TOXICITY OVERVIEW
Most often toxicologists use Lethal Dose and Lethal Concentration to gauge the toxicity of most chemicals; evaluated on many kinds of animals but most often testing is done with rats and mice. The LD50 or LC50 is one way to measure the short-term poisoning potential (acute toxicity) of a material.

It is usually expressed as the amount of chemical administered (e.g., milligrams) per 100 grams (for smaller animals) or per kilogram (for bigger test subjects) of the body weight of the test animal. The LD50 can be found for any route of entry or administration but dermal (applied to the skin) and oral (given by mouth) administration methods are the most common.

Gosselin, Smith and Hodge Scale
Probable Oral Lethal Dose (Human)
Toxicity Rating or Class Dose For 70-kg Person (150 lbs)
6 Super Toxic Less than 5 mg/kg 1 grain (a taste - less than 7 drops)
5 Extremely Toxic 5-50 mg/kg 4 ml (between 7 drops and 1 tsp)
4 Very Toxic 50-500 mg/kg 30 ml (between 1 tsp and 1 fl ounce)
3 Moderately Toxic 0.5-5 g/kg 30-600 ml (between 1 fl oz and 1 pint)
2 Slightly Toxic 5-15 g/kg 600-1200 ml (between 1 pint to 1 quart)
1 Practically Non-Toxic Above 15 g/kg More than 1200 ml (more than 1 quart)

Please see the scale on toxicity tabulated by Gosselin, Smith and Hodge.

Some of the widely used insecticides/Termicides include pyrethroids based insecticides. Pyrethroids include a wide range of compounds the most commonly used being Permethrin, Deltamethrin, Bifenthrin, Cypermethrin, Resmethrin and Sumithrin. Apart from these insecticides based on Chlorpyrifos and Dieldrin are also present in the market. These insecticides also have a host of problems associated with them which can be summarized here
