Hazard alerts

The following Pesticide Hazard Tricolour (PHT) 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. The alerts for Highly Hazardous Pesticides (HHPs) are based on applying the FAO/WHO (Type 1) and the PAN (Type II) criteria to PPDB data. Further details on the HHP indicators are given in the tables below. Neither the PHT nor the HHP hazard alerts take account of usage patterns or exposure, thus they do not represent risk.

PHT: Environmental fate	PHT: Ecotoxicity	PHT: Human health	Highly Hazardous Pesticide
	Ecotoxicity Low alert: Birds acute ecotoxicity: Low; Fish acute ecotoxicity: Low; Daphnia acute ecotoxicity: Low; Bees acute unknown ecotoxicity: Low; Earthworms acute ecotoxicity: Low	Human health Low alert

Mixture composition

Canola oil is a mixture of triglycerides whose fatty-acid profile is defined by plant breeding: it must contain low erucic acid and low glucosinolates in the meal. Its composition can vary according to region and extraction method but typically includes oleic acid (55-65%), linoleic acid (18-25%), alpha-linolenic acid (8-12%), palmitic acid (3-5%) and stearic acid (1-2%). Its bioactivity is solely due to its fatty acid content.

Formulation and application details

Supplied as an oil formulation

Commercial production

Canola oil production involves transforming canola seeds into the oil. The harvested canola seeds are first cleaned, heated and flaked. Heating helps to soften the seeds, making it easier to extract the oil. Flaking involves rolling the seeds to rupture their outer coating. The flaked seeds are cooked in a series of heating drums or cookers. This step helps to further break down the cell walls and makes the oil extraction process more efficient. The cooked flakes are then pressed using mechanical presses to extract most of the oil. This process is known as expeller pressing. To extract the remaining oil, the pressed seed matter is treated with a solvent. The solvent helps to dissolve the oil, which is then separated from the seed solids. The extracted oil undergoes refining to remove any impurities using methods such as natural clay filters, water, organic acids, and steam.
