Tracing multi-pathway transport of progestins, glucocorticoids, and antiprogestin in pilot-scale soil-water systems: Surface runoff, interflow, and leachate dynamics during simulated rainfall events

Key Points

• Surface runoff significantly influences the transport of progestins and glucocorticoids in soil-water systems, leading to potential environmental contamination.
• During simulated rainfall events, interflow and leachate demonstrate varied dynamics, affecting the distribution of hormonal contaminants.
• Analysis of pilot-scale soil-water systems provides insights into the multi-pathway transport of these substances and their environmental fate.
• Understanding these hormone transport mechanisms may indicate potential risks to groundwater and ecosystem health from agricultural runoff.
