Heterogeneous reactions of particulate matter-bound PAHs and NPAHs with NO3/N2O5, OH radicals, and O3 under simulated long-range atmospheric transport conditions: reactivity and mutagenicity. [PDF]

, 2014
The heterogeneous reactions of ambient particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs (NPAHs) with NO3/N2O5, OH radicals, and O3 were studied in a laboratory photochemical chamber. Ambient PM2.5 and PM10 samples were

Evolution of PAHs in photodissociation regions: Hydrogenation and charge states

, 2013
Various studies have emphasized variations of the charge state and composition of the interstellar polycyclic aromatic hydrocarbon (PAH) population in photodissociation regions (PDRs). We aim to model the spatial evolution of the charge and hydrogenation

PAHs in protoplanetary disks: emission and X-ray destruction [PDF]

, 2012
We study the PAH emission from protoplanetary disks. First, we discuss the dependence of the PAH band ratios on the hardness of the absorbed photons and the temperature of the stars.

Biotic and abiotic risks of soil biochar treatment for food safety and human health

Acta Universitatis Sapientiae: Alimentaria, 2020
Pyrolysis technology facilitates the heating of organic waste biomass in a very low oxygen environment to temperatures over 400 °C. The high carbon content and surface area of the char produced via slow pyrolysis makes it suitable for a range of purposes

Sorption of PAHs to microplastic and their bioavailability and toxicity to marine copepods under co-exposure conditions.

Environmental Pollution, 2019
Organic chemical pollutants associated with microplastic (MP) may represent an alternative exposure route for these chemicals to marine biota. However, the bioavailability of MP-sorbed organic pollutants under conditions where co-exposure occurs from the

Cardiovascular Risk Factors Among Young Ischemic Stroke Patients Admitted at a Tertiary Care Hospital: An Observational Study

Journal of Nepal Medical Association
Introduction: Stroke in young adults (aged 15-49 years) is an increasingly recognized public health concern in both developed and developing nations. While traditional stroke occurs predominantly in older populations, the incidence in younger age groups
