Rain samples were collected from Warri and Port Harcourt, two major oil-producing cities of Nigeria in April-June, July-August, and September-October 2005 and 2006. Awka, a “non-oil” city was used as control. Samples were collected from three points, using clean plastic basins fastened to a table, 2 m above ground level and 115 m away from tall buildings and trees. Water samples were filtered and acidity determined using digital pHmeter. The results show that the rain samples were acidic. The pH values for the 2 years under study show that the rainfall in Warri was more acidic than that of Port Harcourt. Oil exploration and other anthropogenic sources may be responsible for the acid rain in the Niger Delta region of Nigeria.

The study of visibility in the Niger Delta region is necessary because it reflects the atmospheric changes caused by economic expansion in Nigeria. Cities in the Niger Delta (especially Port Harcourt) are the most polluted cities in the country and therefore visibility degradation has become one of the major environmental challenge in Nigeria. Analysis of a 31 years (1981-2012) monthly mean horizontal visibility data and monthly mean datasets of meteorological parameters such as relative humidity and wind direction obtained from Nigerian Meteorological Agency (NIMET) and the National Centre for Environmental Prediction (NCEP) for Calabar, Uyo, Port Harcourt, Owerri, Warri and Akure was done using statistical techniques. A correlation analysis was done and the annual visibility variability indexes from (NIMET) shows significant correlation with the (NCEP) datasets for R/humidity at r=0.1334 and Wind direction at r=0.1210 respectively at 90% confidence level from t-test. This study concluded that the relationship of the atmospheric visibility and meteorological factors are closely related. The results showed that visibility is more correlated with Relative humidity in places with high hydrocarbon activities leading to excess aerosol loading like Port Harcourt while it is better correlated with wind direction in places with less hydrocarbon activities like Calabar and Akure. The results of this study can assist policy makers and operators in establishing positive strategies to improve the air quality.

Aim: This study is to determine the prevalence, causes, types and patterns of hearing impairment seen in a tertiary hospital in the Niger delta region. Study Design: A hospital based descriptive study of all patients with complaints of hearing impairment seen at the ear nose and throat clinic of the university of Port Harcourt teaching hospital within the period of January 2015 to December 2019. Results: Bilateral affectation was commoner among those that have hearing impairment n = 366(65.2%) 91.2% while n = 54(8.8%) was found to have normal hearing. Majority of the ears had profound degree of hearing loss n= 313 (25.4%) with the highest number of it found in the right ear 27.0% however, there is no statistical significance between the side of the ear affected and the degree of hearing loss. Conclusion: The young adults are the most affected; age 30-39 years with bilateral affectation and profound degree of hearing loss. Infective conditions such as CSOM are still very predominant in the aetiology of hearing loss in our environment.

Introduction: Sickle cell anaemia (SCA) is a lifelong multisystem disease endemic in sub Saharan Africa. As the population of patients living with SCA into adulthood continues to increase, pulmonary hypertension has emerged as one of the foremost complications with severe implications on the quality of life and a risk factor for premature mortality. Aims: The present investigation is a prevalence study in the Niger Delta region regarding pulmonary hypertension in adults with sickle cell anaemia. Methods: One hundred and six adults were recruite; fifty-three sickle cell anaemia patients recruited from the outpatient clinic of the haematology department of the University of Port Harcourt teaching hospital, Port Harcourt and 53 genotype AA adults recruited as control. Transthoracic echocardiography was performed on all 106 subjects. The prevalence of pulmonary hypertension was assessed based on tricuspid regurgitation jet of velocity ≥2.5 m/s (estimated SPAP≥30 mmHg).  Results: The mean age of the SCA patients was 25.94±6.47 years, (range 18-45 years) while the age group with the highest representation was those within 18–27 years. The proportion of males (52.8%) was slightly higher than that of the females. Pulmonary hypertension was observed in 5.7% while high normal pulmonary artery pressure was observed in 1.9% of the SCA patients studied. Conclusion: The prevalence of pulmonary hypertension in adults living with Sickle Cell Anaemia in this study is 5.7% and it is significantly influenced by the age of the study cohort and the method used in assessing this parameter.

This study investigated the nitrate, sulfate, total dissolved solid (TDS), electrical conductivity, total hardness (TH), and bicarbonates of rainwater samples collected from Warri and Port Harcourt between April–June, July–August, and September–October of 2005 and 2006 to depict onset of rainy season, mid-rainy season, and end of rainy season for the two major crude oil–producing cities of the Niger Delta region of Nigeria (although Port Harcourt is also noted for non-oil manufacturing industries). The same was done in Awka, a non-oil producing city in the hinterland of southeastern Nigeria. In each of the cities, rain samples were collected from three points in a triangular equilibrium using a clean plastic basin fastened to a table 2 m above ground level and 115 m away from tall buildings and trees. The parameters were determined after filtering, using their respective standard methods. Averages of 1.50, 1.81, 1.13 and 2.14, 1.50, 1.86 mg/l of nitrate for April–June, July–August, and September–October were recorded for Warri in 2005 and 2006, respectively. While 15.21, 3.23, 22.31 and 20.89, 9.96, and 14.27 mg/l were recorded in Port Harcourt. Sulfate levels for Warri and Port Harcourt for the same periods are follows: 1.38, 1.88, 1.06, 1.50, 1.43, 1.50 and 2.64, 1.15, 5.88, 4.73, 1.90, 1.55 mg/l, respectively. Nitrate levels were higher than sulfate. Other parameters include TDS (5.44, 4.79, 3.30 and 7.63, 3.69, 2.56 mg/l for Warri in 2005 and 2006; 12.57, 2.07, 25.214 and 28.87, 6.73, 7.80 mg/l for Port Harcourt for the same periods). Other parameters also varied in that order for the 2 years in same cities. Crude oil exploration and gas flaring in the Niger Delta, and multiplicity of cottage industries in Awka, impacted on the inorganic ion pollution of the rainwater. This may have public health implications in the region.
