Aerossóis de queimadas e internações hospitalares por doenças respiratórias em crianças no Estado do Pará.
(Universidade Federal do Pará, 2021-05-31) MOURA, Maurício do Nascimento; SILVA, Glauber Guimarães Cirino da; http://lattes.cnpq.br/4792139391237534; https://orcid.org/0000-0003-1105-7603; VITORINO, Maria Isabel; http://lattes.cnpq.br/4813399912998401; https://orcid.org/0000-0003-3253-5301
According to WHO, for every four deaths of children under 5 years, one is related to environmental pollution, which is equivalent to 93% of children living in environments with polluted atmosphere worldwide. This research investigated the variability of fires and hospital admissions for respiratory diseases in children under 9 years of age, in a region deeply marked by changes in land use across the planet, with consecutive years in the ranking of deforestation, followed by fire of forest biomass: the state of Para. Eighteen years of time series of climatic variables, PM2.5, AOD and health were analyzed for two Para municipalities located in regions with very different environmental and social characteristics, through an ecological study of epidemiological character. In general, the two places analyzed showed an increase in the hospitalization rate in the second semester of each year of the historical series, despite Santarem showing high numbers of these records throughout the year. The climate also played an important role in increasing the incidence of respiratory syndromes, because it makes the environment conducive to fire action, however, the results showed that years without significant climatic anomalies can also present high records of fires and PM2.5. When these relationships were analyzed in just one year and with a record of fires, a clearer combination between the investigated variables was found, with good statistical correlation, as well as a surprising and worrying increase in fires in the municipality of Santarem, even surpassing Maraba, a municipality that has always been ahead with the highest values of deforestation, fires and air pollution. Maraba perceives the effects of fires in advance, in general, two months before Santarem, and this situation is explained by the geographic location, degree of forest preservation, response to climatic fluctuations, industrial activity and public policy action. A sample taken from the time series showed that Maraba reaches, at the height of the dry season, attention and emergency levels for PM2.5, thus presenting low air quality. Santarem did not register alarming levels, but daily monitoring detected many days with levels above the permitted level, in accordance with the standards established by environmental legislation. The levels of pollution detected can increase the number of outcomes for respiratory diseases, overloading the state's public health system.

Padrões climáticos de precipitação e a produção de soja na Amazônia

In this research we studied the modulation of precipitation through ocean-atmosphere phenomena of large scale active in the Amazon region adjacent oceans and their intensities were known as represented by climate indices (SOI, PDO, NAO) numerical indicators. From a series of 32 years (1979-2010) of rainfall data in the GPCP grid points, we applied Empirical Orthogonal Function not rotated for monthly and annual scale, where spatial and temporal patterns and rainfall were obtained. The monthly EOF1 (58%) had a southern pattern associated rainfall in most part, to the action of synoptic scale phenomena. The monthly EOF2 (21%) also showed different patterns of precipitation, but orthogonal to the first, reflecting the effects of the cold phase of the North Atlantic Oscillation. However, in the monthly EOF3 (5%) the spatial pattern is represented by a zone precipitation pattern, reflecting the effect of ENOS and ODP. For the annual scale, both EOF1 (36%), EOF2 (16%) and EOF3 (10%) show zonal and meridional spatial patterns, which also reflect the effects of the Atlantic and Pacific Oceans. The three climate indices studied showed were present in the modulation of precipitation in the Amazon region. Among the municipalities belonging to the Hall of soybeans, Sinop-MT and MT-Smile were the locations that were more sensitive to climate variability in precipitation, both annual averages, as for the average rainy seasons each year analyzed, mainly by because of surface conditions. Itaituba-PA, Santarém-PA and PA-Paragominas showed positive growth trend of rainfall, with the latter located in eastern Pará, showed high correlation between local precipitation and the number of IOS, with a lag of 1 month and 2 months, by selected case studies.
