Home-use insecticide and Child Cognitive Development

Insecticides

I did not use any type of branded shampoo for my son so far. We sometimes use herbal shampoo once in a while. No Johnson and Johnson type nonsense at our home. No powder, no special soap, no special oil. I admit, sometimes, we had to use when travelling to relatives places.

Now, I will be more strict. This research paper says that lice shampoos and other insecticides used at home are actually hampering cognitive development of kids. And degenerate Adults’ cognitive abilities.

Didn’t we discuss many times that we have turned our home into graveyard of chemicals. And our body goes through intense stress while combating all chemicals. From floor cleaners to shampoo to antibiotics. 🙁

Impact of environmental exposure to insecticides on the cognitive development of 6 year old children

Pyrethroids constitute a family of insecticides widely used in a variety of sectors: agriculture (various crops), veterinary (antiparasitics) and domestic (lice shampoo, mosquito products). Their mode of action involves blocking neurotransmission in insects, leading to paralysis. Because of their efficacy and relative safety for humans and mammals, they have replaced older compounds (organochorides, organophosphates, carbamate) considered more toxic.

Exposure of children to pyrethroids is common. It is different to adult exposure, due to the closer proximity of children to ground-level dust (which stores pollutants), more frequent hand-to-mouth contact, lice shampoos, etc. In children, pyrethroids are mainly absorbed via the digestive system, but are also absorbed through the skin. They are rapidly metabolised in the liver, and mainly eliminated in the urine as metabolites within 48 hours.

Given these elements and the mode of action (neurotoxicity) of pyrethroid insecticides, the researchers proposed the hypothesis of a possible effect of these contaminants on the nervous system and its development in children.
