Carbon Dioxide is Not a “Pollutant”; Increases Promote Plant Growth

“The promoters of global warming fear ignore the great agricultural benefits of increased CO2 in the atmosphere.  Increased CO2 promotes plant growth and has generated billions of dollars of increased agricultural production in the last 50 years.” click here and here

Pharmaceuticals and Personal Care Products (PPCPs) in Advanced Treated Drinking Water, Taihu Lake, China

Lin T, Yu S, Chen W. Occurrence, removal and risk assessment of pharmaceutical and personal care products (PPCPs) in an advanced drinking water treatment plant (ADWTP) around Taihu Lake in China. Chemosphere. 2016 Mar 1;152:1-9. doi: 10.1016/j.chemosphere.2016.02.109.

The occurrence and removal of 39 selected pharmaceutical and personal care products (PPCPs) were investigated in an advanced drinking water treatment plant (ADWTP) around Taihu Lake. Fourteen of 39 targeted pharmaceuticals were detected in the raw water. After a series of purification processes, only indomethacin, caffeine and sulfamethoxazole were found in effluent, albeit at concentrations less than 2 ng L-1. The results of principal component analysis suggested that three main purification processes, oxidation, coagulation combined with sedimentation and filtration combined with bio-degradation, influenced the removal performance of PPCPs. The ecotoxicological and human health risk assessment confirmed that drugs detected in effluent posed no potential toxicity and also suggested that two PPCPs (roxithromycin and sulfamethoxazole), especially sulfamethoxazole, should be seriously considered as candidates for regulatory monitoring and prioritization. Finally, the correlation between removal efficiency and risk quotient indicated that uniform removal efficiency for all PPCPs may not reflect an equal risk control in the ADWTP.

When Scientists Behave Poorly Productive Exchange of Ideas Stops

“In a recent set of Tweets …….Dr. Michael Mann of ‘hockey stick’ infamy, accused Tim Ball and Anthony Watts of supporting the theories of Immanuel Velikovsky. He based his claim on an article about scientific elitism [Ball] wrote that Anthony Watts kindly published on his web site. Mann’s accusation is completely false and indicates he either failed to read the article or if he did, failed to understand its purpose.” click here for full post.
