AN ASSESSMENT OF THE AIR QUALITY STATUS OF PARTICULATE MATTER IN TWO INDUSTRIAL SITES

This study is focused on assessing the air quality status of particulate matter pollution in two industrial nuclei (Niger Mills Flour Industry and UNICEM/LAFARGE cement industries) Calabar Cross River State, Nigeria. The imperative for derives from recognition that matter(PM ) as one six criteria pollutants has a significant human ecological implication our environment. Pm been implicated many deleterious effects health. objectives include: (i)determination volumetric concentration ambient air, (ii) understanding nature constituents, (iii) isolation constituents other , (iv) ascertaining permissible levels comparison areas. literature explored such thematic areas environmental impact pollutants, standards indices. methodology involved employment specialized instruments sampling recording selected stations mapped out by Global positioning system GPS) sites. field were conducted seasons dry seas (Feb 2018) wet season (May. obtained results presented tables(Tables 1-4). These table further summarized compared with Federal Ministry Environment (FME) (Table5-8). findings reveal location not exceedingly above limits. Secondly, at higher than UNICEM/LAFARG industry are. Thirdly, large more homogenous flour mills area central area. Finally health assessment threatened short run.
