The understanding of environmental contamination is gradually improved as better investigation and research are achieved. Previous study on single contaminants was no longer adequate in coping with the increasing occurrences of complex environmental co-contaminations
which have been addressed more and more. Heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants in the environment
whose co-contaminations are frequently detected in the environment and their interactions have often made the remediation problematic. Soil and groundwater
the major bio-habitats
are the venues where such co-contaminations of HMs and PAHs occur. The co-contaminations of soil and groundwater will seriously threaten human and other ecological health. This paper hence reviews the source
distribution
migration
transformation and eco-toxicity of the co-contaminations of HMs and PAHs. It also briefly summarizes the interactions between contaminants and potential remediation technologies of the co-contaminations. The perspective research directions of such co-contaminations are proposed based upon the literature review.
