Pyrethroids
Pyrethroids
Pyrethroids (pronunciation: /pɪˈriːθrɔɪdz/) are a class of synthetic chemical compounds that are often used in insecticides. They are designed to mimic the insecticidal properties of the natural compound pyrethrin which is found in the flowers of Chrysanthemums.
Etymology
The term "pyrethroid" is derived from Chrysanthemums (genus Pyrethrum), the plant from which pyrethrin is extracted, and the suffix "-oid", meaning "like" or "similar to".
Types of Pyrethroids
There are several types of pyrethroids, including:
Each of these has a slightly different chemical structure, but they all work in a similar way to disrupt the nervous system of insects.
Uses
Pyrethroids are used in a variety of settings, including:
- Agriculture: They are used to protect crops from pests.
- Public health: They are used in mosquito control programs.
- Household: They are used in products like bug sprays and pet shampoos.
Health Effects
Exposure to pyrethroids can cause a variety of health effects in humans, including:
Long-term exposure can lead to more serious health problems, such as neurological damage.
Environmental Impact
Pyrethroids are not very soluble in water and tend to bind strongly to soil particles. This means they can persist in the environment for a long time. They are toxic to many types of aquatic life, including fish and insects.
