The debate about the human health effects of dioxin continues, even as the levels of dioxin measured in people have continued to decline from their peak 30 to 40 years ago. Increasingly, scientific studies have shown that humans are less sensitive to the effects of dioxin than some laboratory ...
Dioxin contamination in Vietnam has had a long-term impact on the environment and human health, particularly in hotspots of high contamination [1,2,3,4]. This has mainly been related to the use of herbicides, especially Agent Orange, which contains 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD...

For a long time, scientists considered genotoxic effects as the major issue concerning the influence of environmental chemicals on human health. Over the last decades, a new layer superimposed the genome, i.e., the epigenome, tremendously changing this p
There was previous knowledge that2,4,5-T can cause problems in humans, and they only mixed it with something more dangerous: “One chemical used to make Agent Orange was contaminates with a dioxin, TCDD” (Agent Orange.” UXL Encyclopedia of Science). Dioxins are very toxic to humans, ...
Urban pollution issues, both air and water, were tied into social interests/human health before gaining acknowledgement as purely environmental issues that had consequences for life other than humans. The intrinsic value of nature, with the exception of the wilderness preservation movement at the turn...

These bile-acid conjugates were also found in humans, and were enriched in patients with inflammatory bowel disease or cystic fibrosis. These compounds agonized the farnesoid X receptor in vitro, and mice gavaged with the compounds showed reduced expression of bile-acid synthesis genes in vivo. ...
