Responses in sediment bioassays used in the Netherlands: can observed toxicity be explained by routinely monitored priority pollutants?

Factors determining the accumulation of pentachlorophenol — a precursor of dioxins in bottom sediments of the Gulf of Gdańsk (Baltic Sea)

“…Toxicity of the collected sediments was measured by Microtox® using the Basic Solid Phase procedure, commonly applied for a sediment quality assessment (Salizzato et al 1998, Lahr et al 2003, Viganoet al 2003. The test applies a strain of marine bacteria Vibrio fisheri as a bioindicator.…”

“…The relationship between the contaminant concentration and the sediment toxicity has been recognized by many researchers, both for heavy metals and persistent organic pollutants (Salizatto et al 1998, Lahr et al 2003, Parvez et al 2006). However, there was no relationship between the PCP concentration and toxicity of sediments analyzed in this study.…”

VARIABILIDAD DEL ENSAYO ECOTOXICOLÓGICO CON Chironomus calligraphus Goeldi (DIPTERA: CHIRONOMIDAE) PARA EVALUAR CADMIO, MERCURIO Y PLOMO

“…Los organismos biológicos para ser usados como herramientas ecotoxicológicas requieren ser sencillos, prácticos, sensibles y repetibles (Iannacone et al, 1998;Alayo & Iannacone, 2002). La APHA (1989) señala como protocolos estandarizados para la realización de bioensayos de toxicidad aguda y crónica acuática a las larvas de los insectos quironómidos, principalmente Chironomus tentans Fabricius, Chironomus riparius Meigen y Chironomus plumosus (Linnaeus) (Mereggalli et al, 2002;Lahr et al, 2003;Martinez et al, 2003 (Iannacone et al, 2000;Crane et al, 2002;Sánchez & Tarazona, 2002).…”

Geostatistical methods for estimation of toxicity of marine bottom sediments based on the Gdańsk Basin area

“…The results presented as maps indicate the particularly endangered regions where further studies on the identification of chemicals responsible for the toxicity should be carried out. Considering different analytical procedures, the Basic Solid Phase Test (Azur Environmental 1998) corresponds to the toxicity of the entire sediment and has been commonly applied for marine sediments (Salizzato et al 1998, Lahr et al 2003, Vigano et al 2003, Coz et al 2008. It has also been approved as a standard government ecotoxicological bioassay in several countries like Canada, The Netherlands, France, Germany, Sweden and Spain (Keddy et al 1995, Park & Hee 2001.…”
