Air pollution is now recognized as the world's single largest environmental and human health threat. Indeed, a large number of epidemiological studies have quantified impacts population exposure to pollution. In previous studies, estimates at level not considered spatially- temporally varying populations present in study regions. Therefore, first it kind, we use measured activity patterns representing several million people evaluate population-weighted air on city-wide scale. Mobile wireless...
Groundwater quality analyses were carried out on samples from 262 private sources in the Republic of Ireland during period April 2008 to November 2010, with microbial assessed by thermotolerant coliform (TTC) presence. Assessment potential contamination risk factors was undertaken at all sources, and local meteorological data also acquired. Overall, 28.9% wells tested positive for TTC, analysis indicating that source type (i.e., borehole or hand‐dug well), bedrock type, subsoil groundwater...
Abstract An assessment of global groundwater quality is needed in response to the threats posed by anthropogenic and geogenic contaminants. This essay summarises challenges involved, including a large number potentially relevant water parameters, poor availability data many regions complex nature systems. Direct monitoring can sometimes be augmented indirect methods such as earth observations, involving citizen science. A new web portal being developed complement existing databases.
Based on the sampling of 262 private domestic wells in Ireland, mainly located High/Extreme vulnerability areas, a quantitative model was developed for prediction gastrointestinal infection risk attributable to verotoxigenic E. coli (VTEC) contamination Ireland. Models are based maximum likelihoods and predict an overall crude incidence rate 28.3/100,000 well users per annum; approximately 5-6 times higher than rates reported within Irish population up 40 current EU mean. Predicted (CIR)...
Traffic is a major source of urban air pollution that affects health, especially among children. As lower speed limits are commonly applied near schools in many cities, and different governments have policies on vehicle fleet composition, this research estimated how emissions affect quality primary school. Based data traffic, weather, background records Dublin from 2013, emission, dispersion models were developed to assess the impact composition changes against current conditions. Outside...
Ptaquiloside, along with other natural phytotoxins, is receiving increased attention from scientists and land use managers. There an urgent need to increase empirical evidence understand the scale of phytotoxin mobilisation potential enter into environment. In this study risk ptaquiloside drinking water was assessed by quantifying in waters at three abstraction sites across Ireland bracken fronds surrounding sites. We also investigated impact different management regimes (spraying, cutting...
Abstract Improving our understanding of groundwater quality threats to human health and the environment is essential protect manage resources effectively. This essay highlights some global challenges, describes key contaminant groups emerging concern, including antimicrobial resistance, discusses novel approaches assessing quality. Groundwater monitoring needs improve significantly in order effectively identify mitigate from historical, current future pollution.
Current Irish guidelines require a comprehensive site assessment of percolation area for wastewater disposal before planning permission is granted dwellings in rural areas. For to be deemed suitable, the subsoil must have value equivalent field saturated hydraulic conductivity range 0.08 4.2 m d(-1) using falling head test. A minimum 1.2 unsaturated also exist below invert receiving effluent from septic tank (or 0.6 secondary treated effluent). During 2-yr period, three-dimensional...
Abstract This paper summarizes the findings of a recent research project on groundwater contamination from leaking sewers, which was completed for Construction Industry Research and Information Association. Fifty‐four incidents were identified in England Wales combined questionnaire survey literature review. In addition to recorded incidents, poor quality many urban groundwaters suggests some effects sewers. Age is considered be most significant characteristic governing leakage sewers;...
A groundwater recharge map has been created for the Republic of Ireland. This provides important baseline information multiple purposes: aquifer water balance assessments using simple lumped models or distributed numerical models; assessment impact abstractions as required under European Water Framework Directive; and delineation source protection zones. The is derived from existing hydrogeological meteorological spatial datasets. main controls on include permeability thickness superficial...
