This paper reports the results of the investigation of health impacts of environmental noise context in Owerri-urban, due to incessant complains of urban dwellers of noise pollution and their effects on the health. This was measured by the use of 210 questionnaires on urban dwellers along the major routes, in which 30 questionnaires were randomly administered between sampled routes designated NP1- NP7. The observed results indicate that , automobile has 32.3%, church 3.3%, construction work 19.5%, market 5.7%, industrial activities 9.0%, hawking 10%, and school 6.6%, with automobile recording the highest response as the main source of environmental noise pollution and church having the least response. For the perceived health problems caused by environmental noise, the results further shown that Cardiovascular and Physiological effects constituted 20.5%, Hearing Impairment 25.2%, Sleeplessness 21.9%, mental health 11.4%, annoyance 6.6% and human performance 14.2%, with hearing impairment ranking the highest and the lowest being annoyance. Environmental noise was at the peak between the hours of 8- 11 am constituting 49.1%. The hours between 3-7 pm constitutes 39.5%, while <10pm has 11.4% indicating noise pollution is less in the evening time of the day where people are indoor for rest. These then calls for best management practice like enforcement of pollution law, maintenance of vehicles and creation of awareness on health implications of environmental noise.

The study was conducted at Nnewi –South of Anambra State, Nigeria to characterize soil in erosion prone area in order to know nutritional values of the soil to enable farmers employ appropriate measures to conserving the soils for high productivity. Soil auger studies were made at three locations where traverse was cut.Three profile pits designated ECH/UK/ 01 (upper slope) , ECH/UK/ 02 (middle slope ) and ECH/UK/ 03 (lower slope) were sited and samples of soils were taken to test for physico-chemical properties of the soils. The results revealed that the soils are deep, well drained , dark reddish brown to reddish brown, and yellowish red of the Munsell color notation. The soil texture in the three pedons have coarse texture that ranged from sandy clay loam to sandy loam, with high percentage of sand which is the reflection of the parent material. The bulk density ranged between between 1.50 – 1.80 g/cm3,, soil pH (3.33 – 4.09) indicating very strong acidity status, O.C.(0.28 – 0.89%), O.M (0.48- 1.54%), total N ( 0.042 – 0.98%), Available P ( 2.80 – 11.00 mg.kg-1), Na+( 0.113 – 270cmol.kg-1), K+(0.036 – 0.087 cmol.kg-1), Mg++(0.80-5.60 cmol.kg-1), Ca++(0.42 – 10.40 cmol.kg-1), EA (0.24 -1.28 cmol.kg-1) CEC( 3.104 – 16.966 cmol.kg-1), and BS ( 80.28 – 96.06%) indicating low fertility rate of the soil due to heavy leaching and intensive agricultural activities that leads to erosion of the soil to devastating stage, which could be restored by reforestation programme, integrated Nutrient Management Options, and Effective public enlightenment campaign about the advantages of soil conservation for environmental sustainability.

The study was carried out in Avu Junction in Owerri West L.G.A. at graded distant from the tarred road with an average vehicular flow between 10,000 to 12,000 per day. Soil samples were taken at the distant of 50m, 100m, 150m and 200m respectively. And auger soil samples were taken at the depths of 0-30 cm and 30-45 cm accordingly. Soil factor, heavy metals and microbial populations were investigated at graded distances. From the result of soil factors, pH values indicated acidity with decreased distant from the tarred road ranging between 4.52 – 6.32, soil temperature on the topsoil was higher than subsoil ranging between 19- 25 0C and 18 – 22 0C and soil moisture increases with increased distant from the tarred road ranging between 10.00 – 13.3. Heavy metal concentrations in the soil increased with decreased distant in the order of Pb < Zn < Ni < Cu < Cd. Overall results revealed that Cd in the soil constitutes the highest percentage of 91.7%, Ni 90.9%, Cu 90.1%, Pb. 84.7% and Zn. 81.7%. Significantly, higher fungi and bacterial populations were recorded at increased distant from the tarred road. This then called for proactive measures to checkmate soil contamination due to pollutants from vehicular flows.
