“…The presence of linear alkylbenzenes has been previously reported not only in sediments under the influence of the sewage outfall at Santos Bay , but also in sediments affected by the port activities in the Santos Estuarine System . Another study reported the accumulation of linear alkylbenzenes in the soft tissues of shellfish transplanted to the Bay of Santos . In the present study, the concentrations of linear alkylbenzene sulfonate in interstitial water from both S1 and S2 were well above the detergent toxicity threshold of sea urchin embryos , and the levels found exceed international guidelines.…”

Domestic sewage is a major problem in highly urbanized coastal areas worldwide. In the present study, toxicity identification evaluation (TIE) phases I and II were applied to sediment interstitial water from 2 locations along the São Paulo coast in southeastern Brazil: the sewage outfalls from the city of Santos, a densely urbanized area, and the city of Bertioga, a less urbanized area. An adapted microscale sea urchin embryo-larval development bioassay was employed. Phase TIE-I manipulations were 1) ethylenediamine tetraacetic acid (EDTA) addition, 2) aeration at modified pH, 3) C18 solid-phase extraction (SPE), and 4) addition of Na S O . The results of the Santos TIE-I indicated toxicity by sulfides and substances with affinity to C18 resin. In Bertioga, toxicity was the result of NH , metals, and arsenic, as well as substances with affinity to C18 resin. Phase TIE-II aimed to specify the causes of toxicity by testing the toxicity of eluates of the sublation and C18 SPE manipulation. The results reinforced the role of both surfactants and nonpolar compounds as causative agents of toxicity in both Santos and Bertioga. Chemical analyses of sediment interstitial water or whole sediment ruled out the influence of polycyclic aromatic hydrocarbons (PAHs) or polychlorinated biphenyls (PCBs) in the toxicity of both sampling sites. Other hydrophobic substances may play a role in the toxicity of Santos and Bertioga effluents. Efforts to remove such substances from sanitary effluents must be prioritized.

“…Oxidative stress occurs when the equilibrium between ROS production and the antioxidant defenses is lost. ROS can be important mediators of damage to cell structures, including lipids and membranes, proteins and nucleic acids, that can seriously alter the cell membranes and other structures such as proteins, lipids, lipoproteins, and deoxyribonucleic acid (DNA), which lead to different pathologic processes, and fish diseases [8]. The first line of defense against oxidative stress is SOD, CAT and SOD catalyzes the superoxide anion radical (O 2 ) dismutation into hydrogen peroxide (H 2 O 2 ) by reduction.…”

Recently, the aquatic organisms are used as indicators of trace metals pollution. Heavy metal concentrations are extremely variable in various marine and fresh water organisms depending on the geochemical background, the level of pollution in a given area and fish activity [3]. Bioaccumulation of heavy metals in fish may critically influence the growth rate, physiological and biochemical status, and consequently the meat quality of fish. Moreover, it has been observed that through biological amplification, some aquatic organisms may concentrate metals present with low amounts in the environment to levels that exceed standards, which are harmful to organisms. Fish likewise other aquatic organisms, are greatly affected with chemical pollutants present in the ecosystem. It is recommended that the developed histopathological changes in fish can be used as biondicators for environmental pollution [4]. AbstractLake Burullus represents an economically important brackishwater coastal lagoon in Egypt, due to its rich fishery resources. In addition to the remains of agricultural wastes, the lake is exposed to many kinds of chemical and biological pollutants that are disposed into it. So, the study was carried out on three sectors in the lake. Western sector of the lake where agricultural drainage was discharged, eastern sector where agricultural and industrial effluents was entered, and middle sector where the least pollution was occurred among them. The present study was controlled to assess the harmful effects of heavy metals on the biochemical and antioxidant defense system in Nile tilapia collected from three sectors. The studied heavy metals in gills, liver, and muscles of the Nile tilapia (Oreochromis niloticus) collected from the eastern and western sectors of the lake was much higher than that of fish collected from middle sector. Biochemical profile and antioxidant defense system of Nile tilapia were significantly (P<0.05) higher in fish collected from western and eastern sectors during summer and winter seasons compared to the middle sector. The results obtained from the present study also revealed that the meat quality of the collected fish from middle sector was more superior to those of fish collected from the eastern and western sectors of the lake. The study also indicates that the alterations in the biochemistry profile and antioxidant defense system of Nile tilapia can be used as biomarkers of metal pollution for monitoring aquatic life.

“…This species is well accepted as a biological model for experimental studies mostly because of its high tolerance to environmental changes, easy access for collecting, and known biology (Ferreira and Magalhães, 2010). It is also a good bioindicator, with their gills, digestive gland and hemolymph as well-known targets for xenobiotics, frequently used for analysis of bioaccumulation and effects of pollutants (Najimi et al, 1997;Ferreira et al, 2004;De Almeida et al, 2007;Pereira et al, 2011). Mussels (± 6.0 cm) were purchased from a cultivation system at Lagoinha Beach (Ubatuba, São Paulo), cleaned of epifauna and acclimatized for 5 days in a maintenance tank (1000L).…”
