Toxins

Commonly found in old paint dust, aging pipes, and contaminated soil, lead is one of the more widely studied environmental elements. It is worth monitoring over time, particularly for families with young children, given research pointing to links with development and behavior.

Found in tobacco smoke and some leafy vegetables grown in contaminated soil, cadmium is an element where long-term patterns tell the most meaningful story. Research has pointed to links with kidney function and bone density, so tracking patterns over time gives you a more informed picture.

Nickel turns up in more places than most people realize: stainless steel cookware, jewelry, and everyday foods including nuts and chocolate. Research has linked higher contact levels to skin sensitivity, and some studies in people with heavy occupational exposure have pointed to effects on the lungs.

Naturally occurring in some well water, rice, and materials used in older building treatments, arsenic is an element where context matters. Research has noted associations with skin, lung, and heart health in studies of long-term exposure, so understanding how your levels sit over time is genuinely useful.

Barium is present in some groundwater, everyday foods including nuts and grains, and certain medical imaging products. Research has pointed to links with heart rhythm and blood pressure at elevated levels, so knowing where you sit relative to others gives you a useful starting point.

One of the most widely encountered metals in daily life, aluminum is present in cookware, antiperspirants, and some antacids. Research has noted associations with bone health and brain function at elevated levels, and knowing where you sit relative to others adds a useful layer to your overall exposure picture.
