Updated publication reference for PubMed record(s): 33316748. Mussels (Mytilus galloprovincialis) were exposed during 7 and 28 days in seawater (control), seawater + acetone (solvent control, SC), and 10 micrograms per Litre of tris(1,3-dichloro-2-propyl) phosphate (TDCPP). TDCPP was added from a stock solution prepared in acetone, the volume added being 100 µL per 30 L aquaria. The same volume of acetone was added to SC aquaria. Mussel density was 20 mussels per each 30 L aquaria at the beginning of the experiment and varied between 15 ‒ 20 mussels/30 L aquaria during the 28 days exposure period. Exposure conditions were the following: T = 15.6 ± 0.7 ºC, S = 35.5 ± 0.5 ppt, pH = 7.9 ± 0.1, O2 = 7.9 ± 0.6 mg L-1 and 10:14h light:dark photoperiod. Water was renewed twice per week and mussels were fed before every water renewal with a mixture of phytoplankton representing 1% of mussel tissue dry weight.
