There was a large difference in the tissue distributions of extractable organic chlorine (EOC1) and bromine (EOBr). Liver lipid had the lowest levels of EOBr and EOC1, of all the components investigated, and eggs had the highest levels of EOC1. Heart contained the most EOBr and EOC1 per unit lipid, of the tissues. The presence of a larger proportion of EOBr than EOC1 in bile suggests a higher rate of excretion of EOBr. The EOC1 concentratios found in cod egg lipids were about 5 times higher than the highest values previously reported for EOC1 in lipid.

The capabilities of the oxygen transport system of rainbow trout in supplying the increased oxygen demands in exercise, in a water tunnel at 9–10.5 °C, have been investigated by increasing the velocity of water flow, with a 1 h period between increments, up to the maximum swimming speed (critical velocity, U crit ). 2. At U crit , N O2 was elevated above the resting level by 7.5 times. The logarithm of N O O2 was linearly related to the swimming speed expressed as a proportion of U crit . V g increased in almost direct proportion to the increase in N O O2 . 3. Heart rate rose slightly at half U crit and reached a maximum, 1.6 times the resting rate, as U crit was approached. Ventral and dorsal aortic mean blood pressures rose by 60% and 20% respectively at U crit while their pulse pressures doubled. Central venous pressure was virtually unchanged. 4. P a, O a, O2 fell slightly during exercise but C a, O a, O2 was unaffected. On the other hand P v, O v, O2 halved and C v, O v, O2 ...

The capabilities of the oxygen transport system of rainbow trout in supplying the increased oxygen demands in exercise, in a water tunnel at 9-10-5 °C, have been investigated by increasing the velocity of water flow, with a 1 h period between increments, up to the maximum swimming speed (critical velocity, U CIlt). 2. At U crlt , N Oi was elevated above the resting level by 7-5 times. The logarithm of iV o was linearly related to the swimming speed expressed as a proportion of ?7 cr | t-^ increased in almost direct proportion to the increase in iV Oi. 3. Heart rate rose slightly at half U CIlt and reached a maximum, i-6 times the resting rate, as £/ crlt was approached. Ventral and dorsal aortic mean blood pressures rose by 60% and 20% respectively at U cni while their pulse pressures doubled. Central venous pressure was virtually unchanged. 4. P a0 fell slightly during exercise but C a O , was unaffected. On the other hand P f O i halved and Q O i fell from 3-17 (S.E. = 0-3) too-6(s.E. = 0-7) mmol/1. Cardiac output increased by about 3 times resting values. 5; The results are discussed and an attempt is made to estimate the maximum capabilities of the components of the oxygen transport system in sustained exercise.

Possible fragmentation routes were first obtained by controlled collision-activated dissociation (CAD) initiated by cone voltage fragmentation. Low energy CAD MS-MS analyses of the protonated molecules [M+H] confirmed the characteristic fingerprint patterns obtained by cone voltage fragmentation for all investigated triazine herbicides and also permitted differentiation of isomeric triazines.

The survival rate was > 95%. The following parameters were examined: appearance of fish and internal organs from a series of color photographs; fish condition index; hematocrit; somatic indices of liver, heart, spleen, and gonads; eye lens diameter; and plasma chloride. Liver, kidney, heart, spleen, gonad, gill, muscle, and gut tissues were also examined from paraffin sections for pathological changes. There were significant differences in testis somatic index, lens diameter, and plasma chloride between the two fish groups. No histopatbological changes were observed. Key words: marine fish, petroleum, chronic exposure, pathological changes

Subjects covered include effects of chronic exposure on physiology, histopathology and morphology of fish, gonad maturation, liver structure and function, invertebrates, and others. Refs.

There was no increase in blood lactate concentration, serially sampled during swimming by means of indwelling dorsal and ventral aortic catheters, at velocities as high as 93% of critical velocity of individuals. The data show that under these conditions the rate of production of lactate by white muscle, at less than critical velocities, is minimal or that the rate of elimination of lactate from white muscle is equal to its rate of utilization elsewhere. Immediately following fatigue blood lactate level increases rapidly. During the recovery period there appears to be a net uptake of lactate by the gills.

Male winter flounder were exposed to sediments contaminated with Venezuelan crude oil in 3 laboratory experiments of 4-5 months duration. 2. Oil exposure resulted in significant increases in liver weight. This was particularly evident in fish weighing less than 400 g. 3. The enlarged livers of the oil-exposed flounder had reduced concentrations of DNA, protein, Na+ and Zn2+, and increased concentrations of lipid and phospholipid. 4. The reduced DNA and Na+ concentrations suggested liver hypertrophy rather than hyperplasia. 5. The increased phospholipid concentrations suggested growth of membrane structures such as endoplasmic reticulum.

Total lipids, total phospholipids, lipid class and fatty acids have been studied in the livers of cod and winter flounder from the Northwest Atlantic following long-term exposure to crude petroleum. 2. The levels of free fatty acids and total phospholipids were elevated and triglycerides depleted significantly in the males and females of both species in the experimental groups. 3. The essential fatty acids of C20.5, C22.5 and C22.6 series were significantly altered in the oil-exposed animals. 4. These findings indicate that marine fish, following long-term exposure to crude petroleum, tend to (a) use up their stored energy of neutral lipids and (b) develop changes in membrane structure and function.

A combination of instrumental neutron activation analysis (INAA) and solvent extraction methods has been developed for the determination of EOX from the shrimp Pandalus borealis. Levels of EOX were evaluated for spatial trends for shrimp caught in several areas off the Labrador coast, off the coast of Nova Scotia, and off the coast of Maine. Muscle contained 1.09-6.05 ~tg EOC1/g tissue and 105-498 ~tg extractable organochlorine (EOC1)/g lipid; 0.0607-0.288 ~tg extractable organobromine (EOB)r/g tissue and 4.74-10.5 ~tg EOBr/g lipid; and 0.014-0.048 ~tg extractable organoiodine (EOI)/g tissue and 1.03-1.76 ~g EOI/g lipid, respectively. The levels of EOC1 in roe were 1.60-12.34 ~g/g tissue and 39.0-146 ~tg/g lipid. In roe, the EOBr levels were 0.707-1.03 ~tg/g tissue and 6.96-13.5 ~tg/g lipid; and EOI levels were 0.123-0.349 ~tg/g tissue and 1.42-4.11 ~tg/g lipid. The EOC1, EOBr, and EOI levels in roe increased noticeably from north to south along the coast of Labrador. Samples taken from the coast of Maine and from Canso Hole were typically higher in EOC1 levels than those taken from Labrador. The results for EOBr and EOI were in the same range as those from Labrador.

Two of the experiments were conducted in summer during the flounder's feeding period and 1 during winter when they do not feed. Mortalitles were observed in all experimental groups during summer, but were considerably greater in flounder exposed to oiled sediments than in those in un-oiled controls. Oiled sediments aged for a year remained toxic, although less so than freshly oiled sediments. No mortalities were observed during winter. Feeding rates were considerably reduced in flounder exposed to freshly oiled sediments. The aged oiled sediments had little or no effect on feeding rates. Control flounder showed greater increases in weight and condition than did exposed flounder, and flounder from aged oil revealed a greater increase in condition than did those exposed to fresh oil. Since winter flounder are obligatory residents of habitats which could become contaminated with oil, these results suggest that in the event of such an occurrence the winter flounder's ability to grow and store enough energy reserves to survive the winter could be reduced. It is suggested that the oil acts as a nonspecific stressor, which in conjunction with the high summer water temperatures and the effects of captivity resulted in significant mortality.
