Ampicillin hydrochloride (C16H19N3O4S•HCl, CAS 69-52-3, pharmaceutical EU standard grade) and clarithromycin (C38H69NO13, CAS 81103-11-9, pharmaceutical EU standard grade) were purchased from Sigma-Aldrich (Germancy). Stock solutions of AMP (50 mg L -1 ) and CLA (50 mg L -1 ) were prepared with deionized water immediately prior to toxicity tests. The DOC employed in the tests was Suwannee River natural organic matter (SRNOM, 2R101N), purchased from the International Humic Substances Society. The DOC stock (318.52 mg L -1 ) was prepared in Milli-Q water and preserved at 4 °C.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
