Effects of a secondary‐treated Thermomechanical Pulp Mill effluent on aquatic organisms as assessed by short‐ and long‐term laboratory tests

Autor: R.H. Voss, J.S. Gibbons, Tibor Kovacs, Pierre H. Martel, B.I. O'Connor

Publikováno v: Journal of Toxicology and Environmental Health. 44:485-502

The chronic effects of secondary-treated effluent from a thermomechanical pulp (TMP) mill were assessed by means of long-term and short-term laboratory toxicity tests. The effluent used for the tests was sampled at a western Canadian mill using mostl

A survey of pulp and paper mill effluents for their potential to induce mixed function oxidase enzyme activity in fish

Autor: B.I. O'Connor, R.H. Voss, T.G. Kovacs, P. H. Martel

Publikováno v: Water Research. 28:1835-1844

The potential of 31 secondary-treated pulp and paper mill effluents from eight different mills to induce mixed function oxidase (MFO) activity, in the liver of rainbow trout (Oncorhynchus mykiss), was investigated by short-term (4-day) laboratory exp

An appraisal of the effect of biological treatment on the environmental quality of high-yield mechanical pulping effluents

Autor: J. G. Dorica, R.H. Voss, J.S. Gibbons, B.I. O'Connor, T.G. Kovacs

Publikováno v: Water Research. 26:1425-1432

Before biological treatment, the effluents from one CTMP (chemi-thermomechanical pulping) and three TMP (thermomechanical pulping) mills were acutely lethal to fathead minnows ( Pimephales promelas ) and the water flea Ceriodaphnia with 48-h LC 50 va

The effect of wood species composition on the toxicity of simulated mechanical pulping effluents

Autor: R.H. Voss, T.G. Kovacs, B.I. O'Connor

Publikováno v: Environmental Toxicology and Chemistry. 11:1259-1270

A series of simulated mechanical pulping (SMP) effluents, prepared from wood species commonly employed in Canada, were analyzed for wood extractives and tested for acute toxicity to fathead minnows (Pimephales promelas) and acute/chronic toxicity to

The effects of a secondary-treated bleached kraft mill effluent on aquatic organisms as assessed by short-term and long-term laboratory tests

Autor: P. H. Martel, T.G. Kovacs, B.I. O'Connor, Louis A. Tremblay, J.S. Gibbons, R.H. Voss

Publikováno v: Ecotoxicology and environmental safety. 31(1)

The chronic effects of secondary-treated effluent from a bleached kraft mill were assessed by means of long-term and short-term laboratory tests. In the long-term test, the effects of the effluent on the life cycle of fathead minnows ( Pimephales pro

A laboratory exposure procedure for screening pulp and paper mill effluents for the potential of causing increased mixed function oxidase activity in fish

Autor: P. H. Martel, R.H. Voss, B.I. O'Connor, T.G. Kovacs

Publikováno v: Environmental pollution (Barking, Essex : 1987). 89(3)

To better understand the relationships between pulp manufacturing processes and mixed function oxidase (MFO) enzyme induction in fish, a practical and standardized exposure procedure is required. This study was undertaken to develop a laboratory-base
