trace element

While toxic in high concentrations, copper is essential to life as a trace element.

“An analysis of the jar’s trace elements should solve the question of what was inside when the vessel went under,” Dr. Sharvit said.

Fertilizers in the study showed different concentrations of trace elements, with higher levels observed in fertilizers from the U.S. and the Middle East compared to those from China and India.

Like the tree pollen that might be plaguing you this spring, small concentrations of trace elements in the air can have significant negative impacts on human health.

Storage of nutrients like nitrogen and phosphorus, but also of many trace elements, are considered a crucial ecosystem service of places like the Wester- and the Oosterschelde.
