Endocrine disruptors, or EDs, are chemicals, either natural or man-made, that mess with an organism’s normal hormones. This can really impact their health. Many of these substances cause problems even in tiny amounts. Think about it- the endocrine system is super important for growth. So, organisms in early stages- like fetuses, children, and those going through puberty- are especially sensitive to EDs. Plus, when these chemicals combine, they can act in surprising ways, sometimes making each other stronger, weaker, or creating new effects entirely. Knowing all this, it’s crucial to find out if these compounds are in our drinking water.
That’s why this study focused on checking for substances with suspected or known endocrine activity in drinking water from the Madrid Region, Central Spain. They also wanted to see if these substances caused estrogenic, androgenic, or thyroidal activity. Researchers collected water samples at different times from various supply points, which got their water from reservoirs or rivers.
The sampling point with the most analyzed substances- up to 30 different compounds- was DW1, with 1203 ng/L. This spot gets its water from a drinking water treatment plant that serves people in the south of the Madrid Region, using treated water from the Tajuña River. DW2 came in second, with 1021 ng/L of these substances. DW2 gets its water from a reservoir in the northern part of the region. The highest daily concentrations found were for Tris (2-chloroethyl)phosphate (TCEP), a flame retardant, at 266.55 ng/L at DW1, and nonylphenol diethoxylate at 188.57 ng/L at DW4. Both of these points receive treated river water.
Interestingly, none of the water samples showed androgenic, estrogenic, or thyroidal activity in the lab tests. These tests use cells modified to react to specific receptors, with luciferase as a marker. This tells us that the water quality in the Madrid Region is good and doesn’t pose a health risk to people. Still, because some of these substances are present, local authorities need to keep monitoring for these contaminants. That way, they can step in and fix things if necessary.
