Mercury (Hg) contamination is a global issue with implications for both ecosystem and human health. In this study, we use a new approach to link Hg exposure to health effects in spotted gar (Lepisosteus oculatus) from Caddo Lake (TX/LA). Previous field studies have reported elevated incidences of macrophage centers in liver, kidney, and spleen of fish with high concentrations of Hg. Macrophage ...

Despite widespread concern about the role of environmental contaminants in global amphibian declines, and evidence that post-metamorphic life stages contribute disproportionately to amphibian population dynamics, most studies in amphibian ecotoxicology focus on larval life stages. Studies that focus solely on early life stages may miss important effects of contaminant exposure, such as latent e...

Toxic metals polluting aquatic ecosystems are taken up by inhabitants and accumulate in the food web, affecting species at all trophic levels. It is therefore important to have good tools to assess the level of risk represented by toxic metals in the environment. Macrophytes are potential organisms for the identification of metal-responsive biomarkers but are still underrepresented in ecotoxico...

Owing to various industrial applications of mercury (Hg), its release into the environment at high concentration is becoming a great threat living organisms on global scale. Human exposure Hg greatly correlated with contamination in food chain through cereal crops and sea foods. Since non-essential component does not possess biological role exhibits carcinogenic genotoxic behaviour, biomonitori...

12 Previous studies have demonstrated that the commercial feed of aquacultured 13 fish contains trace amounts of toxic and essential metals which can accumulate 14 in tissues and finally be ingested by consumers. Recently rising temperatures, 15 associated to the global warming phenomenon, have been reported as a factor 16 to be taken into consideration in ecotoxicology, since temperature -depe...

Danu Rawa Taliwang is a large body of water that receives sources heavy metal pollution from human activities such as agriculture and mining. By using bioindicators fish, metals have been detected in the waters. The aim study was to determine content mercury (Hg) Rice Field Snail (Pila ampullacea) originating Lake enrich Ecotoxicology course material. special benefit protect consumers who consu...

Mercury (Hg) is a global pollutant that has received much attention due to its ability to persist within the environment and biota. Currently, most ecotoxicology studies euthanize animals to quantify the concentrations of Hg bioaccumulation. The development of nondestructive sampling techniques is a critical step for sustainable spatial and temporal monitoring of Hg accumulation because it elim...
