Biological impact of lipophilic sediment extracts from the Kafue River, Zambia, in microinjected rainbow trout yolk-sac fry and chick embryo livers exposed in vitro

Autor: L. Norrgren, B. Brunström, M. Engwall, M. Mwase

Publikováno v: Aquatic Ecosystem Health & Management. 1:91-99

Lipophilic sediment extract originating from the Kafue River, Zambia, was evaluated for toxic potency. Two different bioassays were used. In the first, sediment extracts were injected into newly hatched rainbow trout yolk-sac fry, and in the second c

Primary Cultures Of Epithelial Cells From Rainbow Trout Gills

Autor: P. Part, P. Sjoberg, L. Norrgren, E. Bergstrom

Publikováno v: Journal of Experimental Biology. 175:219-232

A method for obtaining primary cultures of epithelial cells from rainbow trout gills is described. The yield of cells from approximately 1.5g wet mass of tissue was 218×106±12×106 cells with a viability defined by eosin exclusion of 80±6%. Cells

The influence of calcium and humic substances on aluminium accumulation and toxicity in the minnow, Phoxinus Phoxinus, at low pH

Autor: L. Norrgren, A. Wicklund Glynn, O. Malmborg

Publikováno v: Comparative Biochemistry and Physiology Part C: Comparative Pharmacology. 102:427-432

1. Minnows, Phoxinus phoxinus , were exposed to acidic water (pH 5) without or with Al (150 μg/l) at different Ca (0, 0.07, 2mM) and humus concentrations (5, 25 Pt-units) for 15 days. 2. Mortality among minnows exposed to acidic water alone decrease
