Protecting Children From Overexposure To Lead In Candy And Protecting Children By Lowering The Blood Lead “Level Of Concern” Standard, Bryan Wagner, Colleen C. Hughes, Robert Sobsey
Nevada Journal of Public Health
The American Public Health Association: Recognizing that in April 2004, the Orange County Register in an investigative report, published for the first time information that the state of California had been testing for lead in candies for decades but had not informed the public about the high lead levels in many candies, candy wrappers and seasonings (sold as a snack item and consumed as candy) imported from Mexico, the Philippines and other countries.

Historical Diversification Of Montane Herpetofauna Within And Between The Sierras Of Mexico, Robert William Bryson Jr.

The Mexican highlands consist of four major mountain ranges spanning most of mainland Mexico. The evolutionary history of the Mexican highlands has been shaped by various geological and climatic events over the past several million years. The relative impacts of these historical events on diversification in montane taxa, however, remains uncertain. I used mitochondrial DNA data from three widely distributed species complexes of lizards as a model system to exemplify the potential roles of Neogene mountain formation and Quaternary climate change on timing and tempo of diversification across the Mexican highlands. My results suggested strong geographic partitioning of genetic variation …
