“…Nutrient enrichment and algal blooms cause problems for water supply and sewerage treatment operators. Some costs are to meet compliances established at national and European levels, especially for nutrients (see section B2ii), while others relate to the adverse effects of algal blooms and their decomposition products, resulting in potable water of an unacceptable quality (27,20,5).…”

“…These arise from high nitrate content of drinking water (no longer a problem in the U.K.) and toxic algal blooms (33,48). Cyanobacteria have caused deaths of livestock at one reservoir in the U.K. and acutely poisoned soldiers at another (5,27,49). As these events appear to be rare, we take these again to be close to zero.…”

“…The value-loss costs related to changes in species composition and loss in ecosystems affected by eutrophication are difficult to measure. Eutrophication has a direct effect on the primary production of plants and, through changes in pH, available light and oxygen concentration and indirectly affects the abundance and nature of organisms within it (5,27,32). However, several important water species and habitats adversely affected by eutrophication are listed in the U.K. Biodiversity, Species and Habitat Action Plans (50).…”

Eutrophication has many known consequences, but there are few data on the environmental and health costs. We developed a new framework of cost categories that assess both social and ecological damage costs and policy response costs. These findings indicate the severe effects of nutrient enrichment and eutrophication on many sectors of the economy. We estimate the damage costs of freshwater eutrophication in England and Wales to be $105-160 million yr -1 (£75.0-114.3 m). The policy response costs are a measure of how much is being spent to address this damage, and these amount to $77 million yr -1 (£54.8 m). The damage costs are dominated by seven items each with costs of $15 million yr -1 or more: reduced value of waterfront dwellings, drinking water treatment costs for nitrogen removal, reduced recreational and amenity value of water bodies, drinking water treatment costs for removal of algal toxins and decomposition products, reduced value of nonpolluted atmosphere, negative ecological effects on biota, and net economic losses from the tourist industry. In common with other environmental problems, it would represent net value (or cost reduction) if damage was prevented at source. A variety of effective economic, regulatory, and administrative policy instruments are available for internalizing these costs.

“…Zooplankton species richness in reduced under chemical stresses (Baker & Christensen, 1991). Lakes and reservoirs deteriorate through excessive addition of plant nutrients, organic matter and silt, which combines to produce increased algae and rooted plant biomass, reduced water clarity, and usually decreased water volumes (Harper, 1992). Nutrient pollution especially with phosphorus but also with nitrogen coming from urban runoff and sanitary sewer systems can lead to the eutrophication of the receiving water bodies (Stevens, 2003).…”

Biodiversity found on Earth today consists of many millions of distinct biological species, which is the product of nearly 3.5 billion years of evolution. This article deals with planktonic distribution of Bhoj Wetland, Bhopal, India . Bhoj Wetland comprises of two lakes i.e. Upper and Lower lakes of Bhopal. The Upper lake is shallow, highly stratified and oligotrophic lake while Lower lake is eutrophic lake. Samples were collected from Upper lake at two sampling stations and in Lower lakes from three sampling stations with their reference stations. The work was carried out for a period of two year (i.e. 2005-2006) in these contrasting lakes @ JASEM

“…This value is over the derigueur limit values for eutrophic lakes (Harper, 1992;Henderson-Sellers and Markland, 1987). In previous studies, PO 4 -P was measured as 0-0.013 mg L -1 (Kazancı et al, 1998), 0.03-0.09 mg L -1 (Arcak and Altındağ, 2000) and 0-0.19 mg L -1 (Girgin et al, 2004).…”

During the period from December 2003 to November 2004 a study has been held to examine the water quality and zooplankton of highly alkaline Lake Burdur. The lake showed thermal stratification between June and October. Six zooplankton taxa were determined, Hexarthra fennica, Brachionus plicatilis from Rotifera and Arctodiaptomus burduricus from Copepoda were the dominant species. Average zooplankton density was 399,074 ind.m -3 and they were 51% H. fennica, 9% B. plicatilis and 40% A. burduricus. In addition, vertical zooplankton distributions have been investigated in this study. Generally, zooplankton groups were concentrated between 5-20 m. However, rotifers and A. burduricus were determined to have the highest density at 5 and 15 m, respectively.
