Relevance of aerobiological studies in Nigeria: a two-year aerospora record of Lagos
AbstractPollen and fungal spores (aerospora) are major atmospheric bioaerosols for pollen allergy sufferers. Aerospora types and concentration vary seasonally, depending upon the flowering period and meteorological factors which are variable in different geographical regions. The aim of this study was to analyze a two-year record of aerospora from two locations (Epe and Ojo) in Lagos (Nigeria), from May 2014 to April 2016. Aerospora were monitored with a modified Tauber sampler. The residual solution was harvested monthly throughout the duration of the study and acetolyzed, and microscopic slides were prepared. Aerospora w...

Decomposition Analysis of Black –White Disparities in Birth Outcomes: The Relative Contribution of Air Pollution and Social Factors in California
Conclusions:
Our results suggest that, although the role of individual and neighborhood factors remains prevailing in explaining black–white differences in birth outcomes, the individual contribution of PM2.5 is comparable in magnitude to any single individual- or neighborhood-level factor. https://doi.org/10.1289/EHP490

Effects of Orally Ingested Arsenic on Respiratory Epithelial Permeability to Bacteria and Small Molecules in Mice
Conclusions:
Peroral arsenic has little effect on local airway immune responses to bacteria but compromises respiratory epithelial barrier integrity, increasing systemic translocation of inhaled pathogens and small molecules. https://doi.org/10.1289/EHP1878

Associations between Greenness, Impervious Surface Area, and Nighttime Lights on Biomarkers of Vascular Aging in Chennai, India
Conclusion:
Greenness, ISA, and NTL were associated with increased SBP, DBP, and cPP, and with reduced FMD, suggesting a possible additional EVA pathway for the relationship between urbanization and increased CVD prevalence in urban India. https://doi.org/10.1289/EHP541

Analysis of morphological and molecular composition changes in allergenic Artemisia vulgaris L. pollen under traffic pollution using SEM and FTIR spectroscopy.
In this study, the influence of air pollution caused by traffic on the structure and chemical composition of common mugwort pollen was investigated. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and curve-fitting analysis of amide I profile was applied to assess the morphological and structural changes of mugwort pollen grains collected from sites with different vehicle pollution levels. Microscopic observations support the conclusion, that the higher the car traffic, the smaller the pollen grains. The obtained results clearly show that air pollution had an impact on different maximum ...

Lessons from Toxicology: Developing a 21st-Century Paradigm for Medical Research
Conclusions
Our proposed new research paradigm, adapted from 21st-century toxicology, would involve the following aspects:
Developing a big picture of human diseases, integrating extrinsic and intrinsic causes, and linking environmental sciences with medical research using systems biology.
Introducing a disease AOP concept, analogous to toxicity AOPs, with the intention of providing a unified framework for describing relevant pathophysiology pathways and networks across multiple biological levels.
Creating a strong focus on advanced human-specific research (in vitro, ex vivo, in vivo, and in silico) in place of empirical,...

Can selection explain the protective effects of farming on asthma?
CONCLUSIONS: No healthy worker selection into farming was observed and changes in asthma prevalence due to early retirement were small. Selection effects are therefore unlikely to explain the protective effects of farming on asthma.

Unusually early flowering of alder in Vienna: first report of Alnus × spaethii in Austria, combined LM and SEM study of alder species and impact on pollen allergy sufferers
Abstract
Different species of alder cause hay fever symptoms in pollen allergy sufferers within Europe: Alnus glutinosa (black alder), A. incana (grey alder), A. viridis (green alder) and more recently A. × spaethii (japonica × subcordata; Spaeth’s alder). In Austria, the alder pollen season usually lasts from January to April (until June in the mountains due to later flowering of A. viridis). The pollen season started very early in 2014, namely by the end of December 2013 in Vienna with the first pollination of alder. Such an early flowering around Christmas is known for A. × spaethii and was first rec...

Children’s Health in Latin America: The Influence of Environmental Exposures
Conclusions: To control environmental threats to children’s health in Latin America, WHO, including PAHO, will focus on the most highly prevalent and serious hazards—indoor and outdoor air pollution, water pollution, and toxic chemicals. Strategies for controlling these hazards include developing tracking data on regional trends in children’s environmental health (CEH), building a network of Collaborating Centres, promoting biomedical research in CEH, building regional capacity, supporting development of evidence-based prevention policies, studying the economic costs of chronic diseases in children, and developing pl...
