Chemosphere, 2006. Loriano Ballarin Irgarol stock solutions were made in acetone at concentrations of 2.38, 1.19, and 0.59 mM. Irgarol water solutions were made by adding 10 ml stock solution to 10 liters of deionized water. Equal amounts of acetone and deionized water were added to the untreated micro-cosm.
De flesta färger hade det gemensamt att koppar kombinerats med något bekämpningsmedel från jordbruksområdet. Medel mot svamp och ogräs på land användes nu i havsmiljön för att hålla skroven rena. Cookies help us deliver our services.
16 Aug 2016 Assays performed on 25 mL of ultra-pure water sample fortified at 0.6 µg/L levels of irgarol yielded recoveries of 74.5 ± 8.6%, under optimized
It is mainly used as active ingredient in antifouling coatings for hulls and underwater constructions. Since the 1980s Irgarol has increasingly been used as substitute of the antifouling active ingredient Tributyl tin (TBT) which is banned in the The impact of Irgarol was investigated in the phytoplankton species Thalassiosira weissflogii, Emiliania huxleyi, Tetraselmis sp. and Fibrocapsa japonica. EC(50) concentrations for growth, effective quantum yield of PSII and viability were calculated from dose response relationships established during 72 h exposures to six Irgarol concentrations.

Moreover, there was a very high diversity in the psbA gene sequences in the periphyton, and the composition of psbA and D1 fragments within the communities was dramatically altered by increased Irgarol exposure.
