Mild cognitive impairment (MCI) describes the intermediate state between normal cognitive aging and dementia. Adverse effects of air pollution (AP) on cognitive functions have been proposed, but investigations of the simultaneous exposure to noise are scarce. The objective of the study was to analyze the cross-sectional associations of long-term exposure to AP and traffic noise with overall MCI, amnestic (aMCI) and non-amnestic (naMCI) MCI.

Exposure to traffic noise has been associated with adverse effects on neuropsychological outcomes in children, but findings with regard to behavioral problems are inconsistent. The researchers investigated whether residential road traffic noise exposure is associated with behavioral problems in 7-year-old children.

Three decades of rapid economic development is causing severe and widespread PM2.5 (particulate matter ≤ 2.5 μm) pollution in China. However, research on the health impacts of PM2.5 exposure has been hindered by limited historical PM2.5 concentration data. The researchers estimated ambient PM2.5 concentrations from 2004 to 2013 in China at 0.1° resolution using the most recent satellite data and evaluated model performance with available ground observations.

Wastewater is increasingly being used in the agricultural sector to cope with the depletion of freshwater resources as well as water stress linked to changing climate conditions. As wastewater irrigation expands, research focusing on the human health risks is critical because exposure to a range of contaminants must be weighed with the benefits to food security, nutrition and livelihoods.

From 2010-2013, integrated health and environmental responses addressed an unprecedented epidemic lead poisoning in Zamfara State, northern Nigeria. Artisanal gold mining caused widespread contamination resulting in the deaths of more than 400 children. Socio-economic, logistic, and security challenges required remediation and medical protocols within the context of local resources, labor practices, and cultural traditions.

Thallium (Tl) is a highly toxic heavy metal widely present in the environment. Case reports have suggested that maternal exposure to high levels of Tl during pregnancy is associated with low birth weight (LBW), but epidemiological data are limited. This study was designed to evaluate whether prenatal Tl exposure is associated with an increased risk of LBW.

Long-term exposure to fine particles (particulate matter ≤ 2.5 μm; PM2.5) has been consistently linked to heart and lung disease. Recently, there has been increased interest in examining the effects of air pollution on the nervous system, with evidence showing potentially harmful effects on neurodegeneration.

The researchers objective was to assess the potential impact of long-term PM2.5 exposure on event time, defined as time to first admission for dementia, Alzheimer’s (AD), or Parkinson’s (PD) diseases in an elderly population across the northeastern United States.

More than half the European passenger fleet is diesel-powered. Although the European Union has been progressively tightening vehicle emissions for decades, new diesel cars still produce on-road nitrogen oxide emissions that far exceed the current standard. Efforts to reduce diesel emissions would likely make the cars more costly, but experts say it can—and should—be done.

A dramatic disparity between the results of blinded versus open trial designs has raised questions about the effectiveness of water quality interventions and other environmental interventions to prevent diarrhea, a leading killer of young children in low-income countries.

Organophosphorous (OP) pesticides are associated with reduced fetal growth in animals, but human studies are inconsistent. Researchers pooled data from four cohorts to examine associations of prenatal OP exposure with birth weight (n=1,169), length (n=1,152), and head circumference (n=1,143).
