Pesticides applied indoors may persist longer than they would in outdoor environments, making people more vulnerable to the risk of exposure. Permethrin is a pyrethroid insecticide used in agricultural, residential, and public health sites, and is commonly detected in indoor environments. The objectives of this study were to evaluate the persistence of permethrin indoors and to estimate the levels of possible dermal and non-dietary exposure to this insecticide. Permethrin was applied on…

Pyrethroid Exposure among Children Residing in Green versus Non-Green Multi-Family, Low-Income Housing

In adjusted models, green housing was not associated with statistically significant differences in children’s 3-PBA urinary concentrations compared to non-green housing, as well as demographic and household factors over the year.

Ozonolysis of Permethrin in the Atmosphere: Mechanism, Kinetics, and Evaluation of Toxicity.

The results show that ozonolysis products of PER are still extremely harmful to the environment and should be taken seriously, although the products have less toxicity than PER, and the quantitative structure and activity relationship is predicted.

Does Insect Aversion Lead to Increased Household Pesticide Use?

Simple Summary Domestic pesticides are commonly used for killing insect pests such as cockroaches and ants, despite the potential health risks associated with pesticide exposure, especially for young

Insight Into Microbial Applications for the Biodegradation of Pyrethroid Insecticides

This review paper aims to explore pyrethroid degrading strains, enzymes and metabolites produced by microbial strains and recommends possible solutions to minimize their environmental toxicity.

Biotechnological tools based lithospheric management of toxic Pyrethroid pesticides: a critical evaluation

A large number of PYs stay in the environment constitute serious lethal quantities and pose a serious threat to human health and the environment.



Pyrethroid concentrations and persistence following indoor application

The results show the considerable persistence of cypermethrin and beta-cyfluthrin indoors and indicate the risk of exposure to these products.

Sources and Impacts of Pesticides in Indoor Environments

Indoor contamination is one source of exposure to toxic pollutants and has been classified as a high environmental risk. Epidemiological research linked health effects including childhood leukemia

Biomonitoring of persons exposed to insecticides used in residences.

Although few children who resided with their parents in pest-protected homes have been monitored, they eliminated more biomarker than their parents on a kg body weight-day basis when absorbed dosages were derived from spot urine specimens corrected for volume by an age-specific creatinine correction.

The magnitude and distribution of cypermethrin from total release, over-the-counter foggers was studied in a test room and in residences to facilitate evaluation of regulatory exposure algorithms and

The Behaviour of Pyrethroids Indoors: A Model Study

Abstract Pest control agents containing three different formulations of the pyrethroids permethrin and deltamethrin and/or pyrethrines and the synergist piperonyl butoxide were applied in a model

Indoor pyrethroid exposure in homes with woollen textile floor coverings.

The indoor and biological monitoring data as well as the evaluation of the reported symptoms give no indication of an adverse health effect due to carpet treatment by permethrin.

Quantifying children's aggregate (dietary and residential) exposure and dose to permethrin: application and evaluation of EPA's probabilistic SHEDS-Multimedia model

For children in households using residential permethrin, the non-dietary exposure route was most important, and when all households were included, dietary exposure dominated; this exposure assessment tool can enhance human health risk assessments and inform children's health research.

Methodologies for estimating cumulative human exposures to current-use pyrethroid pesticides

Analysis of different approaches for estimating dermal exposure suggested that the approach assuming an even distribution of pesticide residue on the child's body was most reasonable, with all three methodologies providing reasonable estimates of exposure and dose.

Human exposure to indoor residential cyfluthrin residues during a structured activity program

Estimations of absorbed daily dosage of chemicals following contact with treated surfaces may be required for risk assessment and risk management and predicted ADDs based upon environmental measurements overestimated the ADDs measured by urinary excretion.
