2 levels, especially in urban settings, can help reduce the risks of global warming (CO2 effect) and have positive effect on public health issues by preventing or reducing the risks of occurrence of many diseases, and their fatal consequences in some instances, caused or triggered by exposure to air pollution. Both national governments and international agencies should support the scientific research the results of which will inform the public health policies and regulations that will promote cleaner air and thus healthier societies by both implementing some enforcement measures and educating the public on the risks of air pollution and global warming and the relevant and available remedies. This study has been carried out to contribute to the efforts made to this end.

Decision Making Model

For certain types of foods, food vendors often label low-quality foods that are harmless to human health as foods of excellent quality and sell these falsely labeled products to consumers. Because this type of food poses no harm to human health, when public health units discover their act of false labeling or food adulteration, vendors are only penalized with a fine rather than having them assume criminal liability. Upon discovering vendors act of falsely labeling food, public health units typically punish the involved parties according to the extent of false labeling. Such static protective measure is ineffective. Instead, the extent of punishment should be based not only on the extent of false labeling, but also on the frequency of food sampling as well as the number of samples obtained for food inspections. Only through this dynamic approach can food adulteration or false labeling be effectively prevented. Adopting the standpoint of the public sector in food safety management, this study developed a mathematical model that facilitates discussion on the aforementioned problems. Furthermore, we discussed how the supply-demand environmental factors of the food market are influenced by the administrative means that the public health units have used to prevent food false labeling.

ABSTRACTCOVID-19 epidemic is declared as the public health emergency of international concern by the World Health Organisation in the second week of March 2020. This disease originated from China in December 2019 has already caused havoc around the world, including India. The first case in India was reported on 30th January 2020, with the cases crossing 6000 on the day paper was written. Complete lockdown of the nation for 21 days and immediate isolation of infected cases are the proactive steps taken by the authorities. For a better understanding of the evolution of COVID-19 in the country, Susceptible-Infectious-Quarantined-Recovered (SIQR) model is used in this paper. It is predicted that actual infectious population is ten times the reported positive case (quarantined) in the country. Also, a single case can infect 1.55 more individuals of the population. Epidemic doubling time is estimated to be around 4.1 days. All indicators are compared with Brazil and Italy as well. SIQR model has also predicted that India will see the peak with 22,000 active cases during the last week of April followed by reduction in active cases. It may take complete July for India to get over with COVID-19.

Public health communication makes extensive use of a linguistic formulation that will be called the “no evidence” statement. This is a written or spoken statement of the form “There is no evidence that P” where P stands for a proposition that typically describes a human health risk. Danger lurks in these expressions for the hearer or reader who is not logically perspicacious, as arguments that use them are only warranted under certain conditions. The extent to which members of the public are able to determine what those conditions are will be considered by examining data obtained from 879 subjects. The role of “no evidence” statements as cognitive heuristics in public health reasoning is considered.

The Creation

The epidemic of the disease COVID-19, in Požeština in relation to China, where it originated in other parts of Croatia, appeared somewhat later, while Požega-Slavonia County in terms of total share in relation to other counties in Croatia remained relatively well , 16th place, out of a total of 20 counties, ie a smaller number of patients was recorded. In the conditions of public health danger to the health and lives of people with expressed uncertainty, citizens around the world were flooded with numerous information, about the disease, ways of prevention, treatment that at one point threatened to turn into an infodemia, as warned by the WHO. The importance of crisis communication in such conditions is of great importance, and how governments and headquarters communicate messages about the crisis to the public, which is discussed in the first parts of the paper and points out several inconsistencies and illogicalities in the actions of the state headquarters. prohibition and permission to make recommendations contrary to the epidemiologist’s recommendations. But more important than the recommendations of headquarters and governments, today are the recommendations and news transmitted by digital media, and especially the local ones that bring news and recommendations for the area where we live. Therefore, the aim of this paper was to investigate in the central part the significance of the local 034 Portal in the Corona crisis, and its monitoring of the crisis and its impact on the public. Research through several segments, it was found that the portal maintained the level of reporting on regular events and adjusted reporting on the Crown to the conditions and situation in the county, not leading to sensationalism, concern, fear, but was a carrier of preventive activities and a good ally in the fight. against the epidemic, that is, he followed the guidelines for informing the WHO and did not contribute to the creation of an infodemia.

The search conducted on "The impact of global warming (GW) on the public health (PH) increasing the bacterial causing infectious diseases (IDs) performed by experiment: Vector-borne diseases (VBDs) insects, Taif, KSA", the experiment used ants (Taif Tapinoma sessile), prepared, arranged appropriate nests and adjusted the temperature at (20, 25, 30, 35, 40 and 45°C), for a week of each zone. It revealed the behaviour as (normal, semi-normal and ab-normal), the mean of mortality rates were between (0-53.3%). The bacterial contents measured by the turbidity indicated the presence of multiplication, were between (0.109-0.328). The bacterial growth degrees by sings were between (+ - +++++) and percent between (12-100%). Colony Forming Unit/ml (CFU/ml) confined between (1.8X102-15.0X102)/mL. Through this experiment it turned out the GW had a significant role on the PH, helped the proliferation of bacterial pathogens that caused IDS. The conclusion wiped from the experiment that the extent degrees of GW disadvantages on the PH. The PH workers must take the "Preventive Health Prophylaxis Measures" (PHPMs) to protect the individuals from IDs by eliminating the VBDs of various types, monitoring the immunological situation of individuals, provided the vaccinations of IDs and preparing for complete PHPMs against any changes in the PH.

This chapter addresses how racism presents a clear threat to the health of populations. In 2018, President Donald Trump made racist comments toward countries with predominantly nonwhite populations. Why did the president’s racism matter for the health of the public? To answer this question, one needs to understand where health comes from. Health is the product of the social, economic, and cultural context in which people live. This context is also shaped by social norms that do much to determine people’s behaviors and their consequences. Changing these norms can produce both positive and negative health effects. On the positive side, changing norms can promote health, by making unacceptable unhealthy conditions and behaviors that were once common, even celebrated. On the negative side, changing norms for the worse can empower elements of hate in society. When a president promotes hate, it shifts norms, suggesting that hate does in fact have a place in the country and the world. This opens the door to more hate crimes, more exclusion of minority groups from salutary resources, and little to no effort to address racial health gaps.
