The physical effects of freshly spilled crude oil are all too obvious. 2018-09-28 · Alcohol’s impact on your body starts from the moment you take your first sip.

Interactive toxic effects

The interactive effects were mostly antagonistic or additive, while in few cases (interactive effects of metalaxyl-M and copper on V. fischeri) a synergistic mode of action was observed for some concentration combinations. Experiments showed that interactive effects of chemicals may vary depending on the test species used as well as on the chemicals and their respective concentrations. In the plain of Thessaloniki, in Northern Greece, significant quantities of these agrochemicals have been found in water resources and soil. The three agrochemicals have a different mode of action and it is not known whether the 357 A.

Abstract : The effects of three common agrochemicals, lindane, methyl parathion and atrazine, on crustaceanDaphnia magna, algaSelenastrum capricornutumand marine bacteriumVibrio fischeriwere investigated in this study. The toxic and interactive toxic effects of two agrochemicals (fosthiazate and metalaxyl-M) and copper were investigated in this study on the photobacterium Vibrio fischeri. The toxicities of all tested compounds were generally comparable.
