A new toxin, prorocentrolide B (1), has been isolated following bioassay-guided fractionation of a BuOH extract of the tropical dinoflagellate, Prorocentrum maculosum Faust. This compound produces a rapid toxic response in the mouse bioassay, a type

A dose of 10 ng As/100 g 74As-labeled arsenic acid was given in the diet to three groups of rainbow trout. These groups consisted of the control (maintained under identical conditions in the absence of arsenic) and two groups preexposed to 5.7 and 22

The growth of setae in post-division Chaeloceros gracilis Schutt was triphasic. Following cell separation there was an initial lag phase of about 30 min after which setae grew linearly at rates ranging from 0.20 to 0.38 μm-min−1. The growth rate w

The toxicity of arsenic and its compounds to aquatic organisms is well documented. Acute exposure has been shown to result in reduced growth or increased mortality in aquatic organisms. Acute toxicity levels have been established for several species

Chemical speciation of arsenic was examined by radioactive tracer and chromatographic techniques applied to muscle, liver, kidney, blood, bile, and urine from rainbow trout ( Salmo gairdneri ) given an oral dose of 74 As as arsenic acid. Conversion t

A pollutant accumulation model is developed which successfully predicts concentrations of PCBs and methylmercury in tissues of yellow perch (Perca flavescens) from the Ottawa River, Canada. The model is based on pollutant biokinetics coupled to fish

The kinetic relationships between pairs of simple intermediary metabolites such as glucose–glycerol and glucose – lactic acid measured with tracers in intact animals in a physiological steady state are analogous to those previously used in the st
