Symptoms of organophosphorus pesticide poisoning: Organophosphorus pesticides are a class of pesticides that can cause more serious poisoning accidents than other types of pesticides, and their cause of poisoning is the inhibition of cholinesterase in the body, which affects the transmission of nerve impulses in the human body. These compounds may be retained in the intestines or body fat and then slowly absorbed or released. Therefore, the onset of symptoms may be delayed, or symptoms may recur during treatment.
Symptoms of organophosphorus pesticide poisoning usually appear between 1/2 and 24 hours after exposure. The first symptoms of poisoning are feeling unwell, nausea, headache, generalised weakness and fatigue. They then progress to drooling (excessive salivation) and profuse sweating, vomiting, abdominal clonus, diarrhoea pupillary dilation, blurred vision, muscle twitching, spontaneous contractions, hand tremors, and frothy breathing, and the patient may have paroxysmal spasms and go into a coma. Severe cases may lead to death; mild ones recover within a month, usually without sequelae, sometimes secondary hypoxia may occur.
Symptoms of carbamate pesticide poisoning: The cause of carbamate pesticide poisoning and organophosphorus pesticides are the same, but also inhibit the cholinesterase enzyme in the body, thus affecting the transmission of nerve impulses in the body. However, the onset of carbamate pesticide poisoning is much faster and the recovery is much faster. When these pesticides are applied without proper protection, the patient will feel sick and stop working after a few moments. Because exposure is terminated immediately, the patient will begin to feel better, except in cases where the pesticide continues to be absorbed through contaminated clothing or skin.
Specific poisoning symptoms of carbamate pesticides begin to appear after 3 hours of continuous work, the beginning of the poisoning symptoms for the poisoned person to feel unwell and may have vomiting, nausea, headache and dizziness, fatigue and chest tightness; later the patient began to sweat and salivate a lot (drooling), blurred vision, spontaneous contraction of the muscles, convulsions, tachycardia or bradycardia, and a few people may experience paroxysmal spasms and go into a coma. Generally, complete recovery within 24 hours (except for extremely large doses of poisoning), without sequelae and residual disability.
Symptoms of organochlorine pesticide poisoning: Organochlorine pesticide poisoning is also rare because most of the organochlorine pesticides with more pronounced hazards were banned from sale many years ago. It may occur as a result of major contamination and may be of the nature of occupational exposure, accident, or intentional ingestion. Poisoning from organochlorine pesticides is caused by irritation of the central nervous system by these pesticides.
Poisoning by organochlorine pesticides usually occurs a few hours after exposure to the agent and begins with symptoms such as headache and dizziness, feelings of apprehension and worry, fear, and possibly agitation. Later there may be vomiting, weakness of the limbs, tremor of the hands, epileptiform seizures, and the patient may lose orientation in time and space, which may be followed by paroxysmal spasms. Death or recovery usually occurs within 1 to 3 days, and those who recover have no sequelae or permanent disability.
Symptoms of mould in pyrethroid pesticides: pyrethroids have been widely used in agricultural, public health and domestic insecticidal preparations since the late 1970s. They can be absorbed by a variety of routes and are highly toxic pesticides if injected, and then the compounds are quickly metabolised as they are absorbed. Therefore, poisoning occurs only after spraying without precautions, or after prolonged wearing of impregnated clothing so that there is a considerable amount of exposure throughout the body. Symptoms of poisoning in animals are non-specific. Depending on the type of pesticide poisoned, there are tremors or chorea-like movements.
Pyrethroid pesticides can cause abnormal sensation of the skin at the site of contact, especially on the forearms, face and neck. A tingling sensation is generally felt in the skin at the site of contact within a few hours after the first contact with the agent, most noticeable around the mouth and nose. This irritation is persistent and uncomfortable, but not very painful if at all, and there is no erythema or sign of irritation at the tingling site. This localised effect is due to a prolongation of the cutaneous neural response period at the affected site. The pesticide species that cause this effect vary in degree, with deltamethrin being the most severe. This local symptom disappears on its own within 24 hours after cessation of exposure to the agent (or after thorough washing), and there are no after-effects.
Symptoms of rodenticide poisoning: Poisoning by rodenticides is often the result of accidents in children or intentional or unintentional swallowing by adults, and is often ingested orally, requiring gastric lavage if ingested within a few hours. Symptoms of poisoning caused by different types of rodenticides vary greatly.
