Eutrophication monitoring

The similarities between the parameters are obvious. The only thing that remains to be assmed is that the methods used for the measurement of these parameters will give the same results. Only in this way can a serious duplication of efforts be avoided. True to its principles, OSPAR has a number of clear monitoring guidelines to assist in eutrophication monitoring and assessment. These are ...

The technical approach to calculate critical loads used in this research was similar to that described earlier (Posch et al., 1999 Bashkin et al., 2001a). Different biogeochemical data were used for the calculation and mapping of critical loads for acid forming and eutrophication compounds (SO2, NO ). These data were monitored... 

For non-metallic constituents, several systems exist especially for nutrients monitoring, considering their importance in the eutrophication phenomenon. The on-line measurement of some nitrogen compounds (nitrate and ammo-... 

With a leachate from a coal tar site, each day 2 kg of anthracene are introduced continuously into the epilimnion of a eutrophic lake. The lake is stratified between April and November. As an employee of the state water authority you are asked to monitor the anthracene concentration in the epilimnion of this lake. In order to get an idea of how sensitive your analytical technique has to be, you wonder what anthracene... 

Fortunately, we are beginning to actually detect measurable improvements in the water quality of some estuaries due to scientifically based nutrient reductions and extensive longterm monitoring studies. For example, the Patuxent River in Maryland (USA), a tributary of the Chesapeake Bay, experienced extensive eutrophication from sewage inputs and non-point sources over four decades (1960-2000 D Elia et al., 2003).

The blooming of red-tide phytoplankton causes problems in our local coastal environment. Bloom is believed to be a result of eutrophication or changes in temperature, salinity, vitamins, metals, or conditions that affect the amount of solar radiation reaching the organisms. The combination of these parameters makes prediction of these blooms extremely difficult. Monitoring such parameters as salinity, pH, dissolved oxygen, or light in a continuous fashion is already practical however, we need to measure parameters of phytoplankton in the same real-time manner to predict accurately the cause of these blooms. 

More generally, UV spectrophotometry can be considered for the monitoring of all compartments of lakes environment. For example, in a recent unpublished work on a eutrophic lake diagnosis, UV spectra of lake and tributaries waters as well as sediment extracts, have been acquired.
