airmid healthgroup Air Filtration & Biomedical research representatives will be attending the International Filtration Conference in Philadelphia, USA during the 14th – 15th November.
Esmeralda Herrero graduated from University College Dublin (UCD) with a BSc in Pharmacology and completed a PhD in Microbiology in University College Dublin. Her research investigated bacterial proteases and their role in prion decontamination and was filed into a UK patent in 2015. Following her PhD, Esmeralda worked for a year as research and development scientist for a novel biotech company before her role as scientific officer in virology in airmid healthgroup.
Esmeralda has over 5 years research experience in mammalian cell culture, molecular biology, bacterial culturing, infectious assays, protein purification, protein biochemistry and laboratory management
Tristan graduated from the University of Leeds with a BSc in Microbiology. During his degree, Tristan completed a one-year internship at a pharmaceutical company where he gained experience of working in an industrial laboratory. Tristan moved to Ireland in 2014 after choosing to study for a PhD at University College Dublin. The PhD research used molecular biology techniques to study infectious disease, specifically host-virus interactions. Tristan recently graduated from his PhD and joined the virology team at airmid healthgroup in the spring of 2019.
Kevin is in his third year at DCU where he has been studying Genetics and Cell biology. He is working in the Environmental Chambers under the supervision of Jake Behan.

Last month airmid attended the 2012 Annual General Meeting of the European Feather and Down Association in Dublin. The purpose of the association is to promote the interests of the European members of the bedfeather and feather-filling industry and their suppliers. In addition, it pursues the targets of making a contribution towards promoting fair business dealings and transactions, of informing its members of European quality regulations, and of encouraging the compliance with such regulations.
For this blog entry, we discuss the occurrence of "Popcorn workers lung" attributed to diacetyl inhalation, following the recent legal proceedings of a Bronchiolitis obliterans (BO) sufferer who contracted the respiratory disease following exposure to diacetyl from Popcorn. BO is an obstructive respiratory disease, whereby the bronchioles are obstructed by tissue damage and aberrant epithelial repair. The result is a narrowing of the bronchioles, restricting normal respiratory function. This should be of concern to managers and safety officals of manufacturing plants producing diacetyl and whose employees or consumer base may be at risk from exposure.
As a world leader in Environmental Research, Development & Testing, airmid healthgroup recognises the importance of being an ISO 17025 accredited laboratory. The benefits include:
Recent studies conducted on vacuum cleaner emissions, have vacuum cleaners as a potential source of indoor exposure to airborne allergens, bacteria and other pathogens. In this blog post we review the issues around this occurrence and the steps manufacturers of vacuum cleaners can take to ensure their products meet certification standards, in particular the asthma & allergy friendly certification standard. As an accredited immunoassay testing facility airmid healthgroup is a designated laboratory for the program.
The testing of vacuum cleaners and similar domestic electrical appliances such as air cleaners involves the use of "test-dust"; inert particles consisting of silicon dioxide, aluminium, iron and sodium oxides. It is used to mimic typical household dust, which is composed of a mixture of fibres and particles of varying sizes and compositions. Sources of which include skin, mites, soil, heating emissions and pollen grains. In this blog post, we talk to Dr. Angela Southey, a lead researcher at airmid healthgroup, about a recent study she conducted and presented at the prestigious 13th International Conference on Indoor Air Quality and Climate in Austin, Texas comparing the characteristics of ISO fine test dust to real house dust.
This blog post follows an interview format with Angela Southey PhD at the test facility at airmid healthgroup and offers a very valuable insight on the subject.
ASHRAE 52.2 is a method of testing general ventilation air cleaning devices to determine their removal efficiency as a function of particle size. It is a method that determines the ability of an air filter to remove particles on the basis of specific particle sizes ranging between 0.3 to 10 microns. A central feature of ASHRAE 52.2 is the incorporation of the Minimum Efficient Reporting Value (MERV) for each filter tested. Angela Southey is the head of the environmental test chamber at airmid healthgroup. In this interview, we ask Angela about Airmid’s new ASHRAE 52.2 test duct, its functional association with the Environmental Test Chamber and the importance this facility has for HVAC testing, MERV testing and its potential for contract research.

For this blog entry we are covering the topic of Legionnaires' disease following the outbreak in Edinburgh last month and more recently the outbreak in Stoke-on-Trent in England. Scotland's Health Secretary Nicola Sturgeon reported that the number of confirmed and suspected cases of Legionnaires' disease in Edinburgh had risen to 40. Air Quality professionals suspected the source of the Edinburgh outbreak was environmental contamination and early indications suggest it was the result of a contaminated cloud emitted from a cooling tower in the south west of the city. The source of the outbreak in Stoke-on-Trent has not yet been identifed.
Over recent years, airmid healthgroup has become a market leader in the assessment of airborne bio-particulate load in indoor spaces. Unique services are provided to clients in both state-of-the-art large scale chambers or in “field” situations, i.e. environmental studies in homes, offices, and other places where people congregate.
There is a bewildering array of ISO and ASTM antimicrobial surface validation studies and a whole host of biocidal activity testing available. It can be very complex for companies to navigate their way through this and the results they get may not always translate into market valuable data. Control of indoor pathogens on surfaces and in the air is a highly topical issue, so we asked John Fallon PhD, Head of Microbiology at airmid healthgroup, to talk us through some of the testing we do at the laboratory and the relevance of this testing.
