One of the key problems related to water pollution is the presence of odorous nitrogen compounds, especially ammonia, which often lacks a clearly defined odour threshold value. Odour intensity does not always correlate directly with gas concentration, and this complexity has encouraged broader scientific cooperation, such as the COST Action CA18225 “Taste and Odor in early diagnosis of source and drinking Water Problems” (2019–2023), which focuses on taste and odour issues in water. The work aimed to determine the dependencies between odour concentration and the temperature and concentration of an aqueous ammonia solution. A method was developed to measure odour concentration in water contaminated with ammonia at various levels. Results show that increasing solution temperature significantly raises odour concentration in the air: from 616 OUE/m³ at 20°C to 1052 OUE/m³ at 30°C and 1758 OUE/m³ at 40°C. The odour threshold also rises with temperature, doubling between 20°C and 30°C. Knowing odour emission flow enables modeling odour dispersion in ambient air.
