i read that Synthetic Pyrethroids are referred to as the "New Age Insecticides". Can anyone explain what are the some of the major chemical components of these insecticides?

Looks like homework to me...did you try googling ?

well, not really...tetramethrin is a common example of a pyrethroid, and it has been around for quite some time.

in a nutshell: they are considered "new" because they are more specific to insects (and therefore, in theory, safer). they don't exhibit as much acetylcholine esterase activity until they are metabolized by the insect in a way that mammals cannot.
 

1. What are the main chemical components found in insecticides?

Insecticides can contain a variety of chemical components, but some of the most common ones include organophosphates, carbamates, pyrethroids, and neonicotinoids. These chemicals work by targeting the nervous system of insects, causing paralysis and eventually death.

2. How do chemical components in insecticides affect the environment?

The impact of insecticide chemicals on the environment varies depending on the specific chemical used and the amount applied. Some chemicals can persist in the environment and may have harmful effects on non-target organisms, including beneficial insects and other wildlife. Additionally, overuse or misuse of insecticides can lead to the development of insect resistance, making them less effective over time.

3. Are there any potential health risks associated with exposure to chemical components in insecticides?

Yes, there can be potential health risks associated with exposure to insecticides. Some of the most common adverse effects include skin and eye irritation, respiratory problems, and in severe cases, neurological damage. It is essential to follow safety guidelines and use protective gear when handling insecticides.

4. Can chemical components in insecticides harm humans and pets?

Yes, chemical components in insecticides can harm humans and pets if not used properly. It is crucial to read and follow the instructions on the label carefully, wear protective gear, and keep children and pets away from treated areas. If accidental exposure occurs, seek medical attention immediately.

5. How are the levels of chemical components in insecticides regulated?

In the United States, the Environmental Protection Agency (EPA) is responsible for regulating the levels of chemical components in insecticides. They review and approve all insecticide products before they can be sold and set maximum residue limits for food products to ensure they are safe for consumption. Additionally, individual states may have their own regulations and restrictions on the use of insecticides.
