Abstract

The bioaccumulation of metalloids especially arsenic (As) concentrations in urban and suburban environments and bioaccumulation of As in natural and exotic tree and shrub species are not well-documented. One of the most significant sources of As are vehicular emissions and coal combustion. The bioaccumulation of As in some natural and exotic tree and shrub species in Samsun and Atakum in Central Black Sea Region of Turkey is studied. Most of the studies about As pollution were carried out in heavily polluted environments such as lead smelters. However, high As concentrations were found for some natural and exotic tree and shrub species in urban and suburban environments in this study. It has been found that M. grandiflora twigs had the highest As concentrations in all of the studied species. Leaf As concentrations were found to be high in E. camaldulensis, P. abies, A. cyanophylla, C. vitalba, and L. vulgare as compared to twigs and flowers, while twigs of O. europaea and M. grandiflora had high As concentrations in Samsun center. E. camaldulensis and A. cyanophylla had high As concentrations in their leaves in Atakum similar to Samsun city center. M. grandiflora twigs and L. vulgare leaves can be used for biomonitoring studies due to high As concentrations in their tissues.

Heavy metals and metalloids are known as important environmental pollutants and they are toxic even at very low concentrations
It has been shown that sampling from different sides of the crown did not affect heavy metal concentrations in leaves (Bargagli, 1998)

Summary

Introduction

Due to their immutable nature, heavy metals are a group of pollutants of much concern. The presence of metallic and metalloid species in automotive fuels is undesirable and metallic or metalloid elements may derive from the raw product, such as nickel and vanadium in petroleum-based fuel or phosphorus in biodiesel, or they may be introduced during production and storage. In addition to this fuel burning, the wear of auto tires, fluid leakage degradation, and corrosion of metals are the other most important sources of pollution (Sadiq et al, 1989; Wei and Morrison, 1994; Monaci et al, 2000; Suzuki et al, 2009). Motor vehicles have direct and indirect impacts on the metabolism of roadside plants and that automobile emissions caused chronic pollution in the neighboring environment in long term (Ozakı et al, 2004; Akan et al, 2013)
