2,4-DB

Potential EDCPesticidesDevelopmental_ToxicityMale_Repro_Toxicity

2,4-DB is a weed‑killing herbicide used mainly on alfalfa, clover, and peanut fields. It matters because it can move off fields and end up in air, water, and food [1][2].

Where It Comes From

Agricultural spraying; in plants it can convert to the related herbicide 2,4-D; can reach nearby soil, air, and water [1][2].

How You Are Exposed

Living or working near treated fields (spray drift), handling products, eating treated crops, or drinking contaminated well/surface water [1][3].

Why It Matters

Short-term exposure can irritate eyes and skin; swallowing large amounts can cause nausea and vomiting. Repeated high doses in animals affected liver and kidneys. Cancer evidence in humans is inadequate; EPA did not find cancer risks of concern in its reviews [1][2].

Who Is at Risk

Farmworkers and applicators; people living near fields; infants and children; those using private wells near treated areas [1].

How to Lower Your Exposure

Follow the label and wear protective gear; respect buffer zones and reentry times; close windows during spraying; wash/rinse produce; test private well water if near treated fields [1][2][3].
