Abstract

Over the past few decades, heavy metal pollution has become a severe problem in many parts of the world as their concentrations are increasing at an alarming rate due to increasing unplanned industrialization and urbanization. In addition, road dust and roadside soils are threat to environmental quality as being one of the sources of the particulate matters that contain heavy metals from different sources. In order to understand the prominence, ecological and human health risks of heavy metals pollution in different compartments of the environment it has been essential to assess their concentrations, especially in road dust and roadside soil and attempted by different research groups in the world. The present review discusses briefly about road dust and roadside soil and various spectroscopic analytical techniques used for determination of heavy metals. From an environmental scope, it presents the occurrence of heavy metals like Pb, Cd, Cu, Cr, Ni, Zn, Fe and Co. This review presents significant work done on road dust and roadside soil in different cities in the world as global data and in Fiji, and their comparison as global data on assessment of heavy metals in road dust in the last few years.

摘要

在过去的几十年里，由于无计划的工业化和城市化，重金属污染以惊人的速度增加，在世界许多地方，重金属污染已经成为一个严重的问题。此外，道路扬尘和路边土壤是不同来源重金属颗粒物的来源之一，对环境质量构成威胁。为了了解环境不同区域重金属污染的突出程度、生态和人类健康风险，评估它们的浓度是必不可少的，特别是在道路灰尘和路边土壤中，世界上不同的研究小组都在尝试。本综述简要讨论了道路灰尘和路边土壤以及用于测定重金属的各种光谱分析技术。从环境的角度，介绍了铅、镉、铜、铬、镍、锌、铁和钴等重金属的存在情况。这篇综述介绍了世界上不同城市对道路灰尘和路边土壤所做的重要工作作为全球数据和斐济，并将它们作为过去几年道路灰尘中重金属评估的全球数据进行比较。
