Water quality – is a description of water’s chemical and biological composition and physical properties, which characterize it as an abiotic component of aquatic ecosystem and determine its suitability for specific consumption purposes. Ecological water quality (environmental water quality) – refers to the ecological well-being of an aquatic ...

TEMPORARY RIVERS: LINKING ECOHYDROLOGY, ECOLOGICAL QUALITY AND RECONCILIATION ECOLOGY
River Research and Applications, 2014ABSTRACT Temporary streams and rivers, also referred to as intermittent, are defined as waterways that cease to flow at some points in space and time along their course. They are shaped by alternating wet and dry periods over annual and inter‐annual cycles, making them one of the most dynamic freshwater ecosystems.

The Need of an Ecological Quality-Concept
Environmental Monitoring and Assessment, 1983Quality assessments with respect to our environment are done in many different ways. Generally these assessments are connected with functions which the environment has to accomplish for man. These are partial approaches in which some characteristics are selected from the complex reality.

Human ecology and the quality of life
Urban Ecology, 1978Abstract In all human situations there is a constant interplay between variables of different kinds — physical, chemical, biotic, social, cultural and economic. We refer to the study of patterns of interaction between these different components of human situations as ‘human ecology’.

Systemic and Ecological Qualities of Families
2013Systems theory and its offspring family systems theory have evolved and matured over the course of some 4 decades. The developmental history of family systems theory has been rich. If a theory is judged by its utility, or as Kuhn (1962) proposed, by the number of adherents it wins in the scientific community, then family systems theory has accomplished

Hydrology and the ecological quality of Scottish river ecosystems
Science of The Total Environment, 2002Hydrology is a primary control on the ecological quality of river systems, through its influence on flow, channel geomorphology, water quality and habitat availability. Scottish rivers are widely perceived to be of high ecological quality, with abundant flow volumes and high water quality.

Ecological quality assessment of the lower Lima Estuary
Marine Pollution Bulletin, 2010Monitoring biotic factors is gaining in importance within Europe, due in large extent to the ecological approach of the European Water Framework Directive (WFD) and the importance attributed to biological elements in the assessment of quality status. Despite its ecological importance, the Lima Estuary is subjected to a range of perturbations, including

Chemical contamination and the ecological quality of surface water
Environmental Pollution, 2010In the assessment of the quality of surface waters, the typical procedure is that the concentration of contaminants in the surface water is monitored and subsequently compared with their respective Maximum Permissible Concentrations (MPCs). If the MPCs are not exceeded the water quality is considered to be safe. But can we be certain that this is true?

Ecotoxicology, 1993
: Extrapolation methods form the basis for most recent techniques used to set 'safe' levels of toxicants for ecosystems. Most methods use information from several single species toxicity tests to predict safety factors for protecting all species in all communities in a nation or group of nations.
