Brock TC, Crum SJ, Deneer JW, Heimbach F, Roijackers RM, Sinkeldam JA: Comparing aquatic risk assessment methods for the photosynthesis-inhibiting herbicides metribuzin and metamitron. Environ Pollut. 2004 Aug;130(3):403-26.
A comparison of the risk assessment procedures reveals that the first-tier approach is the most conservative for metamitron and metribuzin, and that HC5 values (and even HC10 values) based on acute EC50 values of algae and aquatic vascular plants may be used to derive maximum permissible concentrations for single applications. |
