Deutsch: Standardabweichung / Español: Desviación estándar / Português: Desvio padrão / Français: Écart type / Italiano: Deviazione standard

Standard deviation is a statistical measure that indicates the amount of variation or dispersion within a set of data. In the environmental context, it helps quantify the variability in environmental measurements, such as temperature, rainfall, pollution levels, or biodiversity. By analyzing standard deviation, scientists can better understand how consistent or variable environmental data are, allowing for more accurate predictions, trend analyses, and decision-making in areas like climate science, resource management, and pollution control.

A Standard operating procedure is a written document which details an operation, analysis, or action whose mechanisms are prescribed thoroughly and which is commonly accepted as the method for performing certain routine or repetitive tasks.

Deutsch: Startup / Português: Startup / Italiano: Startup

Start-up in the environmental context refers to a newly established company or organization that focuses on innovative solutions, products, or services aimed at addressing environmental challenges and promoting sustainability. These companies often leverage technology, research, and creative approaches to tackle pressing environmental issues.

The State Implementation Plan (SIP) is a detailed description of the programs a state will use to carry out its responsibilities under the Clean Air Act.

Deutsch: Stationäre Phase / Español: Fase estacionaria / Português: Fase estacionária / Français: Phase stationnaire / Italiano: Fase stazionaria

Stationary phase in the environmental context primarily refers to a stage in the life cycle of populations, ecosystems, or microbial cultures where growth rates slow down and stabilize, reaching a balance between resource availability and population size. This concept is critical for understanding how populations adapt to the carrying capacity of their environment and the implications for sustainability and resource management.

A Statistical control chart (Shewhart control chart) is a graphical chart with statistical control limits and plotted values (for some applications in chronological order) of some measured parameter for a series of samples.

Deutsch: Stichprobe / Español: Muestra estadística / Português: Amostra estatística / Français: Échantillon statistique / Italiano: Campione statistico

Statistical sample in the environmental context refers to a subset of data or a collection of samples from a larger population within an environmental study. This concept is crucial for conducting research and assessments in environmental science, as it allows scientists to make inferences about larger ecosystems or populations based on the properties of the smaller, manageable subset.

Deutsch: Stahl / Español: Acero / Português: Aço / Français: Acier / Italiano: Acciaio /

In the environmental context, "steel" refers to a versatile and widely used material that has both positive and negative implications for the environment. Steel is an alloy primarily composed of iron and carbon, along with small amounts of other elements. It is known for its strength, durability, and resistance to corrosion, making it a preferred material in various industries and applications.

Deutsch: Sterilisator / Español: Esterilizador / Português: Esterilizador / Français: Stérilisateur / Italiano: Sterilizzatore

Sterilizer refers to agents or devices used to destroy all forms of microbial life, including bacteria, viruses, spores, and fungi, typically used in medical, laboratory, and food preparation environments. In the environmental context, sterilizers play a critical role in preventing the spread of infectious diseases and maintaining sterile conditions in various settings.

Deutsch: Hochwasserschutzdamm / Español: Dique de contención / Português: Banco de proteção contra inundações / Français: Digue de protection / Italiano: Argine anti-inondazione

Stopbank in the environmental context refers to an embankment or raised structure built alongside rivers, lakes, or coastal areas to protect adjacent land from flooding. Stopbanks are part of flood management systems designed to direct or contain water flow during high-water events, thereby preventing damage to communities, farmland, and infrastructure.
