Mr. Arnold Schwartznegger does not know of what he speaks

Mr. Schwartznegger is seriously misinformed on climate as well as the Indiana religious freedom law. Perhaps he is a “democrat denier.”

“During his time as governor of California, Arnold Schwarzenegger championed issues — like environmental conservation and stem cell research — that are often associated with a Democratic agenda. The Republican took another perceived dip in the liberal pond earlier this month with his Washington Post op-ed slamming the “religious freedom” law pushed by Indiana’s Gov. Mike Pence, another Republican.” here

Now its Mr. John McCain’s Turn to do Some ‘Splainin’

What do Mr. McCain and Ms. Hillary Clinton have in common? The both have ‘splainin’ to do. (click here)

“Three years’ of IRS e-mail evidence continues to build against the federal government. The most interesting and possibly disturbing piece of information deals with the fact that Republican Senator McCain and Democrat Senator Carl Levin were both aware of the targeting eleven days before Lerner’s public admission of “inappropriate” actions.” click here

Organic Contaminants in Chalk Groundwater, England and France

Lapworth DJ, Baran N, Stuart ME, Manamsa K, Talbot J. Persistent and emerging micro-organic contaminants in Chalk groundwater of England and France. Environmental pollution. 2015 Apr 13. pii: S0269-7491(15)00106-2. doi: 10.1016/j.envpol.2015.02.030.

The Chalk aquifer of Northern Europe is an internationally important source of drinking water and sustains baseflow for surface water ecosystems. The areal distribution of microorganic (MO) contaminants, particularly non-regulated emerging MOs, in this aquifer is poorly understood. This study presents results from a reconnaissance survey of MOs in Chalk groundwater, including pharmaceuticals, personal care products and pesticides and their transformation products, conducted across the major Chalk aquifers of England and France. Data from a total of 345 sites collected during 2011 were included in this study to provide a representative baseline assessment of MO occurrence in groundwater. A suite of 42 MOs were analysed for at each site including industrial compounds (n=16), pesticides (n=14) and pharmaceuticals, personal care and lifestyle products (n=12). Occurrence data is evaluated in relation to land use, aquifer exposure, well depth and depth to groundwater to provide an understanding of vulnerable groundwater settings.

Sea Level Rise in Florida not Catestrophic

Mr. Barack Obama is raising alarm about sea level rise in Florida (here). He seems to be overlooking some very important real-world measurements. 

8723170

The mean sea level trend is 2.39 millimeters/year with a 95% confidence
interval of +/- 0.43 mm/yr based on monthly mean sea level data from
1931 to 1981 which is equivalent to a change of 0.78 feet in 100 years.

Even if the underlying assumptions behind historical reconstructions of sea level are accepted there has been no catastrophic changes in sea level for several thousand years. One must wonder what planet Mr. Obama is talking about. happy-bouncing-smilie

An Improved Method for Halogen-Specific TOX

Kristiana I, McDonald S, Tan J, Joll C, Heitz A. Analysis of halogen-specific TOX revisited: Method improvement and application. Talanta. 2015 Jul 1;139:104-10. doi: 10.1016/j.talanta.2015.02.029.

A method was optimised and evaluated for the analysis of total organic halogen (TOX) in drinking water samples. It involved adsorption of organic halogen onto activated carbon, followed by combustion of the activated carbon and adsorbed material, absorption of the resulting hydrogen halide gases in an absorbing solution, and analysis of halide ions in the solution using an on-line ion chromatograph. Careful optimisation and validation of the method resulted in significant improvements compared to previously reported methods. Method detection limits were 5µgL(-1) for TOCl (as Cl(-)), 2µgL(-1) for TOBr (as Br(-)), and 2µgL(-1) for TOI (as I(-)). Interferences with TOI measurement occurred when iodide or iodate was present in the sample at concentrations at or above 100µgL(-1) and 500µgL(-1), respectively. In general, excellent method recoveries were determined for a wide range of model compounds. The method was used to investigate the formation of halogen-specific TOX through a water treatment plant and in laboratory-scale disinfection experiments. Up to 70% of bromide in the water was converted to TOBr following disinfection at the plant. In the disinfection experiments, TOI was preferentially formed in chloraminated samples, and trihalomethanes only constituted a small fraction (≤20%) of TOX, highlighting the significant proportion of halogenated organic DBPs that are not measured regularly. This is the first report of a comprehensive assessment of the key parameters influencing the efficiency and reliability of the analysis of halogen-specific TOX in drinking water with demonstration of its applications.
