kontaminiertem

Kontaminiertem is the dative singular form of the German adjective kontaminiert, derived from the verb kontaminieren, meaning to contaminate. It functions as a participial adjective describing something that is contaminated and agrees with the noun it modifies in case, gender, and number.

In usage, kontaminiertem occurs when the noun is masculine or neuter in the dative singular and the phrase has no definite article or uses a preposition that governs the dative. Examples include: mit kontaminiertem Material (with contaminated material), aus kontaminiertem Wasser (from contaminated water), auf kontaminiertem Gelände (on contaminated terrain). When a definite article is present, the corresponding forms show the weak declension, for example: dem kontaminierten Boden, dem kontaminierten Material, der kontaminierten Fläche.

Grammatical notes: kontaminiertem is the dative singular form used with masculine or neuter nouns under strong declension or after prepositions requiring the dative without an article. The related forms in other cases include kontaminierter Boden (nominative masculine), kontaminierte Fläche (nominative feminine), and kontaminierte Materialien (plural). With definite articles, the forms shift to dem kontaminierten Boden, der kontaminierten Fläche, dem kontaminierten Material, reflecting the article-driven endings.

The term is common in contexts such as environmental science, public health, safety, and quality control, where describing a material, substance, or site as contaminated is necessary for assessment, regulation, or remediation.
