Abstract

The invention relates to a co-detecting method for environmental estrogens in a surface water body, and aims at solving the problems that the treatment process time is long, a large quantity of samples and reagents are consumed in an off-line solid phase extraction method, the process is complicated, the interference factors are more, and loss is large. The co-detecting method is implemented through the following steps that 1, sample collecting and pretreating are performed; 2, filtering and enriching are performed, wherein a to-be-detected surface water body sample which is preserved after being pretreated are enriched and purified through an on-line solid phase extraction device column; 3, detecting and analyzing are performed, wherein a result obtained in the step 2 is detected by adopting an ultra-high performance liquid chromatography tandem mass spectrometer to obtain the detection limit and a quantitative and qualitative result of the seven environmental estrogens in the to-be-detected surface water body sample; 4, a standard curve is obtained; 5, the result obtained in the step 3 is compared with the standard curve to obtain the content and recovery rate of the environmental estrogens. The co-detecting method is applied to the field of surface water detection.

Description

technical field

[0001] The invention relates to a co-detection method for environmental estrogen in surface water bodies. Background technique

[0002] Environmental estrogens (EEs) refer to a class of compounds that interfere with the metabolism of normal endocrine substances and disrupt the stability of the body after entering the body, including polychlorinated biphenyls, dioxins, bisphenols and alkylphenols, and phthalic acid Compounds such as esters and steroids. The existence of these substances in extremely small amounts in the environment may cause potential harm to the ecosystem and human health. Such substances can produce endocrine disrupting effects at extremely low concentrations (ng / L level or below), thereby having potential adverse effects on the health and reproduction of humans, domestic animals, and wild animals. The natural steroid estrogens estrone (E1), 17p-estradiol (E2), estriol (E3) secreted by human and animal ovaries, and the synthetic estrogen 1...
