911 Turbo AWD (997) F6-3.6L Turbo (2010)
The variation range in the biological balance, which represents a buffer or compensation possibility.
Ecology
Biology: analyses the relationship between living organisms and their animate and inanimate environment, primarily concerned with various different
biotopes and microbiota and analyzing the life functions in their natural surroundings or on location.
Economic injury level
Damage limit that exists if the damage expected to be caused by a harmful element is equal in cost to the defence against this element, i.e. damage is felt
economically only if it exceeds the costs for combating the damage. Making use of the economic injury level is an important characteristic of integrated
pest management. The economic injury level of parasites, diseases and weeds are only known for very few agricultural and gardening cultures.
Ecosystem
Ecological term that comprises biotope and the accompanying biocoenosis.
EIA
See: Environmental impact assessment.
EINECS
Abbreviation for European Inventory of Existing Chemical Substances. Index, published by the EC Commission, of approx. 98,000 substances used
commercially in the European Community before 18.09.1981. The so-called old substances listed in EINECS do not need to be tested or registered in the
member states. For a large number of these substances, there are already findings, in particular toxicological data.
Electrostatic cleaning
A method of removing suspended particles from gases by means of electrostatic fields.
Emission measurements
For the qualitative and quantitative determination of Emissions. They are not only important for obtaining an overview of various types of emissions, but
also for monitoring production in the various facilities. The measuring instruments, e.g. which continuously check the waste gas concentrations in the air
above a factory and report any deviations to a central office, are state of the art (e.g. incorporating laser technology).
Emissions
Gaseous, liquid or solid substances entering the atmosphere from a facility or a technical process; noise, vibrations, light beams, heat and radioactivity,
and also liquid and solid substances that do not enter the atmosphere but other ecological systems. Emissions from a causative source result in pollution
(See: Immission) in the adjacent environment which decreases with increasing distance.
Emitter
The cause of Emissions.
Emulsifiers
Surface-active substances for emulsifying fats and oil in water.
Emulsion
System of two immiscible liquids, in which one liquid (the dispersed phase) is finely distributed in another (disperser or dispersing medium) in the form
of tiny droplets (disperse system). Milk is the most common example of an emulsion. Washing is an emulsion process in which fat and dirt are emulsified
in water by the detergent and can then be rinsed out. Everyday emulsions include cosmetic creams.
Endothermic process
Chemical processes requiring the input of heat.
Energy
The ability of a system to perform work. According to the law of conservation of energy, there is a fixed relationship - termed energy equivalent -
between interconvertible forms of energy.
