Symptoms of organophosphorus pesticide poisoning: Organophosphorus pesticides are a class of pesticides that are more likely to cause serious poisoning accidents than other types of pesticides. The 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 remain in the gut or in body fat and are slowly absorbed or released. The onset of symptoms of intoxication may therefore be delayed, or symptoms may recur during treatment.
Symptoms of organophosphorus pesticide poisoning generally appear between 1/2 and 24 hours after exposure. The first symptoms of poisoning are feeling unwell, nausea, headache, general weakness and fatigue. Drooling (hypersalivation) followed by profuse sweating, vomiting, abdominal clonus, diarrhea, miosis, blurred vision, muscle twitches, spontaneous contractions, hand tremors, breathing with foam, patient may have paroxysms convulsions and falls into a coma. Severe cases may lead to death; mild cases recover within a month, generally without sequelae, and sometimes secondary hypoxia may occur.
Symptoms of carbamate pesticide poisoning: The cause of carbamate pesticide poisoning is the same as that of organophosphorus pesticides. It also inhibits cholinesterase in the human body, thereby affecting the transmission of nerve impulses in the human body. But carbamate poisoning has a quick onset and a much quicker recovery. When these types of pesticides are applied without taking proper precautions, after a while you feel sick and stop working. The patient will begin to feel better because the exposure is immediately terminated, unless the pesticide continues to be absorbed through contaminated clothing or skin.
The specific poisoning symptoms of carbamate pesticides begin to appear after 3 hours of continuous work. The initial symptoms of poisoning are that the poisoned person feels unwell and may have vomiting, nausea, headache and dizziness, fatigue and chest tightness; Saliva (drool), blurred vision, spontaneous muscle contraction, convulsions, tachycardia or bradycardia, a few people may have paroxysmal convulsions and go into coma. Generally, it recovers completely within 24 hours (except those poisoned by extremely large doses), without sequelae and residual disabilities.
Symptoms of organochlorine pesticide poisoning: Organochlorine pesticide poisoning is also rare, because most organochlorine pesticides with obvious hazards have been banned from sale many years ago. It may occur as a result of significant contamination, which may be of the nature of occupational exposure, accident, or intentional ingestion. The poisoning of organochlorine pesticides is caused by the stimulation of the central nervous system by these pesticides.
The poisoning of organochlorine pesticides usually occurs several hours after contact with the agent. The initial symptoms are headache and dizziness, anxiety, fear, and possibly emotional agitation. There may be vomiting, weakness of the extremities, tremors in the hands, epileptic seizures, and the patient may lose orientation in time and space, followed by seizures. Usually die or recover within 1 to 3 days, and those who recover have no sequelae or permanent disabilities.
Mold Symptoms in Pyrethroid Pesticides: Pyrethroids have been widely used in agricultural, public health, and household insecticide formulations since the late 1970s. They can be absorbed through various routes, and if injected, they are highly toxic pesticides, and then these compounds are quickly metabolized while being absorbed. Therefore, poisoning occurs only after careless precautions are taken when spraying, or after wearing impregnated clothes for a long time, so that the whole body has a considerable amount of contact. Symptoms of animal poisoning are nonspecific. Depending on the type of pesticide poisoned, there are tremors or chorea-like movements.
Pyrethroid pesticides can cause paresthesias in the skin at the site of exposure, especially on the forearms, face and neck. Usually within a few hours after the first exposure to the drug, there is a tingling sensation on the skin at the contact site, most noticeable around the mouth and nose. The irritation was constant and uncomfortable, but not painful, with no signs of erythema or irritation at the sting site. This local effect is due to a prolonged refractory period of the cutaneous nerves in the affected area. There are differences in the degree of each pesticide species causing this effect, and deltamethrin is the most serious. This local symptom disappears within 24 hours after stopping exposure to the agent (or after thorough washing), and there is no sequelae.
Symptoms of rodenticide poisoning: Rodenticide poisoning is often caused by accidental accidents of children or intentional or unintentional swallowing by adults. It is often oral ingestion. If it is ingested within a few hours, gastric lavage is required. The symptoms of poisoning caused by different types of rodenticides vary greatly.
