The pH of estuarine waters
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...
متن کاملPfiesteria in Estuarine Waters: The Question of Health Risks
The Question of Health Risks The conclusion of Morris et al. (2006) that “Exposure to Pfiesteria Species in Estuarine Waters Is Not a Risk Factor for Illness” is unsupported because a) a description of Pfiesteria-related fish kills in the Chesapeake estuaries during 1999–2002 was omitted; b) quantitative data on Pfiesteria were not collected; c) data on visual contrast sensitivity (VCS) were co...
متن کاملKinetics of trace element uptake and release by particles in estuarine waters: effects of pH, salinity, and particle loading.
The uptake and release of 109Cd, 51Cr, 60Co, 59Fe, 54Mn, and 65Zn were studied using end-member waters and particles from Port Jackson estuary, Australia. The kinetics of adsorption and desorption were studied as a function of suspended particulate matter (SPM) loading and salinity. Batch experiments showed that the position and slope of the pH edges are dependent on the metal and on the salini...
متن کاملStability of human enteroviruses in estuarine and marine waters.
Studies of the effects of temperature and salinity on the survival of three enteric viruses (poliomyelitis type 1, echovirus-6, and coxsackievirus B-5) under controlled laboratory conditions and in situ indicate that temperature rather than salinity is the critical factor affecting their stability, in that the higher the temperature the more rapid was the loss of viral infectivity. In the labor...
متن کاملAlgae and cyanobacteria in coastal and estuarine waters
In coastal and estuarine waters, algae range from single-celled forms to the seaweeds. Cyanobacteria are organisms with some characteristics of bacteria and some of algae. They are similar in size to the unicellular algae and, unlike other bacteria, contain blue-green or green pigments and are able to perform photosynthesis; thus, they are also termed blue-green algae. Algal blooms in the sea h...
