“…essentially the respiratory gas exchange surface) is similar in both morphotypes, but the branchial thickness, thus the diffusion distance, is lower in the 'short-fat' compared with the 'long-skinny' worms (Andersen et al, 2006;Hourdez and Lallier, 2007). Cytological alterations induced by heavy metal exposures have been observed in different types of epithelial tissues in several invertebrate taxa (Zaldibar et al, 2007;Cunha et al, 2008), and vertebrates (Pandey et al, 2008;Srivastava et al, 2009). However, the metal concentrations in the actively volcanic soil at Furnas are not particularly excessive, especially in comparison with those often encountered in mine-associated soils (Corp and Morgan, 1991), and lead to the conclusion that cations alone, even under the relatively acidic prevailing conditions, may not be the primary cause of the epidermal perturbations observed in the resident earthworms.…”

a b s t r a c tFor the first time, the structure, dimensions, and composition of the epidermis of an invasive earthworm species that has successfully colonized hostile conditions in actively volcanic soil on São Miguel (Azores) have been measured. Metal concentrations in actively volcanic (Furnas) and volcanically inactive (Fajã) soils were similar; however, Furnas soil was characterised by elevated temperature (10 1C differential), relative hypoxia, extremely high CO 2 tension, and accompanying acidity. The epidermis of earthworm's resident at Fajã was approximately twice the thickness of the epidermis of conspecifics resident in Furnas soil. Reference worms transferred to Furnas soil for 14 days experienced an epidermal thinning of approximately 51%. In comparison, when Furnas earthworms were transferred to mesocosms at the relatively benign Fajã site, their epidermal thickness increased by approximately 21% over 14 days. Earthworms resident in Furnas soil had higher goblet cell counts than the residents of volcanically inactive soil on a neighbouring island (S. Maria). Transferring worms from S. Maria to mesocosms at Furnas induced a significant increase in goblet cell counts. Clearly, the active volcanic environment at Furnas poses a multifactorial stress challenge to the epigeic A. gracilis colonizer.

“…The muscular tissue constitutes from one-third to one-half of the body mass of the average vertebrate and represents about 60% 0f the total fish body mass (Srivastava et al, 2009). Muscle tissue performs many of the vital functions such as locomotion through its direct connection with the skeletal system causing balanced swimming and helps to generate heat due to catabolic reactions that are associated with muscular activity and prevents movement of body by opposing forces.…”

ABSTRACTver the last decades, there has been a growing interest in studying the main problems that could be harmful to the River Nile system in Egypt. Attention was paid to one of the most important problems that face the River Nile, this is called River Nile transport project. So the main objective of the present study was to investigate the adverse effects that can result from spilled gasoline as petroleum product from various motor ships into the River Nile on one of the most important popular fishes in Egypt, Oreochromis niloticus to ascertain whether spilled gasoline into aquatic ecosystems can affect on the aquatic biota or not and to identify any potential public health risks that can be associated with dietary intake of such fish by histological and ultrastructural studies on its edible muscles. Levels of the growth hormone secreted by the pituitary gland which is essential to the development of skeletal muscles and growth rate was also examined. So, the fish were exposed to increasing concentrations of gasoline: 0 (control), 100, 200 and 500 mg/L for 30 days. Unexposed fish exhibited significantly higher levels of serum GH compared to that of tested fish. The GH levels decreased significantly with increasing gasoline concentrations. These data together indicate that Gasoline presents a hazardous substance for both the fish as well as the human consumers . Finally, the results revealed that the River Nile transport project can lead to serious harm to fish community that eventually become unsafe for human consumption. Therefore, this project must be carefully revised forbidden by health agencies.

“…Some chemicals as well as metals can lead to necrosis of hepatocyte cells (de Oliveira Ribeiro et al 2002;Sánchez-Chardi et al 2009), DNA fragmentation, and redox unbalance (Proskuryakov et al 2003). In the gills, some pathological alterations such as primary and secondary lamellae damage, fusion of adjacent lamellae, neoplasia, and aneurisms are characteristic of waterborne exposure to chemicals (Liu et al 2010;Srivastava et al 2009). Incidence of lesions in target organs, evidences of neurotoxicity, and macromolecules damage associated with bioaccumulation of toxic metals and PAHs indicated the impact on fish health related to low water quality of the five reservoirs.…”

The Iguaçu River, located at the Southern part of Brazil, has a great socioeconomic and environmental importance due to its high endemic fish fauna and its potential to generate hydroelectric power. However, Iguaçu River suffers intense discharge of pollutants in the origin of the river. In a previous report, the local environmental agency described water quality to improve along the river course. However, no study with integrated evaluation of chemical analysis and biological responses has been reported so far for the Iguaçu River. In the current study, three different Brazilian fish species (Astyanax bifasciatus, Chrenicicla iguassuensis, and Geophagus brasiliensis) were captured in the five cascading reservoirs of Iguaçu River for a multi-biomarker study. Chemical analysis in water, sediment, and muscle indicated high levels of bioavailable metals in all reservoirs. Polycyclic aromatic hydrocarbons (PAHs) were detected in the bile of the three fish species. Integration of the data through a FA/PCA analysis demonstrated the poorest environmental quality of the reservoir farthest from river's source, which is the opposite of what has been reported by the environmental agency. The presence of hazardous chemicals in the five reservoirs of Iguaçu River, their bioaccumulation in the muscle of fish, and the biological responses showed the impacts of human activities to this area and did not confirm a gradient of pollution between the five reservoirs, from the source toward Iguaçu River's mouth. Therefore, diffuse source of pollutants present along the river course are increasing the risk of exposure to biota and human populations.
