BiomonitoringAssessing human exposure to toxic metals and their potential health effects has recently come to the forefront of public concern with frequent stories in the media of elevated metals in many products including infant formula, fruit juice, consumable products containing rice, fish, vaccines, and toys, and in some occupational and residential environments. An ever-increasing demand for definitive answers has prompted body burden studies across the country.

Metal speciation in biomonitoring has been gaining significance because a metal’s valence state and molecular form frequently dictates its availability for uptake into the human body and the subsequent potential for deleterious effects.

For more than a decade, Brooks Applied Labs has been providing services for analytical method development and specialized analyses for trace metals and metal species in a variety of human tissues and fluids including:

  • blood
  • urine
  • hair
  • teeth
  • synovial fluid
  • gastrointestinal fluid
  • fingernails and toenails

Over the years, Brooks Applied Labs has developed a number of analytical methods to overcome the common issues and interferences normally associated with analyzing these complex matrices. The laboratory staff at Brooks Applied Labs is also fully trained in the safe handling of potentially infectious materials and is a BSL2 laboratory.

Biomonitoring Public Projects

Brooks Applied Labs’ specialized metals analytical expertise in this area has been valuable to lawyers for litigation cases, university researchers, and non-profit organizations for public awareness campaigns. Some examples of public, non-confidential projects that Brooks Applied Labs has been involved in include:

Pollution in People Study
Brooks Applied Labs analyzed hair samples for mercury for the Washington Toxics Coalition for their “Pollution in People Study“, a look at contaminant levels in people from Washington State.

Body of Evidence Study
Brooks Applied Labs analyzed methyl mercury in hair, lead in blood, and arsenic species in urine samples from Maine residents for the Alliance for a Clean and Healthy Maine and their study “Body of Evidence: A Study of Pollution in Maine People“.
