What harm does solder do to the human body

There are many occupations around us that many of us are unwilling to do, such as welders. Many people think that welding is not a decent job and look down on it. Few people know that the solder wire used by welders will release a large amount of harmful gases after burning, which will be extremely corrosive to human health. If you don’t understand this or have prejudices against welders, then you might as well take a look at the harm to your body after they use the solder wire.

What harm does soldering do to the human body

1. The main manifestations of the nervous system are neurasthenia, multiple neuropathies and encephalopathy.

2. Digestive system: Mild cases may present with general digestive tract symptoms, while severe cases may present with abdominal colic.

3. In the blood system, lead interferes with the synthesis of hemoglobin, causing changes in its metabolites, such as decreased blood δ-ALAD activity, increased urine δ-ALA, increased urine CP, increased blood FEP and ZPP, etc., which eventually lead to anemia, mostly hypochromic normocytic anemia.

4. Other systemic lead damage to the kidneys is more common in acute, subacute lead poisoning or more severe chronic cases, with the appearance of amino acid proteinuria, red blood cells, white blood cells and casts and renal dysfunction, indicating toxic nephropathy, accompanied by hypertension. Female workers are more sensitive to lead, especially during pregnancy and lactation, which can cause infertility, miscarriage, premature birth, stillbirth and lead poisoning in infants. Male labor can cause a decrease in sperm count, weakened activity and changes in morphology. In addition, it can also cause hypothyroidism.

How harmful is solder to the human body?

1. Acute poisoning

It is reported that the minimum concentration of acute poisoning caused by tin-contaminated canned food and fruit is 50 mg/kg. It has also been reported that people who consumed canned fruit with tin contamination concentrations of 563 mg/kg or 400 mg/kg developed clinical symptoms of acute gastroenteritis such as nausea, vomiting, and diarrhea. This needs to be differentiated from acute bacterial gastroenteritis and symptomatic supportive treatment should be given.

2. Tin Pneumoconiosis

Tin smelting workers working in an environment with a tin fume concentration of 9.362 mg/m3 may develop tin pneumoconiosis. Clinically, there are few symptoms such as cough, sputum, and chest tightness, and most patients have no changes in lung function. The typical chest X-ray shows clusters of round or quasi-round small spot-like shadows widely distributed in both lung fields, resembling small osmanthus flowers with petals, but not fused with each other. Their diameter can reach 3 to 5 mm, with high density and sharp edges.

The hilum of the lung is usually not enlarged. The lung texture is mostly unrecognizable or only vaguely visible. Ten to fifteen years after diagnosis, the spotted shadows in the lung fields on both sides gradually become smaller, the density decreases, the number also decreases, the lung fields gradually become clearer, but the density of the hilum gradually increases. After 25 to 30 years, metallic block shadows of various shapes will form at the hilum of the lung, while the lung fields will be basically clear.

3. Chronic effects

Workers who are exposed to tin tetrachloride for a long time may experience respiratory irritation and digestive tract symptoms, such as nausea, upper abdominal discomfort, constipation, and sometimes shoulder and foot pain. Tin tetrachloride can also cause skin ulcers and eczema.

Solder Hazard Solutions

1. Take a break. Generally, you need to take a 15-minute break after one hour of training to relieve fatigue, because your resistance is the weakest when you are tired.

2. Smoke less and drink more water so that most of the harmful substances absorbed can be eliminated during the day.

3. Drinking mung bean soup or honey water before going to bed can reduce internal heat and help your mood. Mung beans and honey can eliminate a large amount of absorbed lead and radiation!

4. Avoid using the phone as much as possible to avoid radiation. Use your cell phone less often. When you go out, you can't use your cell phone. Here are some suggestions for you.

5. Make the soldering iron brighter and try to use a PPD soldering tip so that when the temperature reaches a certain level, you can use less soldering oil and rosin to reduce the harm to your body.

6. When the soldering oil and soldering tin are smoking, try to tilt your head to the side and hold your breath when brushing the ceiling.

7. Use less thinner and more alcohol. Use alcohol to brush for a longer time and the effect will be similar.

8. Wash your hands

9. Take a shower before going to bed. Go to bed early and get up early to ensure adequate sleep. As long as you sleep well, impurities can basically be discharged from the body.

10. Newbies can wear masks when practicing handicrafts. Practicing handicrafts every day will take a long time, which is the most harmful to the body, so masks are a must!
