walknote.eu.org - Did you know that lead is one of the metals widely used in the production of everyday items? The intense exposure to lead can lead to poisoning, particularly in children aged 1-5 years, who are more vulnerable to its effects. The World Health Organization (WHO) recommends a safe threshold for lead levels in blood (BLL) at 5 mcg/dL.
Dr. Dewi Yunia Fitriani, an occupational medicine specialist at the Faculty of Medicine, University of Indonesia (FKUI), emphasizes that lead absorption in children is higher than in adults, with children's bodies absorbing lead 3-5 times more easily. This information was shared during a discussion on "Preventing the Health Impacts of Environmental Lead Exposure" held in Jakarta on January 10, 2024.
As a result of increased lead absorption, lead circulates more easily in the bloodstream and contaminates organs. Dr. Dewi warns that lead entering a child's body can contaminate organs and lead to various health problems. Dr. Ari Prayogo, a pediatric specialist, adds that lead exposure can result in issues such as anemia, delayed growth and development, and brain nerve disorders.
Accumulation of lead in organs, particularly in the central nerves of the brain, can disrupt the functions of the prefrontal cortex (frontal part of the brain), hippocampus, and cerebellum, leading to behavioral disturbances, memory problems, and balance issues.
So, what are the signs of lead poisoning in children? Let's explore these symptoms in detail.
Symptoms of Lead Poisoning in Children
Dr. Dewi mentions that theoretically, blood lead levels (BLL) above 20 micrograms per deciliter (mcg/dL) can cause disruptions in the formation of red blood cells, leading to anemia. Lead poisoning may be challenging to detect in the early stages, with symptoms appearing only after a significant accumulation in the blood.
- Developmental Delay: Children with lead poisoning may exhibit delays in physical and mental development.
- Learning Difficulties: Lead exposure can contribute to difficulties in learning and cognitive functions.
- Irritability: Children may display a quick temper and increased irritability.
- Loss of Appetite: Lead poisoning can lead to a decreased desire to eat, resulting in weight loss.
- Fatigue: Children may experience fatigue and a general loss of energy.
- Abdominal Pain: Lead poisoning can cause stomach pain and discomfort.
- Vomiting: Children may experience vomiting as a result of lead exposure.
- Constipation: Lead poisoning can contribute to bowel irregularities, including constipation.
- Hearing Impairment: Lead exposure may affect hearing, leading to difficulties in auditory perception.
- Seizures: In severe cases, lead poisoning can trigger seizures in children.
- Ingesting Non-Food Items: Children with lead poisoning may exhibit pica, consuming non-food items such as paint chips.
It is important to note that not all children displaying these signs necessarily have lead poisoning. Even seemingly healthy individuals can have elevated blood lead levels exceeding 5 mcg/dL. If you notice any of these symptoms in your child, it is crucial to consult a doctor to determine the cause of their health issues.
Dr. Ari emphasizes that lead exposure can occur through two main pathways: inhalation and ingestion. In children, ingestion is more common as they often put their hands in their mouths. Parents should ensure that their children's hands are clean when put in their mouths and keep them away from potential lead sources.
Lead sources in our home environment may include used batteries, paint, and aluminum kitchen utensils. Therefore, it is essential for parents to regularly check for potential lead sources and take preventive measures to protect their children from lead exposure.
Conclusion
In conclusion, understanding the symptoms of lead poisoning in children is crucial for parents to ensure early detection and intervention. Lead exposure can have severe consequences on a child's physical and mental health, impacting their growth and development. By being aware of the signs and taking preventive measures to reduce lead exposure in the home environment, parents can contribute to the well-being of their children. Regular medical check-ups and maintaining a clean and safe living environment are essential steps in protecting children from the harmful effects of lead poisoning. (wp)
