Particulates Distribution Around Smallholder Gari Production Facilities in the Niger Delta, Nigeria

This study evaluated the distribution of particulates (PM1, PM 2.5, 4, 7, 10, and TSP) around smallholder gari production facilities in Niger Delta, Nigeria. The were at 3 distances (3.05, 7.62, 15.24 m) from emission source dry season (November, January, March) wet (May, July, September) Bayelsa, Rivers, Abia states. A mini-volume air sampler was used to assess concentration particulates, while health risk assessed following standard protocol using median geometric mean as reference values. ranged 11.54 – 14.99 µg/m3, 18.70 22.34 26.12 36.04 37.00 52.26 46.91 72.49 µg/m3 57.94 99.49 for PM1, PM2.5, PM4, PM7, PM10 TSP, respectively. There statistical variations (p<0.05) across months, distances, locations their interactions. correlates positively p<0.01 with higher concentrations recorded opposed season, (indication seasonal influence). assessment indicated a slight moderate pollution both seasons area, which should be taken into advisement when considering long-term exposure sensitive groups. Hence, there is need adopt sustainable management emissions due cassava tuber.
