A 42-year-old man from Bhutan was admitted to the emergency department with a 5-day history of abdominal pain, nausea and vomiting. Enhanced abdominal CT scan was found negative, however laboratory tests showed hemolytic anemia and basophilic stippling which are often seen in lead and heavy metal poisoning. Additional tests revealed a high level of lead in blood and urine. The patient was admin...
Toxic metals are bioaccumulated by insectivorous mammals but few studies (none from Britain) have quantified residues in bats. We measured renal mercury (Hg), lead (Pb) and cadmium (Cd) concentrations in bats from south-west England to determine how they varied with species, sex, age, and over time, and if they were likely to cause adverse effects. Residues were generally highest in whiskered b...
Heavy metal pollution is propagating throughout the world with the enlargement of industrial activities. The elimination of heavy metal ions from industrial wastewaters has drawn much attention because of the hazardous effects of the heavy metal ions on different organisms. According to these facts, poly (2, 2, 3, 3- tetracyanocyclopropyl) phenyl acryl...
background: due to the increasing pollution of water resources, this study was carried out for evaluation of water quality pollution indices for monitoring of heavy metals (as, zn, pb and cu) contamination in ghahavand plain, hamadan province, western iran during spring and summer 2012. methods: totally, 20 ground water wells were chosen randomly. the samples were filtered (0.45 μm) and maintai...
background: iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (as, zn, pb and cu) contamination monitoring in toyserkan plain during spring and summer in 2012. methods: a total ...
Heavy metal ions are harmful for entomopathogenic fungi. Derivatives of starch dialdehyde such as dihydrazone (DHZ), dithiosemicarbazone (DTSC), and dioxime (DOX) were used to form water-insoluble complexes with heavy metal ions. This phenomenon thus provided protection of entomopathogenic fungus Paecilomyces farinosus from the toxic effects of heavy metal ions. The fungus growth and the sporul...
Global heavy metal pollution in the environment is a serious concern. The discharge of heavy metals from various anthropogenic and technogenic sources into the aquatic system poses a threat to the health of biota. Heavy metals persist in the environment since they cannot be degraded nor destroyed and finally reach the human through food chain. The major sources of lead pollution into waste wate...
Halomonas zincidurans strain B6(T) was isolated from a deep-sea heavy metal rich sediment from the South Atlantic Mid-Ocean Ridge. The strain showed significant resistance to heavy metals, especially to zinc. Here we describe the genome sequence and annotation, as well as the features, of the organism. The genome contains 3,325 protein-coding genes (2,848 with predicted functions), 61 tRNA gene...
Background: Due to environmental contamination in recent years, contamination of food chain by heavy metals is not far-fetched. The purpose of this study is to determine heavy metals in soybeans cultivated in Iran to monitor the food chemical contaminants. Methods: To assess metal contamination, four varieties (Sahar, Katool, Williams, and M7) of soybean cultivated in Iran, were collected. Met...
Background: Removal of heavy metal ions from contaminated systems by agricultural and fruit and vegetable processing waste materials is an innovative and auspicious technology .The current study was designed for utilization of bio-adsorption white hard eggshell, as less expensive and much frequently available food waste materials, due to prospective metal bio-sorption capacity to toxic heavy me...
