What happens if you drink fungicide

By wearing a pair of unlined, chemical-resistant gloves, this type of exposure can be nearly eliminated. Acute toxicity of a pesticide refers to the chemical's ability to cause injury to a person or animal from a single exposure, generally of short duration. The harmful effects that occur from a single exposure by any route of entry are termed "acute effects.

Acute toxicity is determined by examining the dermal toxicity, inhalation toxicity, and oral toxicity of test animals.

In addition, eye and skin irritation are also examined. Acute toxicity is measured as the amount or concentration of a toxicant--the a. This measure is usually expressed as the LD 50 lethal dose 50 or the LC 50 lethal concentration LD 50 and LC 50 values are useful in comparing the toxicities of different active ingredients and different formulations containing the same active ingredient.

The lower the LD 50 or LC 50 value of a pesticide product, the greater its toxicity to humans and animals. Pesticides with a high LD 50 are the least toxic to humans if used according to the directions on the product label. The chronic toxicity of a pesticide is determined by subjecting test animals to long-term exposure to the active ingredient. Any harmful effects that occur from small doses repeated over a period of time are termed "chronic effects.

The chronic toxicity of a pesticide is more difficult than acute toxicity to determine through laboratory analysis. Products are categorized on the basis of their relative acute toxicity their LD 50 or LC 50 values.

Pesticides that are classified as highly toxic Toxicity Category I on the basis of either oral, dermal, or inhalation toxicity must have the signal words DANGER and POISON printed in red with a skull and crossbones symbol prominently displayed on the front panel of the package label. For example, exposure of a few drops of a material taken orally could be fatal to a pound person. Some pesticide products have just the signal word DANGER, which tells you nothing about the acute toxicity, just that the product can cause severe eye damage or severe skin irritation.

A teaspoon to an ounce of this material could be fatal to a pound person. An ounce or more of this material could be fatal to a pound person. Table 1 summarizes the LD 50 and LC 50 values for each route of exposure for the four toxicity categories and their associated signal word. Pesticide labels and MSDS can be obtained from retailers or manufactures. In addition, most products also have information that can be found on the Internet.

The symptoms of pesticide poisoning can range from a mild skin irritation to coma or even death. Different classes or families of chemicals cause different types of symptoms.

Individuals also vary in their sensitivity to different levels of these chemicals. Some people may show no reaction to an exposure that may cause severe illness in others.

Because of potential health concerns, pesticide users and handlers must recognize the common signs and symptoms of pesticide poisoning. The effects, or symptoms, of pesticide poisoning can be broadly defined as either topical or systemic. Dermatitis, or inflammation of the skin, is accepted as the most commonly reported topical effect associated with pesticide exposure. Some individuals tend to cough, wheeze, or sneeze when exposed to pesticide sprays. Some individuals react to the strong odor and irritating effects of petroleum distillates used as carriers in pesticide products.

One symptom is that the eyes, mucous membranes of the nose, and even the sensitive linings of the mouth and back of the throat feel raw and scratchy. This symptom usually subsides within a few minutes after a person is removed from the exposure to the irritant. However, a reaction to a pesticide product that causes someone not only to sneeze and cough but also to develop severe acute respiratory symptoms is more likely to be a true hypersensitivity or allergic reaction. Symptoms of a true allergic reaction range from reddening and itching of the eyes and skin to respiratory discomfort often resembling an asthmatic condition.

Systemic effects are quite different from topical effects. They often occur away from the original point of contact as a result of the pesticide being absorbed into and distributed throughout the body. Systemic effects often include nausea, vomiting, fatigue, headache, and intestinal disorders. In advanced poisoning cases, the individual may experience changes in heart rate, difficulty breathing, convulsions, and coma, which could lead to death.

Be alert for the early signs and symptoms of pesticide poisoning in yourself and others. These often occur immediately after exposure, but they could be delayed for up to 24 hours. If you are having symptoms but are unsure if they are pesticide related, at least notify someone in case your symptoms become worse.

But when symptoms appear after contact with pesticides, you should seek medical attention immediately. At this time, call the National Poison Center at for guidance on the proper response to your symptoms. This number will direct your call to the nearest poison center, which is staffed on a hour basis. If safe to do so, take the pesticide container to the telephone. However, if the pesticide container is contaminated, write down the product name, active ingredient s and percentage, and the EPA registration number.

The product label provides medical personnel information such as active ingredients, an antidote, and an emergency contact number for the manufacturer. If the Material Safety Data Sheet is available, take this also because it contains additional information for medical personnel.

If you must go to the hospital or doctor's office, take the entire pesticide container, including the label, with you. In order to avoid inhaling fumes or spilling the contents, make sure the container is tightly sealed and place into a plastic bag if possible.

