Toxicity Profile |
---|
Route of Exposure | Inhalation (8) ; oral (8) ; dermal (8) ; eye contact (8). |
---|
Mechanism of Toxicity | Binds to nAChRs in nervous systems. It also causes endocrine disruption in humans by binding to and inhibiting the estrogen receptor. (3, 2) |
---|
Metabolism | Three major and one minor metabolic pathways are proposed. One pathway involves hydrolysis of the ether, followed by oxidation of the resulting alcohol, ester hydrolysis, or N-dealkylation of the ester chain. A second pathway involves oxidation of an aromatic methyl to the benzylic acid or ester hydrolysis. The third major pathway is ester hydrolysis, sometimes followed by benzylic acid formation. The minor pathway involves hydroxylation at the meta position of the phenyl ring. The majority of urinary metabolites are conjugated (glucuronide or sulfate) whereas fecal metabolites are mostly unconjugated. The major metabolite in urine & feces is N-(2,6-dimethylphenyl)-N-(hydroxyacetyl) alanine. Metalaxyl is excreted in urine and the feces. (9) |

Carcinogenicity (IARC Classification) | No indication of carcinogenicity to humans (not listed by IARC). |
---|
Uses/Sources | Widely used selective herbicide worldwide in corn, soybean and other crop cultures. Elevated concentrations of this herbicide and its degradation products have been detected in surface and groundwater. (1) |
---|
Minimum Risk Level | Not Available |
---|
Health Effects | ARDS/acute lung injury, burns of the esophagus or gastrointestinal tract can result from metalaxyl poisoning. (4) |
---|
Symptoms | Metalaxyl is mildly irritating to the skin and eyes. Exposure to metalaxyl often results in such nonspecific symptoms as headache, dizziness, weakness, and nausea. Metaxyl poisoning can produce an allergic hypersensitivity dermatitis or asthma with bronchospasm and wheezing with chronic exposure. (4) |
---|
Treatment | Consider gastric lavage, as well was dilution with milk or water after ingestion. Administer charcoal as a slurry following ingestion; however, activated charcoal should not be given to patients ingesting strong acidic or basic caustic chemicals. In case of inhalation, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Following dermal exposure, remove contaminated clothing and wash exposed area thoroughly with soap and water. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines. Administer symptomatic treatment as necessary. (4) |
