Key Details:

• Chemical Structure: Parathion is an organophosphate ester, chemically related to other pesticides.
• Uses: It’s mainly used to control pests on various crops, but its use has declined due to safety concerns.
• Toxicity: Extremely toxic to humans and wildlife; exposure can occur through inhalation, ingestion, or skin contact.
• Symptoms of Exposure: These can include headache, dizziness, respiratory distress, nausea, and even seizures.
• Regulation: Many countries have banned or severely restricted its use due to its potential for harm.

Safety Precautions:

• Proper protective equipment is essential when handling parathion.
• Immediate medical attention is required in case of exposure.

Symptoms of Exposure:

Acute Symptoms:

1. Neurological Symptoms:
   • Headache
   • Dizziness
   • Confusion
   • Tremors
   • Seizures
2. Respiratory Symptoms:
   • Shortness of breath
   • Chest tightness
   • Wheezing
3. Gastrointestinal Symptoms:
   • Nausea
   • Vomiting
   • Diarrhea
4. Muscular Symptoms:
   • Weakness
   • Muscle twitching or spasms
5. Other Symptoms:
   • Excessive salivation
   • Sweating
   • Constricted pupils (miosis)

Chronic Symptoms:

Long-term exposure can lead to:

• Neuropathy
• Cognitive impairments
• Increased risk of certain diseases

CAUSE:

1. Inhalation:

• Breathing in aerosols or vapors while applying the pesticide or being in areas where it has been sprayed.

2. Ingestion:

• Consuming contaminated food or water.
• Accidental ingestion during handling or mixing.

3. Dermal Contact:

• Handling parathion without protective gear can lead to skin absorption.
• Contact with contaminated surfaces or equipment.

4. Environmental Contamination:

• Runoff from treated fields can contaminate nearby water sources.
• Drift from aerial spraying can expose people in surrounding areas.

5. Improper Storage:

• Storing parathion in unsealed containers can lead to spills or leaks.

6. Occupational Exposure:

• Farmers, agricultural workers, and pesticide applicators are at higher risk due to direct handling.

7. Accidental Spills or Leaks:

• Mishandling during transport or application can lead to unintended releases.

RICKS:

1. Acute Toxicity:

• Neurological Effects: Inhibition of acetylcholinesterase can lead to serious neurological symptoms, including convulsions, respiratory failure, and potentially death.
• Respiratory Distress: Severe exposure can cause pulmonary edema and difficulty breathing.

2. Chronic Health Effects:

• Long-term exposure can lead to neurological damage, cognitive deficits, and chronic respiratory issues.
• Increased risk of certain cancers has been suggested in some studies.

3. Environmental Impact:

• Parathion can contaminate soil and water, affecting non-target organisms, including beneficial insects, birds, and aquatic life.
• Residues can persist in the environment, leading to long-term ecological damage.

4. Occupational Risks:

• Farmers and agricultural workers face heightened risks due to frequent handling and application, making them susceptible to both acute and chronic health effects.

5. Regulatory Risks:

• Use of parathion is heavily regulated in many countries due to safety concerns, leading to legal implications for improper handling or application.

6. Emergency Situations:

• Accidental spills or leaks can pose immediate health risks to nearby individuals and require emergency response measures.

TREATMENT:

1. Decontamination:

• Remove Contaminated Clothing: Immediately take off any clothing that may be contaminated.
• Wash Skin: Thoroughly wash the affected skin with soap and water to remove any residual pesticide.

2. Supportive Care:

• Monitor Vital Signs: Continuous monitoring of heart rate, breathing, and blood pressure.
• Oxygen Therapy: Administer supplemental oxygen if the patient is having difficulty breathing.

3. Antidotes:

• Atropine: Administered to counteract the effects of excessive acetylcholine due to acetylcholinesterase inhibition. Doses may be repeated based on symptom severity.
• Pralidoxime (2-PAM): This antidote can help reactivate acetylcholinesterase if given soon after exposure. Its effectiveness decreases over time.

4. Seizure Management:

• Benzodiazepines: Medications like lorazepam or diazepam may be used to control seizures.

5. Hospitalization:

• Severe cases may require intensive care for respiratory support, especially if respiratory failure occurs.

6. Follow-Up Care:

• Patients may need long-term follow-up to monitor for any delayed neurological effects or other complications.

cost of treatment for parathion exposure in India:

1. Hospitalization:

• Public Hospitals: Treatment may be more affordable, potentially ranging from ₹1,000 to ₹5,000 per day, depending on the facility.
• Private Hospitals: Costs can be higher, ranging from ₹5,000 to ₹20,000 or more per day, especially for intensive care.

2. Medications:

• Atropine and Pralidoxime: The cost for these medications can vary. Atropine may cost around ₹50-₹300 per dose, while Pralidoxime can cost between ₹1,000 and ₹3,000 per dose.

3. Additional Treatments:

• Costs for supportive care, oxygen therapy, and other interventions can add to the overall expense, potentially ranging from ₹2,000 to ₹10,000 depending on the complexity.
