“…However, high concentrations of Corexit 9500 (> 80 mg/L) appear to be required to have lasting cytotoxicity in mammalian cell lines (Zheng et al 2014). In fish, even with variations among species and life stage, gene homologues in newly-hatched medaka and yellow perch exposed to AWB and CLB CEWAF treatments with similar water TPAC concentrations appeared to follow similar trends in activation to the current study (Madison et al 2015(Madison et al , 2017McDonnell et al 2019) S9). Dilbits caused the same type of malformations observed in exposures of trout alevins to diesel, conventional crude, and heavy fuel oils (Schein et al 2009;Wu et al 2012;Martin et al 2014).…”

“…Concentration-related responses of cyp1a to dilbit have been noted previously. Despite variance in the size of responses among fish species, cyp1a mRNA consistently responded to oil in a concentration-specific manner, as shown by others (Kim et al 2013;Holth et al 2014;Adeyemo et al 2015;Madison et al 2015Madison et al , 2017Alsaadi et al 2018b;McDonnell et al 2019). For example, Madison et al (2015Madison et al ( , 2017 highlighted 15-to 30-fold increases in cyp1a mRNA levels in medaka less than 24 h post hatch in response to increasing WAF and CEWAF concentrations of AWB and CLB dilbit compared to non-exposed medaka.…”

“…FS was used for daily measurements of the concentration of petroleum hydrocarbons in test solutions using a scanning spectrofluorometer (Quanta-Master Fluorescence Spectrometer, Photon Technologies International, HORIBA Scientific, ON, Canada) equipped with a 75W xenon arc lamp and FelixGX Version 4.1.2.4995 software. The FS method has been used to measure individual PAH in water (Lin et al 2015) and in fish bile (Fragoso et al 1999), and waterborne concentrations of heavy fuel oils (Martin et al 2014), conventional crude oils (Greer et al 2012;Wu et al 2012), diesel oil (Schein et al 2009, and dilbits (Madison et al 2015(Madison et al , 2017Alsaadi et al 2018b;McDonnell et al 2019).…”

This study assessed the chronic toxicity of two chemically enhanced water accommodated fractions (CEWAF) of dilbits, Access Western Blend (AWB) and Cold Lake Blend (CLB), to rainbow trout alevins. Chemical dispersion was used to overcome the resistance to dispersion of dilbits and to generate test solutions that contained more and smaller oil droplets for increased partitioning of petroleum hydrocarbons into water.Test solutions were characterized by fluorescence spectroscopy (FS), a rapid and inexpensive analytical tool, to compare toxicity endpoints measured by fluorescence (TPH-F). Cumulative mortality and the prevalence and severity of malformations increased following exposure of alevins to dispersed dilbits. Toxicity curves overlapped for AWB and CLB when expressed as TPH-F and 22-24 d LC/EC50s ranged from 0.36 to 1.5 mg/L. Gene expression in alevins was also altered following exposure to dispersed dilbit, with relative cyp1a mRNA levels increasing up to 170-fold for AWB and up to 240-fold for CLB. AWB and CLB caused similar toxicity to rainbow trout alevins as light to medium conventional crude oils, and rainbow trout alevins were more sensitive than yellow perch, Japanese medaka, and fathead minnow embryos exposed to dispersed AWB and CLB. This research is the first study assessing the embryotoxicity of dilbits to a Canadian freshwater salmonid species.

This review covers selected 2019 articles on the biological effects of pollutants, including human physical disturbances, on marine and estuarine plants, animals, ecosystems, and habitats. The review, based largely on journal articles, covers field, and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing, and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, marine debris, dredging, and disposal. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and proliferation of data on the assimilation and effects of marine debris microparticulates. Several topical areas reviewed in the past (e.g., mass mortalities ocean acidification) were dropped this year. The focus of this review is on effects, not on pollutant sources, chemistry, fate, or transport. There is considerable overlap across subject areas (e.g., some bioaccumulation data may be appeared in other topical categories such as effects of wastewater discharges, or biomarker studies appearing in oil toxicity literature). Therefore, we strongly urge readers to use keyword searching of the text and references to locate related but distributed information. Although nearly 400 papers are cited, these now represent a fraction of the literature on these subjects. Use this review mainly as a starting point. And please consult the original papers before citing them.

An understanding of the risks associated with diluted bitumen (dilbit) transport through Pacific salmon habitat necessitates the identification and quantification of hazards posed to early life stages. Sockeye from the embryo to juvenile stage (8 months old) were exposed to four concentrations of the water‐soluble fraction of Cold Lake dilbit (summer blend; concentrations of 0, 13.7, 34.7, and 124.5 μg/L total polycyclic aromatic compounds). Significant mortality (up to 18% over controls) only occurred in the embryo to swim‐up fry stage. Impaired growth was seen in the alevin, swim‐up, and juvenile stages (maximum reduction 15% in mass but not fork length). Reductions in both critical (maximum 24% reductions) and burst (maximum 47% reductions) swimming speed in swim‐up fry and juveniles were seen. Alterations in energy substrate reserves (reductions in soluble protein and glycogen content, elevations in whole‐body lipid and triglyceride levels) at all stages may underlie the effects seen in swimming and growth. Dilbit exposure induced a preexercise physiological stress response that affected the recovery of postexercise biochemistry (cortisol, glycogen, lactate, triglyceride concentrations). The transcript abundance of the cytochrome P450 1A gene (cyp1a) was quantified in alevin head regions (containing the heart) and in the hearts of swim‐up fry and juveniles and showed a concentration‐dependent increase in the expression of cyp1a at all life stages.
