Size and chemical composition of ambient particulates strongly influence on human health, visibility and ecosystem etc. thus it is crucial to investigate the physicochemical characteristics of atmospheric particles and also to evaluate their potential toxicity. Apart from this, Elemental composition of particulate plays an important role in the chemical characteristics of Particulate matters (PM) and provides interesting data, not only for the evaluation of its impact on human health, ecology and environment but also for the identification of specific emission sources and mass is dominates in coarse mode particulate matter in the atmosphere. Surface area may become more essential to ecological impact assessment as recognition of the oxidizing capacity, their interactions with other pollutants such as ozone and their processes [2].
