High-molecular-weight by-products of chlorine disinfection
For example, the most abundant high-molecular-weight DBP features detected in a chlorine-disinfected drinking water were identified as chlorinated and brominated 2,2,4-trihalo-5-hydroxy-4
2017 Guideline for High Blood Pressure in Adults - American
In persons ≥30 years of age, higher SBP and DBP are associated with increased risk for CVD, angina, myocardial infarction (MI), heart failure (HF), stroke, peripheral arterial disease, and abdominal aortic aneurysm. SBP has consistently been associated with increased CVD risk after adjustment for, or within strata of, SBP; this is not true for DBP.
Older Adults and Hypertension: Beyond the 2017 Guideline
DBP 70-79mmHg. In November 2017, the American College of Cardiology/American Heart Association (ACC/AHA) hypertension guideline introduced new definitions for BP management ( Table 1 ). Blood pressure is now categorized as normal, elevated, and stage 1 or 2 hypertension. Normal BP is defined as
TIC-Tox: A preliminary discussion on identifying the forcing
The objective of this study was to define a distribution map assigning the forcing agents involved in DBP-mediated toxicity of disinfected water. 1. Materials and methods The data to define the forcing agents of DBP-induced mammalian cell cytotoxicity are derived from two sources.
Synergistic effects of quenching agents and pH on the
Quenching agents (QAs) are widely used in order to prevent the additional formation of disinfection by-products (DBPs) during the sample holding time. In addition, DBP levels are usually stabilized by adjusting the pH of water samples. Previous studies have mostly focused on the individual effects of QAs or of pH on the stability of DBPs in water samples. Considering that disinfectant
