Water and sediment samples from Cross River, Imo River, and Qua Iboe River Estuaries were collected and treated using standard analytical procedures. The samples were analyzed for their physicochemical properties, total hydrocarbon content (THC), and trace metals. Results obtained revealed that, the mean levels of total suspended solids (TSS), total dissolved solids (TDS), turbidity, colour, biochemical oxygen demand (BOD), THC, cadmium (Cd), iron (Fe), nickel (Ni), lead (Pb), and zinc (Zn) in water were higher than their acceptable limits in Nigeria. Whereas, the mean levels water pH, electrical conductivity (EC), dissolved oxygen (DO), nitrate, sulphate, phosphate, and copper (Cu) were within their acceptable limits. The results obtained also revealed that, the mean levels of nitrate, THC, and Fe in sediments were higher than their recommended limits. While the levels of pH, EC, sulphate, phosphate, Cd, Cu, Ni, Pb, and Zn in sediments were within their recommended limits. This study indicated that the anthropogenic activities by oil and oil-related companies within the Niger Delta Region of Nigeria may have contributed significantly to the high level of toxic substances in the water channels within the zone. The results obtained revealed that, the direct or indirect exposure to untreated water from the studied water channels may result in serious health challenges. Hence, the environment should be closely monitored to forestall a devastating situation in the region.

The study aimed at investigating the climate of the Niger Delta Region (NDR) of Nigeria. This is to ascertain the variations in rainfall and temperature in the Niger Delta Region. The study utilized the ex-post facto research design. The study utilized the annual rainfall and temperature time series data from 1925 – 2018 periods. That was generated from the archive of the Climate Research Unit (CRU) Ts 4.03 using Google earth. The grided points of 5ox5o high resolution of thirty-two (32) CRU Ts 4.03 stations were utilized for the study. In order to analyse the data on rainfall and temperature the descriptive statistical techniques were employed. While testing the formulated hypotheses, the one-way analysis of variance (ANOVA) was utilized to decide the significant difference in stations, additionally the Turkey Test was utilized to decide were the difference in the mean lies, while the Mann-Kendell Trend Test was used to determine the upward and downward trends in rainfall and temperature. Thus, the study revealed that the mean distribution of rainfall and temperature in the Niger Delta region for the past ninety-four (94) years showed a downward and upward trend with a mean of 2238.3mm and 26.7oC in rainfall and temperature respectively. While, the highest and lowest rainfall (2600.7mm and 1854mm), was recorded in 1955 and 1984 which indicates an increase of 746.7mm. The highest and lowest temperature (27.4oC and 25.9oC) was recorded in 2017, 1976 and 1977 respectively which indicate a rise of 1.5oC. Furthermore, the study revealed that there is a statistically significant variation in rainfall in the Niger

Objectives: The study is aimed at assessing the profile of unnatural death in an oil-rich city in Niger Delta region. Method: This is a descriptive retrospective study of all homicidal, accidental and suicidal deaths examined forensically at theCentral hospital mortuary, Warri from January 2003 to December 2016. Results: Unatural death accounted for 802( 82.5% ) of all medicolegal cases examined within the study period. Homicidal, accidental and suicidal deaths accounted for 541(67.5%),(247) 29.7% and 14(1.1%)respectively of the unnatural deaths. A total of 713(88.9%) males and  89(11.1%)  females were encountered , giving a male-female ratio(MFR)of  8:1. The mean age of the victims is 32.7 years with the peak occurring in the 3rd decade.The most commonly used  weapon for homicidal death is firearms, accounting for 374(69.1%)  of cases. Accidental death result mainly from RTA, drowning, burns and electrocution whichrespectivelyaccounted  for 142(57.5%) 34(13.8%)26(10.5%)  and 19(7.7%) of the cases; and with a MFR of 6:1. 14 cases of suicides were encountered during the study involving 11 males and 3 females,  giving a MFR of 7:2. Conclusion: The causes of unnatural death are mainly preventable.The resultant premature death, affecting mainly males of productive age is a great source of concern. There is need for the government, the community and individuals to contribute their quotas in reversing this ugly trend.
