“…A similar decrease in activity of other marine animals (shrimps and copepods) as a result of oil has been reported (Ekanem et al 2011, Jiang et al 2012. It has been suggested that the oil water accommodated fraction (WAF) is able to disturb the normal operation of physiological and biochemical systems (Jiang et al 2012). Most oil WAF is highly lipophilic and may be easily ingested by marine organisms.…”

“…Sea urchins have a huge surface area because water enters from the tube feet, the madreporite and other places throughout the body. The organic compounds (especially PAH) of oil WAF could easily accumulate in the animals via the feeding behaviour and surface contact (Carls et al 2006, Jiang et al 2012. Therefore, these toxic effects could be related to the toxicity of PAH.…”

Summary:Oil spills have a disastrous ecological impact on ecosystems but few data are available for the effects of dispersed oil on benthic marine organisms. In order to provide information for assessment, we analysed the hydrocarbon compositions of the mechanically dispersed water accommodated fraction (MDWAF) and the chemically dispersed water accommodated fraction (CDWAF) of No. 120 fuel oil, their bioaccumulation, and DNA damage related to oil exposure, using the sea urchin as a sentinel organism. The results show that the concentration of polycyclic aromatic hydrocarbon in the tissues of sea urchin exposed to the CDWAF is higher than that of those exposed to the MDWAF. The single cell gel electrophoresis assay results also indicated higher DNA damage from exposure to the CDWAF of oil. Thus, dispersants should be applied with caution in oil spill accidents. Keywords:No. 120 fuel oil; dispersant; sea urchin; bioaccumulation; DNA damage; subacute toxicity. Bioacumulación y toxicidad subaguda mecánica y químicamente dispersas de aceite combustible pesado de erizo de mar (Glyptocidaris crenulari)Resumen: El derrame de petróleo tiene un desastroso impacto ecológico en los ecosistemas. Sin embargo, hay una falta de datos de los efectos de aceite disperso sobre los organismos marinos bentónicos. Con el fin de proporcionar información de evaluación de su efecto, hemos analizado la composición de hidrocarburos de fracción disuelta mecánicamente en el agua (MDWAF) y la fracción disuelta químicamente en el agua (CDWAF) No. 120 de aceite combustible, su bioacumulación y daños en el ADN relacionados con la exposición al petróleo, utilizando el erizo de mar como organismo centinela. Los resultados muestran que la concentración de hidrocarburos aromáticos policíclicos (PAH) en los tejidos de erizo de mar expuesta en CDWAF es mayor que en MDWAF. También que la concentración de hidrocarburos aromaticos policiclicos (HAP) en los tejidos de erizo de mar expuestos en CDWAF es mayor que en MDWAF. El resultado del ensayo de la célula individual por electroforesis en gel (SCGE) también indica el mayor daño en el ADN en CDWAF de aceite. Por lo tanto, la aplicación de dispersantes en accidentes de derrames de crudo ha de hacerse bajo control.

“…Organisms living near their environmental tolerance limits are generally more susceptible to additional stressors such as exposure to an elevated concentration of a chemical toxicant. A chemical concentration may be sublethal to organisms living at optimal environmental conditions, but which may become lethal at suboptimal conditions (Jiang et al 2012;Osterauer and Köhler 2008).…”

We hypothesize that chemical toxicity to marine ectotherms is the lowest at an optimum temperature (OT) and it exacerbates with increasing or decreasing temperature from the OT. This study aimed to verify this hypothetical temperature-dependent chemical toxicity (TDCT) model through laboratory experiments. Acute toxicity over a range of temperatures was tested on four commonly used chemicals to three marine ectotherms. Our results confirmed that toxicities, in terms of 96-h LC50 (median lethal concentration; for the marine medaka fish Oryzias melastigma and the copepod Tigriopus japonicus) and 24-h LC50 (for the rotifer Brachionus koreanus), were highly temperature-dependent, and varied between test species and between study chemicals. The LC50 value of the fish peaked at 20 °C for copper (II) sulphate pentahydrate and triphenyltin chloride, and at 25 °C for dichlorophenyltrichloroethane and copper pyrithione, and decreased with temperature increase or decrease from the peak (i.e., OT). However, LC50 values of the copepod and the rotifer generally showed a negative relationship with temperature across all test chemicals. Both copepod and rotifer entered dormancy at the lowest temperature of 4 °C. Such metabolic depression responses in these zooplanktons could reduce their uptake of the chemical and hence minimize the chemical toxicity at low temperatures. Our TDCT model is supported by the fish data only, whereas a simple linear model fits better to the zooplankton data. Such species-specific TDCT patterns may be jointly ascribed to temperature-mediated changes in (1) the physiological response and susceptibility of the marine ectotherms to the chemical, (2) speciation and bioavailability of the chemical, and (3) toxicokinetics of the chemical in the organisms.

Abstract:In order to study the toxic effect of petroleum hydrocarbons on marine phytoplankton, Isochrysis galbana was investigated by using the index of 96 h-EC50 and population growth. The results showed that the 96 h-EC50 increased significantly (P＜0.05) when temperature rising from 15℃ to 25℃. The intrinsic growth rates (r) increased but the time to enter into the stationary phase shortened from 15℃ to 25℃, and the carrying capability (K) reached highest at 20℃. In addition, the 96 h-EC50 in the salinity of 31 is higher than that in other salinities and the carrying capability reached the highest level. Moreover, the 96 h-EC50 increased when the pH changing from 6.5 to 8.1, but decreased Aquatic Science and Technology ISSN 2168-9148 2015 when the pH more than 8.1. The results also show that the maximum (K) and (r), and the shortest time into stationary phases in the natural pH of seawater. It shows the minimum (K) in the low pH of 6.5. There is no significant (P＞0.05) between pH7.5 and pH 8.5. In conclusion, temperature, pH and salinity did influence the toxicity of petroleum hydrocarbon to the microalgae (I. galbana).
