Abstract: the intentional burning of forest biomass commonly known as "ground-clearing fires" is an age-old and widespread practice in the country and is seen as a major contributor to global emissions of greenhouse gases. however, global awareness of their potential impact is relatively recent. the occurrence of large ground-clearing fires in the brazilian and international scenarios drew attention to the problem, but the measures taken to prevent and/or control the fires are still insufficient. in the amazon region, with distinct geographical and environmental features from the rest of the country, with its historic process of land occupation, every year the ground-clearing fires expose larger portions of the population making them vulnerable to its effects. in this context, this non-systematic review presents the papers written over the past five years about the fires in the brazilian amazon and respiratory illness. the main objective is to provide information for managers and leaders on environmental issues about the problems related to biomass burning in the amazon region.

Abstract: Oxidative stress is a biological process that occurs in response to an imbalance between prooxidant and antioxidant substances and has been described in the pathophysiology of more than 200 clinical disorders. In this study, we evaluate the relationship between genetic, demographic, social, environmental, and health factors and redox imbalance biomarkers in a group of children and adolescents environmentally exposed to atmospheric pollutants and mercury in the Brazilian Western Amazon. This is a cross-sectional study of the relationship between demographic, genetic, and socioenvironmental factors and serum concentrations of redox imbalance biomarkers (thiol groups, malondialdehyde, and glutathione S-transferase [GST]) in children and adolescents living in the municipality of Porto Velho, Rond?nia. The investigated factors were hierarchically organized into groups of variables and their relationship with redox imbalance biomarkers was estimated by a multiple linear regression model. Children and adolescents with asthma, with C-reactive protein values, with the polymorphic variant GSTP1, and exposed to indoor air pollution presented lower thiol serum concentrations when compared to those categorized in their respective reference groups. GST activity and malondialdehyde serum concentrations were positively related to weekly fish consumption and exposure to PM2.5. This study showed that enzymatic GST activity and malondialdehyde serum concentrations are positively associated with environmental factors, especially air pollution (β = 8.64 U/L for GST and β = 0.244 μmol/L for MDA in high exposure group; p-value < 0.01); while serum thiol concentrations presented an inversely proportional relationship with markers of general health status, such asthma (median: 0.45 mmol/L vs. 0.48 mmol/L; p-value < 0.05), acute inflammation (β = -0.25 mmol/L; p-value < 0.01), and positively with genetic factor (β = 0.12 mmol/L for Val/Val; p-value < 0.05).

Abstract: pneumoconioses make up a group of lung diseases related to exposure to mineral dusts in work environments. they represent a public health problem, considering that such diseases could already have been eradicated from brazil, if control measures had been taken in such environments. the aim of this research was to map the distribution of deaths due to pneumoconioses in the different geographical areas and states of brazil, by means of an ecological survey carried out in the working population older than 15 years. the preliminary results of this investigation in the brazilian macro-regions from 1979 to 1998 are presented. this study used mortality data provided by the mortality information system of datasus - data processing department of the unified health system, using the codes of the icd (international classification of diseases) 9 and icd 10. the results showed an increase in the mortality coefficient due to pneumoconioses per 1 million inhabitants per year along the studied period of time. by shifting from icd 9 to icd 10, the frequency of deaths doubled. we concluded that the mortality coefficients due to pneumoconioses do not reflect the problem properly, thus masking the transcendence and magnitude of the disease. in order to obtain more representative indicators, the actually exposed population and the territorial distribution of the disease have to be known.
Estudo das interna??es hospitalares por pneumoconioses no Brasil, 1984-2003

Abstract: introduction: pneumoconiosis represents a set of respiratory illnesses, such as silicosis, asbestosis, talcosis, beriliosis and others, which are known by their main causal agent. its incidence is probably high among exposed workers, but there is no epidemiological information such as historical series on hospitalizations in the several areas of the country. objective: to analyze hospital admissions due to pneumoconiosis in the period between 1984 and 2003 in all the domestic territory. method: morbidity information from the aih hospitalization system of datasus (national epidemiology center of the ministry of health) was collected, described and analyzed, for the period between 1984 and 2003, including all brazilian regions and states. idc-9 (1984-1997) and icd-10 (1998-2003) criteria were used. results: brazil presented a growth trend in hospital admissions between 1984 and 1991 with high rates of hospitalizations in all areas, followed by a reduction in the period between 1992 and 2003. the median of admissions for the period between 1984 and 1991 was higher in the center-west region and lower in the north region. in the second period, between 1992 and 2003, there was a change, with a lower median in the northeast and higher rates in the south region. discussion: the difference between the two periods can be explained by the diagnostic criteria used in these periods and by the way information was collected. the differences among regions probably reflect local work processes and the access of workers to health services. conclusion: the data show that actions to control and prevent these illnesses in the work environment are necessary. pneumoconiosis is an important public health problem whose numbers still do not adequately reflect the problem. if coefficients are calculated on the population effectively exposed, they will certainly disclose high morbidity illnesses.
