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 ... -
Trace metals in sea water: Sampling and storage methods.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1987)Sampling procedures for dissolved trace metals in sea water have progressed to the extent that it is now possible to describe reliable methods for the collection, preservation, and storage of ... -
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 ... -
Control procedures: Good laboratory practice and quality assurance.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1987)Good Laboratory Practice (GLP) is one of the manifestations of the increased attention being paid to quality control measures in general. It provides a framework designed to bring the quality ... -
Primary production: Guidlines for measurement by 14C incorporation.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1987)In the years intervening between the preparation and publication of this do- cument, at least two other manuals for use in making primary production de- terminations have been introduced (Nie ... -
Lipophilic organic material: An apparatus for extracting solids used for their concentration from sea water.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1987)Lipophilic organic substances, whether man-made, mobilized by human activities, or of recent natural origin, are usually dissolved in sea water at such minute concentrations that the chemical c ... -
Organic halogens: Determination in marine media of adsorbable, volatile, or extractable compound totals.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1990)The environmental impact of the release of halogenated organic compounds to the sea has become of increasing interest during recent decades. Most compounds in this group are xenobiotic of ori ... -
Soft bottom macrofauna: Collection and treatment of samples.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1990)The aim of these recommendations 1 is to standardize the methods used by different scientists for long-term benthos surveys, in order to increase the comparability of results for different ar ... -
Sediments and suspended particulate matter: Total and partial methods of digestion.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1990)In order to determine the major and trace metal concentrations of marine sediments and suspended particulate matter by wet chemical methods, it is necessary to dissolve all or part of the s ... -
Suspended particulate matter: Collection methods for gravimetric and trace metal analysis.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1990)Filtration is the most commonly used method for separating the dissolved and particulate fractions of seawater samples. A wide variety of filter types with different pore sizes has been used fo ... -
Hydrocarbons: Review of methods for analysis in sea water, biota, and sediments.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1991)The overview presented in the following paragraphs is not a collection of analytical procedures in the sense of a 'cookbook'. It is intended as an introduction to the subject and a collecti ... -
Biological effects of contaminants: Oyster (Crassostrea gigas) embryo bioassay.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1991)The oyster embryo bioassay was initially developed by Woelke (1972). The Ministry of Agriculture, Fisheries and Food (MAFF) in the UK have modified the method to improve the accuracy of the ... -
Benthic communities: Use in monitoring point-source discharges.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1991)The response to a request from the ICES Advisory Committee on Marine Pollution (ACMP) for advice on this topic has been structured along the following lines: Section A - a general review of benthic studies in relation ... -
Temporal trend monitoring: Introduction to the study of contaminant levels in marine biota.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1991)The study of contaminants in marine species, sediments, and sea water has been of interest to the International Council for the Exploration of the Sea (ICES) since the early 1970s. The inve ... -
Temporal trend monitoring: Contaminant levels in tissues of Atlantic cod.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1991)The study of trends in trace contaminant concentrations in marine species has been of interest to the International Council for the Exploration of the Sea (ICES) since the early 1970s. The ... -
Biological effects of contaminants: Microplate method for measurement of ethoxyresorufin-O-deethylase (EROD) in fish.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1991)Interest in the use of mixed function oxidase (MFa) as a monitoring tool for measuring the effects of pollntants derives from basic research carried out over the past twenty years (see revi ... -
Nutrients: Practical notes on their determination in sea water.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1996)These notes are aimed primarily at the freshwater chemist beginning to conduct analyses of nutrients in saline waters, but they will also be useful to the complete newcomer to the applicatio ... -
Contaminants in marine organisms: Pooling strategies for monitoring mean concentrations.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1996)Samples of marine organisms collected for contaminant monitoring are often pooled before being chemically analysed. The main reasons for pooling samples are: 1) to obtain a sufficient quantity ... -
Common diseases and parasites of fish in the North Atlantic: Training guide for identification.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1996)During the past 20 years, there has been an increasing number of field surveys investigating the occurrence and distribution of fish diseases as a tool for monitoring the effects of environme ... -
