Environmental and human health impacts of volatile organic compounds: A perspective review.

Abstract Environmental sensitivity index (ESI), is an important factor in the planning process and delineation the different future scenarios along the coastal areas. The aim of this work is to develop ESI model, determine poly aromatic hydrocarbons sources and risk assessing. Studying the different factors; physical, biological sources or land uses and covers aid in elaborating the ESI map. ESI illustrates the most sensitive areas in Gulf of Suez and Mediterranean coastlines which are located nearby the outlets of drains, sea ports and industrial sites, especially of petrol activities. Nine locations were sampled in each of the two studied areas. A total of 18 samples were collected, however only 11 samples were selected for the determination of poly aromatic hydrocarbons (PAHs) according to the EPA 550 methods. The highest average concentrations of PAHs were Fluorine and Acenaphthylene in Gulf of Suez and Mediterranean Sea, respectively. The concentrations of individual PAHs were within the threshold limits of ERL, ERM and PEL suggesting no adverse biological effects. The ratios of Ant/Ant + Phe, Flu/Flu + Py and BaA/BaA + Chy indicated that most of the PAHs sources are of petrogenic sources (63.64%), and the rest (36.36%) are from petroleum combustion. PCA give indication to the correlation between different isomers ratios with the different LU/LC into two areas. The carcinogenic risk values were within the very low risk category (&lt; 10 − 6 ) for both adults and children. The most carcinogenic and mutagenic contributors were BkFlu and IP in Gulf of Suez and Mediterranean Sea, respectively.
