Critical analysis and mapping of research trends and impact assessment of polyaromatic hydrocarbon accumulation in leaves: let history tell the future.

The article is basically an attempt to provide a consolidated report on impact assessment and trends in research pertaining to accumulation and curbing the menace of polyaromatic hydrocarbon (PAH) accumulation in leaves. Emphasis is given to understand the consequences of the fact that edible/medicinal plants cultivated in PAH contaminated soil or close to such places which are potential liberators of PAHs can virtually act as transporters for direct PAH entry into biological systems. An attempt has been made to predict the future by digging out golden facts from history.
