Researchers reporting in Environmental Science & Technology measured 60 DBPs in three types of tea, unexpectedly finding lower levels in brewed tea than in tap water. However, they also detected many unknown DBPs with uncertain health effects.
LEDs are commonly used for sterilization, and in the continued effort to combat the coronavirus pandemic, LEDs can also help inactivate SARS-CoV-2. A team in Pakistan designed far-ultraviolet LEDs at a targeted wavelength of 222 nanometers, chosen both for its ability to inactivate the virus and for being safe on human skin. They based their design on the material aluminum gallium nitride, part of a set of materials called III-nitrides which are efficient, inexpensive, and environmentally friendly.
Researchers reporting in ACS’ Environmental Science & Technology have found that using a complementary form of disinfection, known as copper-silver ionization (CSI), can decrease disinfection byproducts and cell toxicity of chlorinated swimming pool water.
A new peer-reviewed study validates the effectiveness of Xenex Disinfection Services’ LightStrike robot in quickly deactivating SARS-CoV-2 on surfaces, and explores the implications for reducing the risk of virus transmission everywhere that people work, travel, play and live.
They found that gently heating N95 masks in high relative humidity could inactivate SARS-CoV-2 virus trapped within the masks, without degrading the masks’ performance.
PurpleSun designs and manufactures hospital grade mechatronic systems that are user friendly and provide a special type of Focused Multivector Ultraviolet (FMUV) light technology, for the purpose of disinfection in 90 seconds.
Portable disinfection chambers that use ultraviolet (UV) light to inactivate virus particles could allow emergency medical technicians, police officers, healthcare workers, pharmacy technicians, and others to quickly disinfect their personal protective equipment (PPE) as they need it.
A new study shows that ozone gas, a highly reactive chemical composed of three oxygen atoms, could provide a safe means for disinfecting certain types of personal protective equipment that are in high demand for shielding health care personnel from Covid-19.
Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden “biofilms” that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
A cost-effective strategy for health care systems to offset N95 mask shortages due to COVID-19 is to switch to reusable elastomeric respirator masks.
