EPA

TSCA

  • “New TSCA” Rules Provide Opportunities for Proactive Companies to Help Shape Initial Outcomes
    The U.S. Environmental Protection Agency (EPA) proposed three new rules in January 2017 that address some of the key legislative requirements of “New TSCA.” By understanding how these rules work, and how they work together, companies affected by these new rules can work proactively with EPA to shape initial outcomes related to the chemicals they manufacture.
  • New Nanomaterial Regulations Require Detailed Information from Industry
    Earlier this year, the U.S. Environmental Protection Agency issued a final rule under the Toxic Substances Control Act establishing reporting and recordkeeping requirements for nanomaterials. This new rule affects companies that manufacture, import, or process chemical substances at the nanoscale, requiring them to report information and maintain records about their materials. EPA will enact the final rule on August 14, 2017.

NIOSH

  • Occupational Drug Hazards: When NIOSH Listing Affects Your Product and What Can Be Done About It
    The National Institute for Occupational Safety and Health (NIOSH) maintains a list of drugs considered hazardous in healthcare settings. This list was originally compiled from hazardous drug lists maintained by the Pharmaceutical Research and Manufacturers of America (PhRMA) and major healthcare institutions. Although the NIOSH list of hazardous drugs was never meant to serve as the basis for limiting access to such drugs, this has been an unintended result of its existence.

Toxicology News

  • Service by Exponent Scientist on National Committees Regarding the Health Effects of Air Pollution

    The Report of the Committee on the Assessment of the Department of Veterans Affairs Airborne Hazards and Open Burn Pit Registry was released February 28, 2017. Exponent toxicologist, Dr. Joyce Tsuji, served as a member of this committee and is currently serving on the National Academies Standing Committee on Medical and Epidemiological Aspects of Air Pollution on U.S. Government Employees and their Families.

Climate: Extreme Weather

  • Extreme Weather: The Effectiveness of Dual-Polarization Radars
    Dual-polarization radar technology, now implemented at National Weather Service radars across the United States, provides significant added capability to diagnose hail in thunderstorms. Using radar reflectivity and two derived parameters available from dual-polarization radars, the differential reflectivity (i.e. difference between the horizontal and vertical reflectivity components), the correlation coefficient (correlation between horizontal and vertical reflectivity), and the areas of ground level hail impacts can be detected and hail size estimated. 
  • Extreme Weather: Preparing for Tornadoes, Hailstorms, and the Hurricane Season
    We are currently well into the severe tornado and hail season in the United States. Hurricane season will begin on June 1, and hurricane frequency reaches peak activity around September, when the chances for destructive wind and flooding from these storms are highest. Exponent’s team of atmospheric scientists, engineers, industrial hygienists, and health consultants offers a select group of services to assist our clients in the event that a tornado, hailstorm, or hurricane strikes our borders.

  • Epidemiology of Mesothelioma of the Pericardium and Tunica Vaginalis Testis
    Malignant mesothelioma, a rare cancer of the thin protective layer of tissue covering most internal organs, usually occurs in the pleura, the tissue surrounding the lungs, and in the peritoneum, the internal lining of the abdominal cavity.
  • The Future of Developmental Toxicity Testing
    An important aspect of the safety profile for medicines, chemicals, and physical agents is the protection of developing offspring from the potential adverse effects of in utero exposures. To this end, the standard safety test design for this type of endpoint was developed in the mid-1960’s and has changed little in the ensuing half-century. Dr. John M. DeSesso recently authored an opinion that explores the future of developmental toxicity testing and how this will impact safety testing.
  • International Society for Quality of Life Research’s 24th Annual Conference
    Ms. Jordana Schmier, Senior Managing Scientist in Exponent’s Health Sciences practice, will be presenting the poster, “Stakeholder engagement in identifying the burden of illness of geographic atrophy,” at the International Society for Quality of Life Research’s (ISOQOL) 24th Annual Conference.
  • Exponent Scientists at the Forefront of the Science Related to Developmental Toxicity
    Several Exponent scientists currently play instrumental roles in the Teratology Society, a scientific organization dedicated to the understanding and prevention of birth defects and disorders of developmental and reproductive origin.
