Exposure to Pollution clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Chemometers to Determine the Environmental and Human Exposome by Mixtures of Pollutants

EXPOSO-METER

Start date: September 1, 2023
Phase:
Study type: Observational

Motivation of this study Human life is full of chemicals: They support the provision of cure, clothes, shelter, transportation and even nourishment of the world population. But can they also represent a risk for humans? Many of these chemicals can be taken up into the human body. Often, they are transformed and excreted directly, but some chemicals persist over longer time periods or accumulate in living organisms. Since there are many thousands of chemicals in the environment and products humans use on a daily basis, there may be complex mixtures around, and consequently also in the human body. The investigators start a new project at the Helmholtz Centre for Environmental Research (UFZ) in Leipzig, Germany. It is called EXPOSO-METER and attempts to make these chemicals measurable in an easy and comparable way, to better characterize this potential hazard. With the valuable contribution of the participants and collaborators, the investigators will be able to describe and compare the situation for similar groups of study participants in Central Europe, North America and Asia. The aim is to characterize the chemicals and see which potential effects their presence may have. In the project, the investigators will also compare human samples to material from the environment, e.g., seal and fox samples, to improve the understanding of the occurrence and fate of chemicals in the environment and in the human body.
