The team analysed the women's diets, estimating their dioxin intake and following them for 15 years on average to look for differences in the amount of dietary dioxins in those who developed breast cancer. (cancerresearchuk.org)

Dioxins are also a contaminant or byproduct of nearly every chemical process involving chlorine. (genesisradiobirmingham.com)

People are exposed to dioxins via their diet, and the main sources are animal products such as fish, dairy products and meat. (bellona.org)
People are exposed to dioxins primarily by eating meat, fish, and dairy products, especially those high in fat. (delphiforums.com)

PVC is burned in every house fire, trailer fire, car fire and in the incineration of municipal and industrial waste," Coppolino further reports. (genesisradiobirmingham.com)

Students gaining experience in the above areas would be well-suited for employment related to the chemical aspects of environmental biotechnology (analytical techniques, purification, characterization, utilization, downstream processing, production) and this would be complementary to the engineering and molecular biological aspects of the field.

Risk Characterization of Dioxin and Related Compounds,' dated March 7, and May 2, 1994. (science-bbs.com)

The International Agency for Research on Cancer, part of the World Health Organization, determines that the most potent form of dioxin is a class one carcinogen. (issuesandalibis.org)

Dioxin" can also refer to 1,4-dioxin or p-dioxin, the basic chemical unit of the more complex dioxins. (wikipedia.org)
Nick Edwards, a clinical scientist at Guy's and St Thomas' Hospital in London, said: "Chloracne is a side effect of dioxin exposure but I have not heard of dioxins being used as a malicious chemical agent in this way. (bbc.co.uk)
We have broadened the scope of applicability by developing two, separate chemical "front-ends" for the enzyme-based process. (uwindsor.ca)
The products of both of these chemical processes are readily treated by the enzyme-based process. (uwindsor.ca)
Dioxin quantitative chemical analysis require costly and sophisticated methods only available in few laboratories worldwide. (veterinariadigital.com)
similar toxins are, but dioxin per se is a byproduct of other chemical processes or a degradation byproduct. (genesisradiobirmingham.com)
But due to still fairly recent although insurmountable scientific knowledge of 210 different chemical compounds known as dioxin and their numerous impacts on the environment, including risk to human health, environmental groups in Michigan believe the site of the new facility could pose more danger than it's worth. (review-mag.com)
Producers of chemical and industrial products understand the importance of using heavy-duty, durable containers to guarantee liquids and powders are safely contained.Chemical bottles come in a variety of materials like impact-resistant plastic as hdpe bottle. (dioxin2015.org)

Dioxin Shenanigans: Why the is EPA Afraid of Independent Peer Review? (nationalcenter.org)

And a new study, published today in the journal Breast Cancer Research , looks at dioxins in our diet and breast cancer risk. (cancerresearchuk.org)
But studies looking at dioxins and cancer aren't perfect. (cancerresearchuk.org)
What these studies do tell us is that in principal, certain dioxins can cause cancer - but principal and practice can differ. (cancerresearchuk.org)
So how does the latest study fit into the bigger picture on dioxins and cancer? (cancerresearchuk.org)
But in fact, Johns Hopkins have refuted the claims saying that there's no good evidence that dioxins are even present in the plastic used in water bottles, and there's no convincing scientific evidence to back up a link between using them and developing cancer. (cancerresearchuk.org)
