No evidence for collateral effects of electromagnetic fields used to increase dissolved oxygen levels on the behavior and physiology of freshwater fishes.

Hypoxia in surface waters driven by warming climate and other anthropogenic stressors is a major conservation concern, and technological solutions for water quality remediation are sorely needed. One potential solution involves the use of low-intensity electromagnetic fields (EMFs) to increase dissolved oxygen levels, but potential collateral effects of the EMFs on aquatic animals have not been formally evaluated. We examined the effects of EMF exposure on wild-caught, captive sunfish (Lepomis spp.

Northern contaminant mixtures induced morphological and functional changes in human coronary artery endothelial cells under culture conditions typifying high fat/sugar diet and ethanol exposure.

It has been reported that Northern populations are exposed to mixtures of various environmental contaminants unique to the Arctic (Northern contaminant mixtures - NCM) at a large range of concentrations, depending on their geological location, age, lifestyle and dietary habits. To determine if these contaminants may contribute to a cardiovascular health risk, especially when combined with a high fat and sugar diet and ethanol exposure, we treated human coronary artery endothelial cells (HCAEC) with two mixtures of 4 organic (NCM1) or 22 organic and inorganic (NCM2) chemicals detected in Northerners' blood during 2004-2005 in the presence or absence of low-density lipoprotein (1.5mg/ml), very-low-density lipoprotein (1.
