Poisoning of livestock by toxic cyanobacteria was first reported in the 19th century, and throughout the 20th century cyanobacteria-related poisonings of livestock and wildlife in all continents have been described. Some mass mortality events involving unrelated fauna in prehistoric times have also been attributed to cyanotoxin poisoning; if correct, this serves as a reminder that toxic cyanoba...

poisons is arsenic, though the arsenic in question was generally not the pure chemical element itself but rather its oxide, As2O3 or diarsenic trioxide, otherwise known with equal inaccuracy as white arsenic. Indeed, since the most common form of this compound is actually composed of discrete As4O6 molecules, it should more properly be called tetraarsenic hexaoxide. For centuries proof of arsen...

Toxicology is the study of poisons and poisoning and has an ancient and venerable history. Although there have been numerous notorious poisonings throughout the ages and rather astute descriptions of toxic agents, the scientific study of toxicology did not commence until the 19th century. There was rapid development of analytical methods in the late 19th century and then an acceleration of both...

chronic arsenic poisoning (arsenicosis) is a global health risk, and it has been reported to improve the fitness, especially in altitudinal sickness in therapeutic dose. scarcity of systematic study on psychiatric co-morbidities in arsenicosis motivated us to conduct this research. the aim of this study was to estimate the co-morbid psychiatric disorders in patients with arsenicosis and to exam...

Background: Drinking water is the most important cause of poisoning in the world. Iran is one of the countries with arsenic-contaminated water upper limit of normal. In this study, we decided to determine the effects of chronic arsenic poisoning on demographic, clinical and laboratory features of people. Methods: This descriptive-sectional study carried out on all people resided in Shahidabad ...

A patient with severe arsenic poisoning that resulted in marked peripheral blood and bone marrow abnormalities, including megaloblastic erythropoiesis experienced many of the previously reported hematologic complications of arsenic poisoning: leukopenia, granulocytopenia, absolute eosinophilia, and profound anemia. In this study we report an ultrastructural and electron-probe analysis of the bo...

Arsenic poisoning is one of the more important causes of heavy metal poisoning in domestic animals. Two species--dogs and cattle--are intoxicated more frequently than other animals; yet sporadic instances of poisoning have been observed in cats, horses, and pigs. Cases observed by veterinary clinicians are either peracute, acute, or chronic intoxications. Frequently the initial and only indicat...

background: in the present times, arsenic poisoning contamination in the ground water has caused lots of health‑related problems in the village population residing in middle gangetic plain. in bihar, about 16 districts have been reported to be affected with arsenic poisoning. for the ground water and health assessment, simri village of buxar district was undertaken which is a flood plain region...

Lead poisoning existed and was already known in Antiquity but was forgotten, at least in the literature, until the end of the Middle Ages, where it was mentioned sporadically. In the 19th century this disease, which reached epidemic dimensions during the period of industrialization, was "rediscovered." Several comprehensive clinical articles appeared in the literature. The clinical picture deep...

Cardiovascular disease is the leading cause of mortality worldwide. Arsenic is a ubiquitous metalloid in the crust of the earth. Chronic arsenic poisoning is becoming an emerging epidemic in Asia. Epidemiological studies have shown that chronic arsenic poisoning through ingestion of arsenic-contaminated water is associated with various cardiovascular diseases in dose-response relationships. The...
