I believe many people have had the experience of being poked by a pencil during their school days. Pencil is a kind of stationery we often use when we are students. A pencil is made of a lead core wrapped in wood. Therefore, pencils themselves also contain certain toxins. Therefore, a pencil poking into the flesh can cause certain harm to the body. Next, let’s see if the small black spots that the pencil has poked into the flesh can be removed. There are many symptoms of lead poisoning. 1. Mental behavior: Children are often listless, sleepy, and have fluctuating moods. Some children show increased irritability, irritability, and aggressive behaviors. Young children will have difficulty making friends and communicating. 2. Nervous system: common symptoms include inattention, hyperactivity, fatigue, memory loss and poor academic performance. Some children often complain of dizziness, headaches, and nausea; some experience vision and hearing loss, slow response to sight and hearing, or forgetfulness when reading. 3. Severe cases may cause numbness and weakness of hands and feet, wrist and foot drop, peripheral nerve paralysis, paralysis, convulsions, seizures, and even death. Suggestions: Hematopoietic system: pale complexion, white lips, nail beds and palm lines, anemia, 4. Digestive system: loss of appetite, bad breath, increased tooth decay, black lines on the gums, picky eating, liking to smell gasoline, liking to bite foreign objects (fingers, nails, toys), and often complaining of stomach pain. Some people may suffer from constipation or diarrhea, or alternating between constipation and diarrhea. 5. Immune system: weak and sickly, low immunity, frequent colds and fevers, prone to coughing and high fever when sick, over and over again. 6. Tissue metabolism: Since the absorption, metabolism and functional activities of divalent metal ions such as calcium, zinc and iron are blocked, children always show signs of calcium deficiency, zinc deficiency and iron deficiency. It is easy to develop leg cramps, tooth decay, rickets, anemia, pica, diarrhea, acute and chronic infections, anorexia, hair loss, dermatitis, weakened immunity and decreased intelligence, which affect growth and development. 7. Skeleton and musculoskeletal system: Grow slowly, height and weight never increase. Some children often feel pain below the knee, are not as coordinated as other children in movement, and are always clumsy and bump into things. |
