Plastic bracelet for monitoring exposure degree of perfluorinated compound

Abstract

The invention provides a plastic bracelet for monitoring the exposure degree of perfluorinated compounds. Comprising a connecting ring and a fixing ring, a first plastic rod and a second plastic rod are placed on the inner wall of the connecting ring and the inner wall of the fixing ring correspondingly, clamping grooves are formed in the first plastic rod and the second plastic rod correspondingly, rolling blocks are arranged on the connecting ring and the fixing ring correspondingly, and shaft rods are in threaded connection with the rolling blocks; a clamping groove is formed in the connecting ring, a clamping block matched with the clamping groove is fixed to one end of the shaft rod, a contact ring is fixed to the rolling block, a clamping hole is formed in the rolling block, sliding rods matched with the clamping hole are arranged on the connecting ring and the fixing ring in a sliding mode through fixing blocks, and shaft blocks are fixed to the sliding rods. According to the plastic bracelet for monitoring the exposure degree of the perfluorinated compound, provided by the invention, the raw materials for preparing the bracelet are environment-friendly materials and are relatively cheap, secondary pollution is not caused in the use process, the use cost is reduced, the plastic bracelet is suitable for large-scale popularization, and the use process is simple and convenient.

Description

technical field [0001] The invention relates to the field of wristbands, in particular to a plastic wristband for monitoring the exposure degree of perfluorinated compounds. Background technique [0002] Perfluorinated compounds (PFASs) are widely used in various industrial and commercial products to improve the performance of products, such as foam fire extinguishers, chromium inhibitors, kitchenware, packaging bags and waterproof clothing, etc. With the wide application of PFASs products, various The presence of PFASs has been detected in various environmental, animal, plant and human media, including surface water, groundwater, soil, atmosphere, human blood and urine. Epidemiology and toxicology have successively shown that PFASs can negatively affect human health, such as endocrine disruption, disruption of lipid homeostasis, immunotoxicity, liver toxicity, and developmental toxicity. Preventing the health risks of PFASs is crucial, and blood and urine are often used as...

Problems solved by technology

Although these studies have shown that the silica gel adsorption phase wristband as a passive sampler can effectively determine typical semi-volatile organic compounds, but for the adsorption phase of other materials (such as: high-density polyethylene (HDPE) and thermoplastic polyurethane (TPU)) wristband There are still research gaps in the application of these wristbands in the determination of new organic pollutants (such as: PFASs) in ordinary and occupational populations.
