In Brazil, environmental accidents involving the oil industry occur every year. One of the main
accidents occurred in July 2000, at the President Getúlio Vargas Refinery - REPAR, in Araucária,
State of Paraná, which led to the contamination of soil and the Saldanha River watershed. Several
remediation techniques were established beginning in 2000 and the soil mesofauna were chosen
as indicators of soil pollution and of the effectiveness of remediation, due to their biodiversity,
high reproduction rates and sensitivity to environmental stressing agents. The following treatments
were monitored from October 2007 to February 2008: ploughed soil without vegetation (AM1);
phyto-remediaton using bracatinga (Mimosa scabrella) (AM2); soil washing (surfactant - LESS
and hydrogen peroxide) (AM3); use of heterogeneous catalysis with titanium dioxide (AM4);
use of heterogeneous catalysis (TiO2) with adsorption using peat (Sphagnum) (AM5); control
areas not contaminated and without any treatment effects (AM6 and AM7). Nine samples per
treatment were collected, using a soil corer (0-10 cm depth), and the mesofauna was extracted
in a Modified Berlese Funnel. Soil moisture, physical and chemical parameters were also
analyzed. Acari predominated in all the samples, but Acari and Collembola were less abundant
with ploughing (AM1) at all sample dates. Highest densities of Acari and Collembola occurred
in the control (AM7) in November 2007 and January 2008. In the treatments AM4 (October and
November 2007), AM5 (November 2007 and January 2008) and AM3 (January 2008) the Acari
and Collembola populations densities were almost as high as in the control (AM7). In the remaining
treatments populations were much lower then AM7, indicating a disruption in the biological
system. MenosIn Brazil, environmental accidents involving the oil industry occur every year. One of the main

O estudo teve como principal objetivo avaliar o metabolismo primário foliar de duas espécies lenhosas, Sterculia foetida e Bombacopsis glabra, de sementes ricas em óleo e amplamente encontradas em regiões com disponibilidade hídrica irregular. As duas espécies foram cultivadas em casa de vegetação a partir de sementes. Aos 140 dias após a emergência, 50% das plantas foram submetidas ao estresse salino durante 23 dias, recebendo diariamente uma solução de 100 mM de NaCl. As duas espécies rapidamente reduziram a sua condutância estomática e o potencial hídrico foliar, em relação às plantas controle. S. foetida e B. glabra apresentaram estratégias diferentes quanto ao conteúdo de pigmentos fotossintéticos e componentes do metabolismo do nitrogênio. S. foetida manteve seus pigmentos intactos após 23 dias de estresse, enquanto B. glabra aumentou o conteúdo de clorofila a e carotenoides. S. foetida apresentou alto teor foliar de K+ e uma relação Na+/K+ sem diferença nas plantas estressadas comparadas com as do controle. Portanto, S. foetida apresentou um melhor em balanço iônico, enquanto B. glabra investiu em fotoproteção. Assim, as duas espécies são alternativa potencial para serem cultivadas no Nordeste brasileiro, onde condições de estresse hídrico e salinidade são restritivas para culturas anuais. |
