| Algal blooms, toxin production and eutrophication occur as a result of this phosphorous. |
|
| Finally, pollutants can change the nutrient balance of a waterbody, making it over-rich, a process known as eutrophication. |
|
| At present, the most common and serious anthropogenic perturbation of lakes is eutrophication due to increased nutrient availability. |
|
| She said emissions to air, waste management and water eutrophication required urgent action. |
|
| Nutrient pollution or eutrophication is caused by the massive discharges of nitrates and phosphates into the environment. |
|
| The eutrophication causes ecological disturbance of water, which leads to death of fish, shrimp, swan mussel and other species. |
|
| A five-year research program will address the role of nitrogen in acidification and eutrophication. |
|
| A closure of the anthropogenic phosphorus cycle may help to avoid eutrophication, hypoxia, and other negative impacts on ecosystems and promotes resources conservation. |
|
| In addition, samples are taken for research concerning eutrophication and algal blooms. |
|
| Levels of sulphur dioxide, a major source of acid rain, have declined over recent years, but pollutants causing eutrophication have been increasing. |
|
| In addition, their sensitivity to changes in nutrient levels makes them ideal indicators for assessing eutrophication. |
|
| We are experiencing cultural eutrophication, which means that through human activity we are getting regular algae blooms. |
|
| Eutrophication: eutrophication of an aquatic environment originally refers to its becoming richer in nutrients, with no negative connotation. |
|
| The emphasis of the early 1970s on eutrophication soon turned to a focus on persistent organic pollutants that were showing up in wildlife. |
|
| Prey species may be reduced, while sedimentation, nutrient over-enrichment and salinity, and in turn eutrophication, increase. |
|
| Particular attention is therefore given to the impact of excess nutrients in the Baltic Sea itself leading to eutrophication and algal blooms. |
|
| In our study area, eutrophication promotes excessive growth of filamentous green algae in shallow coastal areas during late spring and early summers. |
|
| Livestock creates eutrophication as well and contributes to acidification and producing greenhouse gases. |
|
| Major environmental issues in the Narva River and Lake Peipsi basin are water eutrophication and management of the lake's fish resources. |
|
| This can have a big effect, especially upon the situation regarding eutrophication and lack of oxygen in the Baltic. |
|
|
|
| Ulva blooms are an indication of eutrophication and this may be more relevant to Irish moss growth and or survival in Basin Head lagoon. |
|
| Water pollution and subsequent eutrophication also reduces the availability of fresh water. |
|
| Surface runoff occurring within forests can supply lakes with high loads of mineral nitrogen and phosphorus leading to eutrophication. |
|
| In recent years studies and research, has provided much insight into processes like eutrophication, and how to deal with it. |
|
| This can cause eutrophication where plant growth is accelerated by the additional material. |
|
| Excess sediment, nutrients, and algae can result in the eutrophication of a body of water. |
|
| Once translocated to lakes, the extraction of phosphate into water is slow, hence the difficulty of reversing the effects of eutrophication. |
|
| Cultural Eutrophication is the process that speeds up natural eutrophication because of human activity. |
|
| Policy changes to control point sources of phosphorus have resulted in rapid control of eutrophication. |
|
| Although eutrophication is commonly caused by human activities, it can also be a natural process, particularly in lakes. |
|
| Terrestrial ecosystems are subject to similarly adverse impacts from eutrophication. |
|
| Many terrestrial plant species are endangered as a result of soil eutrophication, such as the majority of orchid species in Europe. |
|
| The eutrophication of areas outside its natural range partially explain the fish's success in colonising these areas after being introduced. |
|
| In order to gauge how to best prevent eutrophication from occurring, specific sources that contribute to nutrient loading must be identified. |
|
| Future studies should also examine the role of macrophytes in the process of eutrophication at this reservoir. |
|
| The main cause is human disturbance, most notably eutrophication, mechanical destruction of habitat, and overfishing. |
|
| In the late 1980s, a number of European countries and some U. S. states eliminated phosphates from soaps with a view to avoiding eutrophication of waterways and the formation of mucilage in sea water. |
|
| We hope in particular that the strategy will expedite the clean up of the Baltic Sea, which is suffering from eutrophication, and help find common solutions to cross border challenges. |
|
| Aquatic systems may change from oligotrophic to eutrophic, or the rate of eutrophication of a natural eutrophic system may be accelerated by the addition of nutrients and organic matter due to human activities. |
|
| In the end, the project served to identify certain bacterial variables, such as the assimilation of monosaccharides as a relevant tool for diagnosing the eutrophication levels of lakes and reservoirs. |
|
|
|
| Algal blooms and eutrophication expected to increase. |
|
| Overfishing, eutrophication, anoxia, sea-floor degradation and chemical contamination are some of the challenges that have faced the northern Adriatic ecosystem in the last 30 years. |
