The invention discloses a method and a device for collecting urine for analyzing concentration of phthalic acid ester. The device comprises three parts, namely, an urine receiving cup, urine storing bottles and an urine metering device, wherein the urine receiving cup comprises an urine receiving cup body and an urine receiving cup cap which are pinched through threads; each urine storing bottle comprises an urine storing bottle cup body and an urine storing bottle cup cap which are pinched through screws; the urine receiving cup body and each urine storing bottle cup body are made of glass; the urine receiving cup cap and each urine storing bottle cup cap are made of metal; the urine metering device comprises a glass drawer and a sucking ball. With the adoption of the method and the device, the background pollution in urine collection is extremely reduced; in addition, the collected urine is stored in three urine storing bottles, so that the urine is prevented from being in frequent contact with oxygen during later analyzing, and moreover, the urine is also prevented from being repeatedly frozen and thawed in later analysis.
Description
technical field [0001] The invention relates to a method and equipment for collecting and storing urine, and the collected urine is used for analyzing the exposure degree of semi-volatile organic compound phthalate in human body. Background technique [0002] Phthalates (PAEs) are ubiquitous in the indoor environment, used in plastic products, skin care products, cleaners, air fresheners, and more. Phthalic acid volatilizes from the bulk material at high temperature and appears in the indoor environment in a gaseous state; when the temperature drops, the gaseous phthalates condense into a solid state or adsorb on the surface of other particulate matter and suspend in the air and be inhaled by people or eventually settle on the surface of indoor furniture. PAEs can enter the human body through skin and inhalation, and accumulate in the human body, causing health effects. Collecting urine and analyzing the concentration of PAEs in the human body is of great significance for ...
