Noting that the noise levels lie much above the prescribed limits there is an imminent health risk \u0000to the exposed population. The complexity and magnitude of the problem of noise pollution call for effective \u0000and well-planned measures in the country, Nigeria.

Transportation of crude oil, gas and processed petroleum products takes place in pipes, most often steel pipes. Several methods have been used to combat the problem of buried pipeline corrosion among which is cathodic protection. Cathodic protection of a buried steel pipe using zinc anode and a 12 volt DC power source has been studied. The experiment was set up in the laboratory for 35days using moist soil sample from Niger Delta region of Nigeria and weight loss recorded every seven days. Results show that after twenty one days, the protected steel began to lose a very small amount of weight, compared to weight losses for unprotected steel and the anode. A total of 0.04g of the cathodically protected steel was lost after 35days compared to a loss of 0.43g for the unprotected steel. The experiment shows that 90.69% protection was achieved with cathodic protection method of corrosion control. The work demonstrates that buried steel pipes in Niger Delta region of Nigeria can be cathodically protected against failure with very small quantity of electricity. It is recommended that this study be carried out in a soil with high salinity, typical of the Atlantic Ocean shore of Niger Delta where several oil pipelines are laid.","PeriodicalId":72927,"journal":{"name":"Environment research journal","volume":"6 1","pages":"304-307"},"PeriodicalIF":0.0,"publicationDate":"2012-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70027738","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}

This was done primarily by measuring the Dissolved Oxygen (DO) downstream of a pre-selected pollution discharge point on River Atuwara and then predicting the same using the modified Streeter-Phelps equations. Other data gathered from each of the 17 sampling stations on River Atuwara and used in the analysis included Biochemical Oxygen Demand, (BOD), pH, stream velocity, stream depth and distance. Predicted DO deficit trend lines were first fitted by retaining the original re-aeration coefficient component, k 2 , of the modified Streeter-Phelps equation (USGS equation) and subsequently by substituting it with Atuwara reaeration coefficient model. It was found that the latter displayed better predictive capacity. Results also demonstrated that the auto-purification capacity of the river which is already limited by the relatively low DO saturation level is further threatened by the wastes being discharged into it at varying intervals. Some of the wastes which are non-biodegradable and acidic were also found to be interrupting the auto-purification processes of the river. Water from River Atuwara requires treatment before it can be considered safe for consumption by its current users.","PeriodicalId":72927,"journal":{"name":"Environment research journal","volume":"6 1","pages":"151-157"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70027289","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}

As criteria of water quality vary with purpose of use of the ground water, selection of water quality parameters, involved in working out quality index for specific use, also differs. Use of Ground Water Quality Index (GWQI) technique to assess irrigation water quality is innovative in this study. Electrical conductivity (EC), sodium adsorption ratio (SAR), and residual sodium carbonate (RSC), judged as the three most important parameters to determine irrigation quality of ground water, have been used to work out GWQI in this study. Preparation of iso index maps using water quality scores, derived through GWQI tool, vividly portray the irrigation water quality status of the study area where most of the area fall under excellent and good categories. The marked difference in water quality with respect to season in some areas of southeastern and southwestern parts of the study area may be correlatable to the recharge and discharge zones of ground water respectively.","PeriodicalId":72927,"journal":{"name":"Environment research journal","volume":"6 1","pages":"197-205"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70027682","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}
