Degradation of picoxystrobin and 4-n-nonylphenol in soil.

<p>Degradation curve for picoxystrobin (a) and 4-n-nonylphenol (b) in soil, showing similar pattern and similar percentage degradation during the incubation period for all treatments with picoxystrobin and 4-n-nonylpyhenol, respectively, regardless of initial concentration or mixture situation. Mean values ± SD. Legends: Treatment PI low (a) and NP low (b) (•; PI = 2 mg and NP = 0.5 mg kg<sup>−1</sup> dry soil), PI high (a) and NP high (b) (○; PI and NP = 10 mg kg<sup>−1</sup> dry soil), Mix low (▾; PI = 2 mg and NP = 0.5 mg kg<sup>−1</sup> dry soil), Mix NP high (▵;PI = 2 mg and NP = 10 mg kg<sup>−1</sup> dry soil), Mix PI high (▪;PI = 10 mg and NP = 0.5 mg kg<sup>−1</sup> dry soil), and Mix high (□; PI and NP = 10 mg kg<sup>−1</sup> dry soil).</p>
