Lung cancer and exposure to nitrogen dioxide and traffic: a systematic review and meta-analysis.
Thursday, April 16, 2015journal article
We found consistent evidence of a relationship between NO2 and NOx, as proxies for traffic sourced air pollution exposure, with lung cancer. Studies of lung cancer related to residential proximity to roadways also suggest increased risk, which may be due in part to air pollution exposure. The International Agency for Research on Cancer recently classified outdoor air pollution and particulate matter as carcinogenic (Group 1). These meta-analyses support this conclusion, drawing particular attention to traffic sourced air pollution. Environmental Health Perspectives.

Ambient coarse particulate matter and hospital admissions in the Medicare Cohort Air Pollution Study, 1999-2010.
Thursday, April 16, 2015journal article
We found statistically significant evidence that daily variation in PM10-2.5 is associated with emergency hospitalizations for cardiovascular diseases amongst Medicare enrollees aged 65 years and above. This association was robust to adjustment for concentrations of PM2.5. Environmental Health Perspectives.

Prenatal polycyclic aromatic hydrocarbon (PAH) exposure, antioxidant levels and behavioral development of children ages 6-9.
Thursday, April 16, 2015journal article

Kidney function and blood pressure in preschool-aged children exposed to cadmium and arsenic -- potential alleviation by selenium.

Childhood cadmium exposure seems to adversely affect kidney function, but not blood pressure, in this population of young children in rural Bangladesh. Better selenium status appears to be protective. Environmental Research.

Children's exposure to indoor air in urban nurseries-part I: CO2 and comfort assessment.
Thursday, April 16, 2015journal article
Non-compliances with guidelines were found in comfort parameters, which could cause discomfort situations and also microbial proliferation. Exceedances in CO2 concentrations were also found and they were caused by poor ventilation and high classroom occupation. Environmental Research.

Human inorganic mercury exposure, renal effects and possible pathways in Wanshan mercury mining area, China.
Thursday, April 16, 2015journal article
The results indicated that human inorganic mercury (IHg) exposure may cause impairment of renal function. By calculation of Probable Daily Intake from different routes, we found that dietary intake is the main pathway of IHg exposure for the local population, rather than inhalation of Hg vapor. Environmental Research.

The association of socio-demographic status, lifestyle factors and dietary patterns with total urinary phthalates in Australian men.
Thursday, April 16, 2015journal article
Phthalate exposure is ubiquitous and positively associated with lifestyle risk factors including smoking, obesity, insufficient physical activity and the highest quartile of the western dietary pattern in urban dwelling Australian men. There was no significant relationship between total phthalate concentration and socio-demographic status. PLoS One.

Association of bisphenol A exposure with overweight in the elderly: a panel study.
Thursday, April 16, 2015journal article
Our results suggest that urinary BPA levels are significantly associated with overweight in elderly women but not elderly men. Environmental Science and Pollution Research International.

Association of urinary metal profiles with altered glucose levels and diabetes risk: a population-based study in China.
Thursday, April 16, 2015journal article
Our results suggest that multiple metals in urine are associated with fasting plasma glucose, impaired fasting glucose or diabetes risk. PLoS One.

Low-frequency electromagnetic field exposure enhances extracellular trap formation by human neutrophils through the NADPH pathway.
Thursday, April 16, 2015journal article
Our study provides a mechanism by which exposure to low-frequency electromagnetic fields could influence the innate immune system. Journal of Innate Immunity.

The public comment period is open until 12 pm Eastern time on June 8, 2015.

If walls could talk: what lead is doing to our students.
Thursday, April 16, 2015news article
A new study published in the Harvard Educational Review suggests that efforts to reduce kids' lead exposure have led to tangible academic gains in Massachusetts. National Public Radio Education.

Midlife plasma vitamin D concentrations and performance in different cognitive domains assessed 13 years later.
Thursday, April 16, 2015journal article
Higher midlife 25(OH)D concentrations were linked to better outcomes concerning short-term and working memory. However, these results were specific to subjects with low education, suggesting a modifying effect of cognitive reserve. British Journal of Nutrition.

Call for comments: Draft EJ 2020 Action Agenda.
Thursday, April 16, 2015announcement
EPA is seeking input on its draft EJ 2020 Action Agenda framework to help EPA advance environmental justice through its programs, policies and activities, and to support the cross-agency strategy on making a visible difference in environmentally overburdened, underserved, and economically distressed communities. Comments will be accepted until June 15, 2015.

WVU researcher warns about toxic ultrafine dust in WVa.
Thursday, April 16, 2015news article
