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 C

Cardiovascular dysfunction and oxidative stress following human contamination by fluoride along with environmental xenobiotics (Cd & Pb) in the phosphate treatment area of Togo, West Africa.
Highlights The exposure of the population is important in relation to the routes of exposure levels of pollutants. Cd, Pb and F in human blood are high in subjects living in and around the phosphate processing plant. The variation of the biochemical indicators indicating the risk of cardiovascular diseases. The

Co-exposure to non-toxic levels of cadmium and fluoride induces hepatotoxicity in rats via triggering mitochondrial oxidative damage, apoptosis, and NF-kB pathways.
Fluoride (F) and cadmium (Cd) are two common water pollutants. There is low information about their co-exposure in low doses. So, in this study, we evaluated the combination effects of non-toxic doses of F and Cd and the possible mechanism of their combined interaction. Male rats were exposed to non-toxic

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

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,

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.
