We report three paediatric cases of suspected heavy metal poisoning that presented with non-specific symptoms. Hair samples of the three patients were sent overseas for analysis; results showed abnormal levels of many elements, including some heavy metals. A diagnosis of heavy metal poisoning was made and chelation therapy was offered to each patient. Blood levels for some heavy metals were sub...

Objective- To evaluate the radiology application in diagnosis of heavy metal poisoning inbirds.Design- Descriptive study.Animals- In this article 4 suspected cases of heavy metal poisoning, including 3 African GreyParrots and a Sulfur Crested Cockatoo are described.Procedures- Presumptive diagnosis of heavy metal poisoning was made based on history andclinical signs including severe progressive...

Certain heavy metals such as mercury, lead, arsenic and cadmium are toxic even in reduced concentrations in blood. Their accumulation in the body causes serious illnesses. The most important heavy metals in human pathology are: mercury (Hg), cadmium (Cd), arsenic (As) and lead (Pb). The author mentions the heavy metal sources of poisoning, their toxicokinetics and toxicodynamics, clinical featu...

fifty-four drinking groundwater samples were collected in april 2010 from some districts of the dakahlyia governorate, egypt. the water samples were analyzed by atomic absorption spectrophotometer for iron, manganese, lead, nickel, chromium, zinc, copper, cobalt and cadmium concentrations. all samples but two were found suitable for drinking; from the water sample from aga district showed sligh...

Heavy metal poisonings in birds most commonly occur from ingestion of substances containing lead or zinc. Lead that is ingested can be absorbed through the gastrointestinal tract and then taken up by soft tissues and eventually by bone. Lead affects all major organs and can cause damage to the gastrointestinal tract, red blood cells, kidneys and liver. Clinical signs of heavy metal toxicosis ma...

Fluid catalytic cracking (FCC) is the main conversion process used in oil refineries. An X-ray microscopy method is used to show that metal poisoning and related structural changes in the zeolite active material lead to a non-uniform core–shell deactivation of FCC catalyst particles. The study links the detrimental effect of V and Ni poisoning with zeolite destruction and dealumination in a spa...

In this issue, Singh and colleagues[1] highlight the persistent international problem of heavy metal contamination, particularly lead, in traditional medicine products (TMPs). Certain TMPs from Asia, Latin America and the Middle East have all been associated with lead poisonings.[2] With travel and migration, contaminated TMPs have resulted in heavy metal intoxications in persons residing in co...
