The study gives great insights into how sediment organic carbon influences Irgarol 1051 toxicity in meiobenthic communities, but a couple of things could use more clarification. First, the porewater concentrations were estimated using partitioning equations; were any direct measurements taken to confirm these estimates? Since organic carbon interactions can vary, some experimental validation would really help strengthen the findings.
Also, the paper looks at how different nematode feeding groups respond but doesn’t fully explore whether indirect effects, like shifts in microbial food availability or trophic interactions, played a role. Could the authors expand on how these factors might have influenced the observed toxicity responses?
