ELISAEnzyme-linked immunosorbent assay (ELISA) is the standard method for HCP detection because it provides quick, quantitative results. However, it relies on the availability and specificity of antibodies and may not detect all HCPs.2. Mass SpectrometryMass spectrometry provides a more comprehensive HCP analysis method, allowing researchers to identify and ...
The impact of varying biosolids holding times and other processes on STH using Ascaris as the reference STH pathogen was examined in this study using a quantitative risk analysis approach. Risk modelling of the potential human health impacts from the presence of Ascaris ova in biosolids was undertaken for discrete holding periods ...
The report uses a theoretical model of a typical drainage basin, but the approach could be applied to many of the drainage basins managed by the holding company for water and wastewater in Egypt. This study set out to assess the relative health impacts of different wastewater management strategies on health in the Nile delta region using an approach similar to that used in the Ghana. The ultimate ...
However, forecasts predict that solar energy will take up to 70% of global energy mix by year 2100. Solar energy has embedded risks, e.g., social, geopolitical, health-related, etc. These risks should be addressed in advance to prevent negative consequences but little research has addressed systemic risks of solar energy use growth. The paper ...
There is good reason to anticipate increased demand for sustainable and responsible investments from both retail and large institutional investors. Increasing interest in forestry may come from both a financial and general sustainability standpoint, and from a carbon perspective, because trees are a critical part of any successful climate change strategy. We develop the true sustainable financial ...
This does not rely solely on quantitative modelling, although model results are used in the analysis. Current approaches to risk analysis and quantitative forecasting are problematic since the systems addressed and their dynamics are not well understood, assumptions are often non-transparent, and necessary data ...
A quantitative microbial risk analysis—Monte Carlo method was used to estimate norovirus and Ascaris infection risks to urban farmers in developing countries watering their crops with wastewater. ...
A quantitative microbial risk assessment was applied to evaluate the microbial risks of the Accra Urban Water System (AUWS). The exposure assessment was based on the count of indicator organisms in waste water from open roadside drains and in water and sand samples from the beach. The predicted total disease burden generated in a representative catchment of the AUWS (Odaw Catchment) was 36,329 ...
Four estimators of annual infection probability were compared pertinent to Quantitative Microbial Risk Analysis (QMRA). A stochastic model, the Gold Standard, was used as the benchmark. ...
At any particular refinery unit, the likelihood of a major explosion is about 1 in 2,000 years [Ref. 1]. The explosion risk to people inside plant buildings will depend upon the type of building construction, the location, the plantprocesses and materials. A quantitative analysis can establish where risk is intolerably high and ...
The review of literature and computer models described in Part 1 of this paper led the authors to conclude that a quantitative hazard assessment methodology does not exist, in holistic terms, for landfill leachate. ...
Quantitative Risk Assessment (QRA) models have been used to assess the potential human exposure to, and assist in devising risk management strategies for, many foodborne hazards, including pathogenic bacteria, viruses and parasites. ...
In the United Kingdom, the Safety Case is “king.” Elsewhere, quantitative risk analysis (QRA) is widely used during the design process to ensure that fire and explosion risk areas are identified and either inherently safer measures are integrated into the design or appropriate “life-cycle managed” safety critical elements are ...
The precautionary principle is in sharp political focus today because firstly the nature of scientific uncertainty is changing, and secondly there is increasing pressure to base governmental action on allegedly more "rational" schemes, such as cost-benefit analysis and quantitative risk assessment. The precautionary principle has been criticised ...
Environmental Protection Agency (EPA) are often conservative and can result in an overestimate of the potential risk. The scope of this work is to perform an uncertainty analysis on the standard Superfund residential scenario risk equations using available statistical information for the uncertain exposure parameters. ...
