In absence of alga, up to 33% of fenvalerate added to glass containers was adsorbed to container walls in 48 h Insufficient to produce 50% growth inhibition in 96 h 2... 

With respect to NP, the lowest EC50 values for microalgae were again observed for marine organisms. The EC50 for Thalassiosira pseudonana to NP is 27 p.g L-1 which is significantly lower than the EC50 values for...

Although each of the ten materials proposed as solid reference materials provides clear benefits (each represents a unique matrix), the following subset was considered the highest priority reference materials based on Thalassiosira pseudonana cells (providing an opal matrix), on Emiliania huxleyi (providing a carbonate matrix), and on the three open-ocean sedi-...

Several studies have also been conducted to explore interactions between urea and uptake of other N substrates. In N sufficient cultures of the diatom Thalassiosira pseudonana and T. weissflogii (growing in NOs replete media) the addition of urea partiaUy inhibited NOs uptake (Lomas, 2004b Price and Harrison, 1988a) and urea additions of 5 pM resulted in 28% reduction of NOs uptake by Micromonas pusilla (Cochlan and Harrison, 1991a). However, for T. weissflogii, the reduction in...
