Some polymeric marine coatings based on vinylcopolymer and linseed oil have been prepared in the laboratory and their efffect on phytoplankton standing crop was tested. the coating is prepared either from vinylcopolymer or linseed oil or a mixture of both binders with 1:1, 1:2 and 2:1 ratios in the presence or absence of a soluble resin. the coatings were applied to glass slides and tested in a sea water medium. Also, correlations between the weight of the coating film and numbers of phytoplankton species were calculated. the results showed no correlation between the weight of films of either vinylite or oil binders and the total number of all phytoplankton species, but significant correlation was found for some phytoplankton species, such as Thalassiosira decipiens. the weight of the film coating of vinylcopolymer in the presence of soluble resin with 1:1, 1:2 and 2:1 ratios is significantly correlated to the total number of phytoplankton and some other dominant species. Formulations of linseed oil and a soluble resin with 1:1, 1:2 and 2:1 ratios are correlated to the numbers of Chaetoceros affinis, Bellorochea malleus and Skeletonema costatum. |
