Heptachlor facts for kids
Heptachlor is a man-made chemical that was once widely used to kill insects. It is known as an insecticide. People used it to get rid of pests like ants and termites. It was also used to control certain types of mosquitoes, like the ones that can spread malaria.
Heptachlor is a very strong chemical. It can stay in the environment for many years, even decades. Because it is so harmful and lasts so long, it is now on a special list of dangerous chemicals. This list is part of an international agreement called the Stockholm Convention on Persistent Organic Pollutants. This agreement helps countries work together to ban or limit the use of chemicals that harm people and the planet.

What is Heptachlor?
Heptachlor is a type of chemical called an organochloride. It was made in factories using a special chemical process called the Diels–Alder reaction. This chemical was often sold as a powder. Its main job was to kill insects that were considered pests.
How Was Heptachlor Used?
For many years, heptachlor was a popular choice for pest control.
- It helped protect homes from termites, which can cause a lot of damage to buildings.
- It was used to kill ants in gardens and around houses.
- Farmers sometimes used it as a general pesticide to protect their crops from various insects.
- In some places, it was sprayed to control mosquitoes, especially those that carry diseases like malaria.
Why Is Heptachlor Dangerous?
Even though heptachlor was good at killing insects, it is very harmful to humans and animals.
Effects on People
If people are exposed to heptachlor, it can make them sick.
- It can damage the liver, which is an important organ that helps clean the body.
- It can also harm the central nervous system, which includes the brain and nerves. This can affect how a person thinks, moves, and feels.
- Scientists also believe that heptachlor might increase the risk of cancer in people.
Effects on the Environment
One of the biggest problems with heptachlor is that it does not break down easily.
- It can stay in the soil and water for a very long time.
- This means it can pollute the environment and harm wildlife.
- Animals that eat plants or other animals exposed to heptachlor can also get sick.
- Because it lasts so long, it can travel far from where it was first used, spreading its harmful effects.
Banning Harmful Chemicals
Because heptachlor is so dangerous and stays in the environment for so long, many countries have now banned or strictly limited its use. The Stockholm Convention on Persistent Organic Pollutants is a global treaty that aims to eliminate or restrict the production and use of such harmful chemicals. Heptachlor is one of the chemicals listed under this important agreement. This helps protect people and the planet from long-lasting pollution.
