Abstract Whereas for extra‐tropical regions model estimates of the emission volatile organic compounds (VOC) predict strong responses to annual cycles foliar biomass, light intensity and temperature, tropical stand out as a dominant source year round, with only little variability mainly due cycle biomass drought‐deciduous trees. As part Large Scale Biosphere Atmosphere Experiment in Amazônia (LBA‐EUSTACH), remote secondary forest site was visited dry‐to‐wet season transition campaign, trace...
As part of the project LBA‐EUSTACH (European Studies on Trace gases and Atmosphere Chemistry as a contribution to Large‐Scale Biosphere‐Atmosphere experiment in Amazonia), we examined diel pattern isoprenoid exchange wet season 1999 at remote field site Rondônia, Brazil. The emission two tree species secondary forest was investigated by means dynamic branch enclosure system compared basis climatological variables like temperature light physiological parameters such assimilation,...
We measured atmospheric gas‐phase volatile organic compounds (VOCs) at the end of wet and dry season a tropical rainforest site in Rondônia, Brazil, using various sampling techniques such as trapping on different adsorbents or cryogenic combined with appropriate analysis techniques. The measuring sites were located inside forest biological reserve near Ji‐Paraná. Sampling was performed from 3 May 1999 to 17 24 September 2 November during “wet‐to‐dry transition” “dry‐to‐wet periods...
Traditionally the monitoring of atmospheric pollutants is aimed at managing accidents and short-term actions for protection human health on local regional scales. These networks required continuous measurements with high time resolution, involving costly equipment, operation maintenance. More recent simulations mathematical models scenario-building regional, continental global scales, as well studies environmental personal exposure are demanding three main types design, where need special...
As part of the project LBA‐EUSTACH (European Studies on Trace gases and Atmospheric Chemistry as a contribution to Large‐Scale Biosphere‐Atmosphere experiment in Amazonia), exchange formic acid acetic between vegetation atmosphere was investigated wet‐to‐dry season transition dry‐to‐wet periods 1999 Rondônia, Brazil. Direct measurements branch level mainly exhibited uptake for all plant species both seasons, although diel, seasonal, interspecies variations were observed. Even though other...
As a part of the LBA‐EUSTACH (EUropean Studies on Trace Gases and Atmospheric CHemistry as contribution Large‐scale Biosphere–Atmosphere experiment in Amazonia) project, exchanges formaldehyde (HCHO) acetaldehyde (CH 3 CHO) between Amazonian vegetation atmosphere were investigated by branch enclosures compared with gradient measurements during wet‐to‐dry transition dry‐to‐wet‐transition periods at remote forest site Brazil, 1999. Branch enclosure several tree species showed emission well...
To determine the blood lead levels in children living near an inactive foundry city of Santo Amaro da Purificação, state Bahia, September 1998; and to identify factors associated with differences these levels.Cross-sectional study between 1 4 years age within km foundry. Mothers or guardians 47 answered a questionnaire concerning ingestion clay, soil, plaster and/or other materials (pica), relevant epidemiological aspects. The concentration was determined by atomic absorption...
