Organo-arsenic has been isolated from sole, lemon sole, flounder, dab, crab and shrimps by extraction or ion-exchange in combination with thin-layer chromatography. An alkaline digestion of the samples, followed by a reduction with sodiumborohydride leads to the formation of trimethylarsine. The behaviour of the organo-arsenic compound was very...

A high dietary intake of antioxidants ascorbic acid, tocopherol and beta-carotene and 1 or 2 servings of fish per week is associated with a lower risk of coronary heart diseases, but the 'evidence' for a preventive effect still has not been produced. A raised homocysteine level can be lowered with folate, possibly in combination with pyridoxine...

Impact pile driving is a method used to install piles for marine and inland water construction projects using high-energy impact hammers. The installation of hollow steel piles in this manner can produce extremely high sound levels in the surrounding waters (as well as in the air). Given the large-scale development of off€shore wind in European...

Objective: To measure the bioavailability of selenium from cooked and raw fish in humans by estimating and comparing apparent absorption and retention of selenium in biosynthetically labelled fish with labelled selenate and biosynthetically labelled selenium in brewers yeast. Design: The intervention study was a parallel, randomised, reference...

The ecotoxicity of lactic acid, its alkyl esters and selected metal salts was studied experimentally with the micro alga Selenastrum capricornutum, the crustacean Daphnia magna and the fish species Brachydanio rerio and Pimephales promelas. In addition, the biodegradation of lactate esters was also studied. The aim of the study was to provide...

Purification of (+)-tabun was accomplished by treatment with electric eel acetylcholinesterase (AChE) in order to bind contaminating (-)-tabun, the more potent enantiomer with respect of AChE inhibition. Electric eel AChE inhibited with (-)-tabun and with purified (+)-tabun show similar properties in reactivation reactions with oximes (pH 7.5,...

Sexually mature male common carp (Cyprinus carpio) were exposed for a 3-month period to sublethal concentrations of 4-tert-pentylphenol (TPP) and to 17β-estradiol (E2) during spermatogenesis. This was part of a broad research programme investigating the effects of TPP on the life stages of the carp which might prove susceptible to endocrine...

Prostate cancer risk in relation to consumption of animal products, and intake of calcium and protein was investigated in the Netherlands Cohort Study. At baseline in 1986, 58,279 men aged 55-69 years completed a self-administered 150-item food frequency questionnaire and a questionnaire on other risk factors for cancer. After 6.3 years of...

Between January 1999 and December 2001, the European Community project COMPREHEND was performed. The overall aim of COMPREHEND was to assess endocrine disruption in the aquatic environment in Europe, consequent to effluent discharge, with emphasis on estrogenic activity. COMPREHEND demonstrated the widespread occurrence of estrogenic effluents...

The underwater sound produced during construction of the Port of Rotterdam harbor extension (Maasvlakte 2) was measured, with emphasis on the contribution of the trailing suction hopper dredgers during their various activities: dredging, transport, and discharge of sediment. Measured source levels of the dredgers, estimated source levels of...

Marinated herring from the Baltic Sea was found to have an offensive odor and taste described as iodine-like and phenolic. Fat isolated from herring was found to contain this taint. The volatiles were isolated from the fat, using a molecular distillation and were subsequently fractionated by gas chromatography. A fraction containing the taint...

Effects of noise disturbance to fish populations may be predicted by using the four steps in the population consequences of acoustic disturbance (PCAD) model, with small scale exposure experiments as input. We have used the results from experimental studies on mortality and behavior of juvenile and adult herring exposed to naval sonar as input...

This report summarises the outcome of an international research cruise in Norwegian waters (Vestfjorden) in November 2006. The objectives of the trial were to study impacts of military low frequency - (LFAS 1-2 kHz) and mid frequency - (MFAS 6-7 kHz) active sonars on killer whales and herring. In addition the capability of active and passive...
