Biochemical and physiological effects in fish exposed to bleached kraft mill effluents

Ecotoxicology and Environmental Safety
Lars FörlinA Larsson

Abstract

The studies were performed on perch (Perca fluviatilis) caught outside Husum and Iggesund kraft pulp mills in 1985 and 1987, respectively, and the results were compared to previous observations from 1984 to 1985 in the receiving waters of the Norrsundet kraft pulp mill. The studies revealed that the biochemical and physiological variables, i.e., EROD activity, gonad size, number of lymphocytes, carbohydrate metabolites, and plasma ion composition, can be used as sensitive and reliable indicators of toxic effects on natural populations of fish exposed to conventional chlorine-bleached kraft mill effluents. However; the effects were generally less pronounced and indicated less geographic extension than those seen in perch previously investigated in the receiving waters of the Norrsundet kraft pulp mill. Based on these studies on perch at Husum and Iggesund and the previous studies at Norrsundet it can be concluded that the chlorine-bleached kraft mill effluents cause serious disturbances to vital biochemical and physiological functions, which can affect the health status and presumably also the survival of the fish. Finally, the responses do not reflect the present situation in the receiving waters since all three mills have take...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
