(Also known as: calcium dichloride) |
Commonly known as salt, this inorganic substance has a range of agricultural uses but is mainly used as a plant growth regulator for fruit thinning. It is highly soluble in water, has a low volatility and is not expected to persist in the environment. It has a low to moderate toxicity, should not bioaccumulate and whilst may cause eye irritation, it is not associated with serious health impacts unless large quantities are consumed. It generally has a low ecotoxicity. |
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.

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 |
