Working for Industry, Agencies and Legal Counsel

  • We draw on our 29 years of experience at quantifying toxic chemical sources in outdoor and indoor environments

  • We determine the migration and transformation of source chemicals along with levels of actual human exposure and toxicity

  • We determine chemical intakes and doses absorbed by inhalation, oral ingestion, skin contact, and radiation

  • We test for probable causation where injury or disease is already evident, or we quantify increased risk of future adverse health effects

  • We calculate risk-based levels of contaminant cleanup at source areas or waste sites that will protect community health

  • Besides contaminants in air, water and soil, we analyze toxic chemicals in consumer products, including food and drugs.

    Approach to Serving Clients

    Depending on technical complexity, Dr. Roth-Nelson works independently or may team up with other specialists to round out the exact skills needed for strong client representation.

    We may suggest teaming with a public health epidemiologist, a medical toxicologist, a teratologist, a geneticist, an analytical chemist, a chemical or environmental engineer, a health physicist, an industrial hygienist, a hydrogeologist, and others.

    We are available as nontestifying consultants or expert witnesses on behalf of industrial firms, regulatory agencies, and legal counsel representing defendants or plaintiffs.
