High-purity reference materials for accurate residue analysis in food and environmental samples.

Overview

Chlorothalonil, also known as 2,4,5,6-Tetrachlorobenzene-1,3-dicarbonitrile, is a broad-spectrum, non-systemic fungicide. It is widely used in agriculture and other industries to control mold, mildew, bacteria, and algae.

First registered for use in the US in 1966, it is sold under various trade names such as Bravo, Echo, and Daconil.

Uses

Chlorothalonil is predominantly used on peanuts, potatoes, and tomatoes in the US. It is also applied on golf courses, lawns, and as a preservative in paints, resins, emulsions, and coatings.

It is available in multiple formulations including dust, wettable powder, liquid spray, fog, and dip, and can be applied by hand, ground sprayer, or aircraft.

Regulatory

The European Union banned the use of chlorothalonil in March 2019, effective from May 2020, due to health and environmental concerns. Switzerland followed suit in December 2019.

US regulations limit hexachlorobenzene (HCB) contamination in chlorothalonil to 0.05% due to its toxicity.

Monitoring

Chlorothalonil has been detected in ambient air in Minnesota and Prince Edward Island, as well as in groundwater in Long Island, New York, and Florida. It has also been linked to several fish kills in Prince Edward Island.

The main breakdown product, hydroxy-2,5,6-trichloro-1,3-dicyanobenzene (SDS-3701), is more acutely toxic and persistent in the environment.

Health Impact

Chlorothalonil is a Category I eye irritant and Category II for inhalation toxicity. Long-term exposure has been linked to kidney damage and tumors in animal studies. It is classified as a Group 2B possible human carcinogen.

Environmental Impact

Chlorothalonil is highly toxic to fish and aquatic invertebrates but not to birds. It has been implicated in the decline of honey bee populations by increasing their vulnerability to the gut parasite Nosema ceranae.

At certain concentrations, it has been found to kill amphibians like frogs within 24 hours of exposure.

Safety Measure

Due to its toxicity, chlorothalonil should be handled with care, following all precautionary statements such as P201, P202, P260, P261, P271, P272, P273, P280, P281, P284, P302+P352, P304+P340, P305+P351+P338, P308+P313, P310, P312, P320, P321, P333+P313, P363, P391, P403+P233, P405, and P501.
