In printing, it is necessary to prevent lead poisoning.

Occupational diseases are the result of comprehensive integration of work environment, habits, and methods. In addition to the necessary labor protection, selectively “picking up on food” can effectively reduce the occurrence of occupational diseases.

Personnel engaged in printing, casting, welding, glass, enamel, etc., have more contact with lead and are prone to cause chronic lead poisoning. The patient's early symptoms were fatigue, metallic taste in the mouth, muscle and joint aches, followed by symptoms such as abdominal pain and neurasthenia. As the condition progressed, symptoms such as slowing of motor and sensory nerve conduction, anemia, and weakened kidney function appeared. Should eat more foods with high acid content, such as lean meat, fish and loach. Eat more carbohydrates, inhibit the absorption of lead, eat more foods rich in calcium, iron and other minerals, such as bone soup, shrimp, soy products, seaweed, animal blood and so reduce lead accumulation.
