Poisonous Substances of Delayed Action

Delayed release agents are hazardous substances that can cause serious consequences to human health and the environment. They differ from ordinary poisons in that their clinical signs of damage appear after a latent period lasting several tens of minutes or more.

Delayed-acting toxic substances can be used as chemical weapons, but can also cause accidents at work or at home. These substances can enter the human body through the respiratory tract, skin or digestive tract.

To determine delayed-acting toxic substances, special analytical methods are required. These methods include chemical, biochemical and physical methods that can be used to detect and identify these substances.

Clinical manifestations of delayed-action poisoning can be different and depend on the type of toxic substance, its dose and route of administration. These manifestations may include headache, nausea, vomiting, diarrhea, cardiac and respiratory problems, and other symptoms.

Some of the most well-known slow-acting chemicals include organophosphates, which are used as insecticides and chemical weapons, as well as pesticides, herbicides, fungicides and other chemicals used in agriculture and industry.

To prevent poisoning by delayed-acting toxic substances, it is necessary to follow the rules of labor protection and personal hygiene, use personal protective equipment, and also be prepared to act in the event of an accident. If you suspect poisoning with delayed-acting toxic substances, you should immediately seek medical help.

In general, delayed-release toxicants pose a serious threat to human health and the environment. Therefore, it is necessary to take measures to prevent their use and distribution, as well as ensure safety when working with these substances.



Chemical agents (CA) are chemical compounds that are used as weapons. They can be used to destroy manpower, equipment and other objects. One of the types of chemical agents is slow-acting toxic substances.

Examples of toxic substances of this type are phosgene, and
