The use of fossil fuels has been greatly increased since the eighteenth century with advent of the industrial revolution. Currently, the use of these fuels is responsible for, on average, 80% of energy generation in human society, producing large emission of pollutant gases and particulate material. Thus the transport sector is a major source of air pollution worldwide. This issue causes serious damages to the environment through phenomena such as acid rain, global warming and photochemical smog. Moreover, the emission of pollutants is also related to damages in human health. Brazil is a country with great territorial dimensions and its transport array is eminently by road, so it is a major consumer of fossil fuels, such as diesel, which has been producing serious environmental and social problems. Thus, this paper presents an analysis of the emission of gaseous pollutants and particulate matter from the transport sector (buses and trucks), gaseous pollutants such as NO2 and SO2 were detected in ppmv concentrations using electrochemical sensors. The composition constituents of the particulate materials emitted in diesel combustion and their respective concentrations were determined by X rays fluorescence spectrometry (XRF). The identified elements were: S, Fe, Si, Ca, Zn, P, Ni, Cr, Ti, Mn and Cu.

Exploratory study was conducted in the Crato Public Prison, State of Ceará, Brazil, aiming to understand the knowledge and experiences related to the preventive aspects of Sexually Transmitted Diseases (STDs) in the prison context. The target population of the study consisted of 14 female inmates, 10 of whom agreed to participate. Data collection occurred in June 2012 through recorded semi-structured individual interviews. We investigated quantitative, socio-demographic and sexual variables. In qualitative data analysis, we applied the Meaning Interpretation Method. The female vulnerability was aggravated by the early onset of sexual activity, lack of knowledge about STDs, non-adoption of preventive measures and history of prostitution. The following categories emerged from the qualitative assessment: Knowledge about STD/AIDS versus Personal Experience;Use of contraception as STD/AIDS prevention within the Public Jail;Habits of inmates: alcohol and tobacco;and Characterization of the conjugal visit area.
