Eau de mer Un article de Wikipédia, l'encyclopédie libre. Salinité moyenne des océans[1], exprimée en PSU, c'est-à-dire en grammes de sel par kilogramme d'eau de mer. Volume[modifier | modifier le code] Les océans et mers occupent un volume estimé à 1 340 millions de km³, ce qui représente 97,4 % des réserves d'eau présentes à la surface de la Terre. Origine du sel de l'eau de mer[modifier | modifier le code] La théorie de Halley est en grande partie correcte. La salinité moyenne des océans est stable depuis plusieurs milliards d'années, le plus probablement grâce à un processus tectonique et chimique qui enlève autant de sel qu'il en arrive par les rivières. Caractéristiques[modifier | modifier le code] Composition[modifier | modifier le code] L'eau de mer est composée d'eau et de sels, ainsi que de diverses substances en faible quantité. La salinité est un des paramètres les plus importants de l'eau de mer, et désigne la teneur en sels dissous. Principaux composants de l'eau de mer

DSpace Principal untitled EUROPE 10/02/99 Opinion on the safety of boric acid in medicinal products adopted on 10 February 1999 Question The Committee is asked the following three questions: Does the safety profile of boric acid support its use in parenteral medications intended for neonates ? Should the current contraindication for boric acid in the guideline on the excipients in the label and package leaflet of medicinal products for human use remain in its current form ? Does the safety profile and clinical experience of boric acid support the establishment of threshold dose levels below which the contraindication should not be labelled ? Context of the question The question is asked in the frame of a "Guideline on the excipients in the label and package leaflet of medicinal products for human use" approved by the Pharmaceutical Committee which became applicable from 1st September 1997. Assessment The Scientific Committee of Medicinal Products and Medical Devices is of the opinion that insufficient information was provided to address fully the questions asked.
