Abstract
Atrazine is a commonly used water-soluble agricultural herbicide in the United States. In this study, we measured the atrazine levels in water, beverages, foods, and urine samples obtained from young students at an urban university. The effects of physiological and behavioral factors were examined. Our results show that water samples obtained from Lake Erie and tap water both contained very low level of atrazine. Beverages and foods had various levels of atrazine contamination. Atrazine was also detected in the urine samples and mid-term physical activity appeared to be a factor to reduce the atrazine level in these subjects.
Highlights
Atrazine (2-chloro-4-ethylamino-6-isopropylamino-striazine, molecular formula C8H14ClN5, molecular weight 215.6 Da) is a colorless or white odorless crystalline solid with the melting point 171-175°C
[15] In this study, atrazine levels in water, foods, and urine samples obtained from young students at an urban university were measured
Our results revealed that atrazine concentrations in the water samples collected were very low compared to the atrazine Maximum Contaminant Level drinking water (3 ppb)
Summary
Atrazine (2-chloro-4-ethylamino-6-isopropylamino-striazine, molecular formula C8H14ClN5, molecular weight 215.6 Da) is a colorless or white odorless crystalline solid with the melting point 171-175°C. It is a water-soluble herbicide used on crops all over America, especially in the Midwestern states. [1] Even atrazine levels lower than the MCL were shown to disrupt female menstrual cycle regularity. [15] In this study, atrazine levels in water, foods, and urine samples obtained from young students at an urban university were measured. The results showed the presence of atrazine with various concentrations in water samples collected from different sources, as well as various beverages and food samples. Data analysis suggests that atrazine levels are lower in subjects with longer physical exercise time in medium-term (a week)
