In order to assess the effect of oil milling in the environment, studies on the air quality around some local palm oil mill plants in Elele – Elele Alimini axis of Rivers State, Nigeria, have been conducted. The concentrations of various parameters which include: Respirable Particulate matter (of various sizes), Total Suspended Particulates, Carbonmonoxide, Sulphur oxides, Nitrogen oxides and the Volatile Organic Compounds (VOCs) have been measured using the Multi- RAE (PGM-50) programmable multigas monitor. The results show that the levels of the gaseous emissions were generally below detection limits. However, levels of Total Suspended Particulates were higher than permissible levels (150 – 230μm/m3), especially in the dry season and may thus be responsible for some breathing problems reported by inhabitants during the dry season.
