Accumulation and excretion of diazinon, fenthion and fenitrothion by killifish: Comparison of individual and mixed pesticides

Estresse de transporte em cascudos amazônicos ornamentais Cochliodon sp. (L145) e Hypostomus sp. (L28) (LORICARIIDAE)

“…Parte deste material incorpora-se às plantas e ao solo e grande parte é transportada para os rios pelas chuvas. Os efeitos do uso de pesticidas constituem um problema reconhecido mundialmente e agravado pela utilização inadequada dos mesmos (TSUDA et al, 1995;WILSON & TISDELL, 2001). O uso de pesticidas na agricultura pode causar problemas de intoxicação em trabalhadores rurais que manipulam e aplicam estes produtos de alta toxicidade.…”

Evaluation of Toxicity in Silver Catfish

“…Insecticides are toxic and were designed to repel or kill unwanted organisms and when used for their different purposes they may be brought to water bodies killing or influencing the lives of aquatic organisms (El Sayed et al, 2007). The effects of the use of insecticides are recognized worldwide and compounded by their improper use (Tsuda et al, 1995;Wilson;Tisdell, 2001). …”

“…It is well proven that these chemicals are toxic to aquatic arthropods, bees and fish (Santos et al, 2007). The effects of the use of pesticides are recognized worldwide and aggravated by misuse since part of this material is accumulated in plants and soil and much of it is transported to the rivers by rain (Tsuda et al, 1995;Wilson;Tisdell, 2001). …”

Bioconcentration of Pesticides in Fish from Rivers and Lakes

“…3 for diazinon (Allison & Hermanutz, 1977;Goodman et al, 1979;Kanazawa, 1975;1978;1981;1983;Keizer et al, 1991;Nihon Kagaku-busshitsu Anzen-Jyohou Center, 1992;Seguchi & Asaka, 1981;Sancho et al, 1992;Tsuda et al, 1989a;1995;1997b;1997c), Fig. 4 for fenitrothion (De Bruijn, & Hermens, 1991;Escartin & Porte, 1996;Fisher, 1985;Kanazawa, 1975;1981;1983;1987;Lockhart et al, 1983;Miyamoto et al, 1979;Nihon Kagaku-busshitsu AnzenJyohou Center, 1992;Sancho et al, 1994;Takimoto et al, 1984;1987;Tsuda et al, 1989a;1995;1997b;1997c), Fig. 5 for malathion (Tsuda et al, 1989a;1997b) and fenthion (De Bruijn & Hermens, 1991;Tsuda et al, 1992b;1995;1996b;1997c).…”

“…4 for fenitrothion (De Bruijn, & Hermens, 1991;Escartin & Porte, 1996;Fisher, 1985;Kanazawa, 1975;1981;1983;1987;Lockhart et al, 1983;Miyamoto et al, 1979;Nihon Kagaku-busshitsu AnzenJyohou Center, 1992;Sancho et al, 1994;Takimoto et al, 1984;1987;Tsuda et al, 1989a;1995;1997b;1997c), Fig. 5 for malathion (Tsuda et al, 1989a;1997b) and fenthion (De Bruijn & Hermens, 1991;Tsuda et al, 1992b;1995;1996b;1997c). The average BCF value of each insecticide was 100 (n=12) for diazinon, 170 (n=10) for fenitrothion, 20 (n=2) for malathion and 340 (n=6) for fenthion.…”
