Species sensitivity distribution (SSD) is an approach to define safe levels for toxic compounds in an ecosystem. It is based on the assumption that species sensitivity to a given contaminant can be described by a probability distribution estimated from toxicity experiments.

Based on this framework, MOSAICSSD is able to estimate the so-called hazardous concentration for x% of the species (HCx), even when the toxicity values are censored

MOSAICSSD is based on the R package fitdistrplus . For more details, please consult the companion paper .
