Etymology: "Ecotoxicological" is a modern scientific compound, built by joining "eco-" to "toxicological," and its parts have very different histories. The "eco-" element comes from the Greek "oikos," meaning "house" or "household," which gave English words like "economy" (household management) and "ecology" (the study of organisms in their habitats). "Toxicological" is the adjective for toxicology, the study of poisons, and it descends from the Greek "toxikon," the poison in which arrows were dipped, plus the suffixes that turn a noun into an adjective. Because "eco-" is a prefix that English speakers use freely, the combined word is easy to form, and it is a technical term rather than one with an older everyday life. The word is used to describe effects, studies, or assessments that concern the harm poisonous substances cause to ecosystems, including plants, animals, and their interactions, not just to individual humans. Its meaning is therefore essentially the sum of its parts: the toxicology of the environment.
