The insecticide synergist piperonyl butoxide inhibits hedgehog signaling: assessing chemical risks.
The spread of chemicals, including insecticides, into the environment often raises public health concerns, as exemplified by a recent epidemiologic study associating in utero piperonyl butoxide (PBO) exposure with delayed mental development. The insecticide synergist PBO is listed among the top 10 chemicals detected in indoor dust; a systematic assessment of risks from PBO exposure, as for many...
متن کاملAcute effects of Permanone 31-66 (permethrin-piperonyl butoxide) on nontarget minnows and grass shrimp.
Immature sheepshead minnows (Cyprinodon variegatus), inland silversides (Menidia beryllina), mosquitofish (Gambusia holbrooki), and grass shrimp (Palaemonetes pugio) were exposed to the mosquito adulticide, Permanone 31-66, in a series of static toxicity tests conducted in the laboratory. At 24 h, in order of decreasing susceptibility, LC50 values were 0.843, 4.07, 5.46, and 6.04 ppb for grass ...
متن کاملPrenatal exposure to pesticide ingredient piperonyl butoxide and childhood cough in an urban cohort.
RATIONALE Previously we reported that airborne concentrations of cis-permethrin, but not trans-permethrin, measured during pregnancy in an inner city pediatric cohort was associated with cough by age 5. However, the effect of subsequent exposures to both permethrins during early childhood, and to piperonyl butoxide (PBO, a synergist for residential pyrethroid insecticides) remains to be elucida...
متن کاملEffects of piperonyl butoxide on the toxicity of the organophosphate temephos and the role of esterases in the insecticide resistance of Aedes aegypti.
INTRODUCTION The effects of piperonyl butoxide (PBO) on the toxicity of the organophosphate temephos (TE) and the role of esterases in the resistance of Aedes aegypti to this insecticide were evaluated. METHODS A. aegypti L4 larvae susceptible and resistant to TE were pre-treated with PBO solutions in acetone at concentrations of 0.125, 0.25, 0.5, 1, and 2% for 24h and subsequently exposed to...
متن کاملInduction of glutathione S-transferase activity in Triatoma infestans.
Several synthetic pesticides and allelochemicals used to treat Triatoma infestans adults by topic application showed some degree of cytosolic glutathione S-transferase (GST) induction. General inducers of detoxication systems such as phenobarbital and 3-methylcholantrene topically applied on T. infestans resulted in no GST induction. Meanwhile, general insecticide synergist such as piperonyl bu...
