Air Pollution Tolerance Indices of Vegetables around Abattoirs within Uyo Municipality, Niger Delta Region of Nigeria

Four common biochemical constituents of some vegetable leaves sourced from some abattoir waste – impacted soils and a Control within Uyo Metropolis in Niger Delta Region of Nigeria were assessed for their air pollution tolerance capacities using standard analytical protocols. Results indicated varied amounts of biochemical constituents in studied leaves with respect to the different abattoir soils with some constituents showing direct relationship with another. Biochemical constituents analyzed were higher in leaves from the Control soil than in the leaves from the studied abattoir soils except for relative water content. Tolerance levels of the leaves based on Thakar’s and Padmavathi’s categorizations revealed varied tolerance capacities of the tested leaves towards air pollution. Correlation analysis of the biochemical constituents of the studied leaves using Pearsons’ correlation analysis showed variable relationships.
