Which Disease is Caused by DDT?

Published in DDT-related Illnesses 2 mins read

DDT, or dichlorodiphenyltrichloroethane, is a pesticide linked to several health problems, though its direct causation of specific diseases is complex and often debated. While DDT itself doesn't cause one singular disease, it's associated with various health issues and has been implicated in contributing to or exacerbating the severity of certain illnesses.

DDT's Role in Disease

  • Cancer: The EPA classifies DDT as a B2 carcinogen, meaning it causes cancer in animals, but human evidence is insufficient. [8]
  • Cardiovascular Disease: Prenatal DDT exposure is associated with an increased risk of hypertension and cardiovascular disease later in life. [16]
  • Liver Disease: In combination with acetyllycopsamine, DDT exposure has been linked to a specific liver disease in the Hirmi Valley. [19]
  • Bird Mortality: Studies have documented significant bird deaths following DDT spraying, implying a direct causal relationship. [2]
  • Epigenetic Effects: DDT exposure can cause epigenetic changes that may increase disease susceptibility across generations. [3, 4]
  • Polio-like Paralysis (Controversial): Some sources suggest that DDT spraying may have been falsely attributed as the cause of polio paralysis outbreaks in the mid-20th century. [7]

It is crucial to understand that the relationship between DDT and disease is often not direct causation but rather a correlation or a contributing factor. The effect of DDT exposure varies based on factors like dosage, duration, and individual susceptibility. Furthermore, the widespread agricultural use of DDT significantly surpasses the quantities used for disease prevention, contributing to widespread resistance and environmental issues. [5] The use of DDT in malaria control, although limited, continues due to its effectiveness against malaria-carrying mosquitoes. [1]

In summary, DDT's association with disease is multifaceted and needs to be considered within its historical context of use. It's not accurate to say DDT causes one specific disease, but instead that it's a known factor potentially contributing to, or worsening, several health conditions.
