Degradation of Chlorothalonil in Irradiated Water/ Sediment Systems
Journal of Agricultural and Food Chemistry, 2006Water/sediment systems were used to investigate partitioning behavior between waters and sediments, as well as the degradation of the fungicide chlorothalonil (CHT) in each matrix. Experiments were run in the light and dark simultaneously for 30 days in both creek and pond sediment systems.

Canadian Water Resources Journal, 1994
A stream sampling program to monitor chlorothalonil and three metabolite residues was carried out in six agricultural sub-basins on Prince Edward Island. No chlorothalonil residues were observed but one metabolite 3-cyano-2,4,5,5-tetrachlorobenzamide was observed in two samples of the 78 collected.

Environmental Pollution, 2023
The fungicide chlorothalonil (CTL) and its metabolite hydroxy chlorothalonil (OH-CTL) constitute a risk of soil and water contamination, highlighting the need to find suitable soil remediation methods for these compounds. Surfactants can promote the bioavailability of organic compounds for enhanced microbial degradation, but the performance depends on ...

Chemical and photochemical transformation of chlorothalonil
Toxicological & Environmental Chemistry, 1993Photolysis of chlorothalonil (2,4,5,6‐tetrachloro isophthalonitrile) in dichloromethane by ultra violet light (>290 nm) was investigated. It gave 2,5,6‐trichloro‐1,4‐dicyanobenzene and 5,6‐dichloro‐l,4‐dicyano‐benzene as the major photoproducts. Photolysis was followed by a steady decrease in chlorothalonil and monodehalogenated product concentration ...

Photoreduction of Chlorothalonil Fungicide on Plant Leaf Models
Environmental Science & Technology, 2011Photodegradation is seldom considered at the surface of vegetation after crop spraying. Chlorothalonil, a broad-spectrum foliar fungicide with a very widespread use worldwide, was considered. To represent the waxy upper layer of leaves, tests were performed within thin paraffin wax films or in n-heptane.

Photochemical reaction of chlorothalonil in organic solvents
Bulletin of Environmental Contamination and Toxicology, 1979Substantial residues (up to 40 ppm) of methyl parathion were extracted from clothing worn in a treated cotton field on the 1st day following application. Delaying re-entry until the 2nd or 4th day following application reduced residues by about 90 and 99%, respectively, as compared to the 1st day. The amount of residue accumulated on clothing increased

Toxicity of chlorothalonil to marine organisms
Fisheries Science, 2012We evaluated the acute toxicity of the antifouling biocide 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile (chlorothalonil, TPN) to an alga (Skeletonema costatum), crustacea (Tigriopus japonicus, kuruma prawn Marsupenaeus japonicus), and a teleost fish (red sea bream Pagrus major) commonly found in the coastal waters of Japan.

Photoreactivity of the fungicide chlorothalonil in aqueous medium
Environ. Sci.: Processes Impacts, 2014The photoreactivity of chlorothalonil was studied by means of steady-state irradiation and laser-flash photolysis. Experiments were conducted in water containing acetonitrile as a co-solvent. This fungicide undergoes very slow phototransformation in the first stages of the reaction, but the consumption profile is auto-accelerated.

Chlorothalonil exposure of workers on mechanical tomato harvesters
Toxicology Letters, 1991Worker exposure to chlorothalonil (tetrachloroisophthalonitrile, Bravo during mechanical tomato harvester operations of fruit for processing was estimated from passive dermal dosimetry monitoring (gauze pad and undershirt dosimetry), air concentration measurements and hand washes. Gauze pad dosimeters placed outside of workers' clothing gave an average
