Brazil’s mystery oil spill: an ongoing social disaster

The most extensive oil spill registered in tropical oceans (Brazil): the balance sheet of a disaster

“…The oil spill affected at least 57 coastal and marine protected areas (MPAs) on the Brazilian coast (Ladle et al 2020;Soares et al 2020a, b). The Conservation Units (Unidades de Conservação -in Portuguese) are protected areas that are included in two management groups in Brazil: strictly protected areas (or no-take/full protection) and sustainable-use protected areas (or direct and multiple uses) (Table 1).…”

Design of Infused-Liquid-Switchable Superamphiphilic and Flame-Retardant Hierarchically Porous Materials from Emulsion-Templated Technique

“…The increasingly serious oil pollution from oil spillages and industrial processes has been a worldwide problem and drives the development of technology for effective oil/water separation. , Among the reported technologies, emulsion-templated macroporous polymers (so-called polyHIPEs) attract increasing attention as effective materials for oil–water separation, owing to their readily controllable void and interconnected pore size, ease functionalization, and flexible synthesis. − Generally, in emulsion-templated technique, an emulsion with its internal phase occupying greater than 74.05 vol % of its total volume (named high internal phase emulsion, HIPE) is involved as template. − PolyHIPE is then generated by polymerization of the monomers in the external phase of the HIPE. ,− Removing the internal (droplet) phase leaves voids (typically tens of microns in diameter) in polyHIPE that are highly interconnected through multiple pores (typically microns in diameter) in the walls between neighboring voids. The polyHIPEs have found applications as flow-through supports, − adsorbent–absorbents, scaffolds for tissue engineering, − containers for controlled release, etc. − Recently, polyHIPE with its surface of special wettability has attracted tremendous attention and has been approved for highly efficient separation for the mixture of oil/water. , In this context, superhydrophobic–superoleophilic polyHIPE, capable of removing oil from free oil/water mixtures, is extensively developed via appropriate control of surface structures and chemical compositions. ,− However, the use of those materials in practice remains a challenge, especially in the case of oil–water separation of an emulsion.…”

A big data approach to identify the loss of coastal cultural ecosystem services caused by the 2019 Brazilian oil spill disaster

“…More than 5000 tons of oil residue were removed from the landscape, having reached more than 800 beaches across more than 3,000 km of coastline, with immediate impacts on biodiversity, tourism and food security (de Oliveira Soares et al 2020, Ribeiro et al 2020, Câmara et al 2021, Zacharias et al 2021. The vertiginous drop in tourism revenue and fish trade caused by this tragic event severely affected coastal communities' health, well-being and economies (de Oliveira Soares et al 2020), the effects of which may be felt for generations (Ladle et al 2020).…”
