Chlorfenapyr is a broad spectrum insecticide. It has a low aqueous solubility, low volatility and, based on its chemical properties, would not normally be expected to leach to groundwater. It is not usually persistent in soil or water systems. It has a moderate mammalian oral toxicity but no other data on human health impact has been identified. There are also gaps in ecotoxicilogical data but it is know to be highly toxic to birds, fish and aquatic invertebrates.
Data alerts
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.

Note
Estimated concentrations of chemicals with Koc values greater than 9995 ml g⁻¹ are beyond the scope of the regression data used in SCI-GROW development. If there are concerns for such chemicals, a higher tier groundwater exposure assessment should be considered, regardless of the concentration returned by SCI-GROW
