“…Of most interest are nitrogen-substituted derivatives (NPAHs), oxygenated PAHs (OPAHs), methylated PAHs (MPAHs), and amino PAHs (APAHs). NPAHs form during the combustion cycle as a result of reactions with either HNO 3 or NO x and have been described previously (Sienra and Rosazza 2006;Zielinska and Samy 2006;Delhomme et al 2007;Hattori et al 2007). OPAHs may include carboxylate, hydroxy, dihydroxy, aldehyde, carboxaldehyde, ketone, and acetoxy functional groups and can be divided into two subgroups; carboxylated PAHs that contain one or more carbonyl oxygen(s) attached to the aromatic ring (ketones and quinones) and hydroxylated PAHs containing one or more hydroxyl groups.…”

Environmental context. Atmospheric aerosols have profound effects on the environment through several physicochemical processes, such as absorption and scattering of sunlight, heterogeneous gas-particle reactions and adverse effects on the respiratory and cardiovascular systems. Understanding aerosol atmospheric chemistry and its environmental impact requires comprehensive characterisation of the physical and chemical properties of particles. Results from mass spectrometry provide important new insights into the origin of atmospheric aerosols, the evolution of their physicochemical properties, their reactivity and their effect on the environment.Abstract. This manuscript presents an overview of the most recent instrument developments for the field and laboratory applications of mass spectrometry (MS) to investigate the chemistry and physics of atmospheric aerosols. A range of MS instruments, employing different sample introduction methods, ionisation and mass detection techniques are used both for 'online' and 'offline' characterisation of aerosols. Online MS techniques enable detection of individual particles with simultaneous measurement of particle size distributions and aerodynamic characteristics and are ideally suited for field studies that require high temporal resolution. Offline MS techniques provide a means for detailed molecular-level analysis of aerosol samples, which is essential to gain fundamental knowledge regarding aerosol chemistry, mechanisms of particle formation and atmospheric aging. Combined, complementary MS techniques provide comprehensive information on the chemical composition, size, morphology and phase of aerosols -data of key importance for evaluating hygroscopic and optical properties of particles, their health effects, understanding their origins and atmospheric evolution. Over the last few years, developments and applications of MS techniques in aerosol research have expanded remarkably as evident by skyrocketing publication statistics. The goal of this review is to present the most recent developments in the field of aerosol mass spectrometry for the time period of late 2010 to early 2012, which have not been conveyed in previous reviews.

“…11; PAHs may also be released via agricultural fires and cooking. The researchers have found out the characteristics of the precursor sources (i.e., whether they are pyrogenic or petrogenic) through the PAHs distributed in the sediments (Aboul-Kassim & Simueit, 1995;ATSDR, 1995;Zielinska & Samy, 2006).…”

Persistent Organic Pollutants (POPs) have a very long life and they persist in the environment for a very long time and have a long life in soils, sediments, air or biota. There has been a recent upsurge of interest in the development of low cost reliable measures which are required in order to detect and trace current concentration levels of persistent organic pollutants (POPs) as a result of increasing levels of accumulation within the living organism, transformation as well as toxicity making it ideal to examine the impact on the environment which has been the focus of this review. There are still debates that rage around the issue including relevance of some physio pathologic effects of POPs on the human body along with epidemiological and clinical effects on the human population. Hence in this review there is examination, debating and presenting of arguments in relation to the sources, properties and types of POPs in the atmosphere along with examining the toxicity, analytical techniques and monitoring of atmospheric and biological concentration of POPs in the human population.
