A recent study published in Environmental Science & Technology found that farmed salmon have significantly higher levels of flame retardants, including polybrominated diphenyl ethers (PBDEs), than wild salmon. Wild Chinook salmon from British Columbia showed the highest average PBDE levels.
A study by Canadian scientists found high levels of pollutant films on windows in lower Manhattan six weeks after the 9/11 attacks, revealing concentrations up to 10 times greater than normal background levels. The findings suggest that urban areas like New York City have high levels of toxic organic pollutants.
A new study led by Duke University and NIST found a correlation between sea turtle health and high levels of toxic organic chemicals. The research team analyzed blood and fat samples from 48 juvenile turtles in North Carolina waters, discovering changes in immune function, liver damage, and protein regulation.
A study published in Toxicological Sciences found that a toxin combination common in fish impairs motor skills, particularly when combined with PCBs. The research suggests that additive toxic effects of these chemicals on human health should be seriously considered.
Researchers at Indiana University found that farmed Atlantic salmon contain significantly higher levels of toxins, including PCBs and dioxins, than wild Pacific salmon. These toxins are linked to human health concerns and may pose a risk to people who eat salmon regularly.
A research team from Purdue University and the University of British Columbia has identified a bottleneck in the degradation of polychlorinated biphenyls (PCBs), a persistent and hazardous industrial chemical. By breeding bacteria to overcome this hurdle, the team hopes to develop an environmentally friendly solution for cleansing the ...
Research found that men exposed to polychlorinated biphenyls (PCBs) before age 20 had a lower chance of having a baby boy, with a 35% difference. The study's lead author proposes that dioxin-like compounds may negatively impact the viability of Y-chromosome carrying sperm or XY-fertilised eggs.
A University of Illinois study found that sunlight and PCB exposure enhance the development of non-melanoma skin cancer on parts of the body not directly exposed to the sun. Mice exposed to both sunlight and PCBs developed tumors, while those with only PCB exposure did not.
A recent study published in the Journal of Occupational and Environmental Medicine found that men with higher levels of polychlorinated biphenyls (PCBs) were more likely to father boys. Researchers analyzed data from 208 children born to 101 families, where PCB levels were detectable in both fathers and mothers.
Researchers have discovered a microbe that can break down polychlorinated biphenyls (PCBs), a toxic substance released into the environment for over 70 years. The breakthrough could lead to the development of bioremediation technologies to tackle the pollutants.
A recent study published in The Lancet suggests that prenatal and postnatal exposure to polychlorinated biphenyls is associated with lower mental and motor development scores in infants. Conversely, a stimulating home environment can counteract this adverse effect.
Researchers will study the health impact of chemicals in fish on refugees' children, as well as educate communities about safe fishing practices. The center aims to address the effects of combined PCB-methyl mercury exposure.
A study found that prenatal exposure to DDE and PCBs increased the size of children at puberty, with boys growing taller and heavier and some girls becoming heavier for their heights. The findings suggest a potential link between environmental pollutants and childhood growth.
A large case-control study of nearly 1,000 Connecticut women found no significant association between PCBs or DDE exposure and breast cancer risk. The research suggests that previous studies on the topic have been inconclusive due to small sample sizes and lack of consideration for modifying factors.
A University of Southern California study found that DDT and PCBs are widely distributed in the Palos Verdes Shelf water column, leaching from sediments. The substances' concentrations decreased exponentially with distance from the ocean floor, indicating they're being transported by ocean currents.
Researchers find that native animals are more common in areas with native vegetation than in areas with exotic vegetation or grazing. They also discover that DDT may still be affecting reproduction of double-crested cormorants, while tree swallows can serve as sentinels for PCB contamination in aquatic environments.
A University of Georgia researcher's study found that many PCBs in the environment may not be as carcinogenic as previously believed. The project aimed to re-evaluate the toxicity of PCBs based on new scientific information and changes in cancer classification.
Researchers at Georgia Institute of Technology developed a novel experimental technique called Thermoiré to track circuit board warpage in real-time. This allows manufacturers to make design changes before production, reducing losses and increasing product reliability.
