TL;DR: The aim of this literature review was to summarise the knowledge of the behaviour, and toxicity on marine and freshwater organisms, of phenols as well as to try to select a series of sensitive biomarkers suitable for ecotoxicological assessment and environmental monitoring in aquatic environments.

TL;DR: The results indicate that the sensitivity of marine microalgae to phenol was dependent on some biotic factors such as cell size, ROS production, and phenol degradation ability in algal cells.

TL;DR: Isochrysis galbana MACC/H59 may be a suitable marine microalgal species for use in environmental restoration operations after accidental spills of phenol at sea.
Abstract: Isochrysis galbana MACC/H59 was screened from eight strains of marine microalgae to investigate its capability for phenol biodegradation. Batch incubation experiments were performed for 25 to 200 mg L−1 initial phenol concentrations. Five growth inhibitory kinetic models were used to fit the experimental data. The specific activities of phenol hydroxylase and catechol dioxygenase in I. galbana are measured. The results showed that phenol, at concentrations of less than 100 mg L−1, could be completely degraded in 4 days. The growth kinetics of I. galbana under different phenol concentrations were best fitted with a Yano model among five kinetics models tested. The values of substrate inhibition constant (117.59 mg L−1), limiting substrate concentration (183.90 mg L−1) and optimal substrate concentration (81.46 mg L−1) for phenol biodegradation of I. galbana were also obtained with the Yano model. The phenol biodegradation in I. galbana was mainly catalysed by intracellular enzymes. The ortho-pathway is significantly predominant over the meta-pathway in phenol metabolism in I. galbana. High concentrations of phenol significantly inhibited the activity of phenol hydroxylase, but had no obvious effect on catechol dioxygenase. Isochrysis galbana may be a suitable marine microalgal species for use in environmental restoration operations after accidental spills of phenol at sea.

TL;DR: GST and MDA in the gill and GST, GSH, SOD, DNA strand break level in the digestive gland showed significant correlation with PCA exposure, which indicated that these parameters can be used as sensitive biomarkers to indicate toxic effects from chloraniline leakage.
Abstract: As a hazardous chemical, p-chloroaniline (PCA) shows intensive adsorption and accumulation after entering the aquatic ecosystem, which can be enriched in organisms and cause damage. With the objective of achieving an integrated and mechanistic view of the toxic effects of PCA in the marine sentinel organism Ruditapes philippinarum, Manila clams were exposed to different concentration of PCA (0.5, 2 and 5 mg/L) for 15 days. Focusing on the gills, first targeting the toxic and digestive gland, the metabolic detoxification organ, we detected dose- and time-related changes inantioxidase activities and biomacromolecular damages in treated clams. Glutathione S-transferase (GST) activity and glutathione (GSH) contents were significantly induced, and superoxide dismutase (SOD) activity increased at the beginning of exposure and then decreased. The malondialdehyde (MDA) and protein methylation (PC) contents which represent lipid peroxidation and carbonylation of proteins, increased first with exposure time and then decreased in the digestive gland. DNA strand break levels were consistently higher than those in the control group. The digestive gland showed more sensitivity to the stress of PCA than the gills. GST and MDA in the gill and GST, GSH, SOD, DNA strand break level in the digestive gland showed significant correlation with PCA exposure, which indicated that these parameters can be used as sensitive biomarkers to indicate toxic effects from chloraniline leakage.

TL;DR: In this article, the adsorption performances of phenol onto porous carbon from Toona sinensis leaves were carried out, and the maximum adaption capacity was recorded as 325 MG/g for 800 MG/L of phenols at 25 ÂC. In kinetic and isotherm studies, the data were well explained by the pseudo second-order and Langmuir equations.
