Abstract
Toxic effects of the pyrethroid pesticide deltamethrin and water-borne fluoride, alone and in combination, on free radical mediated parameters are reported in rats. Twenty-four healthy adult Wistar rats of both sexes were divided into 4 groups with 6 rats in each group. Group I receiving no treatment served as the control. Group II and group III were orally administered deltamethrin (1/100 of LD50) and 20-ppm fluoride in their drinking water, respectively, for 28 days. An additional group IV was co-administered deltamethrin and fluoride at the same dosages as groups II and III. Enhanced oxidative stress was observed as shown by significantly increased lipid peroxidation and alterations in antioxidant parameters, especially in the fluoride- deltamethrin co-exposed group IV.
NOTE FROM FAN: Deltamethrin is a brominated pyrethroid insecticide. The specific foods that this pesticide is approved for in the U.S. are here.

Effect of deltamethrin and fluoride co-exposure on the brain antioxidant status and cholinesterase activity in Wistar rats
The study evaluated the effect of commercial preparation of deltamethrin, Butox®, and fluoride (F-) co-exposure on the brain antioxidant status and cholinesterase activity in rats. Group A was untreated. Group B was gavaged Butox®, providing deltamethrin at the dose rate of 1.28 mg per kg body weight per day. Group

Sex-specific effects of fluoride and lead exposures on histology, antioxidant physiology, and immune system in the liver of zebrafish (Danio rerio).
Fluoride and Pb are both toxic to organisms; however, their combination effects and the corresponding toxic mechanisms remain unclear. In this study, male and female zebrafish (1:1) were evaluated to understand the effects of F and Pb alone and combined on growth, tissue microstructure, oxidative stress, and immune system functions

Antioxidant status in oral subchronic toxicity of fipronil and fluoride co-exposure in buffalo calves
The effects of fipronil and fluoride co-exposure were investigated on antioxidant status of buffalo calves. A total of 24 healthy male buffalo calves divided into 4 groups were treated for 98 consecutive days. Group I, receiving no treatment, served as the control. Animals of groups II and III were orally

Arsenic and fluoride co-exposure through drinking water and their impacts on intelligence and oxidative stress among rural school-aged children of Lahore and Kasur districts, Pakistan.
Arsenic (As), and fluoride (F-) are potent contaminants with established carcinogenic and non-carcinogenic impacts on the exposed populations globally. Despite elevated groundwater As and F- levels being reported from various regions of Pakistan no biomonitoring study has been reported yet to address the co-exposure impact of As and F- among

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure
