Target Organ Toxicity in Marine and Freshwater Teleosts: Organs
Format: PDF / Kindle (mobi) / ePub
Addressing the numerous gaps in current information, Target Organ Toxicology in Marine and Freshwater Teleosts is an essential resource for researchers and professionals in aquatic toxicology and environmental risk assessment. All the chapters are written by researchers who are internationally recognised for their work in mechanistic aspects of aquatic toxicology. Each chapter focuses on a specific target organ or physiological system and describes how various agents disrupt the normal physiological system and processes. This volume is devoted to specific organs with coverage of the gill, kidney, skin, liver and gut. The companion volume, Systems, provides coverage of toxic effects in the central nervous, immune, neurobehavioural and reproductive systems as well as describing general mechanisms of toxicity.
distribution of blood. The actual cellular structure of the branchial blood vessels (i.e. pillar cells endothelium and smooth muscle of afferent and efferent vessels) appears very resistant. The fourteen different lesion types are summarized in Mallatt’s very useful diagram of a freshwater trout gill (reproduced as Figure 1.8 here), numbered from 1 (most often reported) to 14 (least often reported). Unfortunately, both at the time of Mallatt’s review (in which only 15 percent of the studies were

Myofibrils are located in the mesangium layer, and their ability to contract may contribute to regulation of the effective filtration area and/or change the blood flow pattern through the glomerulus (Yokota et al., 1985; Dantzler, 1989). Furthermore, an increase in the thickness of this layer possibly reduces the capillary lumen and thereby the endothelial surface area available for filtration (de Ruiter, 1980). Phagocytic capacity of mesangial cells have

The percentage composition of the major components of surface mucus from a sample of six different species of marine fish is also given in Table 3.1. These components were generally similar, but sialic acid seemed less important in these species than in