The pesticide container should never be placed in the enclosed passenger section of your vehicle. The acute toxicity of fungicides to humans is generally considered to be low, but fungicides can be irritating to the skin and eyes.

Inhalation of spray mist or dust from these pesticides may cause throat irritation, sneezing, and coughing. Chronic exposures to lower concentrations of fungicides can cause adverse health effects. Most cases of human fungicide poisonings have been from consumption of seed grain. To prevent these types of poisonings, fungicide treatment now includes a brightly colored dye to clearly indicate that the seed has been treated. Table 2 summarizes the signs and symptoms of acute exposures to commonly used fungicides.

In general, herbicides have a low acute toxicity to humans because the physiology of plants is so different than that of humans. However, there are exceptions; many can be dermal irritants since they are often strong acids, amines, esters, and phenols. Inhalation of spray mist may cause coughing and a burning sensation in the nasal passages and chest. Prolonged inhalation sometimes causes dizziness. Ingestion will usually cause vomiting, a burning sensation in the stomach, diarrhea, and muscle twitching.

Table 3 summarizes the signs and symptoms of acute exposures to commonly used herbicides. Insecticides cause the greatest number of pesticide poisonings in the United States.

The most serious pesticide poisonings usually result from acute exposure to organophosphate and carbamate insecticides. Organophosphate insecticides include chlorpyrifos, diazinon, dimethoate, disulfoton, malathion, methyl parathion, and ethyl parathion. The carbamate compounds include carbaryl, carbofuran, methomyl, and oxamyl. Organophosphates and carbamates inhibit the enzyme cholinesterase, causing a disruption of the nervous system. All life forms with cholinesterase in their nervous system, such as insects, fish, birds, humans, and other mammals, can be poisoned by these chemicals.

To understand how the organophosphate and carbamate insecticides affect the nervous system, one needs to understand how the nervous system actually works.

The nervous system, which includes the brain, is the most complex system in the body consist- ing of millions of cells that make up a communications system within the organism. Messages or electrical impulses stimuli travel along this complex network of cells. Nerve cells or neurons do not physically touch each other; rather there is a gap or synapse between cells.

The impulses must cross or "bridge" the synapse between nerve cells in order to keep the message moving along the entire network. When an impulse reaches the synapse, the chemical acetylcholine is released to carry the message on to the next cell. Acetylcholine is the primary chemical responsible for the transmission of nerve impulses across the synapse of two neurons.

After the impulse is transmitted across the synapse, the acetylcholine is broken down by the enzyme cholinesterase. Some can cause severe burns or permanent blindness. Chemicals with these irritant or corrosive properties require extra care and special PPE. Fungicides, herbicides, and some insecticides may cause contact injuries. Manufacturers list nonlethal systemic and contact effects in addition to the signal word. Systemic and contact acute toxicity concerns are indicated by the signal word.

EPA and the manufacturer take into account both systemic and contact toxicity measures in assigning the signal word and toxicity category to a product. These are assigned on the basis of the greatest concern—be it oral, dermal, or inhalation systemic effects or skin, eye, or respiratory tract contact effects. The Globally Harmonized System GHS for classification and labeling of chemicals is an international system for hazard communication. The goal is to improve and simplify hazard communication and alert users to the need to minimize exposure and risk.

The system will identify more types of hazards than the current signal words on pesticide labels. This should result in safer transportation, handling, and use of chemicals.

This table summarizes the range of LD 50 and LC 50 values and their relationship to the different toxicity levels. Depending on their acute toxicity, pesticide products are categorized into several hazard classes. Some very low toxicity products Hazard Class IV are not required to have a signal word. The lethal toxicity may be based on oral, dermal, or inhalation exposure, depending on the exposure route that presents the greatest risk for that product.

The contact effects of these pesticides are more dangerous than the acute systemic toxicity. Contact effects are generally irritation of eyes, skin, or respiratory tract. The chronic toxicity of a pesticide is determined by subjecting test animals to long-term usually 2 years exposure to an active ingredient. The harmful effects that occur from small, repeated doses over time are termed chronic effects. Chronic effects from pesticide exposure include genetic changes, noncancerous or cancerous tumors, reproductive effects, infertility, fetal toxicity, miscarriages, birth defects, blood disorders, nerve disorders, and hormonal or endocrine-mediated diseases.

Each pesticide has its own characteristic pattern of diseases and adverse effects that it might cause. However, no single pesticide is likely to be able to cause the entire range of harmful effects.

Minimizing the likelihood of chronic effects is one of the important reasons to follow all label directions and be cautious in handling and applying pesticides. If a product causes chronic effects in laboratory animals, the manufacturer is required to include chronic toxicity warning statements on the product label. This information is also listed on the Safety Data Sheet.

