Abstract

Natural resources play a fundamental role in the economy of country and create the situation to achieve the goals of sustainable society, these valuable resources have to be conserved  and used with care. Destroying the forests and rangelands will lead to a dark future full of poverty, starvation and environmental pollution. Forests and rangelands play a considerable role in reducing air pollution, minimizing soil erosion, protect against destructive floods, creating a pleasant place of recreation and relaxation while also allowing recharge of underground water resources. In short, ensure the preservation of resources essential for life on the earth.  This is Part 3 of a comprehensive review of the impact of dust particles and aerosols. Part 1 (Squires, 2016a) examined the mechanisms by which dust particles and aerosols become airborne and the effect of particle size on deposition patterns. Part 2 (Squires, 2016b) focussed on the impact of particulates on the physiology, and productivity of plants. In this paper, attention is directed to the impact on human health of dust and aerosols generated from dust storms and from industrial sites (mines, factories and from roadside dust generated by passing vehicles). Effects of such dust range from nuisance (that arises from loss of visibility) to increased costs of clean-up of premises, through to serious health problems generated by inhalation of dust particles and aerosols.
