Deutsch: Stressor / Italiano: Stressor - Stressor
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event that causes stress to an organism.
An event that triggers the stress response may include environmental stressors (elevated sound levels, over-illumination, overcrowding) or daily stress events (e.g., traffic, lost keys, quality and quantity of physical activity).
A Stressor indicator is a characteristic of the environment that is suspected to elicit a change in the state of an ecological resource, and they include both natural and human-induced stressors.
Deutsch: Unterteilung / Français: Subdivision
Subdivision in the environmental context refers to the division of a larger piece of land into smaller, individual lots or parcels. This process involves the planning and development of infrastructure and services necessary for the creation of residential, commercial, or industrial areas within the subdivided land. Subdivisions can have significant environmental implications, as they impact land use, habitat, and natural resources. Understanding the application areas, examples, and risks associated with subdivisions is essential for sustainable land development practices.

Sulfur or sulphur (see spelling differences) is a chemical element with symbol S and atomic number 16. It is an abundant, multivalent non-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8. Elemental sulfur is a bright yellow crystalline solid when at room temperature.
Sulfur dioxide (SO2) is a heavy, smelly gas which can be condensed into a clear liquid; used to make sulfuric acid, bleaching agents, preservatives and refrigerants; a major source of air pollution in industrial areas.
Sulphur in the environmental context refers to a chemical element with the symbol 'S' and atomic number 16. It is a naturally occurring element found in various forms in the environment and is an essential element for life. In environmental discussions, sulphur is often associated with its compounds, particularly sulfur dioxide (SO2) and hydrogen sulfide (H2S), which can have both beneficial and detrimental effects on ecosystems and human health.
