- The inadequacies of pre-market chemical risk assessment's toxicity studies—the implications
Anthony C. Tweedale
Version of Record online: 26 OCT 2016 | DOI: 10.1002/jat.3396
Industry provides the data in pre-market chemical risk assessments. Comparison of two randomly chosen chemical's toxicity literature – academia's versus industry's – and a brief history of pre-market RA and of the OECD test guidelines, reveal inadequacies in industry's key chronic toxicity studies, which nevertheless are used to authorize chemicals for market.
- Toxicokinetics and toxicodynamics of chlorpyrifos is altered in embryos of Japanese medaka exposed to oil sands process-affected water: evidence for inhibition of P-glycoprotein

Effects of acidic, basic and neutral fractions of water soluble organic compounds from oil sands process water (OSPW) on the function of P-glycoprotein (P-gp) were investigated using Caco-2 cells and larvae of Japanese medaka. Basic and neutral fractions inhibited P-gp. Acute toxicity, accumulation, bioconcentration, and half-life of chlorpyrifos, a model compound used as a substrate of P-gp, were greater in larvae co-exposed with a mixture basic and neutral compounds. Results support chemosensitization as a potential mechanism of toxicity of OSPW.

Bjerkandera adusta (B.ad) and benzo[a]pyrene (BaP) each activated antigen-presenting cells (APCs) in the presence and the absence of heated Asian sand dust particles (H-ASDs). H-ASDs alone slightly activated APCs. The activation induced by B.ad was more apparent than that by BaP in the presence and absence of H-ASDs. B.ad rather than BaP contributes to the exacerbation of asthma regardless of the presence or absence of sand particles, particularly by activation of the immune system via APCs.
- Immunomodulatory effects of metal salts at sub-toxic concentrations

Version of Record online: 7 OCT 2016 | DOI: 10.1002/jat.3390
Because different metals are used in complementary medicine for the treatment of diseases related to a dysfunction of the immune system, this study aimed at determining the immunomodulatory potential of Pb(NO3)2, AuCl3, Cu(NO3)2, HgCl2, AgNO3, SnCl2, AsCl3 and SbCl3 and possible toxic side effects of metal preparations. The results show that only copper preparations are promising to have immunomodulatory effects. Comparative analyses with upper limits of metals in the drinking water further showed that toxic side effects of low-concentrated metal preparations are improbable.
- Comparison of the local pulmonary distribution of nanoparticles administered intratracheally to rats via gavage needle or microsprayer delivery devices

Nanoparticle suspensions can be delivered in liquid state, via gavage needle or as liquid aerosol, using a microsprayer as the intratracheal delivery device. We quantitatively evaluated TiO2 pulmonary microdistribution (per mesh: 100 μm × 100 μm) in lung sections from rats administered an intratracheal dose of TiO2 nanoparticles (6 mg kg−1) via gavage needle or microsprayer, using microbeam X-ray fluorescence microscopy. The evidence suggests that the state of administered nanoparticle suspension does not markedly alter TiO2 pulmonary microdistribution.
