Recent arrivals of tar balls have been observed in several tropical beaches associated with the oceanic circulation that flows to the Brazilian continental shelf. Between August and September 2022, tar balls were collected in the northeastern coast of Brazil and analyzed. Nearly 90 % of the oils were colonized by barnacles, polychaetes, decapods, and algae. Most rafting organisms were Lepas anserifera with capitulum measuring 0.32 to 22.21 mm. Based on the growth rate of barnacles and the speed of the SEC it was estimated that tar balls were floating since July and August 2022 and traveled a maximum of 1938.82 km. The organisms and tar balls' possible origin is in the international waters, near to the meso-Atlantic ridge, known for oil tanker traffic. The tar balls, in addition to the oil-related impacts, can act as a vector of long-distance species dispersion, and it needs to raise an alert, considering the possible ecological impacts.
最近在与流向巴西大陆架的海洋环流有关的几个热带海滩上发现了焦油球。2022 年 8 月至 9 月,在巴西东北部海岸收集了焦油球并进行了分析。近 90%的油被藤壶、多毛类、十足目和藻类所占据。大多数漂流生物是有帽贻贝,头部长 0.32 至 22.21 毫米。根据藤壶的生长速度和 SEC 的速度,估计焦油球自 2022 年 7 月和 8 月开始漂浮,最远漂流了 1938.82 公里。这些生物和焦油球的可能来源是在国际水域,靠近大西洋中脊,那里有油轮交通。焦油球除了与石油相关的影响外,还可能成为远距离物种扩散的载体,需要引起警惕,考虑到可能产生的生态影响。
