The most common subclass of POM is the polycyclic aromatic hydrocarbons (PAHs). These compounds contain only carbon and hydrogen. PAHs are a large group of organic compounds with two or more fused aromatic (benzene) rings.

Low-molecular-weight PAHs (two and three rings) occur in the atmosphere predominantly in the vapour phase, whereas multi Cited by: Polycyclic Hydrocarbons and Cancer, Volume 3 explores the link between polycyclic aromatic hydrocarbons (PAHs) and cancer based on research in the fields of chemistry, biology, and the medical and social sciences.

Short for polycyclic aromatic hydrocarbons, PAHs describe chemicals that are often found together in groups of two or more. PAHs are found naturally in the environment but they can also be man-made.

In their purest form, PAHs are solid and range in appearance from colorless to white or pale yellow-File Size: KB. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled.

This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. Chapter Polycyclic aromatic hydrocarbons (PAHs) General description Polycyclic aromatic hydrocarbons (PAHs) are a large group of organic compounds with two or more fused aromatic rings.

They have a relatively low solubility in water, but are highly lipophilic. Most of the PAHs with low vapour pressure in the air are adsorbed on Size: KB. implicating PAHs as an inducer of cancerous and precancerous lesions is becoming overwhelming, and this class of substances is probably a major contributor to the recent increase in cancer rates reported for industrialized nations (Cooke and Dennis ).

PAHs were the first compounds known to be associated with carcinogenesis (Lee and Grant ). Polycyclic Aromatic Hydrocarbons (PAHs) Factsheet. th edition. Donata Lerda. JRC - File Size: KB. The atmospheric persistence of PAHs has received considerable attention in recent years and continues to be actively investigated.

Two extreme situations can be envisioned. In the absence of any chemical interaction, the lifetime of PAHs adsorbed onto particles will depend solely on physical characteristics—the size of the carrier particle and scavenging processes, including wet and dry.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants generated primarily during the incomplete combustion of organic materials (e.g., coal, oil, petrol, and wood).

Many PAHs have toxic, mutagenic, and/or carcinogenic functions. PAHs are highly lipid soluble which lead to a fast absorption by the gastrointestinal tract of marine : Ayoub Baali, Ahmed Yahyaoui.

Naphthalene, with its two rings, is considered the simplest polycyclic aromatic hydrocarbon by US EPA and CDC for policy contexts. Other authors consider PAHs to start with the tricyclic species phenanthrene and anthracene. PAHs are not generally considered to contain heteroatoms or.

PAHs are primarily emitted by anthropogenic activities, and although some natural and secondary sources of these contaminants are discussed, the focus of this chapter is the major primary sources to the atmosphere.

We examine the thermal reactions involved in the release of PAHs, and include details of some important non-combustion by: PAHs may be exposed through contact with contaminated air, water, and soil.

For more information on human exposure to PAHs, see Chapter 5. HOW CAN POLYCYCLIC AROMATIC HYDROCARBONS ENTER AND LEAVE MY BODY. PAHs can enter your body through your lungs when you breathe air that contains them (usually stuck to particles or dust).

Polycyclic aromatic hydrocarbons (PAHs) are class of chemicals that can exist in more than different combinations and are among the most ubiquitous pollutants in the natural environment. Many PAHs are considerably toxic to aquatic species, such as pyrene, which exhibits considerable toxicity even at low levels of exposure.

Furthermore, some are even carcinogenic, such as benzo[a]pyrene.
