Biological effects of contaminants: Quantification of metallothionein (MT) in fish liver tissue.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1999)This document describes methods to analyse the protein metallothionein in fish tissues. Metallothionein is induced by and binds essential (Cu, Zn) and non-essential (Cd, Hg) metals and is used in monitoring programmes as ... -
Biological effects of contaminants: Quantification of δ-aminolevulinic acid dehydratase (ALA-D) activity in fish blood.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)This document describes a colorimetric method to quantify the enzyme δ-aminolevulinic acid dehydratase (ALA-D) in fish blood. ALA-D is an enzyme in the heme synthesis pathway. The activity of the enzyme is inhibited by ... -
Biological effects of contaminants: Radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA) techniques for the measurement of marine fish vitellogenins.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2002)This document describes immunochemical methods to quantify the egg-yolk precursor protein vitellogenin in fish plasma. Vitellogenin is normally produced by the liver of mature female fish in response to 17β-oestradiol (E2) ... -
Biological effects of contaminants: Sediment bioassay using the polychaete Arenicola marina.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)The method described here is a whole-sediment reworker bioassay using the polychaete Arenicola marina, a direct deposit feeder that is widely distributed in European coastal waters and on the east coast of North America. ... -
Biological effects of contaminants: the use of embryo aberrations in amphipod crustaceans for measuring effects of environmental stressors.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2008)This report describes the methodology for assessing the proportions and different types of embryo aberrations in both sediment‐dwelling and nektonic amphipods. Determination of malformed embryos is a sensitive method of ... -
Biological effects of contaminants: Use of imposex in the dogwhelk (Nucella lapillus) as a bioindicator of tributyltin pollution.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1999)This document describes a method for detecting contamination of the marine environment by tributyltin (TBT) using a sensitive neogastropod, the dogwhelk Nucella lapillus (L.), as a bioindicator. Exposure of female N. ... -
Biological effects of contaminants: use of liver pathology of the European flatfish dab (Limanda limanda L.) and flounder (Platichthys flesus L.) for monitoring.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)publication provides quality assurance guidelines for the use of liver pathology of flatfish in biological effects of contaminants monitoring programmes. Information on the sampling procedures, including macroscopic ... -
Biological monitoring: General guidelines for quality assurance.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)These guidelines have been prepared by the ICES/OSPAR Steering Group on Quality Assurance of Biological Measurements in the Northeast Atlantic (SGQAE), as part of its role to encourage the production of biological data of ... -
Cadmium and lead: Determination in organic matrices with electrothermal furnace atomic absorption spectrophotometry.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1987)Experience has shown that atomic absorption analyses of lead and cadmium with pulsed-type graphite furnaces such as the Massmann design (Massmann, 1968) often are subject to various kinds of s ... -
Cadmium in marine sediments: Determination by graphite furnace atomic absorption spectroscopy.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1987)Cadmium is one of the most important toxic elements to be determined in environmental samples. Cd has proved, however, to be a difficult element to determine with good precision and relative ... -
