In the Recôncavo of Bahia (located between 12 degrees 33' and 13 degrees 10'S and 38 degrees 00'and 39 degrees 00'W), there are significant discharges of SO(2) and NO(x) due to local, industrial and urban activities. The incoming air masses from the Atlantic Ocean are enriched with seaspray, which neutralizes part of the rain acidity. The extent of...
To determine the blood lead levels in children living near an inactive lead foundry in the city of Santo Amaro da Purificação, state of Bahia, in September of 1998; and to identify factors associated with differences in these levels.
Cross-sectional study with children between 1 and 4 years of age living within 1 km of the lead foundry. Mothers or...
In a tropical coastal area. During 6 months the composition of rain samples collected simultaneously over 24h with an open collector and with an automatic opened collector (KFA - J lich Type) at 500m of the Atlantic coastline of Salvador were compared. All average concentrations were higher for the "total" samples than for the "wet only" samples, e...

... The authors concluded that the percentage of children at risk for lead poisoning in LAC is unknown and probably underestimated. The review included seven studies performed in Brazil from 2000 to 2014 that evaluated BLLs (Carvalho et al., 2000(Carvalho et al., , 2003Paoliello et al., 2002;Freitas et al., 2007;Mattos et al., 2009;Almeida et al., 2010;Ferron et al., 2012). Almost all Brazilian studies included a small number of participants, with a minimum of 47 and a maximum of 850 children. ...

... Rainwater composition is directly related to the level of local emissions, pollutant transport, climate conditions and drop size, which influences the rainout (in-cloud scavenging) and the washout (below-cloud scavenging) of pollutants (Baron and Denning, 1993). Precipitation chemistry has already been studied in many different places, including rural and urban areas around Europe (Alastuey et al., 1999;Al-Momani, 2003;Hontoria et al., 2003), Brazil (Campos et al., 1998;de Mello, 2001;Lara et al., 2001;Flues et al., 2002;Migliavacca et al., 2004) and other places in the world (Tanner, 1999;Bravo et al., 2000;Halstead et al., 2000;Seto et al., 2000;Kulshrestha et al., 2003). Thus, systematic observations of the chemical composition of precipitation are needed to investigate the changes and other characteristics of atmospheric pollution in this region (Xu et al., 2011). ...
... One example is the region of Santo Amaro (State of Bahia, Brazil), where a lead smelter operated for 33 years before closing in 1993. It has been reported that some children living close to the former plant have high levels of Pb and Cd in their blood (Carvalho et al., 2003). ...
... The pH value can vary depending on the ions interaction in suspension (Zhang et al 2008). The presence and quantity of these ions are a consequence of the atmospheric air circulation and the emitting source conditions (Campos et al 2007). ...
