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. ...
The presence of host cell proteins (HCPs) in therapeutic protein drugs can have adverse effects on the production process and product performance. To effectively assess and control the risks associated with HCPs in therapeutic protein products, it is crucial to develop methods that can identify and monitor all HCP components. Traditional Methods and their ...
If you are associated with the fragrance industry or are interested in fragrances, you have most likely heard of IFRA. The International Fragrance Association (IFRA) is the global body that represents the fragrance industry. IFRA plays a vital role in ensuring that the fragrances produced and used worldwide are safe for people and the environment. This blog will outline what you need to know ...

The assessment of site conditions and the development of a conceptual site model (CSM) is crucial for the applications of this policy. ...
It's hard to miss the headlines. The recent outbreak of novel coronavirus disease (COVID-19) has dominated news cycles in recent months. But what information do we have that is related to coronaviruses in water and wastewater systems? And what can water- and wastewater-system operators do to protect public health? Modern water and wastewater treatment systems play an important role in public ...
Soil Generic Assessment Criteria for Human Health Risk Assessment is a technique used to examine the dangers which result from the release of pollutants into the land. ...
The fragrance industry is constantly evolving, with new regulations and standards being implemented to ensure consumer safety. One significant amendment that has captured the attention of fragrance professionals is the IFRA 49th Amendment. In this blog, we will delve into the details of this amendment and explore its key implications. Understanding the IFRA 49th Amendment is crucial for anyone ...
Burya holds a Ph.D. in analytical chemistry from the Ohio State University and will support clients in all stages of product development, from assessing the toxicology and regulatory profiles of new substances, performing quantitative risk assessments, and navigating state and federal regulations, to guiding teams through complex ...
This study assessed the risks posed by noroviruses (NoVs) in surface water used for drinking, domestic, and recreational purposes in South Africa (SA), using a quantitative microbial risk assessment (QMRA) methodology that took a probabilistic approach coupling an exposure assessment with ...
The study presents the methodology and its adaptation and use for the given context, in order to assess risks and to support stakeholders in improving the current sanitation system and validate the design of an improved one. First results of the application of the methodology, obtained in one of the four peri-urban wards of Iringa, demonstrated its efficacy and ...
The volume of water ingested by swimmers while swimming is of great interest to individuals who develop risk assessments using quantitative microbial risk assessment or epidemiological approaches. ...
This paper recommends the development of specific regulatory or design criteria, including a complete quantitative risk assessment framework for the evaluation and operation of MAR systems. ...
The minutes indicate that the SAP has significant concerns with EPA’s proposal to use the biomonitoring chlorpyrifos data from the CCCEH epidemiology studies to establish a point of departure (PoD) for chlorpyrifos risk assessment. The minutes state: “Because many uncertainties cannot be clarified, the majority of the Panel does not have confidence ...
This study assessed the contamination of Escherichia coli, in lettuce grown with treated domestic wastewater in four different irrigation configurations: open spray, spray under plastic sheet cover, open drip and drip under plastic sheet cover. ...
Worldwide, high incidences of cryptosporidiosis and giardiasis are attributed to livestock waste. Quantitative microbial risk assessment can be used to estimate the risk of livestock related infections from Cryptosporidium parvum and Giardia lamblia. The objective of this paper was to assess the occupational ...
Quantitative microbial risk assessment (QMRA), the assessment of microbial risks when model inputs and estimated health impacts are explicitly quantified, is a valuable tool to support water safety plans (WSP). ...
Up to date there are no studies on phytotoxic effects of functionalized halloysite (f‐HNTs). To develop a quantitative risk assessment model for predicting the potential impact of halloysite nanotubes supported palladium nanoparticles (HNT‐PdNPs) on plant life, we investigated their effect on seed germination, seedling development and mitotic ...
While traditional application of quantitative microbial risk assessment (QMRA) models usually stops at analyzing the microbial risk under typical operating conditions, this paper proposes the use of scenario-based risk assessment to predict the impact of potential challenges on the expected ...
The disease burden, expressed by disability-adjusted life year (DALY) was evaluated and compared with the infection risk obtained by quantitative microbial risk assessment. Findings showed that the disease burden due to road flushing was highest compared to the other pathways. For the different pathogens, E. coli was the leading ...
