this study assesses the effect of major trace metals levels in wastewater discharges and sedimentfrom twenty four permanent and five semi-permanent wastewater drain outlets into the kuwait coast. theeffect of trace metals levels released from untreated wastewater discharges to euchelus asper, gastropod was also determined. results showed high trace metal levels in e. asper tissues, followed by ...

Trace metals play an important role in the regulation of primary productivity and phytoplankton community composition. Metal species directly affects biogeochemical cycling processes, transport, fate, bioavailability toxicity trace metals. Therefore, developing powerful methods for metal speciation analysis is very useful research a range fields, including chemical environmental analysis. Volta...

The intertidal copepod Tigriopus japonicus has been recognized as a potential model species for toxicity testing of marine pollutants. In last five years or so sequence information and expression pattern of several genes critical in detoxification, stress, growth and reproduction have been described from T. japonicus. A number of genes, especially those representing antioxidant and detoxificati...

As part of the casting process, foundries create sand molds and cores to hold the molten metal to specific dimensional tolerances. Although most of the waste foundry sands (WFSs) from this process are land filled, there is great interest in diverting them for use in agricultural and geotechnical applications. One potential limitation to their beneficial use is concern that the WFSs will leach h...

the toxicity of four potentially toxic trace elements (cu, ni, pb and zn) to annual atriplex (a.hortensis and a. rosea) was examined to determine if this plant showed sufficient tolerance to be used tophytoremediate soils polluted with these heavy metals. the soils, which contained up to (per kilogram) 501mg cu, 1674 mg ni, 1334 mg pb and 3588 mg of zn were sampled around metal-contaminated sit...

background and aims: although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (ag nps) and magnesium oxide nanoparticles (mgo nps) on the cardiomyocytes. materials and methods: cardiomyocy...

There has been much research into autism or autistic spectrum disorder (ASD) and room for considerable conjecture regarding the etiology of these disorders remain. ASD is marked by a complex interaction between environmental factors and genetic predisposition, including epistasis. This manuscript argues that changes in oxidative metabolism, thiamine homeostasis, heavy metal deposition and cellu...

The energy, mining and mineral processing industries are point sources of metal-contaminated waste water and carbon dioxide (CO2). Freshwater macroalgae from the genus Oedogonium can be grown in metal-contaminated waste water to generate biomass for bioenergy applications and concomitantly bioremediate metals. However, interactions between CO2 addition and algal growth, which can affect bioreme...
