Common Environmental Toxins, Like Nicotine, Linked To Depressive Symptoms: Study

The study says the symptoms are feeling hopeless or taking little interest in daily activities.

Toxins commonly present in the environment, such as nicotine and metals, have been linked with depressive symptoms like feeling hopeless or taking little interest in daily activities, according to a study conducted on US adults.

Researchers found that inflammation brought about by these environmental toxins could be one of the possible underlying reasons.

The team of researchers, including those from Peking University, China, analysed toxin levels in blood and urine samples of over 3,400 adults. The data was taken from the National Health and Nutrition Examination and Survey (NHANES), which tracks Americans' health and nutrition.
