“…Declining CvO 2 could reflect increased oxygen use by tissues. However, even though ventilatory activity was not recorded systematically in these fish, depressed ventilation was observed, and is in line with the reported narcotic actions of aromatic hydrocarbons (Patten, 1977;Correa & Garcia, 1990). In addition, fusion of secondary lamellae, gill hyperplasia and oedema, and increased secretion of mucus have been reported in fish exposed to petroleum hydrocarbons (DiMichele & Taylor, 1978;McKeown & March, 1978;Engelhardt et al, 1981;Poirier et al, 1986;Correa & Garcia, 1990;Prasad, 1991) and would interfere with gas exchange.…”

“…Petroleum hydrocarbons have been reported to cause structural damage to the respiratory lamellae of the gills (DiMichele & Taylor, 1978;Poirier et al, 1986;Correa & Garcia, 1990;Engelhardt et al, 1981;Prasad, 1991), as well as to have narcotic actions (Patten, 1977;Correa & Garcia, 1990). Such effects would be predicted to impede gas exchange, and result in hypoxaemia, which might be expected to stimulate release of catecholamines Ristori & Laurent, 1989;Randall & Perry, 1992).…”

Flounders Pleuronectes flesus with an implanted vascular catheter were exposed to a 50% dilution of the water soluble fraction (WSF) of Omani crude oil (c. 6 ppm total aromatic hydrocarbons) and serial blood samples taken to determine their endocrine status (cortisol, catecholamines and thyroid hormones) and the resultant and/or causal physiological (haematological, ionoregulatory and respiratory) disturbances. This resulted in a progressive increase in plasma cortisol concentrations from 3 h onwards (rising from 18 to 51 ng ml 1 after 48-h exposure), and increased plasma glucose concentrations indicating a generalized stress response. Plasma T 3 and T 4 concentrations of both control and WSF-exposed groups declined progressively over the experimental period; exposure to the WSF of crude oil further depressed plasma T 4 concentrations but not plasma T 3 concentrations relative to those of control fish. Plasma osmolality and sodium and chloride concentrations were stable in WSF-exposed fish, however, plasma potassium concentrations were increased significantly at the 24-and 48-h sampling points. The most profound physiological disturbance in WSF-exposed fish was a dramatic decline in blood oxygen content (CvO 2 ) (from 2·8 to 0·8 ml 100 ml 1 after 48-h exposure), which is likely to be the cause of the increased plasma noradrenaline concentrations from 3 h onwards. Increased noradrenaline is likely in turn to have been responsible for the significant increase in blood haematocrit and blood haemoglobin at the 3-h sampling point, although the dominant effect in the longer-term was a significant decline in both of these haematological parameters. 1996 The Fisheries Society of the British Isles

“…The lack of effect in this study is for instance in accordance with Milinkovitch et al () who observed no modification of SMR, AMR and AS in golden grey mullet Liza aurata (Risso 1810) after exposure to crude oil and dispersants, nor did McKenzie et al () find that organic pollutants affected metabolic rates of chub Leuciscus cephalus (L. 1758). In contrast, other studies have demonstrated an increase (Hose & Puffer, ; Correa & Garcia, ; Davison et al , ) or a decrease (Sharp et al , ; Serigstad & Adoff, ; Prasad, ; Davoodi & Claireaux, ; Christiansen et al , ) of AS in fishes after petroleum exposure. Fish contamination in these studies, however, occurred by an aqueous pathway (involving the water soluble fraction of petroleum), which may count for the contrasting results with the present study.…”

“…It is defined as the difference between active metabolic rate (AMR), which is the highest metabolic rate the organism can sustain, usually during maximal activity, and the standard metabolic rate (SMR), the metabolic rate necessary to maintain vital functions and measured under resting conditions at a known ambient temperature (Fry, ; Brett, ; White et al , ). AS is known to be modulated by pollutants (Sharp et al , ; Hose & Puffer, ; Correa & Garcia, ; Davison et al , ; Nikinmaa, ; Wilson et al , ; Lannig et al , ; Davoodi & Claireaux, ; Christiansen et al , ; Johansen & Jones, ). Focussing on PAH, Davison et al () reported that the Antarctic fish Pagothenia borchgrevinki (Boulenger 1902) doubled its AS after exposure to an aqueous fraction of petroleum.…”

Trophic contamination by pyrolytic polycyclic aromatic hydrocarbons does not affect aerobic metabolic scope in zebrafish Danio rerio

The effect of trophic exposure to pyrolitic polycyclic aromatic hydrocarbons (PAH) on aerobic metabolism of zebrafish Danio rerio was investigated. There were no significant differences in standard metabolic rate (SMR), active metabolic rate (AMR) or aerobic metabolic scope (AS) at any sublethal concentration of PAH in the diet of adult or juvenile fish. This suggests that under these experimental conditions, exposure to PAH in food did not influence aerobic metabolism of this species.

Carbon and hydrogen isotope fractionation of benzene during biodegradation under sulfate‐reducing conditions: a laboratory to field site approach

The microbial carbon and hydrogen isotope fractionation of benzene under sulfate-reducing conditions was investigated within systems of increasing complexity: (i) batch laboratory microcosms, (ii) a groundwater-percolated column system, and (iii) an aquifer transect. Recent molecular biological studies indicate that, at least in the laboratory microcosms and the column system, benzene is degraded by similar bacterial communities. Carbon and hydrogen enrichment factors (epsilon(C), epsilon(H)) obtained from laboratory microcosms and from the column study varied significantly although experiments were performed under similar redox and temperature conditions. Thus, enrichment factors for only a single element could not be used to distinguish benzene degradation under sulfate-reducing conditions from other redox conditions. In contrast, using correlation of changes of hydrogen vs. carbon isotope ratios (Lambda = Delta delta(2)H/Delta delta(13)C), similar Lambda-values were derived for the benzene biodegradation under sulfate-reducing conditions in all three experimental systems (Lambda(laboratory microcosms) = 23 +/- 5, Lambda(column) = 28 +/- 3, Lambda(aquifer) = 24 +/- 2), showing the robustness of the two-dimensional compound-specific stable isotope analysis (2D-CSIA) for elucidating distinct biodegradation pathways. Comparing carbon and hydrogen isotope fractionation data from recent studies, an overlap in Lambda-values was observed for benzene biodegradation under sulfate-reducing (Lambda = 23 +/- 5 to Lambda = 29 +/- 3) and methanogenic (Lambda = 28 +/- 1 to Lambda = 39 +/- 5) conditions, indicating a similar initial benzene reaction mechanism for both electron-acceptor conditions.
