The Lingering Effects of Agent Orange in Vietnam

April 30, 2025, marks the 50th anniversary of the end of the Vietnam War. This day commemorates the fall of Saigon and the victory of North Vietnamese forces. However, the aftermath of the war continues to haunt millions of Vietnamese citizens. The use of Agent Orange, a toxic herbicide, has left deep scars on the health of the population. Approximately three million people in Vietnam still suffer from serious health issues related to Agent Orange exposure.

What Is Agent Orange?

Agent Orange was a herbicide used by US forces during the Vietnam War. It was designed to defoliate trees and destroy crops. The chemical consisted of a 50-50 mixture of two herbicides, 2,4-D and 2,4,5-T, along with dioxin, a highly toxic contaminant. While Agent Orange degraded quickly in the environment, dioxin could persist for years, contaminating soil and water.

Extent of Exposure

Between 1961 and 1971, the US military sprayed about 74 million litres of chemicals in Vietnam, with over half being Agent Orange. An estimated 4.8 million Vietnamese and nearly 2.8 million US soldiers were exposed. The concentration used was higher than recommended, leading to severe health consequences for those affected.

Health Impacts

The health effects of Agent Orange exposure are deep. Many Vietnamese people suffer from cancer, diabetes, and severe birth defects. Conditions such as spina bifida and cardiovascular defects have become prevalent among children. The Red Cross of Vietnam reported that at least 150,000 children were born with serious birth defects attributed to dioxin exposure.

Generational Effects

The impact of Agent Orange extends beyond those directly exposed. Studies indicate that second and third-generation relatives may also suffer from health issues related to dioxin. The long half-life of dioxin in the human body exacerbates these effects, leading to inherited health problems.

Environmental Damage

Agent Orange caused extensive environmental harm in Vietnam. Sprayed areas became unsuitable for agriculture, with many regions now covered in coarse grasses. The ecological balance has been disrupted, affecting local wildlife and agriculture for decades.

Efforts for Remediation

In 2006, the US and Vietnam began collaborative efforts to clean up contaminated sites. However, the process is slow and costly. Significant areas remain heavily contaminated, particularly around former military bases like Da Nang. Recent political changes have led to a halt in major clean-up projects, raising concerns about the ongoing health risks.

International Responsibility

The issue of Agent Orange remains politically sensitive. The Vietnamese government asserts that the US should take responsibility for the health impacts of the chemical. Advocacy groups continue to call for reparations and support for victims.

Current Situation

Despite the passage of time, the legacy of Agent Orange continues to affect Vietnam. The health and environmental consequences remain a critical issue, necessitating ongoing international attention and support.
