[0005]
However, for our country, the emission characteristics of various pollution sources are still unclear, and the main sources of PPCPs in urban surface water are still inconclusive.
The unclear source of pollution makes it impossible to effectively control the source of pollution discharge, resulting in long-term continuous discharge of PPCPs into the urban surface water environment, posing a threat to the urban ecological environment and human health

Embodiment 1
[0059] The Huangpu River is an inland river in Shanghai and a landmark river in Shanghai. The Huangpu River runs through the urban area of Shanghai. Aquaculture and animal husbandry are relatively developed in the upstream section of the river. The downstream section and some tributaries receive domestic sewage and industrial wastewater before and after treatment in the urban area of Shanghai, which may cause PPCPs to be discharged into the Huangpu River Basin. . At the same time, part of the Huangpu River Basin is still an important source of drinking water for Shanghai. Therefore, it is very necessary to control the discharge of PPCPs to the Huangpu River Basin from the source. Therefore, the new method of tracing the source of PPCPs in surface water was used to analyze the source of PPCPs in different sections of the Huangpu River Basin.

The invention discloses an emission source characteristic index-based tracing method for medicines and personal care products in surface water, and belongs to the field of water environment trace organic matter analysis. The emission source characteristic index-based tracing method particularly includes determination of a characteristic emission source, screening of indicative PPCPs, establishmentof a characteristic matrix model and application of an emission source characteristic index-based tracing method for drugs and personal care products in surface water. According to the emission source characteristic index-based tracing method provided by the invention, the indicative PPCPs in different emission sources are identified and screened; derivation by mathematical model, wherein the percentage of the absolute value of each item in the obtained coefficient matrix in the total number is the contribution rate or the influence weight of each pollution source to the mixed sample, and directly indicates the contribution rate of each pollution source in the surface water, so that the quantitative tracing of the PPCPs in the surface water can be quickly and efficiently completed, and ascientific basis is provided for controlling the PPCPs pollution from the source.
Description
technical field [0001] The invention relates to the field of analysis of trace organic matter in the water environment, in particular to a traceability method for medicines and personal care products in surface water based on the emission source characteristic index. Background technique [0002] Pharmaceuticals and Personal Care Products (PPCPs) include various prescription and non-prescription drugs (such as anti-inflammatory painkillers, antibiotics, hormones, blood lipid-lowering drugs, anticancer drugs, etc.) and personal care products (such as cosmetics, shampoo, Spices, hair dyes, soaps and other common chemicals) are widely used in various fields such as pharmaceuticals, medical care, poultry breeding, food processing, and personal care. [0003] In modern life, PPCPs can be discharged into the natural water environment through various human activities, such as direct discharge of domestic sewage, discharge of effluent from urban sewage treatment plants, discharge of...
