Environmental fate: 
Animals:After oral administration of radiolabelled iprovalicarb to rats and to lactating goats, the radioactivity was readily excreted via faeces and urine. Iprovalicarb was metabolised extensively;
Fate in soil:
Iprovalicarb has moderate to low mobility in soil. It has a soil half-life of between 1 and 17 days. The major metabolite in soil degradation studies is p-methyl-phenethylamine (PMPA).
In laboratory studies, the DT₅₀ at 20°C in aerobic soil was found to be 2.0 to 29.6 days (median 10.5 days), whilst the DT₉₀ was in the range 6.7 to 98.3 days (median 34.9 days) at the same temperature. Studies in anaerobic soil were not required as the proposed use of iprovalicarb is as a fungicide for fruits and vegetables.
In field studies, the mean DT₅₀ from 6 trials (two in Southern Europe and four in Northern Europe) was found to be 15.5 days; the DT₉₀ ranged from 15.5 to 64.2 days in Southern Europe and averaged 54.7 days in Northern Europe. Iprovalicarb is unlikely to accumulate in soil as it is not persistent.
The metabolite PMPA was found to have a DT₅₀ of 41 to 118 days (median = 52 days) at 20°C in aerobic soils, and a DT₉₀ of greater than 100 days. In field studies, DT₅₀ was found to be 2.2 to 22 days (mean of 12 days).
The mean K_oc for iprovalicarb was 106 mL/g and that of the metabolite PMPA was 290 mL/g indicating that they have medium mobility in soil.
Leaching studies and lysimeter studies were not carried out as groundwater contamination by iprovalicarb was not expected.

Fate in aquatic systems:
Iprovalicarb is stable to hydrolysis at 25°C in the pH range 5 to 9. It is not susceptible to photodegradation.
In two water/sediment studies, the DT₅₀ and DT₉₀ in water were 54.4 and 18.8 days, and 180.8 and 62.5 days, respectively. For the whole system, the DT₅₀ was 55.7 and 25.3 days, and DT₉₀ 185.1 and 83.9 days.
