Development of a simple analytical method for determining trihalomethanes in beer using a headspace solid-phase microextraction technique

open access: yesQuímica Nova, 2013
We developed a simple, rapid, and solventless method for analyzing trihalomethanes in beer samples using headspace solid-phase microextraction. The effects of varying experimental parameters, such as extraction temperature and time, addition of sodium ...

Vulnerability assessment to trihalomethane exposure in water distribution system. [PDF]

open access: yes, 2018
Chlorination is an effective and cheap disinfectant for preventing waterborne diseases-causing microorganisms, but its compounds tend to react with the natural organic matter (NOM), forming potentially harmful and unwanted disinfection by-products (DBPs)

Profiles of dissolved organic matter and haloacetic acid formation potential in drinking water treatment by a comprehensive fractionation technique [PDF]

open access: yes, 2012
A comprehensive fractionation technique was applied to a set of water samples obtained along a real drinking water treatment plant with ozonation and granular activated carbon (GAC) treatment to obtain detailed profiles of dissolved organic matter (DOM ...

Sensitivity Analysis of a Proposed Model for Removal Efficiency of Trihalomethanes (THMs) Using Spray Aeration [PDF]

open access: yes, 2013
Trihalomethanes (THMs) form in drinking water treatment systems as a byproduct of chlorination and are problematic from a public health perspective due to their carcinogenic potential and their potential for additional formation throughout distribution ...

Évolution de la qualité de l'eau dans le réseau de distribution de la ville de Montréal [PDF]

open access: yes, 1997
Dans la présente étude, nous montrons l'évolution de l'eau dans un réseau de distribution. Ce réseau a été construit dans les années 70 à l'aide de conduites d'acier ou de fonte ductile munies d'un revêtement intérieur de ciment.

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found

Placental Abruption and Perinatal Mortality: Abnormal Placentation and Spontaneous Abortion as Contributors to Left Truncation Bias

open access: yesPaediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Generally, studies in perinatal epidemiology restrict cohort entry to 20 weeks of gestation, but exposures and outcomes may occur earlier. This restriction may introduce left truncation bias. Objectives To examine the impact of left truncation bias when estimating the causal effect of abruption on perinatal mortality in the context ...
