Degradation of 1-naphthol in sea water

Abstract

97331 to the exit side of the gas trap and an air pump to the aeration frit, with valves on both the vacuum and air pump lines to adjust the pressure in the tanks to atmospheric pressure.

Distribution and persistence of carbaryl in some terrestrial and aquatic components of a forest environment

“…However, the present value differed considerably from the ones (1.7 to 6.0 d) reported by Eichelberger and Lichtenberg (1971), Osman and Belal (1980) and Stanley and Trial (1980). In addition to dilution, light and temperature (Karinen et al, 1967;Lamberton and Claeys;1970), translocation to other matrixes such as sediment (Oloffs et al, 1972(Oloffs et al, , 1973Szeto et al, 1979), uptake by aquatic invertebrates (Courtemanch and Gibbs, 1978;Gibbs et al, 1984) and fish (Marancik, 1976;Hulbert, 1978;Haines 1981), microbial degradation (Caro et al 1974;Liu et al, 1981) also would have played an important role in residue dissipation. Minute but quantifiable amounts of carbaryl were detected in water up to 10 d postspray.…”

Auto-remediation of surface waters by solar-light: Photolysis of 1-naphthol, and two herbicides in pure and synthetic waters

“…In accordance, 1-naphthol was reported to be rapidly photodegraded (t 1/2 less than 2 h) in artificial sunlight in sea water or in pH 7 buffered water [22,23]. In sea water containing mud, t 1/2 was reported to be longer (around 5 days) but in these conditions adsorption of 1-naphthol to the sediments should occur, slowing down the photodegradation process [24].…”

Carbaryl: A Literature Review

“…Other metabolites were isolated, but were not identified. LAMBERTON and CLAEYS (1970) studied the effect of sea water and mud upon degradation of radiolabeled I-naphthol. In aquarium tanks with sea water alone, mieroorganisms were responsible for 14C02 production, and exposure to light-enhanced mierobial action.…”
