Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments. The test methods used in the examples are all conventional methods unless otherwise specified; the materials, reagents and the like used are commercially available reagents and materials unless otherwise specified.
The embodiment of the invention is as follows: an environmental pollutant source analytical method comprises the following steps:
1) collecting environmental samples (surface water, sediment and river edge soil of main rivers (such as the Yangtze river, the Oujiang, the Mulanxi, the Jinjiang, the Fujian river, the Yunyujiang, the Yangxuexi and the Qiantangjiang) in Zhejiang province and Fujian province, farmland soil and aquatic products (shrimps, crabs, fishes and shellfish)), recording hydrological meteorological data of sample points, and taking a picture to record the surrounding environment;
2) acquiring original concentration data of a concerned pollutant through chemical analysis, and making data backup;
3) the data is checked and the original concentration data is converted according to the data processing requirement;
4) and (3) data analysis and processing:
firstly, performing correlation analysis by using SPSS software, setting parameters as shown in fig. 1, that is, exploring the correlation between the concentration of the concerned pollutant and environmental factors (atmospheric humidity, pH, water temperature, longitude and latitude, organic carbon percentage, dissolved Oxygen and percentage, ammonia nitrogen Chemical Oxygen Demand (COD), electrical conductivity, main socioeconomic index, etc.), identifying and screening the pollutant with significant correlation, which has similar environmental distribution behavior. The analysis results are shown in table 1.
Then, the SPSS software was used to extract the principal component factors by the maximum variance method (parameter settings are shown in fig. 2 to 4), obtaining factors with characteristic values >1, which can explain the contribution sources (percentages) of the environmental pollutants, respectively, with the results shown in table 2.
TABLE 2 maximum variance extraction principal component factor
Furthermore, the specific value method (in this example, the concentration ratio method) is used to analyze the pollution source of the characteristic pollutant (main pollutant) in the concerned pollutant, and the analysis result of the perfluoroalkyl acid in the polyfluorinated compound is shown in fig. 5, and as can be seen from fig. 5, the pollution source comes from various places such as oujiang, lingjiang, chamjiang, qiantanjiang, minjiang, and vetch, and the like, because water is not only a pollutant receptor of the environmental pollutant, but also a transport medium for the migration and diffusion of the pollutant. The inventor collects samples of surface water, sediment, soil and the like from main rivers of Zhejiang and Fujian province for analysis, by taking surface water as an example, analyzing a pollution source of a polyfluorinated compound (perfluoroalkyl acid) by adopting a characteristic pollutant concentration ratio method, screening out characteristic pollutants by main component factor analysis, obtaining the percentage of the characteristic pollutants from industrial point source emission (surface water transportation and urban runoff) according to local industrial layout, living sources (domestic sewage, human and animal emission, medicines, health care skin care products), transportation (power sources), agricultural sources, energy mineral exploitation and the like, and deducing the production daily emission of the polyfluorinated compound in a river from a fluorinated industrial park area and related processing and manufacturing industries according to the characteristic concentration ratio and the dispersion degree of the polyfluorinated compound (perfluoroalkyl acid) in a figure 5, wherein the polyfluorinated compound in the river enters a water environment through industrial sewage system emission and atmospheric dry-wet settlement; and the second is the discharge of human and livestock, and is mainly from the breeding farm, the personal skin care health care products and the like. The correlation analysis results in table 1 and fig. 5 show that: polyfluoro compounds are likely to be derived from the human or animal excretory pathway; perfluorosulfonic acids (PFBS, PFHxS, and PFOS) are significantly related to other perfluorochemicals, with similar environmental sources.
Finally, the sources of other environmental pollutants (such as perfluorohexanoic acid, perfluorohexane sulfonic acid, perfluorovaleric acid, perfluorononanoic acid, etc., polycyclic aromatic hydrocarbons, antibiotics (macrolides, sulfonamides, tetracyclines, etc.), heavy metals (zinc, copper, chromium, cadmium, mercury, etc.) can be deduced according to the environmental pollutants with significant correlation in the correlation analysis result.
From the results, the scheme of the invention not only can simultaneously analyze a plurality of types of pollution sources, but also can analyze pollutants in a wide-area source. The method provided by the invention mutually complements and explores possible sources and environmental distribution behaviors of the environmental pollutants from various angles, namely, the environmental pollutants are traced by methods such as correlation analysis, maximum variance extraction principal component factor analysis and a ratio method. Organic pollutants such as polyfluorinated compounds, polycyclic aromatic hydrocarbons, antibiotics and the like and heavy metals have the characteristics of durability, biotoxicity, long-distance migration and the like in the environment, and are detected in environmental media such as surface water, underground water, drinking water, municipal sewage treatment plants, water works, surface soil, sediments, benthos, plant tissues and the like and human tissues, so that certain ecological risks and health risks are potential. The scheme of the invention can carry out reliable source analysis on the pollutants, help people to comprehensively recognize the emission and trend of the pollutants, provide valuable reference basis for the reduction and control of the pollutants, and have good market popularization and application prospect.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
