“…Atrazine can migrate to the aquatic environment through rainfall-runoff, atmospheric deposition, and subsurface and groundwater leaching [ 21 ]. Due to the scale of global agricultural application, atrazine is commonly found in surface water, groundwater, sediment, soil, and the oceans [ 22 , 23 , 24 ]. Atrazine, recognized by U.S. Environmental Protection Agency (EPA) as an endocrine-disrupting compound and a possible human carcinogen, is the second most-used herbicide in the United States [ 25 ].…”

Atrazine, one of the most commonly used herbicides in the world, is of concern because of its frequent occurrence in various water bodies and the potential threat it constitutes to ecosystems. The transport of contaminants in seasonally ice-covered lakes is an important factor affecting the under-ice water environment, and changes in phase during ice growth and melting cause redistribution of atrazine between ice and water phases. To explore the migration pattern of atrazine during freezing and thawing, laboratory simulation experiments involving freezing and thawing were carried out. The effects of ice thickness, freezing temperature, and initial concentration on the migration ability of atrazine during freezing were investigated. The results showed that the relationship between the concentration of atrazine in ice and water during freezing was ice layer < water before freezing < water layer under the ice. Atrazine tended to migrate to under-ice water during the freezing process, and the intensity of migration was positively correlated with the ice thickness, freezing temperature, and initial concentration. During the thawing phase, atrazine trapped in the ice was released into the water in large quantities in the early stages. The first 20% of meltwater concentration was significantly higher than the average concentration in ice, with the highest case being 2.75 times the average concentration in ice. The results reported in this study are a useful reference for planning possible pollution control measures on such lakes during their freeze-thaw process.
