Statistical analyses and risk assessment of potentially toxic metals (PTMS) in children’s toys

Toxic metals in children's toys and jewelry: coupling bioaccessibility with risk assessment.

A total of 45 children's toys and jewelry were tested for total and bioaccessible metal concentrations. Total As, Cd, Sb, Cr, Ni, and Pb concentrations were 0.22-19, 0.01-139, 0.1-189, 0.06-846, 0.14-2894 and 0.08-860,000 mg kg(-1). Metallic products had the highest concentrations, with 3-7 out of 13 samples exceeding the European Union safety limit for Cd, Pb, Cr, or Ni. However, assessment ba...

Human health risk assessment of toxic metals

Toxic Toys

principal investigator for the team. His collaborators were Jean-Pierre Kinet, a professor of pathology at Harvard Medical School who first cloned the gene for the IgE receptor in 1986, and Scott Garman, a postdoctoral fellow in the Northwestern Department of Biochemistry, Molecular Biology, and Cell Biology. About 50 million people in the United States have some form of allergy. Many allergies...

Study of contamination, sources and health risk of potentially toxic elements in dusts of Tehran’s elementary schools

Concerns about dust contamination with potentially toxic elements are especially important in environments such as schools (particularly elementary schools) because children are more vulnerable to contaminants than adults. Therefore, due to the diversity of air pollution sources in Tehran, the present study was conducted to determine the severity of pollution, origin and health risk assessment ...

The accumulation of potentially-toxic metals by grazing ruminants.

The main factors affecting the accumulation of potentially-toxic metals (PTM) by grazing animals are the presence of the metal, its concentration in herbage and at the soil surface, and the duration of exposure to the contaminated pasture and soil. In addition, the elapsed time between the contamination of the pasture and grazing, the quantity of soil ingested together with herbage, the mechani...
