Conception And Development Of A System Used To Organize And Facilitate Access To Environmental Information

“…A study performed by Santos Filho et al (2003) shows that, among the residents of Lixão dos Pilões, the average HCB concentration in the blood was 4.66 µg/L, 155 times higher than the average of the control population (0.03 µg/L). For DDT, the average content among the residents from Pilões was 3.71 µg/L, twice higher than the average found in the control population (1.85 µg/L).…”

“…Even after deactivation of this clandestine dumping site, the area continued to be occupied, giving rise to research concerning the effects of contamination by organochlorides in that population (Santos Filho, et al, 2003). The study covered 238 people living in the area occupied by such dumping site and surroundings, analyzing the concentration of organochlorides (hexachlorobenzene, hexachlorocyclohexane, DDT, Aldrin, Dieldrin, Endrin, and others).…”

The expansion of agribusiness: harmful impacts of deforestation, pesticides and transgenics on bees

“…Além disso, muitas outras pesquisas têm demonstrado os efeitos nocivos dos agrotóxicos em organismos não alvo, tais como os vertebrados. Entre eles, destacam-se as alterações no sistema respiratório e hepático (Santos Filho et al, 2003;Kesavachandran et al, 2006), e nas funções fisiológicas, como mudanças bioquímicas que desencadeiam estresse oxidativo e danos citogenéticos (Tope et al, 2006;Jia & Misra, 2007). Os danos causados ao DNA, pelos agrotóxicos, podem desencadear processos carcinogênicos, anomalias morfológicas e alterações nos gametas, interferindo na fertilidade e na sobrevivência das populações (Bolognesi, 2003), além de gerar efeitos adversos crônicos na estrutura e dinâmica de populações e comunidades (Nacci et al, 1996;Kendall et al, 2001).…”

Temporal trends in concentrations and total serum burdens of organochlorine compounds from birth until adolescence and the role of breastfeeding

“…There are few studies assessing OCs exposure in adolescent subjects, and those available include study populations of a wide range of ages (between 7 and 20 years) and most of them were conducted more than ten years ago (Centers for Disease Control and Prevention, 2009;Cuadra et al, 2006;Linderholm et al, 2011;Newman et al, 2009;Santos Filho et al, 2003;Schettgen et al, 2011;Schroijen et al, 2008;Schulz et al, 2009) (Table 2). Compared to adolescents of European and North-American countries (Germany, Belgium, the US and Canada), participants of Ribera d'Ebre and Menorca have similar OCs exposure concentrations, with some exceptions (Table 2).…”

“…In any case, differences among study populations of westernized countries are generally minimal for all the compounds. Compared to low-/middle-income countries, the most remarkable difference is in relation to DDT and DDE concentrations, which are much higher in countries like Bangladesh, Nicaragua or Brazil (Cuadra et al, 2006;Linderholm et al, 2011;Santos Filho et al, 2003) ( Table 2). This is mainly due to the fact that in these countries a more recent (and intensive) use of this insecticide has taken place for agricultural purposes or to control the malaria vector, a practice still used in countries with endemic malaria (Bouwman et al, 2011;Gascon et al, 2012).…”
