The pH of estuarine waters
نویسنده
چکیده
The emf measurements for the TRIS buffer in seawater have been used to define buffer solutions that can be used to determine the pH on a free or total proton scale for estuarine waters. The pH is related to the stoichiometric dissociation constant (K*) of TRISH I-, the concentration of buffer (mTRrs) and salinity (5) by pH = pK* + (aS + bS2)mTRrs where a = -9.73 x 10e5 and b = 6.988 x 10-5. The values of pK* were fit to equations of the form

متن کاملBenthic infaunal community structuring in an acidified tropical estuarine system
BACKGROUND Recent studies suggest that increasing ocean acidification (OA) should have strong direct and indirect influences on marine invertebrates. While most theory and application for OA is based on relatively physically-stable oceanic ecological systems, less is known about the effects of acidification on nearshore and estuarine systems. Here, we investigated the structuring of a benthic i...
متن کاملSurvival of Vibrio cholerae and Escherichia coli in estuarine waters and sediments.
In in vitro estuarine water and sediment chambers, the survival of Vibrio cholerae and Escherichia coli was determined by plate counting and direct counting techniques. V. cholerae strains included environmental, clinical, and serotype O1 and non-O1 isolates, whereas E. coli strains included ATCC 25922 and a freshly cultured human isolate. Recovery of V. cholerae varied significantly with incub...
متن کاملDevelopment of an FIA system with amperometric detection for determination of bentazone in estuarine waters.
On the basis of its electrochemical behaviour a new flow-injection analysis (FIA) method with amperometric detection has been developed for quantification of the herbicide bentazone (BTZ) in estuarine waters. Standard solutions and samples (200 microL) were injected into a water carrier stream and both pH and ionic strength were automatically adjusted inside the manifold. Optimization of critic...

This study was carried out to investigate the occurrence of potentially pathogenic species of vibrio in sea water and estuarine environments of the Caspian Sea in the Golestan province of Iran. A total of 127 water samples from coastal waters as well as from river and estuaries were collected and analyzed by culture, during April and September 2001. Following prompt centrifugation, the resusp...
