Are soldering materials for electric soldering irons harmful to health?
A netizen roast that he had been soldering with an electric soldering iron in a PCB factory for one year, and he felt uncomfortable. His abdomen was a little swollen. Is soldering toxic? Will it cause lead poisoning.
Actually, it depends on whether the lead solder wire used for soldering with an electric soldering iron at work is lead-free or not, and regular blood lead checks are required. If there is no excess, there will be no problem at all. Is soldering toxic?
Normally, if protection and raw material procurement are carried out according to national standards, soldering will not cause significant harm. Nowadays, lead-free products are mostly used.
Lead is a toxic substance, and excessive absorption by the human body can cause lead poisoning. Ingesting low doses may have an impact on a person's intelligence, nervous system, and reproductive system.
The alloy of tin and lead is a commonly used solder, which has good metal conductivity and low melting point, so it has been used in welding processes for a long time. Its toxicity mainly comes from lead. The lead smoke generated by soldering can easily lead to lead poisoning.
Lead metal may produce lead compounds, all of which are classified as hazardous substances. Lead in the human body can affect the central nervous system and kidneys.
The environmental toxicity of lead to some organisms has been widely confirmed. Blood lead concentration above 10 μ g/dl can produce sensitive biochemical effects, and long-term exposure to lead concentrations exceeding 60-70 μ g/dl can cause clinical lead poisoning.
Lead is definitely toxic, let alone whether soldering has a significant impact on the body. Even ordinary metals can be poisoned if there is too much. When soldering, smoke will appear, which contains an element harmful to the body.
When working, it is best to wear a mask, but it may still have some impact to some extent. Of course, if lead-free solder wire can be used, it will be much safer than lead.
