Ms. Hillary Clinton Less than Honest About Benghazi Threatening Security

“Yesterday’s lawyer-lingo evasions don’t matter any more, because it was all B.S. anyway. When inspectors general discovered hard proof of then-classified material flowing through ClintonMail.com, they referred the matter to the Justice Department… and warned that future public releases of Clinton’s email could be peppered with enough secret information to threaten national security.” click here for article.

Association of Urine Fluoride with Dental Fluorosis; Mexico

Jarquín-Yañez L, de Jesús Mejía-Saavedra J, Molina-Frechero N, Gaona E, Rocha-Amador DO, López-Guzmán OD, Bologna-Molina R. Association between urine fluoride and dental fluorosis as a toxicity factor in a rural community in the state of San Luis Potosi. TheScientificWorldJournal. 2015;2015:647184. doi: 10.1155/2015/647184.

OBJECTIVE: The aim of this study is to investigate urine fluoride concentration as a toxicity factor in a rural community in the state of San Luis Potosi, Mexico.

MATERIALS AND METHODS: A sample of 111 children exposed to high concentrations of fluoride in drinking water (4.13 mg/L) was evaluated. Fluoride exposure was determined by measuring urine fluoride concentration using the potentiometric method with an ion selective electrode. The diagnosis of dental fluorosis was performed by clinical examination, and the severity of damage was determined using Dean’s index and the Thylstrup-Fejerskov (TF) index.

RESULTS: The range of exposure in the study population, evaluated through the fluoride content in urine, was 1.1 to 5.9 mg/L, with a mean of 3.14±1.09 mg/L. Dental fluorosis was present in all subjects, of which 95% had severe cases. Higher urine fluoride levels and greater degrees of severity occurred in older children.

CONCLUSIONS: The results show that dental fluorosis was determined by the presence of fluoride exposure finding a high positive correlation between the severity of fluorosis and urine fluoride concentration and the years of exposure suggested a cumulative effect.

USEPA Administrator Under Fire for Mismanagement

In light of today’s employment laws a situation such as this must not be taken lightly. Draw your own conclusions….

“The EPA inspector general found that agency employee Peter Jutro “engaged in offensive and inappropriate behavior toward at least 16 women, most of whom were EPA co-workers.” The IG report also found that very senior EPA officials “were made aware of many of these actions and yet did nothing.” Instead of reprimanding Jutro, he was promoted to be Assistant Administrator for the EPA’s Office of Homeland Security where he “engaged in such behavior toward an additional six women,” the IG report said.” Click here for article.

Naturally Occurring Radionuclides to Determine Distribution System Water Age

Waples JT, Bordewyk JK, Knesting KM, Orlandini KA. Using naturally occurring radionuclides to determine drinking water age in a community water system. Environmental science and technology. 2015 Jul 22.

Drinking water quality in a community water system is closely linked to the age of water from initial treatment to time of delivery. However, water age is difficult to measure with conventional chemical tracers; particularly in stagnant water, where the relationship between disinfectant decay, microbial growth, and water age is poorly understood. Using radionuclides that were naturally present in source water, we found that measured activity ratios of 90Y/90Sr and 234Th/238U in discrete drinking water samples of known age accurately estimated water age up to 9 days old (σest: ± 3.8 hours, P < 0.0001, r2 = 0.998, n =11) and 25 days old (σest: ± 13.3 hours, P < 0.0001, r2 = 0.996, n =12), respectively. Moreover, 90Y-derived water ages in a community water system (6.8 × 104 m3 d-1 capacity) were generally consistent with water ages derived from an extended period simulation model. Radionuclides differ from conventional chemical tracers in that they are ubiquitous in distribution mains and connected premise plumbing. The ability to measure both water age and an analyte (e.g., chemical or microbe) in any water sample at any time allows for new insight into factors that control drinking water quality.
