The lead content in blood exceeds 100 μ g/L, which exceeds the standard.
The diagnosis of lead poisoning generally requires three main conditions: individual lead exposure history, lead content and clinical symptoms. In view of the distribution of lead in the body and the characteristics of lead poisoning, experts believe that measuring lead content is an important means to diagnose and prevent chronic lead poisoning. Because lead is harmful to human body, the lead content in the body should be zero. But under the current circumstances, this is just an unattainable ideal. In order to guide people to take practical measures to get rid of lead pollution, treat children with lead poisoning, reduce the accumulation of lead in the body and reduce the harm, the best way at present is to understand the history of lead exposure, detect lead content and carry out targeted intervention.
After lead enters the human body through the digestive tract or respiratory tract, it is distributed in bones and other tissues with blood, and some of it is excreted in urine through the liver and kidneys, and some of it is excreted in hair and nails. Therefore, the lead content in urine, feces, teeth, bones, hair and blood may reflect the lead load level in the body to varying degrees.
(1) urine lead determination method
Kidney is the main channel for human body to excrete lead. The rise and fall of lead load in the body can be reflected by urine lead. When the renal function is normal and the lead load in the body is high, the lead excretion with urine is relatively large, otherwise the excretion is relatively small. Moreover, urinary lead is also related to lead in air and blood and symptoms. Therefore, urine lead content can reflect recent lead exposure and lead content in children to some extent, and can be used to observe lead flooding effect. However, the concentration and elimination of lead in urine have changed too much. Although the human body exposed to lead for a long time has a high total lead, the excluded lead is not necessarily high, and the urine lead output of people with renal insufficiency is also low, especially under chronic low-level lead exposure, the spontaneous lead output in urine is low, which is difficult to detect. Therefore, foreign countries pay little attention to its diagnostic value and think that it is unreliable to reflect the lead content in the body. However, it is still a useful biological monitoring index. In addition, urine lead samples are easy to collect, and sampling is also non-invasive to the body.
The mercury content in human body shall not exceed 0.0 1mg/L and 1ng= 1000000mg. After unit conversion, the mercury content in your blood is 0.0007 mg/L, and the mercury content in your urine is 0.00 14 mg/L. That should not pose a threat to your health.
Usually eat more foods rich in protein, such as milk, soybean milk, egg white, etc. And protein can reduce the damage of heavy metals.
I hope it helps you.
