Funding Success!
May 2013: Dr Hartl, in collaboration with coleagues in the Centre for Marine Biodiversity &
Biotechnology in the School of Life Sciences, as well as colleagues in the School of
Engineering and Physical Sciences at Heriot-Watt, has securred a £2,000 grant from
the Heriot-Watt Crucible V Interdisciplinary Research Fund to kick-start research in to
marine microplastic metrology.




                                                                            Heriot-Watt Crucible V




April 2013: The winning Crucible team at the final event brought together researchers from Heriot-
Watt University (Dr Mark Hartl, School of Life Sciences and Dr Paul Dalgarno, School of Engineering
& Physical Sciences) and University of Edinburgh (Dr Maria-Chiara Ferrari, School of Engineering
and Dr Stephen Moggach, School of Chemistry) in a project called "Tragic Plastic" which aims to
reduce the amount of plastic pollution in the marine environment through development of an
automated microplastic particle detection system. Read more about the Heriot-Watt Crucible V.




January 2013: Funding Success! We gave been awarded access to the Nanocharacterisation
facility (FENAC) in Birmingham, funded by NERC. Virginia Echevarri Bravo will be studying
the interaction between Ag nanoparticles and estuarine bacteria. Grant value: £24,000.



November 2012: Omar Alharbi (second from left) has successfully defended his thesis on
the ecotoxicological impact of corrosion inhibitors used in the offshore oil industry. His
project was supervised by Dr Hartl and Dr Steve Grigson. External examiner was Dr Trevor
Telfer from Stirling University. Internal examiner was Dr Liz Dyrynda.







September 2012: Top: Iain Hannah, PhD Student in Dr Hartl's lab (co-supervised by Prof Teresa
Fernandes and Prof Nik Christofi), won best ePoster for his work on the impact of nanosilver
particles on the bacteria of waste-water treament plants. Centre: Virginia Echavari, PhD
student in Dr Hartl's lab, presented her ePoster on the impact of nanosilver particles on estuarine
microbial communities. Bottom: Dr Hartl presented work conducted by PhD student Majed Al-Shaeri
on the impact of single-walled carbon nanotubes on marine algae.

July 2012: Dr Mark Hartl, as President of the Physiology Section of the American Fisheries Society,
chaired the plenary session at the 10th International Congress on the Biology of Fish. There were
four excellent talks from Dr Jonathan Wilson, Dr Peggy Biga, Dr Suzie Curry and Prof Lluis Tort (top).
Also Prof Carl Schreck gave an inspiring talk following the Award of Excellence in Fish Physiology
(second from top). Dr Brian Small, incoming Physiology Section President, presented Dr Hartl with a
certificate of appreciation for his Tenure 2010-2012 (centre). Student delegates receiving travel
buraries sponsored by an NSF grant and the AFS Physiology Section (second from bottom) Dr Lynn
Wever, Prof Chris Kennedy and Dr Hartl organized and chaired the toxicology symposium.





June 2012: Virginia Echavarri Bravo (r) presented her work on the ecotoxicological impact
of silver nanoparticles on estuarine microbial communities to the School of Life Sciences's
Nanosafety Group. Virginia is currently 18 months into her PhD in Dr Hartl's lab and has
recently been assissted by intern Océane Guillemet.

May 2012: Omar Alharbi, PhD student in Dr Hartl's lab, presented his work on the ecotoxocology
of oilfield chemicals at the 6th SETAC World Congress in Berlin, 20-24th May. Session ET11A -
Marine environmental chemistry and ecotoxicology





Funding success!
May 2012: Dr Mark Hartl, Prof Teresa Fernandes and Dr Tony Gutierrez have securred £30,000
from CREW - Centre of Expertise for Waters, for a review of emerging contaminants of concern
in waters: sources, impacts, risks and monitoring of water-related ‘known-unknowns’, in particular
engineered nano-particles, and primary and secondary micro-plastics.





May, 2012: Dr Hartl co-organised and co-chaired the Fish & Fisheries - Natural & Emerging Anthropogenic
Challenges theme at the World Fisheries Congress, 7-11 May, 2012, EICC, Edinburgh. The theme included
sessions on Land Use and Eutrophication, Ocean Acidification and Mining, Dams and Water Diversions,
Marine Renewable Energy, Toxics, Tsunamis and Fisheries. The sessions attracted over 500 delegates
spread over 3 days. Details of the Sessions:
