A literature analysis was conducted to assess the effects of tricycles and health information in the Nigerian environment, with the goal of studying their impact on human health and the environment. According to the reviewed literature, road users are constantly exposed to tricycle emissions and other environmental pollutants, which may be hazardous to health and cause climate change due to air pollution consequences, as described by a few academics. CO, N2O, SO2, CH4, H2S, PM, S2O, Pb, and VOCs were found to be above NAAQS and FMEnv, indicating that the ambient air around Nigerian towns and cities was polluted. The accumulation of pollutants in the air, on people (road users), and in the immediate environment creates major health and environmental dangers. If not carefully monitored, the occurrence of these contaminants in humans and the environment may tend to increase in the coming years, having a harmful influence on man and the ecosystem as a whole. As severe as it gets human and climatic changes have unavoidable health consequences. As a result, regular re-evaluation of tricycle emissions and their influence on human health and the environment is essential.

The study ascertains some physiochemical properties of soils around Power-line dumpsite at Boji-Boji Owa, Delta State, Nigeria. In order to evaluate the effects of municipal solid waste dumpsites on soils, soil samples were collected with the aid of a graduated soil auger at depths of 0 – 10 cm, 15 – 25 cm and 25 – 40 cm, representing top to sub and bottom soil sand also 500 m away from dumpsites which serves as control site (R). Samples were taken for laboratory analyses to determine the level of physiochemical properties such as: pH, grain size distribution, Electrical Conductivity (Ec), Organic Carbon (OC), Organic Matter (OM), Available Phosphorous (Av. P), Overall Nitrogen (ON), Basic Cations and Cation Exchange Capacity (CEC) in soils. Results obtained from the study, revealed that values between waste dumpsite and control site were significantly different. Findings showed that the pH value in sampled soils from studied dumpsites ranged from 6.22±0.06 and 7.97±0.04 while the mean pH value for controlled site was 39.8±0.08. The increase in the pH value of the sampled soil indicated an increase in CEC mean value of soil which ranged from 4.73±0.30 and 10.28±0.46 mEq/100 g while a low pH indicated low CEC mean value of 1.50±0.22 mEq/100 g. This is because there exists a positively significant relationship between pH, OC, OM, Av.P, ON, basic cations and CEC. As Ec varied between 692±4.50 to 918±4.03 μScm-1, OC varied between 0.05±0.00 to 0.64±0.03%, OM varied between 0.10±0.06 to 0.57±0.07%, Av.P varied between 8.98±0.06 to 25.36±0.22 mg/kg and ON varied between 0.44±0.01 to 0.93±0.03% across all studied dumpsites.
