How extreme heat increases pesticide toxicity for farmworkers
Extreme heat increases pesticide toxicity for farmworkers by accelerating dermal absorption, chemical volatility, and the failure of protective gear.

Groundwork ResearcherExtreme heat increases pesticide risks by accelerating chemical volatility, enhancing skin absorption through sweat, and making essential protective gear physically dangerous. Farmworkers face a compounding crisis where heat-induced physiological stress reduces the body's ability to process toxins. Prioritize early-morning work schedules and dynamic safety protocols to mitigate these intersecting hazards.

Yes, sweating increases the permeability of your skin pores, which facilitates the faster and deeper absorption of pesticides into your bloodstream. When combined with the increased blood flow to the skin caused by heat, your body's natural defense against external chemicals is significantly compromised.
Heat increases the volatility of pesticides, causing them to evaporate into the air more quickly and travel further as toxic vapors. In some cases, high temperatures can also trigger chemical reactions that convert standard pesticides into more toxic compounds, increasing the risk of inhalation exposure.
Protective gear traps heat and prevents sweat evaporation, which significantly increases the risk of heat-related illnesses like heat exhaustion. This creates a dangerous trade-off where workers must choose between the risk of chemical exposure and the risk of physical collapse from overheating.
The most effective strategy is to shift high-exposure tasks to cooler hours of the day, such as early morning or late evening. This reduces the physiological stress on the body and minimizes the rate at which pesticides evaporate or transform into more dangerous airborne compounds.
