ABSTRACT This study reports biological effects of the July 1975 oil spill in the Florida Keys for a one-year period. Floating seagrass served as a natural sorbent for oil and stranded in the intertidal zone. A soluble component of oil, or possibly an organic cleaning solvent, leaching from this debris, was probably responsible for a mass mortality of subtidal echinoderms on the rocky platform. Several crab species were eliminated from the rocky shores, mangrove fringes, and Batis marsh communities for several months. Subtidal pearl oysters (Pinctada radiata) from the grass flat community suffered extensive mortalities, also attributable to a soluble component of oil. Red mangrove (Rhizophora mangle)seedlings on the fringe and in the mangrove swamp, sustaining greater than 50% oiling of their leaves, were killed. Dwarf black mangroves (Avicennia nitida) with greater than 50% oiling of pneumatophores also died, as did some where the substrate remained oiled one year later. Elevated temperatures, exceeding lethal limits for many intertidal organisms, were observed in oil-covered substrates. Oil persisted in the substrate of rocky shores and mangrove-marsh areas for at least one year after the spill.

Oil spill incidents are hazardous and have prolonged damage to the marine environment. Management and spill clean-up procedures are practical and rapid, with several shortcomings. Coco peat (CP) and coco fibre (CF) are refined from coconut waste, and their abundance makes them desirable for diesel spillage treatment. Using a filter-based system, the selectivity of coco peat sorbent was tested using CP, CF and peat-fibre mix (CPM). CP exhibited maximal diesel sorption capacity with minimal seawater uptake, thus being selected for further optimisation analysis. The heat treatment considerably improved the sorption capacity and efficiency of diesel absorbed by CP, as supported by FTIR and VPSEM–EDX analysis. Conventional one-factor-at-a-time (OFAT) examined the performance of diesel sorption by CP under varying parameters, namely temperature, time of heating, packing density and diesel concentration. The significant factors were statistically evaluated using response surface methodology (RSM) via Plackett–Burman design (PB) and central composite design (CCD). Three significant (p < 0.05) factors (time, packing density and diesel concentration) were identified by PB and further analysed for interactions among the parameters. CCD predicted efficiency of diesel absorbed at 59.92% (71.90 mL) (initial diesel concentration of 30% v/v) and the experimental model validated the design with 59.17% (71.00 mL) diesel sorbed at the optimised conditions of 14.1 min of heating (200 °C) with packing density of 0.08 g/cm3 and 30% (v/v) of diesel concentration. The performance of CP in RSM (59.17%) was better than that in OFAT (58.33%). The discoveries imply that natural sorbent materials such as CP in oil spill clean-up operations can be advantageous and environmentally feasible. This study also demonstrated the diesel-filter system as a pilot study for the prospective up-scale application of oil spills.

Conventional synthetic sorbents for oil spill removal are the most widely applied materials, although they are not the optimal choices from an economic and environmental point of view. The use of inexpensive, abundant, non-toxic, biodegradable, and reusable lignocellulosic materials might be an alternative to conventional sorbents, with obvious positive impact on sustainability and circular economy. The objective of this paper was to review reports on the use of natural-based adsorbing materials for the restoration of water bodies threatened by oil spills. The use of raw and modified natural sorbents as a restoration tool, their sorption capacity, along with the individual results in conditions that have been implemented, were examined in detail. Modification methods for improving the hydrophobicity of natural sorbents were also extensively highlighted. Furthermore, an attempt was made to assess the advantages and limitations of each natural sorbent since one material is unlikely to encompass all potential oil spill scenarios. Finally, an evaluation was conducted in order to outline an integrated approach based on the terms of material–environment–economy.

Peat moss, a well-known hyper-sorbent is now gaining attention for its utilization in oil-spill cleanup techniques because of its cost-effectiveness, biodegradability and relatively high oil absorption capacities. This review mainly emphasis on the characteristic features of the peat moss such as high porosity and large surface area which make it an efficient natural sorbent material for cleaning up oil spills. There are several products which have been developed from the peat moss and are commercially available in the market for oil spill cleanup.

Romanian Merino wool was tested as a natural sorbent for oil spill cleanup. Rebco crude oil placed in distilled water was used as an oily water model. Experiments of batch sorption were performed under various conditions. The effects of process factors, i.e., initial density of packed bed sorbent (0.05-0.99 g/cm3), initial volume ratio of oil and water (0.25 and 0.14 cm3/cm3), and contact surface between adsorbent and oily water, on wool sorption capacity (6.4-11.8 g/g) were evaluated. Experimental data were fitted using pseudo-first order rate and pseudo-second order rate models. Keywords: oil spill, kinetic model, sorption capacity, wool fibre
