“…4) were 2,5,6-trichloro-4-hydroxyisophthalonitrile and 2,5,6-trichloroisophthalonitrile. Other degradation products were identified by Sato and Tanaka (1987). They also concluded that degradation occurred via dechlorination and partial substitution (Fig.…”

“…De acordo com esses autores, a formação de ligações covalentes envolveram reações oxidativas, as quais foram mediadas por enzimas microbianas. O fato de o clorotalonil não ser dissipado em solos autoclavados (Sato & Tanaka, 1987;Katayama et al, 1991;Katayama et al, 1997) Gamble et al (2000) estudaram a cinética de formação de resíduos ligados de 14 C-clorotalonil em solos semelhantes ao RQo. Utilizando modelos diferenciais baseados na Lei de Fick, observaram que 30,5% do fungicida aplicado ficou retido no solo após 18 dias da aplicação.…”

“…O clorotalonil, entretanto, é considerado pouco persistente no ambiente, apresentando valores de meia-vida de dissipação que variam de 5 a 36 dias (Sun et al, 1985;Sato & Tanaka, 1987;Walker et al, 1988;Takagi et al, 1991;Katayama et al, 1997;Motonaga et al, 1998;van der Pas et al, 1999), reflexo da rápida transformação microbiológica e da elevada formação de resíduos ligados, resultante da alta taxa de sorção dessa molécula (Regitano et al, 2001).…”

“…Because it is a wide spectrum fungicide inhibiting the activity of SH-enzymes (Vincent and Sisler 1968), this compound has been widely used in Japan and other countries to control pathogenic fungi of crops. It can be easily degraded by many soil microorganisms (Katayama et al 1987), however, little is known about the fate of TPN in soil (Sun et al 1985;Sato and Tanaka 1987). Hereafter in this paper, this compound will be abbreviated as TPN, since this name is more popular than chlorothalonil in Japan.…”
