Embodiment 1

[0025] Such as figure 1 As shown, the method of the present invention for measuring the concentration of pollutants in the human exposure environment includes the following steps:

[0026] Firstly, the material with adsorption effect is used as the raw material to make the bracelet. The material with adsorption effect can be one or more of PE, PUF, activated carbon, silicone gum and other materials. After the bracelet is manufactured, it needs to be cleaned, dried and sealed. deal with.

[0027] After the bracelet is manufactured, the bracelet is soaked in ethyl acetate, hexane, and methanol at 30°C to remove analysis interference, and then dried and sealed. After processing, the bracelet is stored at -20°C.

[0028] Secondly, hand out the bracelet to the wearer for wearing, and then retract the bracelet after wearing it for a certain period of time.

[0029] The wearer can return the bracelet by mail. The Teflon bag will be issued at the same time as the bracelet, along with instruc...

Embodiment 2

[0036] The wristband of the present invention includes a shell, and the shell is filled with a filler having an adsorption effect, and the filler is one or more of materials such as PE, PUF, activated carbon, and silicone gum.

Abstract

The invention discloses a method for measuring pollutant concentration in a human exposed environment, and the method comprises the following steps: firstly, a material having an adsorption effect isused as a raw material to make a bracelet, and the bracelet is cleaned, dried and sealed after being manufactured; the wristband is distributed to a wearer for wearing, and the wristband is recoveredafter being worn for a certain period of time; impurities on the surface of the recovered wristband are removed and sealed and stored; and finally, relevant pollutants on the wristband are detected. The method for measuring the pollutant concentration in the human exposed environment can easily and effectively evaluate the total exposure of a human body to certain pollutants, reduces blood drawingand urinosocpy which are harmful to the human body, and can better monitor the effects of the air pollutants on the health of the human body.

Description

Technical field [0001] The invention relates to the technical field of environmental pollution and health, in particular to a method and related products for measuring the concentration of pollutants in the human exposure environment. Background technique [0002] In people's daily life and work, whether it is the interaction with the work environment or the surrounding living environment, people will be exposed to a complex mixture of natural and artificial compounds. Pollutants, such as polycyclic aromatic hydrocarbons, pesticides, dioxins and PCBs, may enter the human body through the skin, mouth or inhalation. Research on these pollutants has been conducted for decades. However, considering the diversity of compounds and the generally low exposure levels, it is often difficult to link pollutant exposure to health effects, even in an occupational environment where many target pollutants are identified, linking exposure levels to biological endpoints Getting up is never easy. ...
