Pyrethrins are gradually replacing organophosphates and organochlorides as the pesticides of choice as the latter compounds have been shown to have significant and persistent toxic effects to humans. They first appeared on markets in the 1900's and have been continually used since then in products such as bug bombs, building insect sprays, and ...
Chronic exposure to allethrins alters the plasma biochemical profile of humans and may have adverse health effects. [2] Bioallethrin has been shown to cause oxidative damage, cellular toxicity and necrosis of human lymphocytes studied in vitro. [3] It is highly toxic to fish and aquatic invertebrates.
In household concentrations pyrethroids are generally harmless to humans. [1] However, pyrethroids are toxic to insects such as bees, dragonflies, mayflies, gadflies, and some other invertebrates, including those that constitute the base of aquatic and terrestrial food webs. [2] Pyrethroids are toxic to aquatic organisms, especially fish. [3]
The World Health Organization published in 2004 that "Prallethrin is of low mammalian toxicity, with no evidence of carcinogenicity" and "is very toxic to bees and fish but of low toxicity to birds." [2] Prallethrin is a member of the pyrethroid class of insecticides. Pyrethroids have historically been classified into two groups, Type I and ...
Permethrin is a medication and an insecticide. [4] [5] As a medication, it is used to treat scabies and lice. [6]It is applied to the skin as a cream or lotion. [4] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them.
Pyrethrins are often sold in preparations that also contain the synthetic chemical piperonyl butoxide, which enhances the toxicity to insects and is faster acting compared with pyrethrins used alone. These formulations are known as synergized pyrethrins .
Toxic flame retardants can get into black plastic kitchenware and other items because the black plastic used to make them sometimes includes recycled electronic products that contain flame retardants.
Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers.Like most pyrethroids (MoA 3a), [1] it is highly toxic to fish and invertebrates, but it is far less toxic to humans. [2]
