Soil

Compound (name and/or code)	Persistence	Ecotoxicology
Alpha‐cypermethrin	Low to moderate persistence Biphasic kinetics DT50 3.8–48.1 days (DT90 45.7–329.4 days; laboratory conditions at 20°C, 40–50% MWHC soil moisture) EU and US field dissipation studies single first‐order and biphasic kinetics DT50 3.4‐46.1 days (DT90 13.4–250.5 day)	Low risk to soil dwelling organisms.
3‐PBA	Very low to low persistence Single first order and biphasic kinetics DT50 0.38–5.0 days (DT90 1.3–16.0 days; laboratory conditions at 20°C, 40–50% MWHC soil moisture)	Low risk to soil dwelling organisms.
(cis‐)DCVA	Low to moderate persistence Single first order DT50 2.7–13.5 days (DT90 10.0–45.0 days; laboratory conditions at 20°C, 40–50% MWHC soil moisture)	Low risk to soil dwelling organisms.
M310I017	Low to moderate persistence Single first order DT50 4.9–42.3 days (DT90 16.2–140.4 days; laboratory conditions at 20°C, 40–50% MWHC soil moisture)	Low risk to soil dwelling organisms.

DT₅₀: period required for 50% dissipation; DT₉₀: period required for 90% dissipation; MWHC: maximum water‐holding capacity.
