Abstract :

A study was conducted at Port Harcourt, in the humid tropical rainforest zone of Nigeria, to determine the
concentrations of pollutant gasses in livestock buildings in order to establish baselines for exposure limits in the context of animal and human welfare in tropical environments. The concentrations of aerial ammonia, nitrous oxide, methane, carbon monoxide, hydrogen sulphide and sulphur dioxide in selected intensively managed poultry pens in Port Harcourt area of Rivers State, Nigeria were measured during the month of November, 2007. Studies reveal that overall mean aerial concentrations of carbon monoxide CO (19.1±1.35 ppm) was the highest mean value recorded and was followed by the 1.06 ± 0.16 ppm and 0.89±0.14 ppm recorded for flammable gas (methane) and ammonia respectively, while the
0.12±0.07 ppm recorded for nitrous oxide was lowest. The study showed that these figures are lower than limits recommended for animals in Europe. [Chidi Nwagwu, Promise N. Ede, Ifeanyi C.
