Cochrane reviews on the benefits/risks of fluoride toothpastes
Abstract This concise review presents two Cochrane Reviews undertaken to determine: (1) the relative effectiveness of fluoride toothpastes of different concentrations in preventing dental caries in children and adolescents; and (2) the relationship between the use of topical fluorides in young children and their risk of developing dental fluorosis. To determine the relative effectiveness of […]

15 conservation issues to watch
Excerpts: … “Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental,” the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the […]

Application, chemistry, and environmental implications of contaminant-immobilization amendments on agricultural soil and water quality
Abstract Contaminants such as nitrogen (N), phosphorus (P), dissolved organic carbon (DOC), arsenic (As), heavy metals, and infectious pathogens are often associated with agricultural systems. Various soil and water remediation techniques including the use of chemical amendments have been employed to reduce the risks associated with these contaminants. This paper reviews the use of chemical […]

Fluoride in water lowers IQ levels: report
Exposure to fluoride may lower children’s intelligence, says a study published in Environmental Health Perspectives, a publication of the National Institute of Environmental Health Sciences. Fluoride is added to 70 percent of U.S. public drinking water supplies. For the study, 512 children aged 8-13 years in two Chinese villages were tested – Wamaio with an […]

Do We Really Need Fluoride In Water?
Have you ever wondered why we need to have fluoride in drinking water when there is already fluoride in our toothpaste? The October 2010 issue of the journal of the American Dental Association has confirmed that infants fed with formula milk prepared from fluoridated water run a greater risk of fluorosis (mottling and discolouration of […]

Normal children’s toothpaste not strong enough to prevent tooth decay, study finds
Parents should use toothpaste with stronger concentrations of fluoride to prevent tooth decay in their children, a new report says. Researchers found that toothpaste that contained fluoride concentrations less than 1,000 parts per million were only as effective at preventing tooth decay as non-fluoride products. The study, carried out by the Cochrane Oral Health Group, […]

Best Fluoride Levels Determined for Children’s Toothpastes
Everyone who has ever seen a toothpaste commercial knows that fluoride is the ingredient that helps fight tooth decay, but a new review has determined exactly how much fluoride is best in toothpastes for children. For optimal prevention of cavities in children over age 6, toothpastes should contain at least 1,000 parts per million of […]

Site preferences of fluoride guest ions in the calcium silicate phases of Portland cement from 29Si{19F} CP-REDOR NMR spectroscopy.
Abstract A reduction in CO(2) emission from Portland cement production can be achieved by energy savings associated with a lowering of the temperature at which the high temperature alite (Ca(3)SiO(5)) and belite (Ca(2)SiO(4)) silicates form. This can be accomplished by fluoride mineralization where a small amount of fluorine (e.g., CaF(2)) is added to the raw […]

Lithium in water ‘curbs suicide’
Researchers examined levels of lithium in drinking water and suicide rates in the prefecture of Oita, which has a population of more than one million. The suicide rate was significantly lower in those areas with the highest levels of the element, they wrote in the British Journal of Psychiatry. High doses of lithium are already […]

Environmental hazards and health risk of common liquid perfluoro-n-alkanes, potent greenhouse gases
Abstract This article aimed at introducing the main physical properties and commercial/industrial uses of common liquid perfluoro-n-alkanes (including perfluoropentane, perfluorohexane, perfluoroheptane, perfluorooctane, and perfluorononane) and the environment and health hazards posed by their toxic decomposition products (especially in hydrogen fluoride and perfluoroisobutylene) because these perfluorocompounds are potent greenhouse gases, which have been blanketed into the […]
