Study on pesticide residues in Panjin Red Beach Wetland
In order to understand the impact of pesticide residues in the water and soil of the wetland ecosystem in Panjin Red Beach on the degradation of Suaeda heteroptera,water samples and soil samples were collected at different monitoring stations A,B,C,D,E,F and G in Red Beach Scenic Spot in 2018,2019 and 2020,and the types and contents of pesticides were investigated and monitored.The effects of main pesticide residues on the growth of Suaeda heteroptera were discussed.The research results showed that a total of 14 pesticides were detected in the water body in 2018,of which the detection rates were higher than those of Molinate,Propachlor,Mevinphos and Terbufos.The amount of total pesticides detected in soil was higher than that in water.A total of 11 kinds of pesticides were detected in soil,and the detection rates of Atrazine,Propazine,Simetryn and Prometryn were higher.In 2019,a total of 8 kinds of pesticides were detected in water bodies.From the time distribution,the highest pesticide detection amount was found in July,and slightly lower in March,April and May.In 2020,a total of 7 pesticides were detected in water,and 2 pesticides were detected in soil,with the highest net content of Simetryn in water and Atrazine in soil.Therefore,it is speculated that the degradation phenomenon of the Suaeda heteroptera at the monitoring station is very likely caused by pesticides.
