Effect of Ca-Rich Granulated Oil Shale Ash Amendment on Leaching Properties of Peat Soil: Experimental and Field Study

Autor: N. Irha, J. Reinik, K. Ots

Publikováno v: Eurasian Soil Science. 54:1097-1106

The combustion of low-grade solid fuels such as oil shale generates huge amounts of solid wastes such as fly ash. Use of oil shale combustion ash in granulated form for liming and amending peat soil has been suggested as a feasible recycling opportun

Role of Algae in Fate of Carcinogenic Polycyclic Aromatic Hydrocarbons in the Aquatic Environment

Autor: N. Irha, U. Kirso

Publikováno v: Ecotoxicology and Environmental Safety. 41:83-89

Polycyclic aromatic hydrocarbons (PAHs) represent an ecotoxicologically relevant, combustion-related substance group. The bioconcentration and transformation of a priority PAH, benzo[a]pyrene (BaP), by brown (Fucus vesiculosus and Chorda filum), red

Model studies of photochemical oxidation of carcinogenic polyaromatic hydrocarbons

Autor: E. Urbas, L. Paalme, N. Irha, A Tsyban, U. Kirso

Publikováno v: Marine Chemistry. 30:105-111

Twenty-eight different polyaromatic hydrocarbons (PAHs) in water and on thin-layer plates with Al2O3 or SiO2 have been irradiated, using high-pressure mercury-quartz lamps. The degradation rates differ by two orders of magnitude, and the process is m

Accumulation of carcinogenic hydrocarbons at the sediment-water interface

Autor: E. Urbas, N. Irha, L. Paalme, M. Voll, U. Kirso

Publikováno v: Marine Chemistry. 30:337-341

Polyaromatic hydrocarbons (PAHs) were determined at different depths, at the sediment-water interface, in sediments and in benthic algae at stations in the Gotland Deep and the Gulf of Finland. Pyrene is the main PAH in the water and the algae, where
