摘要: Abstract This work presents the results of an interlaboratory proficiency exercise for whole-sediment toxicity assays with benthic marine diatom Cylindrotheca closterium . An assay protocol was established and followed by all participating laboratories. Cell growth after 72 h exposure endpoint used. Four sediment samples unknown were assayed. The main problem encountered during this differences in cell algae exposed to reference sediment. Those may be associated changes physiological status initial culture due temperature transport other In general, method proposed presented good replicability (precision between replicates) reproducibility (interlaboratory precision). Around 80% (17 out 21) obtained classified as satisfactory ( Z -scores C here can considered sufficiently successful possible use a standard test. is simple perform, species ecologically relevant integral component microphytobenthos, widely distributed around world. These positive factors suggest that C. used reliable tool quality assessment.
