in this study, the effect of some toxic organic chemicals on mogan lake has been investigatedusing the aquatox model. the unique property of the model includes the sub ecotoxicological modelwhen compared to the other water quality models. the ecosystem model aquatox, which is one of the fewgeneral ecological risk models that represents the combined environmental repercussions and effects of tox...
Over the past 3 decades, in a series of studies on some of the most extensively studied toxic chemicals and pollutants, scientists have found that the amount of toxic chemical linked with the development of a disease or death-which is central to determining "safe" or "hazardous" levels-is proportionately greater at the lowest dose or levels of exposure. These results, which are contrary to the ...
Network Analysis of Toxic Chemicals and Symptoms: Implications for Designing First-Responder Systems
The rapid and accurate identification of toxic chemicals is critical for saving lives in emergency situations. However, first-responder systems such as WISER typically require a large number of inputs before a chemical can be identified. To address this problem, we used networks to visualize and analyze the complex relationship between toxic chemicals and their symptoms. The results explain why...
The toxic action of environmental chemicals on reproduction and the toxiclike effects of ovarian hormones have been shown by numerous investigators. Some toxic effects of environmental chemicals on reproduction are through their action on hormonal secretion. Such effects on the endocrine system could provide additional approaches to investigations of toxicity of compounds. A better understandin...
