Activated carbon and pesticides
A higher concentration of activated carbon will neutralize the pesticide malathion and flies will be able to survive, even though they are exposed to the pesticide.
Activated carbon is an extremely porous carbon that has a very large surface area. A single gram of activated carbon has over 500 square millimeters of surface area. The large surface area is made available for the carbon to absorb and react with other chemicals. Activated carbon is also known as activated charcoal. It is usually made from charcoal. Activated carbon is very useful in the removal of pollutants from water and air. They are used in air purification, water filtration, cleaning spills and remediation of ground water. Activated carbon is also used in the treatment of poisoning and overdose from oral medication.
Malathion is a common agricultural pesticide. It is used in farms, recreational areas, residential landscape and public parks. Malathion is found to be useful in pest control applications and is used to eradicate flies and mosquitoes. Malathion is normally mixed with diesel fuel and used to fog areas that are known to be infested with mosquitoes and other pests. Malathion is also used in low doses for treating body and head lice.
Ensure that safety masks, goggles and gloves are worn at all times when handling the Malathion and the flies. Malathion is extremely toxic and should be handled properly, in a controlled laboratory under the supervision of your science teacher.
