DOXIN 2017

International Symposium on Halogenated Persistent Organic Pollutants (POPs) – DIOXIN 2017 will be held on 20-25th August in Vancouver, Canada at the Sheraton Wall Centre.

The year 2017 marks the 37th anniversary of the Dioxin Symposia. In 1980, Otto Hutzinger organized the first symposium in Rome, Italy. Since then, annual symposia (except 1983) have been held in cities around the world. Over the past 37 years, there have been major advances in the analytical determination, and the understanding of the transport, fate and toxic behavior of these compounds. The year 2017 also marks the 150th anniversary of Canada. We will have numerous activities and celebrations showcasing Vancouver and Canada

This years conference will have over 60 sessions covering all expects of POPs and will include numerous special sessions, including new and emerging persistent organic pollutants (POPs) such as halogenated flame retardants and perflourinted chemicals.  Environmental Science: Processes & Impacts Advisory Board member, Stuart Harrad, will be presenting at the event.

Key Dates:

Abstract Deadline: 21st April 2017

Early Bird Registration: 30th June 2017

Call for Input: Grand Challenges and Opportunities for Environmental Engineering and Science for the 21st Century

To help guide the next generation of environmental engineers and scientists, the National Academies of Sciences, Engineering, and Medicine has appointed a committee of experts to conduct a study on Grand Challenges and Opportunities in Environmental Engineering and Science for the 21st Century.

Environmental challenges continue to multiply as the global population expands and as demands for clean water, food, and energy rise, all in the context of global climate change.  With expertise in a wide range of fields and with input from the scientific community, the committee will identify the biggest environmental challenges to be solved over the next several decades and comment on how education and training might be better aligned to address those challenges.

The committee slate is provisional, pending a 20-day comment period ending on March 29, 2017 and final approval.

 

                                                    Call for Input: What are the biggest challenges?

The committee invites the scientific community and the public to submit ideas about ambitious but achievable goals that harness science, technology, and innovation from environmental engineering and science to solve important national or global problems.  Submit your ideas here.

 

                                      First Public Meeting on May 4: Register Today!

The first public meeting will be held in Washington, DC and also on the web on Thursday, May 4, 2017 (agenda TBA).  Attendees will hear from committee chair Domenico Grasso of the University of Delaware and from the National Science Foundation and other sponsors about the goals of this effort.  The National Academy of Engineering (NAE) will also share insights into its highly successful Grand Challenges for Engineering study and campaign, upon which this new study is modeled. Register to attend today!

If you are interested in following the activities of this study, sign up for email updates on the study website and discuss the study on Twitter using #GrandChallenges.

Unexpected levels of monoterpenes found in UK homes

Overusing household cleaners may reduce indoor air quality

The air in some UK homes contains potentially harmful levels of volatile compounds due to residents overusing household chemicals without proper ventilation, new research shows.

Air quality research tends to focus on the outdoors. However, with homes becoming more insulated and energy efficient, and with people spending more time indoors, it’s worthwhile studying this air too.

Alastair Lewis’ team at the University of York and colleagues at King’s College London have measured the concentration of gaseous organic compounds in 25 UK homes to see how occupants’ activity can affect indoor air quality.

Emerging Investigators Series: Yu (Frank) Yang

 

Yu (Frank) Yang is an Assistant Professor at the University of Nevada, Reno, working in the Civil and Engineering Department. Prior to this, he completed both his undergraduate studies and PhD at Peking University, China. His current research interests include: the impact of global climate change on the fate of critical pollutants; the response of organic matter geochemistry to the temperature increases; and the colloid-facilitated reactive transport of insoluble radionuclides.

Read his Emerging Investigators article “Dual role of organic matter in the anaerobic degradation of triclosan” and find ourmore about Frank and his research in the interview below:

Are you within 10 years of receiving your PhD? Do you have an independent research career? Then you could be eligible for our Emerging Investigator Series! find out more at rsc.li/emerging-espi

 

Your recent Emerging Investigator Series paper focuses on the role of organic matter in the anaerobic degradation of triclosan. How has your research evolved from your first article to this most recent article?

My first research paper is about the human exposure to legacy pesticides (e.g. DDT) and their health risk. My Ph.D. studies and postdoctoral projects are mainly focused on the organic matter-mediated fate and transport of organic and inorganic pollutants. In this paper, we have found an interesting novel dual role of organic matter in the degradation of an emerging organohalide compound.

What aspect of your work are you most excited about at the moment?

In my research group, we are mainly working on the important environmental redox reactions, focusing on the degradation of organohalides, microbial assimilation and plant uptake of carbon nanomaterials, and stability of soil organic carbon. We are currently using lots of state-of-the-art technologies to study the transformation of organohalides and natural organic carbon, which is really exciting to us.

In your opinion, what is the biggest impact to the environment presented by antimicrobial agents?

Release of antimicrobial agents can induce the development of antimicrobial resistance, which is one of the biggest environmental problems.

What do you find most challenging about your research?

I would like to fully understand the degradation pathways of emerging organohalides and work out cost-effective removal strategies. Both are challenging tasks.

In which upcoming conferences or events may our readers meet you?

My group and I will present our work (6 talks and 3 posters) at American Chemical Society 2017 Spring Meeting (April 2-6, 2017, San Francisco). I am also chairing two symposia with my colleagues, with one for redox reactions and the other for nanomaterials.

How do you spend your spare time?

When I have spare time, I enjoy watching movies, playing chess, and spending time with my family.

Which profession would you choose if you were not a scientist?

Without science, probably I would become a high-school teacher.

Can you share one piece of career-related advice or wisdom with other early career scientists?

Have a good balance and be persistent. Balance between the crazy ideas and relatively “low-risk” projects, balance between pursuing grants and publishing papers, balance between research and teaching, and many others
