What is Pesticide Poisoning?
What are the Causes Pesticide Poisoning?Most common causes are:
Accidental or Suicidal Poisonings
Poisoning oneself with agricultural pesticides is a major public health problem and accounts for 1/3rd of all suicide cases globally. Stress is a major factor where most cases of intentional pesticide poisoning are noted and availability of pesticides raises the incidence.
As pesticides are used in many industries, its extensive use can lead to increased risk for pesticide illnesses. For instance, in retail stores, workers are at risk of exposure as pesticides are commercially available. In case of firefighters and police officers, they are at risk as they are the first responders to accidental cases.
Therefore, different job functions can have various exposure levels. Occupational exposures can be caused by absorption through face, hands, forearms and chest and sometimes through inhalation of sprays in closed environments like greenhouses.
This form of poisoning is caused by long-term low-level exposure. In this case, low levels of pesticide residues in food, air, soil, plants, animals, and sediment and food materials are the cause.
What are the Symptoms of Pesticide Poisoning?Poisoning may affect different body parts as below:
|Nervous||Anxiety, coma, convulsions, dizziness, headache|
|Skin||Irritation, redness/swelling, blue lips and finger nails|
|Bladder & Kidney||Excessive urination|
|Eyes, Ears, Nose, Throat||Increased salivation, small pupil size, more tears|
|Gastrointestinal||Cramps in abdomen, diarrhea, appetite loss, vomiting, nausea|
|Heart & Blood||Lowered heart rate|
Poisoning can lead to serious consequences if touched without gloves or if you do not wash hands after exposure. It can also lead to life-threatening paralysis and even death in some cases.
How do you Diagnose Pesticide Poisoning?As pesticide-related illness show similar signs and symptoms like common medical conditions, therefore, complete detailed environmental and occupational history is necessary for its accurate diagnosis. A detailed questionnaire about patient's environment and workplace can give and extent of potential pesticide poisoning.
In the case of carbamate and organophosphate poisoning, baseline cholinesterase test is required. If baseline test is done and poisoning is suspected, then the extent of the problem is identified by comparing baseline level with present cholinesterase level.
How do you Treat Pesticide Poisoning?Treatment is specific and often dependent on pesticide type or class. However, basic management techniques apply to most acute poisonings. If pesticide is encountered on the body:
Remove the person from the source of exposure to prevent further poisoning. It is also important that the person taking care of the victim should also take necessary precautions to prevent contact exposure.
On the Clothes
- Remove the clothing that pesticides are spilled on.
- Wash off the pesticide on the skin at the earliest with soap and cold water.
- If spilled into the eye, then rinse the eye with clean water for 15 minutes
If skin is burnt from pesticides:
- Keep that part of skin under running tap water
- Rinse well with cool water
- Don't remove anything stuck to the burnt part
- Restrict applying lotions or ointment
- Stop from breaking blisters and removing of loose skin
- Apply sterile dressing, if available and cover it thoroughly
- If pain persists, seek medical help.
If person is:
- Unconscious, then lay them on the side and make sure they are breathing.
- Not breathing, then do mouth to mouth breathing, but take care by keeping mask or piece of cloth or thick plastic wrap with a hole in the center as giving mouth-to-mouth may affect you as well.
- Read the label of pesticide as this will tell if person needs to be vomited or not
- Seek medical help and take along pesticide label or name with you.
- If the person can drink, then give them lots of clean water as soon as possible.
- Vomit, if the label says not to, as pesticide may contain gasoline, xylene, kerosene or other petroleum based products. Vomiting may make problems worse.
- Vomit or drink, if the person is unconscious, confused or agitated.
- If you are sure that vomiting is ok, then give the person a glass of salty water or two tablespoons of strong tasting edible plant like basil, celery or local herb, and then later on about 2 glasses of warm water.
- Ask the person to move, as this can help make him vomit sooner.
- Once vomited, activated or powdered charcoal can help absorb available poison in the stomach.
- Take the person away from the area where the pesticide has spread, especially if the area is enclosed.
- Loosen the cloth for easier breathing.
- Make him sit with head and shoulders raised.
- If unconscious: lay that person on the side and make sure that breathing is not blocked.
- If person is not breathing, do mouth-to-mouth breathing
- Seek medical help and take along pesticide name or label along with you.
Prognosis of Pesticide PoisoningRemoving the victim from the source, thorough washing of the exposed parts and shifting to a medical centre are the three most prior steps in treatment. If these steps are done without any time lapse, then the chances of survival of the victimare high.
How do you Prevent Pesticide Poisoning?
|Acts||Measures to be Adopted|
|Accidental poisonings||Label and store containers appropriately.|
|Acute poisonings||Restrict accessibility or adopt methods to prevent its access, like control programs by the government.|
|Over usage||Designated locations in rural areas and cities for safely storing of pesticides|
