Enumerating actinomycetes in compost bioaerosols at source—Use of soil compost agar to address plate ‘mask

Taha, M. P. M.; Drew, Gillian H.; Tamer Vestlund, Asli; Aldred, David; Longhurst, Philip J.; Pollard, Simon J. T. (2007-07-01)

Actinomycetes are the dominant bacteria isolated from bioaerosols sampled at composting facilities. Here, a novel method for the isolation of actinomycetes is reported, overcoming masking of conventional agar plates, as ...
Evaluating the quality of bioaerosol risk assessments for composting facilities in England and Wales

Drew, Gillian H.; Jordinson, G. M.; Smith, M. A.; Pollard, Simon J. T. (Elsevier Science B.V., Amsterdam., 2009-07-01)

A critical evaluation of 44 environmental risk assessments for composting facilities, submitted in support of environmental permits or exemption from licensing is presented. Assessments were scored semi-quantitatively, ...
Identifying uncertainty in environmental risk assessments: the development of a novel typology and Its implications for risk characterisation

Skinner, Daniel J. C.; Rocks, Sophie A.; Pollard, Simon J. T.; Drew, Gillian H. (Taylor & Francis, 2014-12-31)

Environmental risk analysts need to draw from a clear typology of uncertainties when qualifying risk estimates and/or significance statements about risk. However, categorisations of uncertainty within existing typologies ...
Improving bioaerosol exposure assessments 1 - comparative modelling of 2 emissions from different compost ages and activities.

Taha, M. P. M.; Drew, Gillian H.; Tamer Vestlund, Asli; Hewings, G.; Jordinson, G. M.; Longhurst, Philip J.; Pollard, Simon J. T. (2007-07-01)

We present bioaerosol source term concentrations from passive and active composting sources and compare emissions from green waste compost aged 1, 2, 4, 6, 8, 12 and 16 weeks. Results reveal that the age of compost has ...
Modelling human exposures to air pollution control (APC) residues released from landfills in England and Wales

Macleod, Christopher; Duarte-Davidson, Raquel; Fisher, Bernard; Ng, Betty; Willey, David; Shi, Ji Ping; Martin, Ian; Drew, Gillian H.; Pollard, Simon J. T. (Elsevier Science B.V., Amsterdam., 2006-05-01)
