Peripheral Metal Complexes: Chlorophyll “Isomers” with Magnesium Bound to the Ring E ß-Keto Ester System
No full textPeripheral magnesium complexes of methyl pheophorbides a and b, bacteriomethyl pheophorbide a, bacteriopheophytin
a, and protopheophytin a have been prepared and characterized by UV-vis, IR, ‘H NMR, and luminescence spectroscopy.
In these compounds, Mg is bound to the peripheral p-keto ester system present in most chlorophylls rather than to the
central tetrapyrrole cavity as in the chlorophyll proper. The ligand exchange reactions at Mg have been characterized, and the
equilibrium between the peripheral complexes and their free ligands has been studied over the concentration range lo-’-
M. AGO for complex formation has been determined by ’H NMR spectroscopy

No full textFollowing a request from the Commission, the Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) reviewed the report prepared by the European Commission Joint Research Centre on “Proposed EU minimum quality requirements for water reuse in agricultural irrigation and aquifer recharge". The SCHEER concludes that, while the methodology chosen is appropriate and the report considers many important elements, the document is deficient in key details. The SCHEER recommends that the description of the methodology be extended and detailed guidance be provided on how minimum quality requirements should be derived. The SCHEER is of the opinion that, in its current form, the minimum quality requirements proposed provide insufficient protection both to environmental and human health

Scientific Advice on Guidance Document n°27: Technical Guidance for Deriving Environmental Quality Standards
No full textFollowing a request from the Commission, the Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) reviewed the Guidance Document No. 27:
‘Technical Guidance for Deriving Environmental Quality Standards’ prepared by a collaborative framework (the Common Implementation Strategy) for the Water Framework
Directive.
The SCHEER concludes that the overall scientific quality of the proposed changes is an improvement to the earlier 2011 version. The SCHEER has a number of comments where more practical guidance can be provided or where the current state of knowledge is still insufficient or where it is not being fully utilised
