Chlozolinate is an obsolete fungicide. It has a low aqueous solubility and is not considered volatile. It is not normally persistent in soil systems and, based on its physico-chemical properties, it is not expected to leach to groundwater. It tends to show a low to moderate toxicity to biodiversity. It has a low mammalian toxicity. No other data is available on its human health effects.
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.
