Where It Comes From
Folpet was developed in the 1950s as a contact fungicide for control of fungal diseases on fruits and vegetables [1]. The compound was rapidly adopted for use on apples, pears, grapes, and other fruits due to its broad-spectrum effectiveness. Folpet became widely used globally in fruit crop protection. Environmental and health concerns regarding carcinogenicity emerged in the 1970s-1980s [2]. Regulatory restrictions in some jurisdictions limited use or required additional safety measures. Today, folpet remains available for agricultural use in many regions though use has declined [3].
How You Are Exposed
Agricultural workers applying folpet fungicides face occupational exposure through inhalation and dermal contact. Fruit crop workers encounter exposure during spray application. Crop workers after application may contact residues. Environmental exposure through contaminated water and soil occurs in agricultural areas.
Why It Matters
Folpet is classified as a probable human carcinogen based on animal study evidence. The compound causes respiratory tract and dermal irritation. Animal studies show carcinogenicity and potential reproductive effects. Occupational exposure from repeated application raises cancer risk. Environmental persistence in soil raises chronic exposure concerns.
Who Is at Risk
Agricultural workers applying folpet fungicides face occupational cancer risk. Fruit crop farming communities encounter chronic occupational exposure. Vulnerable populations include pregnant women and children. Workers with years of occupational exposure face elevated cancer risk.

Recovery & Clinical Information
Body Half-Life
Folpet is poorly absorbed systemically due to its reactivity. Hepatic metabolism of absorbed compound produces metabolites. The elimination half-life is estimated at hours in mammals. Bioaccumulation potential is low.
Testing & Biomarkers
Occupational air and dermal monitoring detects exposure. Medical evaluation focuses on cancer screening and occupational disease assessment. Residue analysis of food and water identifies environmental contamination. Baseline and periodic health assessment is recommended for exposed workers.
Interventions
Acute exposure management includes decontamination and supportive care. Contact dermatitis is managed with emollients and topical corticosteroids. Cancer surveillance includes regular health monitoring and screening. Occupational reassignment may reduce future exposure risk.
Recovery Timeline
Acute irritation symptoms develop within 2-6 hours of significant exposure. Systemic effects develop over hours to days. Occupational cancer risk increases over years to decades of chronic exposure. Recovery from acute effects occurs within 1-2 days.
