In the present study, we applied forensic geochemistry to investigate the origin and fate of spilled oils like tarballs stranded at the beaches of Bahia, in northeastern Brazil, in September 2023, based on their fingerprints. Saturated and aromatic compounds were assessed by gas chromatography, and the oceanic surface circulation patterns were deciphered to determine the geographic origin of the spill. Contamination by petroleum represents an enormous threat to the unique, species-rich ecosystems of the study area.

Article Synopsis
- A mysterious oil spill impacted a large section of the Brazilian coast in 2019-2020, prompting a study to estimate the volume of oil released using the Spill, Transport and Fate Model (STFM).
- The research hypothesizes that the spill was caused by issues like tanker buoyancy problems, leading to a gradual leak of oil from the vessel into the ocean.
- The estimated spill volume ranged from 5,000 to 12,500 cubic meters, suggesting it could be the largest spill in Brazil since 2004, which strained institutional resources and led to socioeconomic challenges.
Occurrence and distribution of monocyclic aromatic hydrocarbons (BTEX) and the impact on macrobenthic community structure in Lagos lagoon, Nigeria.

The widespread distribution of petroleum products arising from the rapid growth of the petroleum industry in Nigeria has resulted in the pollution of the environment through oil spills involving leakages from tankers, pipelines, tank farms, and dumping of waste petroleum products. The impacts and distribution of major toxic components (benzene, toluene, ethylbenzene, and xylene (BTEX)) of petroleum products in water and sediment samples collected from sampling stations in the Lagos lagoon was investigated over a 2-year period (February 2009-July 2010). The distribution of benthic communities in the different sampling stations of the Lagos lagoon was assessed.
