We aim to evaluate the quality of the Guanabara Bay sediments and the ecological changes due to the PETROBRAS crude oil leak in January 2000. Twenty-six sediment samples collected in July 2000 and in February 2001 were analyzed for pH, dissolved oxygen, and foraminiferal composition. In the northwest and central parts of the bay, low oxygen dissolved values are related to waste discharges with the dominance of Buliminella elegantissima. In winter, near Iguaçu River, the pH of the sediment is low, therefore highly acidic. The acidity is responsible for the foraminiferal low diversity limiting the occurrence of species with fragile tests. On the other hand, thicker tests of Elphidium spp. disappeared last, therefore increasing its relative dominance in winter. In summer, this is a barren zone. The explanation lies in the continuous dissolution of tests that culminated with the total disappearance of these microorganisms one year after the accident.

The environmental quality of the marine area close to the Landulpho Alves Oil Refinery situated in Todosos Santos Bay (Bahia, Brazil) was assessed by statistical methods on foraminiferal assemblages, with species tolerant to low continental influence such as Ammonia tepida, Elphidium excavatum, Pseudononion atlanticum and Quinqueloculina spp., and to high organic matter such as Buliminella elegantissima and Bulimina marginata. We have found that Bolivina pulchella, Pseudononion atlanticum, Fursenkoina pontoni, Buliminella elegantissima, Bolivina striatula, Bulimina marginata, Quinqueloculina spp., Ammonia tepida, and Elphidium excavatum are opportunistic and tolerant to high levels of accumulated organic matter, and are associated to stations 6, 17, 18, 19, 21, 22, 23, 24, and 25, located mainly in the southern, outermost part of the Bay.

●严厉的消费者法律催生了数以干计的诉讼,愤怒的乘客可能会获得高达3000美元的赔偿在大多数国家,航班延误和行李丢失是航空旅行的不幸现实。在巴西,它们却有可能带来一笔意外收人。贝尔纳迪一施纳普律师事务所(Bernardi & Schnapp)的航空法专家、国际航空运输协会(IATA)在巴西的法律顾问里卡多·贝尔纳迪(Ricardo Bernardi)表示,在这里,不满意的乘客可以轻易将航空公司告上法庭,并有望赢得8000~1.5万雷亚尔(相当于1600~3000美元)的赔偿。
