EXTOXNET PIP - BENOMYL
... dispersible granules. Toxicological Effects: Acute toxicity: Benomyl is of such a low acute toxicity to mammals, it has been impossible or impractical ... study in rats, the testes were the most affected sites at relatively low doses of about 15 mg/kg/day. Male rats had ... The effects last for up to 20 weeks [10]. Benomyl is relatively nontoxic to bees [2]. Environmental Fate: Breakdown in soil and ...

... livers [8]. Reproductive effects: A study of male workers exposed to low air levels of EDB at four separate manufacturing sites showed no ... between 9.3 to 10.2, suggesting that it has a low potential for bioaccumulation [180]. Effects on other organisms: No data are ... about 5 days in lake water [182,184]. Binding to sediment is relatively low. EDB decomposes in the presence of heat and/or light and ...

EXTOXNET PIP - HEPTACHLOR
... ), decreased viablility of offspring was observed [57]. In one study, rats born to mothers fed relatively low doses of heptachlor showed a tendency to develop cataracts shortly after their eyes opened, but ... [15] and should not be highly mobile [57,58]. Over their long residence times, even low mobility may result in appreciable movement and so heptachlor and its metabolite (heptachlor epoxide) may ...

Risk Characterization
... the RfD, which includes a safety factor, the exposure is considered relatively 'safe'. If it is higher than the RfD and is approaching ... NOEL EXPOSURE A MOE over 10, after extrapolation to humans, is considered low risk. This means that the No Effects Level is a lot ... , we can state that the probability can range from being negligibly low at low dose ranges or unacceptably high at high dose ranges. So, ...

EXTOXNET PIP - 4-AMINOPYRIDINE
... on other organisms: Endangered species may be adversely affected by 4-aminopyridine [167]. There is low or nonexistent potential for secondary poisoning in animals such as cats, dogs, or birds of ... soil increases with greater amounts of organic matter [167]. Studies indicate that 4-aminopyridine is relatively immobile in soils. It is not expected to be present in groundwater as a result ...

EXTOXNET PIP - MCPA
... humans from very high acute exposure could include slurred speech, twitching, jerking and spasms, drooling, low blood pressure, and unconsciousness [1]. Chronic toxicity: Dietary levels of approximately 50 mg/kg/ ... [12]. MCPA and its formulations show little affinity for soil. Breakdown in water: It is relatively stable to light breakdown [5], but can be rapidly browken down by microorganisms. In ...
