A Study of Human Thermal Comfort, Ozone and Respiratory Diseases in Children  [PDF]
Amaury de Souza, Flavio Aristone, Luciane Fernandes
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.44060
Abstract: Objective: To assess the impact of air pollution and ozone on morbidity due to respiratory diseases among children from 2005 to 2008. Methods: The database was composed by daily reports on visits by children with respiratory diseases in health units of the Unified Health System (SUS) in the municipality of Campo Grande, MS, Brazil, by daily levels of ozone concentration measured by the Department of Physics, Federal University of Mato Grosso do Sul, and by daily measurements of temperature and relative humidity provided by the Agricultural Research Corporation-EMBRAPA Gado de Corte-MS. The relationship between respiratory diseases and ozone concentration was investigated through Generalized Linear Models (GLM) using the multiple Poisson regression model. The significance level α = 5% was adopted for all tests. Results: It was observed that the association between ozone (lagged by three time-steps) and attendance for respiratory diseases in children was statistically significant. The bio-meteorological variable Wind-adjusted Effective Temperature (lagged by four time-steps) was also significantly associated with diseases. Conclusions: The results suggest that the surface ozone concentration promotes adverse effects on children’s health even when pollutant levels are below the amounts permitted by law.

Abstract: backgraund: fear of adverse effects (ae) represents a frequent reason among healthcare workers (hcw) for not deciding to receive influenza vaccine. this investigation is carried out with the objectives of knowing the frequency of ae and the factors associated with them after the administration of influenza vaccines in the 2009-2010 season in hcw. methods: cohort study that included the 969 hcw vaccinated against seasonal influenza and the 693 hcw vaccinated against new influenza a (h1n1) virus during the 2009-2010 season in a tertiary hospital. to detect adverse effects, hcw was telephoned one week after vaccination. results: frequency of ae ranged between 24.5% of hcw who received only seasonal influenza vaccine and 82.6% of those who received vaccine against new influenza a (h1n1) virus. the most frequent ae were pain and general discomfort. none of the adverse effects was considered serious. age and presence of an adjuvant in the vaccine were associated with appearance of ae after administration of vaccine against new influenza a (h1n1) virus. conclusions: vaccines against seasonal influenza and new influenza a (h1n1) are safe; frequency of ae related to this one was high, especially if it contained an adjuvant. since none of the ae detected was serious, hcw can not justify his rejection of vaccination because of suffering the above-mentioned ae.
Fluoride in Tunisian Drinking Tap Water  [PDF]
Wiem Guissouma, Jamila Tarhouni
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.711070
Abstract: This paper presents a fluoride health risk characterization approach to identify the hyper-sensitive population of adverse effect like tooth decay, dental fluorosis and skeletal fluorosis. In this context, a sampling campaign has been done over 100 Tunisian water consumption points (tap). Laboratory analysis results show that the quality of drinking water is affected by high fluoride concentration level exceeding 2 mg·L-1. Over these samples, 7% of them present non-compliant with the Tunisian national standard (NT09.14) and the international guidelines (World Health Organization recommendations, WHO). The overtake cases are located essentially in southern Tunisian areas, i.e. Medenine, Gabes, Gafsa and Tataouine. One can highlight that groundwater, in these southern Tunisian areas, are naturally rich of fluoride. This is because of the aquifers geological and fossil nature. However, commonly northern and central Tunisian areas are characterized by low fluoride concentration level below 0.1 mg·L-1. These undertaken cases don’t meet the water quality requirement defined by WHO.
