Toxicity Exposure Ratio

Toxicity Exposure Ratio

Die Toxicity Exposure Ratio (abgekürzt TER) ist ein Risikoindikator zur Risikobewertung von Pflanzenschutzmitteln. Sie gibt das Verhältnis von Schad-Konzentration zur geschätzten Einwirkungs-Konzentration für einen Organismus (akut, chronisch) an [1]

Je höher der TER, desto geringer ist das Risiko.


TER = \frac{\text{Toxizitaet (EC50 / LC50 oder NOEC)}}{\text{Exposition (PEC)}}
