Preliminary study on brominated dioxins/furans and hydroxylated/methoxylated PBDEs in Baltic cod (Gadus morhua) liver. Comparison to the levels of analogue chlorinated co-occurring pollutants.

Mar. Pollut. Bull. 96 , 165-75, (2015)

Low pg levels of PBDD/Fs in 0.8-38.9 pg g(-1) (fat) range (mean 14.2 pg g(-1)) observed in the tested cod liver samples were significantly lower than levels of their chlorinated analogues (25.1-95.9 r...

Acidogenic fermentation of Scenedesmus sp.-AMDD: Comparison of volatile fatty acids yields between mesophilic and thermophilic conditions.

Bioresour. Technol. 200 , 624-30, (2015)

This study compared the acidogenic fermentation of Scenedesmus sp.-AMDD at laboratory-scale, under mesophilic (35°C) and thermophilic conditions (55°C). Preliminary batch tests were performed to evalu...
