Hazard assessments of manufactured nanomaterials.
BACKGROUND It has been difficult to make reliable hazard assessments of manufactured nanomaterials, because the nanomaterials form large agglomerations in both in vitro and in vivo studies. OBJECTIVE In the New Energy and Industrial Technology Development Organization (NEDO) Project of Japan, the physicochemical properties of many manufactured nanomaterials are being measured, and in vitro an...
متن کاملEvidence for effects of manufactured nanomaterials on crops is inconclusive.
Priester et al. (1) recently investigated the growth of soybean in soil amended with ZnO and CeO2 manufactured nanomaterials (MNMs). It is laudable that the study used soil: Too few studies to date do this. However, we question the agronomic and environmental relevance of this study because of a lack of control experiments with a soluble salt (for ZnO) and with larger-scale particles (for ZnO o...
متن کاملHealthcare workers: protecting those who protect our health.
The nation’s healthcare system is in a transition of potentially historic proportions, driven by the need for cost-effectiveness under pressures of cost containment and competition, but also made possible by scientific and technological breakthroughs.1 This transition presents new challenges and opportunities for protecting the health and safety of our nation’s healthcare workers. Toward the go...
متن کاملDispersion Method for Safety Research on Manufactured Nanomaterials
Nanomaterials tend to agglomerate in aqueous media, resulting in inaccurate safety assessment of the biological response to these substances. The present study searched for suitable dispersion methods for the preparation of nanomaterial suspensions. Titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles were dispersed in a biocompatible dispersion medium by direct probe-type sonicator and i...
متن کاملRisks and control of nanomaterials.
In this issue we bring together 12 articles on nanomaterials and approaches to risk control. The issue opens with a review by Eileen Kuempel and colleagues of the research needs for effective management of these materials. This is followed by two items on tools for control: a review of control banding and a report of discussions on reference values. Then an article describes the development of ...