The chronic toxicity of a pesticide is more difficult to determine through laboratory analysis than the acute toxicity and cannot be expressed by a single measure. Delayed effects are illnesses or injuries that do not appear immediately within 24 hours after exposure to a pesticide. They may be delayed for weeks, months, or even years. Whether you experience delayed effects depends on the pesticide, the extent and route of exposure s , and how often you were exposed.

It also tells you how to avoid exposures. Delayed effects may be caused by either an acute or a chronic exposure to a pesticide.

Humans have built-in mechanisms to reduce the risks of toxic substances and to eliminate them from the body. The liver is the primary organ that changes toxic substances to nontoxic or less-toxic forms. Its chemical breakdown processes help to make most of these substances more water-soluble so they can be eliminated. The kidneys filter water-soluble unwanted chemicals out of the blood and into the urine. Those that cannot be made water-soluble are eventually are stored in fatty deposits throughout the body and in breast milk.

Many of the pesticides in use today are more water-soluble than those used before Most are eliminated relatively quickly hours to days instead of months to years in urine. Some pesticides can cause changes, called mutations , to our DNA.

DNA is the carrier of genetic information in our bodies. Some DNA mutations do not cause any effects. Others cause serious malfunctions and may lead to various types of illnesses or other problems, such as birth defects.

Our bodies continually manufacture the enzymes we need to help detoxify pesticides and other toxic substances. Keeping your exposure low and having periods of non-exposure between applications of the same class of pesticide can reduce the chance that your body will be overwhelmed.

Symptoms can be correlated with certain groups of pesticides. For example, some fungicides irritate the skin, eyes, and mucous membranes of the respiratory system. Symptoms associated with synthetic pyrethroid insecticides include nausea, dizziness, weakness, nervousness, and eye and skin irritation.

They may also cause vomiting, headaches, diarrhea, and confusion. Get medical advice immediately for unusual or unexplained symptoms that develop within 24 hours of a pesticide exposure.

Be alert for the early symptoms of pesticide poisoning and contact local effects in yourself and others. Do not wait to call a physician until you or someone else gets dangerously ill.

It is better to be too cautious than to act too late. Take the pesticide label or EPA registration number with you to help medical personnel to treat you appropriately and quickly. The label is important because the medical professional needs to know the pesticide ingredients to determine the proper course of treatment. It is a good idea to print off extra copies of the label from the Internet. Place one copy in your service vehicle and one in your office in case of a medical emergency.

Keep in mind that symptoms commonly associated with certain pesticides are not always the result of exposure. Common illnesses e. Contact with certain plants, such as poison oak or poison ivy, may also produce skin effects like those resulting from pesticide exposure. However, it is best to take every precaution. When symptoms appear after contact with pesticides, always seek medical attention immediately. First aid is the initial effort to assist a victim while medical help is on the way. If you are alone with the victim, make sure he or she is breathing and exposure to the pesticide has stopped.

Then call for help. Protect yourself from pesticide exposure before and while giving assistance. Make sure you wear the appropriate PPE, including a respirator if indicated, before assisting someone in an enclosed area.

Administer artificial respiration if the victim is not breathing and is not vomiting. Immediate action can be a life-or-death matter in a pesticide poisoning. The product label is the primary source of information. It is very important to get the victim to a hospital, or contact for emergency response, without delay. Post all emergency numbers near telephones and in service vehicles used by pesticide handlers. Heat stress occurs when the body cannot cope with a certain level of heat.

Heat stress may affect both pesticide handlers and other workers. A person suffering from heat stress exhibits symptoms that closely resemble poisoning symptoms of some pesticides.

PPE worn during handling or early-entry activities may increase the risk of heat stress. Vests and headbands with special pockets for ice packs or other heat stress prevention devices may be worn with or beneath PPE. These will help maintain a cool body temperature. Mild forms of heat stress make people feel ill and impair their ability to do a good job. You may feel weak and get tired sooner than usual.

You may also be less alert and less able to use good judgment. Severe heat stress, also known as heatstroke, is life-threatening. Staggering, loss of consciousness or convulsions may result. Lack of sweating is a common symptom of heatstroke.

Brain damage or even death may occur if the heatstroke victim is not cooled very quickly. Sometimes victims remain highly sensitive to heat for months and cannot return to the same type of work. Act immediately to cool down if you suspect that you may be suffering from even mild heat stress.

Drink plenty of water and take breaks in the shade throughout the workday. In hot conditions, watch for symptoms of heat stress in other workers as well. These two factors determine the likelihood that harm i. Harmful effects of pesticides may occur at the area of local contact or after uptake into the body i. Pesticides can enter the body by any of four routes: through the skin dermal , eyes ocular , lungs respiratory , or mouth oral.

Some adverse effects may occur within 24 hours after a single usually large exposure acute effects. Symptoms of carbamate poisoning also are relieved by atropine but usually not by pralidoxime. Symptoms of pyrethrin poisoning resolve without treatment.
