Comparison of extraction methods for polycyclic aromatic hydrocarbon determination in sediments
1990
Different sample preparation methods for the determination of polycyclic aromatic hydrocarbons (PAHs) in lake and river sediments were compared and evaluated. Freeze‐dried sediment materials were e...
Organic chlorine compounds in lake sediments. II Organically bound chlorine
1990
Abstract Organically bound chlorine together with inorganic chloride was measured from dated bottom sediment layers of 18 lakes in Central Finland and compared to organic matter contents. Pulp mills were found to be the source of significant increase of the accumulation of all of these materials in the 20th century.
Organic chlorine compounds in lake sediments. V. Bottom of Baikal near a pulp mill
1990
Abstract Organically bound chlorine (OCl) together with inorganic chloride (Cl − ) was measured from bottom surface samples of the Lake Baikal near a pulp mill and compared to organic matter contents (OM). Although total contents of OCl, Cl − and OM were much lower than, the ratio of OCl to OM was of the same order of magnitude as in pulp mill recipients of Finland.
Estimation of the environmental hazard of organochlorines in pulp mill biosludge used as soil fertilizer
1993
Abstract Contents of total organic chlorine and polychlorinated phenols, guaiacols, catechols, benzenes, cymenes, cymenenes, naphthalenes, toxic dibenzodioxins, toxic dibenzofurans, toxic PCB congener 77, alkylated dibenzofurans, alkylated bibenzyls and alkylated phenanthrenes in spent biosludges from activated sludge treatment plants of chlorobleaching kraft pulp mills are reported. Some estimations of hazard caused by these organochlorines to humans and wildlife from the use of biosludge as soil fertilizer are constructed and discussed.
