Plant growth effects due to drugs in the environment

A research has shown that the growth of edible crops could be effected with the use of chemicals like non-steroidal anti-inflammatory drugs. They effects even if a very low concentrations found in the environment.The research focused its analysis on lettuce and radish plants and tested the effects of several commonly prescribed drugs, including diclofenac and ibuprofen. These drugs are among the most common and widely used group of pharmaceuticals, with more than 30 million prescribed across the world every day. The potential for some chemicals to influence plants is becoming increasingly relevant, particularly as waste management systems are unable to remove many compounds from our sewage. Drugs for human use make their way into soil through a number of routes, including the use of sewage sludge as fertilizer and waste water for irrigation. This study looked for a number of changes in edible plants, assessing factors such as water content, root and shoot length, overall size and how effectively the plants photosynthesized. Each drug was shown to affect the plants in very specific ways, with marked differences between drugs that are closely related. For example, drugs from the fenamic acid class affected the growth of radish roots, whilst ibuprofen had a significant influence on the early root development of lettuce plants..
