Not exact matches

The LCA examined the effects of a 1 kilogram industry - average corrugated product manufactured in 2014 on seven environmental impact indicators: global warming potential (greenhouse gas emissions), eutrophication, acidification, smog, ozone depletion, respiratory effects, fossil fuel depletion; and four inventory indicators: water use, water consumption, renewable energy demand, and non-renewable energy demand.

Nutrient surpluses might result in nutrient losses which could subsequently lead to water and air contamination and eutrophication.

Warming temperatures in the Chesapeake Bay region's streams will have implications for future shifts in water quality, eutrophication and water column layers in the bay.

This process of rampant algae growth leading to oxygen - starved waters is known as eutrophication.

By the 1950s, a declining mayfly population in the western basin of Lake Erie indicated widespread anthropogenic eutrophication (human activities resulting in more nutrients such as phosphorus in the water, leading in turn to decreased oxygen levels).

He's presented research findings based on several analyses he's done that suggest once sucralose levels in a body of water rise above 57 parts per trillion, it's an indicator that the water is experiencing some level of human impact and the onset of eutrophication — nutrient loading that can encourage plant growth and suffocate animal life.

However, wetlands and their bird populations are globally threatened by intensified land use and the results of the degradation of water systems, such as overgrowth and eutrophication.

Over the past 50 years, changes in land use and wastewater inputs have led to eutrophication of the lake, with increased turbidity and oxygen depletion in deeper waters.

eutrophication The process by which a body of water becomes full of nutrients, which then stimulates the excessive growth of plants and algae.

It is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrogen or phosphorus, stimulate algae growth.

The ammonia is washed away, creating a major environmental issue as it leads to eutrophication of water ways and ultimately enters the atmosphere as nitrogen dioxide, the main greenhouse gas associated with agriculture.

The main areas covered in this work booklet are: Species Classification Distribution of organisms Sampling Predator prey graphs Adaptations Pyramids of biomass Carbon cycle Water cycle Eutrophication Global warming Food security Sustainable fisheries Microprotein Within the booklet are a range of different activities for students to work through to help them remember the content.

However, if one considers the enormous increase of reactive nitrogen in our biosphere, due to the use of synthesized fertilizer and the burning of fossil fuels, its impact is not part of the analysis, even tough this increase shows up in the eutrophication (nutrient enrichment) of open waters all over the world, resulting in excess algae, in some areas causing large algae blooms (as where they are going to hold the sailing regattas during the Olympics), red tides and dead zone, as the 8000 square mile dead zone in the Gulf of Mexico.

These include eastern boundary current upwelling systems such as those off the U.S. west coast along coastal California, Oregon and Washington, deep - sea and subsurface oxygen minimum zones, and coastal waters that are already experiencing excess nutrient levels (eutrophication) and low dissolved oxygen (hypoxia) due to human - driven nutrient pollution from land - based activities.

They report in Environmental Research Letters that they examined 740 different production systems for 90 different foods, to calculate levels of land use, greenhouse gas emissions (GHGs), fossil fuel energy use, the nutrient runoff that leads to eutrophication or «dead zones» in lakes and rivers, and the potential for acidification of the waters.

Eutrophication - The process by which a body of water (often shallow) becomes (either naturally or by pollution) rich in dissolved nutrients, with a seasonal deficiency in dissolved oxygen.

At the same time, eutrophication may promote larger CH4 emissions, both by reducing O2 concentrations in reservoir bottom waters and by increasing organic matter quantity (as described below).

In southern Europe, to compensate for increased climate - related risks (lowering of the water table, salinisation, eutrophication, species loss)(Williams, 2001; Zalidas et al., 2002), a lessening of the overall human burden on water resources is needed.

ESM 202 - Environmental Biogeochemistry [4 units] Melack & Holden Biogeochemical processes as applied to the Earth's atmosphere, oceans, land, and inland waters, and applications to environmental issues such as eutrophication, toxic pollution, carbon sequestration, and acidification.

These hypoxic areas — virtually uninhabitable for most marine life — are a result of eutrophication, or too many nutrients from fertilizer runoff and sewage discharges finding their way into coastal waters.

Although eutrophication is the major concern related to these inputs, the pH of coastal waters is also influenced through the enhanced CO2 uptake from primary production and CO2 release from respiration associated with increased nutrient inputs.

This guidance document examines the main commercially available renewable and non-renewable power generation technologies, analysing their GHG emissions, but also trade - offs in terms of: 1) environmental impacts (impacts on ecosystems, eutrophication and acidification, etc.), 2) impacts on human health (particulates, toxicity) and 3) resource use implications (concrete, metals, energy intensity, water use and land use).

Discharge from sewage treatment plants and runoff from agricultural fields contaminate bodies of water with excess phosphorus, leading to eutrophication.

Nutrients like phosphorus and nitrogen are necessary for plant growth, but excess nutrients in a water system can cause a dangerous form of pollution known as eutrophication.

The lakes ECV is of relevance to biogeochemical cycling, eutrophication, mesoscale climate models, human impact, vegetation dynamics, water cycle, and radiation budget climate studies.

The organic matter that eventually sinks out of the surface waters is decomposed by hordes of hungry decomposers, which consume large amounts of oxygen during the process (see: eutrophication).

In the long run, the excess algal growth can have devastating impacts on the health and age of a fresh water lake or river, causing eutrophication to speed up, where lakes and other water bodies fill in with dead algae and other organic matter and eventually turn into dry land.

They are worsened by eutrophication, or a density of nutrients, as well as sewage inputs in coastal waters.
