Aruoja, V.; Moosus, M.; Kahru, A.; Sihtmäe, M.; Maran, U. Measurement of baseline toxicity and QSAR analysis of 50 non-polar and 58 polar narcotic chemicals for the alga Pseudokirchneriella subcapitata. Chemosphere 2014, 96, 23-32

Published: Villem Aruoja, Maikki Moosus, Anne Kahru, Mariliis Sihtmäe, Uko Maran (2013-06-27)

Abstract: In this paper a set of homogenous experimental algal toxicity data was measured for 50 non-polar narcotic chemicals using the alga Pseudokirchneriella subcapitata in a closed test with a growth rate endpoint. Most of the tested compounds are high volume industrial chemicals that so far lacked published REACH-compliant algal growth inhibition values. The test ...

Furuhama, A.; Hasunuma, K.; Aoki, Y. Interspecies quantitative structure–activity–activity relationships (QSAARs) for prediction of acute aquatic toxicity of aromatic amines and phenols. SAR QSAR Environ. Res. 2015, 26, 301–323.

Published: Geven Piir, Sulev Sild (2017-05-08)

Abstract: We propose interspecies quantitative structure–activity–activity relationships (QSAARs), that is, QSARs with descriptors, to estimate species-specific acute aquatic toxicity. Using training datasets consisting of more than 100 aromatic amines and phenols, we found that the descriptors that predicted acute toxicities to fish (Oryzias latipes) and algae were ...

Published: Iiris Kahn (2015-01-26)

Abstract: Using seawater for toilet flushing effectively reduces the consumption of precious freshwater resources, yet it introduces bromide and iodide ions into a wastewater treatment system, which may form bromo- and iodo-disinfection byproducts (DBPs) during chlorination of the wastewater effluent. Most of the newly identified DBPs in chlorinated wastewater effluents ...

Lu, G.-H.; Yuan, X.; Zhao, Y.-H. QSAR study on the toxicity of substituted benzenes to the algae (Scenedesmus obliquus). Chemosphere 2001, 44, 437–440.

Published: Iiris Kahn (2015-03-31)

Abstract: 50% effective inhibition concentration 48h-EC50 of 40 substituted benzenes to the algae (Scenedesmus obliquus) was determined. The energy of the lowest unoccupied molecular orbital (ELUMO) was calculated by the quantum chemical method MOPAC6.0-AM1. By using ELUMO and the hydrophobicity parameter log Kow the quantitative structure–activity relationship model ...
