Monitoring trend

To identify the enviromnental settings (water body type and geographic location) that would be most sensitive for detecting changes in atmospheric deposition of mercury in a trend-monitoring program...

Third, continued periodic monitoring of fishery and wildlife resources is important, especially in areas with potential for reservoir development, in light of the hypothesis that increased flooding increases the availability of mercury to biota. The use of museum collections for mercury analysis is strongly recommended for monitoring purposes. For example, the Environmental Specimen Bank at the Swedish Museum of Natural History constitutes a base for ecotoxicological research and for spatial and trend monitoring of mercury and other contaminants in Swedish fauna (Odsjo et al. 1997).

Each of the model frameworks in Figure 11.10 could come with a default implementation framework. Our design, at the level of framework-sized components, would look like Figure 11.11. Each of the framework components has its plug-points suitably filled by implementation units from this problem domain. Thus, the instructor allocator has Instructor and Session as plug-ins for Resource and Job and the trend monitor has Session and Topic plugged in for Indication and Product.

It may not be appropriate to consider the scattering coefficient to be constant, and this point may become important in evaluation of trends monitored during a catalytic reaction experiment. Kortiim et al. (1963) pointed out that the scattering behavior depends on the ratio of refractive indices of the sample and the surrounding medium. As an example for a change in the refractive index of the sample, Kortiim described the adsorption of water, which reduces the scattering coefficient. Hence F(p) will increase, which could erroneously be interpreted as an increase in absorption.

The documentation of progressive reduction in concentrations of priority substances and other pollutants, and the principle of no deterioration, are key elements of the WFD and require appropriate trend monitoring. Member states should consider this when designing their monitoring programmes. Data obtained in surveillance and operational monitoring may be used for this purpose. 

Hydrophobic and lipophilic substances that tend to accumulate in sediment and biota should be monitored in these matrices for resource effective trend monitoring in order to ... 

The locations for sediment trend monitoring should be representative of a water body or a cluster of water bodies. Where possible, sampling should be performed in non-erosion areas that are representative of the respective sediment formation. For dynamic systems, it might be useful to collect suspended matter. 

In case of using biota in trend monitoring, it is common practice to collect samples at least once a year during die non-spawning season.

To understand and evaluate the distribution and availability of organic substances and metals, fish are collected from 32 lake sites and taken to a specimen bank. Some of these fish sampling stations have been run continuously since 1964, but others are more recent. The species normally used are perch and arctic char, and in a few cases pike and roach. The sites for specimen banking are, with two exceptions, situated at stations for reference or trend monitoring to get information from supporting parameters. A...
