AB  - A time-trend study was carried out for two important Baltic Sea species, blue 
      mussel (1994-2017, 11 samples) and eelpout (1994-2017, 11 samples), to track the 
      changes in levels of regulated persistent organic pollutants (POPs) and show 
      potential increases in the levels of the contaminants of emerging concern (CECs). 
      It was carried out utilizing gas chromatography-high-resolution mass spectrometry 
      (GC-HRMS) based non-target screening (NTS). Data were acquired in two modes - 
      electron ionization (EI) and electron capture negative ion chemical ionization 
      (ECNI) - to widen the contaminant coverage, and treated using a fast 
      semi-automated NTS data processing workflow. The study revealed that >250 
      tentatively identified compounds show statistically significant temporal trends 
      in Baltic blue mussel and eelpout. A large number of regulated substances, 
      including but not limited to PCBs, DDTs and other organochlorine pesticides 
      (OCPs), chlorobenzenes, and many polybrominated diphenyl ethers (PBDEs), showed 
      significant declining trends, as was expected. Their rates of decline were in 
      good agreement with previously reported data. In contrast, increasing trends were 
      observed for many CECs, some polycyclic aromatic compounds (PAHs), and 
      hydrocarbons. The CEC group included, among others, four compounds, namely, one 
      personal care product ingredient, 2-ethylhexyl stearate, one brominated compound 
      1,2,3,5-tetrabromobenzene and two intermediates 4-isopropoxyaniline and bilobol 
      dimethyl ether, that were reported in marine biota for the first time to the best 
      of our knowledge. Several compounds, including four CECs and two unknown 
      brominated compounds, showed levels considerably higher than the common legacy 
      pollutants (CB-153 and BDE-99), which might be taken into consideration for 
      future monitoring and risk assessment. In addition, this work revealed the 
      presence of a plethora of organoiodinated compounds that exhibited statistically 
      significant temporal trends in the samples under study, which could be of future 
      interest.