|
| In erosional riverine habitats, the data suggested that evenness was reduced in exposure areas, which may reflect the sensitivity of organisms in these habitats to even mild eutrophication. |
|
| Deposition of oxidized nitrogen causes acidification and eutrophication. |
|
| It also contains nutrients such as nitrogen and phosphorous which can damage freshwaters and the marine environment by promoting excessive growth of algae that chokes off other life, a process known as eutrophication. |
|
| Two methods are used to correct eutrophication. |
|
| In effect, rivers are used as open sewers for municipal wastes, which results not only in the direct degradation of water quality but also in eutrophication. |
|
| Natural rates of eutrophication are normally relatively slow. |
|
| I believe it is time for the countries in the region to start working more closely together in order to tackle regional challenges, such as pollution and eutrophication. |
|
| Variations in farm density and the distribution of farms and other sources will also influence the probability of far-field eutrophication effects from all sources. |
|
| The algae proliferated to the extent that eutrophication would have taken only a few decades if efforts to rehabilitate the lake had not been undertaken recently. |
|
| Agricultural inputs of phosphorus during critical eutrophication periods in summer might be lower than inputs of this nutrient in municipal wastewater. |
|
| Emissions from agriculture and wastewater systems lead to eutrophication and emissions from industry and waste treatment plants pollute the oceans with chemicals. |
|
| Environmental constraints are very significant since the lake is the main source for the supply of drinking water in the region, but is also very polluted with an eutrophication which is rapidly worsening. |
|
| Fertilizer runoff from surrounding agricultural land has exacerbated the problem and led to increased eutrophication. |
|
| Runoff from sewage, urban land use, and fertilizers can also contribute to eutrophication. |
|
| The beauty of the area is damaged by eutrophication, which is detrimental to the tourism industry. |
|
| The first stage in reversing eutrophication in the Broads is to reduce phosphate input. |
|
| These nutrients are major nonpoint pollutants contributing to eutrophication of aquatic ecosystems. |
|
| The main threats it faces are eutrophication and the introduction of alien species of fish which eat its eggs and fry. |
|
|
|
| The current population trend is unknown and the main threats are thought to be eutrophication and the introduction of alien species. |
|
| Phytoplankton photopigments as indicators of estuarine and coastal eutrophication. |
|
| Sediment diatom assemblages and composition of porewater dissolved organic matter reflect recent eutrophication history of Lake Peipsi. |
|
| The importance of internal phosphorus load to the eutrophication of lakes with anoxic hypolimnia. |
|
| It's the same situation with nitrogen, the twin culprit with phosphorus, causing eutrophication of the waters. |
|
| Any factor that causes increased nutrient concentrations can potentially lead to eutrophication. |
|
| It has also been shown that the drying of wetlands causes an increase in nutrient concentration and subsequent eutrophication blooms. |
|
| One proposed solution to eutrophication in estuaries is to restore shellfish populations, such as oysters and mussels. |
|
| The literature suggests, though, that when these sources are controlled, eutrophication decreases. |
|
| Waste disposal technology constitutes another factor in eutrophication prevention. |
|
| The role of the public is a major factor for the effective prevention of eutrophication. |
|
| Bokashi is a modern method of eutrophication prevention to decrease smell and toxic materials. |
|
| The occurrence of eutrophication in bodies of water is another effect large urban populations have on the environment. |
|
| It is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrates or phosphates, stimulate algae growth. |
|
| Runoff can wash out the mineral nitrogen and phosphorus from detritus and in consequence supply the water bodies leading to slow, natural eutrophication. |
|
| Studies conducted in the Experimental Lakes Area in Ontario have shown a relationship between the addition of phosphorus and the rate of eutrophication. |
|
| The Secchi disk is commonly used to test for eutrophication. |
|
| Reducing eutrophication should be a key concern when considering future policy, and a sustainable solution for everyone, including farmers and ranchers, seems feasible. |
|
| Oospore counts start to decline already in the 1960s, preceding historically recorded changes and anthropogenic eutrophication almost by two decades. |
|
| These problems, including eutrophication caused by ammonia and nitrogen oxides, as well as damage caused by O3 to plants, are still widespread across Europe, it concluded. |
|
|
|
| Changes in farming practices and sewage disposal in the 1950s and 1960s released high levels of phosphorus and nitrogen into the Broads, causing eutrophication. |
|
| The technology to safely and efficiently reuse waste water, both from domestic and industrial sources, should be a primary concern for policy regarding eutrophication. |
|
| The main difference between natural and anthropogenic eutrophication is that the natural process is very slow, occurring on geological time scales. |
|
| However, a more recent study found that eutrophication impacts are in some cases higher from organic production than they are from conventional production. |
