“…Es probable que al inicio del experimento (día 147), la presencia de PC haya provocado que los estomas se cerraran, reduciendo la tasa fotosintética y de transpiración (Prasch & Sonnewald 2015, Castro-Mancilla et al 2019, Zhang et al 2019. Esta disminución de la conductancia estomática podría deberse a que el PC provoca daños en las membranas celulares, pues hay un bloqueo en los espacios intercelulares derivado de la formación de una capa de PC en el suelo que no permite la absorción de agua (Cai & Ma 2002, Rennenberg et al 2006, González-Mendoza 2013, Tansel et al 2015. En este sentido, se ha reportado que las raíces envían señales químicas para el cierre estomático cuando entran en un estado de estrés por sequía o salinidad (Chaves et al 2009).…”

“…Potencial hídrico y osmótico foliar. Durante el experimento las raíces y el suelo pudieron estar cubiertas con PC, causando una baja infiltración de agua (Oluwafemi et al 2008, Tansel et al 2015, Sari et al 2018, por lo que podría haber una disminución del potencial hídrico y osmótico foliar. Además, se encontró que el potencial hídrico fue similar al inicio y el final del experimento para ambas especies; sin embargo, el potencial osmótico se disminuyó al día 292, respecto al día 147 en plantas de T. rosea en los tres tratamientos del suelo contaminado.…”

Antecedentes: La presencia de petróleo crudo (PC) en el suelo puede conllevar la muerte de especies vegetales que no logran aclimatarse a estas condiciones. Preguntas: ¿Cuál será la respuesta fisiológica de dos especies arbóreas creciendo en un suelo contaminado con diferentes concentraciones de PC? ¿Cuál será su plasticidad fisiológica en este contexto? Especies de estudio: Haematoxylum campechianum L. y Tabebuia rosea (Bertol.) DC. Sitio de estudio: Tabasco, México; 2017. Métodos: Se evaluaron variables fisiológicas en dos especies arbóreas establecidas en suelos contaminados bajo tres concentraciones de PC (15,170 a 15,600 mg kg-1) durante 292 días; se midió la asimilación de CO2 (A), transpiración (E), eficiencia en el uso del agua (EUA), eficiencia cuántica del fotosistema II (Fv/Fm y FPSII ), tasa de transporte de electrones (TTE), disipación no fotoquímica de energía (DNE), potencial hídrico, osmótico y contenido de clorofila. Resultados: Se encontró baja plasticidad fisiológica en ambas especies; hubo un efecto hormesis donde, en la concentración más baja de PC, los individuos presentaron un desempeño fisiológico superior comparado con plantas del tratamiento control. En T. rosea se registró un incremento en A, E, FPSII, DNE y Fv/Fm y una reducción en la TTE hacia el final del experimento en todos los tratamientos. H. campechianum presentó un incremento en la concentración de clorofila al final del mismo. Conclusiones: Tabebuia rosea presentó mayor variabilidad en sus respuestas fisiológicas comparada con H. campechianum, lo que sugiere que la primera podría ser más vulnerable a la presencia de petróleo crudo en suelo.

“…The negative effect of the emulsified oil on the dendrometric characteristics of the plants (leaf area, stem length, stem diameter, and total dry biomass) was less pronounced with the oil emulsified with the bacterial surfactant. Tansel et al (2015) indicated that mangroves exposed to oil can themselves eliminate a certain amount of contaminants and that the flow of water through mangrove roots is similar to that of a membrane system, in which the interval of the available hydrostatic pressure allows water to transport itself through the structure of the plant, similar to nanofiltration. When oil is combined with a surfactant, the system allows the roots to absorb and transport water vertically through the plant without being obstructed, thereby helping the plants to maintain an adequate level of hydration and preventing their mortality from the toxic effects caused by the accumulation of oil and salt.…”

“…Stations have recently been established to develop research on how to minimize the negative impact of oil spills on these wetlands (Duke et al 2000; Tansel et al 2015; Duke 2016). One of the strategies used is biological restoration, which is aided by the use of microorganism‐synthesized substances, called biosurfactants (Patel et al 2015; Ojeda‐Morales et al 2016 b ; Geetha et al 2018).…”

Mangrove forests are ecosystems subject to contamination by oil spills. The objective of this study was to evaluate the development of Rhizophora mangle plants in soil contaminated with oil emulsified with surfactants. These ecosystems have diverse and economically valuable ecological functions. Mangrove soil and propagules were collected in southeastern Mexico. The propagules were sown under greenhouse conditions and the plants were grown for 3 months. Two bioassays were applied: (1) the soil was contaminated by oil emulsified with a biosurfactant synthesized by Azospirillum lipoferum, and (2) the soil was contaminated with oil emulsified with a surfactant based on pine essential oil. Emulsified oil was applied to the substrate in containers with 3-month-old plants until several concentrations were reached (0, 30,000, 40,000, 50,000, 60,000, and 70,000 ppm). Subsequently, 5 plants for each treatment were randomly extracted every 30 days for 12 months, and the stem length and diameter, root length, leaf area, and fresh and dry weights of the plants were evaluated. Plant development was evaluated through an analysis of variance and a test of means. At the end of the bioassay, the treatments with oil emulsified with pine oil yielded no surviving plants, whereas the treatments with oil emulsified with the biosurfactant yielded a 100% survival rate. Treatment with 30,000 ppm of oil emulsified with the biosurfactant yielded the greatest increases in the leaf area and total dry biomass. The heavy oil fraction concentration decreased by 93.9% with the 30,000 ppm treatment and by 82.64% with the 70,000 ppm treatment.

“…Mangroves are typically found along tropical and subtropical coastal regions,andtheyareimportantbecauseoftheirhighrateofprimaryproduction that supports a wide range of aquatic organisms (Odum and Heald, 1972;Tam et al, 1998;Liu et al, 2014;Wang et al, 2014;Tansel et al, 2015). This ecosystem can be affected both when oil reaches the coast (as mentioned above) and by direct release of contaminants, because this ecosystem is usually situated near urban development and human activities (Wang et al, 2014).Thedeteriorationoftheseareasiscausedbythedisorderedoccupation of coastal areas and the consumption of natural resources.…”

For experiments concerning the formation of oil-suspended particulate matter (SPM) aggregates (OSA), oil and sediment samples were collected from Campos Basin and six stations of Paraguaçu estuary, Todos os Santos Bay, Brazil, respectively. The sediments samples were analyzed for organic matter determined by the EMBRAPA method, nitrogen determined by the Kjeldahl method, and phosphorus determined by the method described by Aspila. The oil trapped in OSA was extracted following the method described by Moreira. The experiment showed a relationship between the amount of organic matter and OSA formation and consequently the dispersion of the studied oil. On the basis of the buoyancy of OSA and the ecotoxicological effects on pelagic and benthic community, the priority areas for application of remediation techniques are Cachoeira, Maragogipe, and Salinas da Margarida because of the large amount of oil that accumulated at the bottom of the experiment flask (5.85%, 27.95%, and 38,98%; 4.2%, 17.66%, and 32.64%; and 11.82%, 8.07%, and 10.91% respectively).
