Samples were collected between July 2000 and June 2002 from five stations: Station 1 and 2 (upstream), Station 3 (Gelegele Port/Oil Company site) and Stations 4 and 5 (downstream). The concentrations of these parameters in the river ranged from 26.1 – 33.7oC for air temperature, 25.2 – 29.1oC (water temperature); 38.0 – 225cm (Transparency); 2.3 – 58NTU (Turbidity); 42.5 – 520.20mgl-1 (TDS); 14.66 – 210.04mgl-1 (TSS); 57.14 – 701.50mgl-1 (TS); 5.55 – 7.91 (pH); 4.40 – 11.60mgl-1 (DO); 0.80 – 5.60mgl-1 (BOD5); 10.0 – 208scm-1 (Conductivity); 17.50 – 100mg CaCo3-1 (Alkalinity); 7.02 – 34.50mgl-1 (Chloride); 0.02 – 0.43mgl-1 (Sulphate); 0.04 – 0.73mgl-1 (Nitrate); 0.28 – 3.52mgl-1 (Phosphate); 0.18 – 19.1mgl-1 (Sodium); 0.11 – 6.2mgl-1 (Potassium); 1.11 – 9.62mgl-1 (Calcium) and 0.20 – 7.78mgl-1 for magnesium. With the exception of air temperature, transparency, turbidity, suspended solid, dissolved solids, total solids, biochemical oxygen demand and nitrate which were significantly different (P 0.05) in the study stations. The impacts of the oil exploration and production operations of the Oil Company on the water quality was negligible as all parameters were relatively homogenous across the study stations, and were below the WHO guidelines for domestic usage. The environmental conditions studied have been discussed in relation to the general water quality standard.

The paper utilizes a nine-year (1995-2003) police crime record obtained from the Divisional Police Headquarters of the two local governments whose areas of jurisdiction cover the metropolis. A total of 4767 reviewed crime cases were reclassified into ten categories and examined by location within the existing urban spatial structure of high, medium and low density residential densities. All the ten categories of crime identified were encountered. However, the most prevalent were crime of acquisition (48.8%) and aggression (28.3%), with the high density area having the greatest concentration of cases. The temporal analysis shows that crime trend decreased in Ogbomoso within the period of study, a feat attributed to more gainful employment for the urban youths, particularly the increase in the use of motor cycle popularly known as “Okada” as a mode of intra-city transportation. The causal factors of crime are examined within structuralism and individualism paradigms. On planning implications, it is suggested that principles guiding landuse zoning (or allocation), infrastructural planning, and building design be reviewed so as to prevent the creation of danger zone within the urban landscape.\u0000 Global Journal of Environmental Sciences Vol. 6 (1) 2007: pp. 21-26","PeriodicalId":12569,"journal":{"name":"Global Journal of Environmental Sciences","volume":"25 1","pages":"21-26"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87059242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
