Since the invention of the battery, it has brought more convenience to human social life. Many fields are already dependent on batteries. However, the widespread use of batteries can also cause great harm to human beings and society. Lead-acid batteries are a good example. Let's take a look at what lead-acid batteries are doing to the human environment today.
Effects of lead on other organs and system functions.
Lead can damage proximal renal tubules and glomerular cells, leading to increased glomerular filtration rate and impaired tubular absorption. In severe cases, lead - toxic nephropathy may occur. If the lead can inhibit the synthesis of liver mixed functional oxidase, causes damage to liver biological transformation. Reduced detoxification in the liver can also affect human reproductive function, causing sperm abnormalities. Maternal lead can affect fetal development through the placenta, leading to fetal malformation and seriously harming human reproductive health.
Role of lead in the hematopoietic system.
Lead affects the metabolism of phyllophylline, which is an intermediate in the synthesis of hemoglobin. The body reacts with 6-aminolevulinic acid (6-ALA) to produce chologen and with faecoline to produce protoporphyrin. In the synthesis of iron doxorubicin from ferrous iron, there is a disorder in hemoglobin production, leading to lead-induced anemia, especially in children. Lead also inhibits hemolysis caused by sodium-potassium adenosine triphosphate (ATP) and pentose phosphate bypasses on the erythrocyte membrane.
Effect of lead on the digestive system.
Lead poisoning causes a series of changes in gastrointestinal function. Lead inhibits pancreatic function and increases the secretion of salivary and gastric glands. At the same time, the lead will be combined with hydrogen sulfide in the intestines, so that the dissolved hydrogen lost the role of promoting intestinal peristalsis, resulting in stubborn constipation.
Harm to the environment.
Now many small battery factory parts are purchased from the outside (the parts that have great pollution to the environment are purchased from the manufacturers with pollution treatment ability), the use of a new type of automatic injection molding machine, greatly reducing the environmental pollution. The other is a small battery cell forming, adopt the method of internalization, which does not need special molding groove, but with green electricity plate assembly electrode group, into the battery pack, injecting electrolyte, and the use of direct current electricity battery formation forming, avoids forming green electricity plate precipitation of gas in the tank to bring pollution caused by acid mist, reduce the forming after cleaning and drying process, has obvious advantages.
