Towards a reliable prediction of the aquatic toxicity of dyes

ENVIRONMENTAL SCIENCES EUROPE, 31(1).

By: G. Umbuzeiro*, A. Albuquerque *, F. Vacchi *, M. Szymczyk n, X. Sui n , R. Aalizadeh *, P. Ohe, N. Thomaidis, N. Vinueza  n, H. Freeman n

Contributors: G. Umbuzeiro*, A. Albuquerque *, F. Vacchi *, M. Szymczyk n, X. Sui n , R. Aalizadeh *, P. Ohe, N. Thomaidis, N. Vinueza  n, H. Freeman n
