Tetrapods include the only fully terrestrial vertebrates, but they also include many amphibious, aquatic and flying groups. They occupy the highest levels of the food chain on land and in aquatic environments. Tetrapod evolution has generated great interest, but the earliest phases of their history are poorly understood. Recent studies have questioned long-accepted hypotheses about the origin o...

Releases of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDFs) from industrial or thermal processes to the aquatic environment are considered small compared emissions air today. However, have occasionally released PCDD/PCDFs into local environments. . PCDD/PCDF formation releases were re-examined based on investigations conducted before introduction water quality regulations in Ja...

A large variety of aquatic animals was found to emit the potent greenhouse gas nitrous oxide when nitrate was present in the environment. The emission was ascribed to denitrification by ingested bacteria in the anoxic animal gut, and the exceptionally high N(2)O-to-N(2) production ratio suggested delayed induction of the last step of denitrification. Filter- and deposit-feeding animal species s...

Because of their unique physical, optical, and mechanical properties, nanomaterials hold great promise in improving on a wide variety of current technologies. Consequently, their use in research and consumer products is increasing rapidly, and contamination of the environment with various nanomaterials seems inevitable. Because surface waters receive pollutants and contaminants from many source...

Chemicals, including inorganic chemicals (nanoparticles, heavy metals, and other chemicals) and organic chemicals (pesticides, POPS, PBDEs, and other organic chemicals), are widely used in the world in recent 30 years to support the rapid development of industrialization and agriculture. The extensive use and discharge of these chemicals in these processes will produce wastewater containing a v...

Background & Aims of the Study: The presence of antibiotics in the environment, especially in aquatic environments is a major concern for health and the environment. The advanced oxidation process due to the ease of use, economical advantages and high performance have attracted a lot of attention. The purpose of this study was Evaluating of the photocatalytic role of zinc oxide on s...

Enzyme-linked immunosorbent assays (ELISAs) are important tools in aquatic toxicology and have become crucial in assessing exposure concentrations in the aquatic environment and acute physiological responses in exposed organisms. These assays utilize the inherent properties of antibodies to recognize and selectively bind a target molecule, while largely ignoring other molecules to provide semiq...

Aquatic toxicity studies with two different sizes of multi-walled carbon nanotubes (MWCNTs) and silver (Ag) nanoparticles were conducted on Rainbow trout fish Oncorhynchus mykiss, water flea Daphnia magna, and green algae Pseudokirchneriella subcapitata as model organisms. Author (1) along with co-authors conducted this research work at IIBAT as a part of PhD. The results of these studies indic...
