DDT molecule

DDT molecule. Computer model of a molecule of the pesticide DDT (dichlorodiphenyltrichloroethane, C14. H9. Cl5). Atoms (spheres) are colour-coded: carbon (red), hydrogen (white), chlorine (blue). DDT attacks the central nervous system of insects. A synthetic pesticide, used since 1939, DDT and its products pollute the environment, taking decades to be broken down. It has been found to accumulate in animal fatty tissues, and so reach dangerous levels in the food chain. Although DDT use was banned in many countries in the 1970s, it is cheap to make and is still used in developing countries

EDITORS COMMENTS
This print showcases a computer-generated model of the DDT molecule, a potent pesticide that has had a profound impact on our environment. The intricate structure of this compound is depicted with atoms represented as color-coded spheres: carbon in red, hydrogen in white, and chlorine in blue. DDT's significance lies in its ability to target the central nervous system of insects, making it an effective insecticide since its introduction in 1939. However, this synthetic chemical and its byproducts have caused widespread pollution and long-lasting environmental damage. It takes decades for DDT to break down naturally, leading to its accumulation in animal fatty tissues and subsequent entry into the food chain. Although many countries banned the use of DDT during the 1970s due to these harmful effects, it remains inexpensive to produce and continues to be utilized in developing nations today. This image serves as a reminder of the complex relationship between mankind's quest for agricultural productivity and the unintended consequences that can arise from such practices. Through this visually striking illustration created by Science Photo Library, we are confronted with both the beauty and danger inherent within chemical compounds like DDT. It encourages us to reflect on our responsibility towards sustainable farming practices while raising awareness about pollutants that persist within our ecosystems.
