“…A number of pyrethroids, such as permethrin, cypermethrin, deltamethrin, and esfenvalerate, have been reported to be present in house dust with detection frequency (%D) ranges from various studies of 45–100%, 5–64%, 5–17% and 5–29%, respectively (Bradman et al, 2007; Colt et al, 2004; Hwang et al, 2008; Julien et al, 2008; Morgan et al, 2007; Quirós-Alcalá et al, 2011; Rudel et al, 2003; Starr et al, 2008). Much of this data was collected before or in the same year as the federally mandated phase-out of residential uses of the organophosphate pesticides chlorpyrifos and diazinon in 2001, which subsequently caused household pyrethroid use to increase (Horton et al, 2011; USEPA, 2001, 2012; Williams et al, 2008).…”

Indoor pesticide exposure is a growing concern, particularly for pyrethroids, a commonly used class of pesticides. Pyrethroid concentrations may be especially high in homes of immigrant farm worker families, who often live in close proximity to agricultural fields and are faced with poor housing conditions, potentially causing high pest infestation and pesticide use. We investigate levels of pyrethroids in the house dust of farm worker family homes in a study of mothers and children living in Mendota, CA, within the population-based Mexican Immigration to California: Agricultural Safety and Acculturation (MICASA) Study. We present pesticide use data and levels of pyrethroid pesticides in indoor dust collected in 2009 as measured by questionnaires and a GC/MS analysis of the pyrethroids cis- and trans-permethrin, cypermethrin, deltamethrin, esfenvalerate and resmethrin in single dust samples collected from 55 households. Cis- and trans-permethrin had the highest detection frequencies at 67%, with median concentrations of 244 and 172 ng/g dust, respectively. Cypermethrin was detected in 52% of the homes and had a median concentration of 186 ng/g dust. Esfenvalerate, resmethrin and deltamethrin were detected in less than half the samples. We compared the pyrethroid concentrations found in our study to other studies looking at both rural and urban homes and daycares. Lower detection frequencies and/or lower median concentrations of cis- and trans-permethrin and cypermethrin were observed in our study as compared to those studies. However, deltamethrin, esfenvalerate and resmethrin were detected more frequently in the house dust from our study than in the other studies. Because households whose children had higher urinary pyrethroid metabolite levels were more likely to be analyzed in this study, a positive bias in our estimates of household pyrethroid levels may be expected. A positive association was observed with reported outdoor pesticide use and cypermethrin levels found in the indoor dust samples (rs = 0.28, p = 0.0450). There was also a positive association seen with summed pyrethroid levels in house dust and the results of a pesticide inventory conducted by field staff (rs = 0.32, p = 0.018), a potentially useful predictor of pesticide exposure in farm worker family homes. Further research is warranted to fully investigate the utility of such a measure.

“…Separating the DAPs into the diethyl and dimethyl metabolites provided some measure of specificity but not to the extent needed to identify the corresponding individual pesticides. Secondly, as suggested by several studies, the generation of DAPs and pyrethroid metabolites can occur naturally in the environment and in food items and juices (Lu et al, 2005), which will lead to the detection of pesticide metabolites in urine samples (Starr et al, 2008;Zhang et al, 2008). Therefore, in addition to exposures to the parental pesticides, urinary detection of pesticide metabolites in the current study could also be resulted from direct exposures to environmentally preformed pesticide metabolites (Zhang et al, 2008).…”

Analysis and evaluation of pyrethroid exposure in human population based on biological monitoring of urinary pyrethroid metabolites

The current risk assessment of human exposure to low-level pyrethroids (PYRs) is generally based on the estimation of residue intake from diets. Limited data are available on individual exposure levels in human studies, which is partly attributable to the difficulty in biological monitoring of PYR exposure. This obstacle has been overcome in recent years due to the evolution of analytical chemistry. Separation and sensitive identification and quantitation of urinary PYR metabolites are today reliably made with liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry. This article gives an overview of the biological monitoring of urinary PYR metabolites, reviews PYR metabolite levels in general populations, and discusses future research perspectives in the field of environmental health.
