On April 26th, 2005, an accident caused a leak of 60,000L of Diesel Oil Type "B", freighted by train wagons upstream on a mangrove area within Guanabara Bay, Southeast Brazil. After the accident, samples from animals with different biological requirements were collected in order to monitor polycyclic aromatic hydrocarbons concentrations for the following 12months. Sessile, mobile, carnivorous, omnivorous, organic detritus feeders, planktivorous and suspension feeders were some of the attributes compared. Concentrations of PAHs did not vary in relation to different dietary habits and the best response was from the sessile suspensivorous barnacles. A background level of <50microgkg(-1) was suggested based on the reference site and on values observed in the following months after the accident. The highest values of PAH concentrations were observed in barnacles in the first month immediately after the spill, decreasing to background levels after few months. Barnacles are suggested as a sentinel species.
2005 年 4 月 26 日,在巴西南部瓜纳巴拉湾的红树林地区,一列载有 6 万升 B 型柴油的火车车厢发生泄漏。事故发生后,收集了具有不同生物需求的动物样本,以便在接下来的 12 个月内监测多环芳烃的浓度。比较了固着的、移动的、肉食性的、杂食性的、有机碎屑食者、浮游生物食者和悬浮食者等属性。多环芳烃的浓度与不同的饮食习惯无关,最好的反应来自固着的悬浮食藤壶。根据参考点和事故发生后几个月的观察值,建议将<50μgkg(-1)的背景水平作为基线。泄漏后第一个月,藤壶中多环芳烃浓度的最高值,几个月后降至背景水平。藤壶被建议作为一种指示物种。
