The Interrelated Pollution Characteristics of Atmospheric Speciated Mercury and Water-Soluble Inorganic Ions in Ningbo, China

open access: yesAtmosphere, 2023
Atmospheric mercury and water-soluble inorganic ions (WSIIs) are commonly observable airborne pollutants in the atmosphere that may have similar emission sources.

Species-specific effects of elevated ozone on wetland plants and decomposition processes [PDF]

open access: yes, 2010
Seven species from two contrasting wetlands, an upland bog and a lowland rich fen in North Wales, UK, were exposed to elevated ozone (150 ppb for 5 days and 20 ppb for 2 days per week) or low ozone (20 ppb) for four weeks in solardomes.

Role of histamine in the inhibitory effects of phycocyanin in experimental models of allergic inflammatory response

open access: yesMediators of Inflammation, 2002
It has recently been reported that phycocyanin, a biliprotein found in the blue-green microalgae Spirulina, exerts anti-inflammatory effects in some animal models of inflammation.

An Ozone-Modified Refractive Index for Vertically Propagating Planetary Waves [PDF]

open access: yes, 2007
[1] An ozone-modified refractive index (OMRI) is derived for vertically propagating planetary waves using a mechanistic model that couples quasigeostrophic potential vorticity and ozone volume mixing ratio. The OMRI clarifies how wave-induced heating due

Doctors’ professional identity and socialisation from medical students to staff doctors in Japan: narrative analysis in qualitative research from a family physician perspective

open access: yesBMJ Open, 2020
Objective Becoming a doctor involves transforming a lay person into a medical professional, which is known as professional socialisation. However, few studies have clarified differences in the professional socialisation process in detail. The aim of this

Protection by ozone preconditioning is mediated by the antioxidant system in cisplatin-induced nephrotoxicity in rats

open access: yesMediators of Inflammation, 2004
Background: Acute renal failure is a dose-limiting factor of cisplatin chemotherapy. Here, we show the protective effect of ozone oxidative preconditioning against cisplatin-induced renal dysfunction in rats.

Stratospheric ozone depletion [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 1991
Solar ultraviolet radiation creates an ozone layer in the atmosphere which in turn completely absorbs the most energetic fraction of this radiation. This process both warms the air, creating the stratosphere between 15 and 50 km altitude, and protects the biological activities at the Earth's surface from this damaging radiation.

Tropospheric ozone in CMIP6 simulations

open access: yesAtmospheric Chemistry and Physics, 2020
. The evolution of tropospheric ozone from 1850 to 2100 has been studied using data from Phase 6 of the Coupled Model Intercomparison Project (CMIP6). We evaluate long-term changes using coupled atmosphere–ocean chemistry–climate models, focusing on the ...
