Abstract

Urban air pollution is rapidly becoming an environmental problem of public concern worldwide. It can influence public health and local/regional weather and climate. In the present study, airborne particulate pollutants PM10 and NOx data were collected for a period of one year (January 2014 to December 2014) at Vikash Sadan location in Gurgaon, a rapidly developing city in Haryana State in Northern India. The pollutants data were collected by the Haryana Pollution Control Board. The observed concentrations of PM10 ranged between 50.77μg/m3 to 451.0μg/m3 and of NOx ranged between 9.83μg/m3 to 216.25μg/m3. The seasonal- and annual-average concentrations of the pollutant were mostly above Indian air quality standards. These pollutants concentration were correlated with meteorological variables such as temperature, humidity and rainfall. The regression correlation analysis has been performed between particulate pollutants and meteorological parameters to investigate the relationships between them. This statistic will give an idea about which meteorological parameter play a major role in modulating the pollutants concentrations over Gurgaon.

Abstract

Plantain (Musa paradisiaca) wastes are readily available in Nigeria and if not properly managed, they constitute nuisance to the environment. They could be used, however to produce resource materials, such as activated carbon that are of public health importance. Therefore, this study assessed the use of plantain wastes in the bio-sorption of chromium from battery recycling effluent. Plantain wastes were collected from a plantation, sun-dried and ground. These were then carbonized and activated using phosphoric acid at high temperature. Samples of effluent from Ogunpa River were subjected to physico-chemical (pH, conductivity, Total Dissolved Solid (TDS) and Chromium (Cr)) analyses, using standard methods. Batch experiment studies were used in determining the adsorption isotherms of the adsorbents at varied effects of pH (2 to 12) and adsorbent doses (0.1 to 2.0g) with treatments by plantain prepared activated carbons. Data was analysed using descriptive statistics, paired t-test and ANOVA at 5% level of significance. Means of pH, conductivity, TDS and Cr+6 of the effluent sample were: 2.0 ± 0.2, 2164.7 ± 0.6 µs/cm, 895 ± 0.00 mg/l and 13.5 ± 0.0 mg/l respectively. The highest quantities (68.02%) of Cr were removed at pH 10 while the optimum adsorbent dose (2.0g) removed 68.91% of Cr. The adsorbents showed satisfactory fits of adsorption to Langmuir and Freundlich models. Adsorbents had capacity for the uptake of chromium from effluent generated from battery recycling plant with plantain peel activated carbon having the highest adsorption capacity. Conversion and treatment of effluent with plantain wastes should be encouraged in battery recycling plant, to reduce its menace in the environment and promote effective waste management.

Abstract

Advances in the development of petroleum resources has contributed enormously to the global energy demand and economic development over the past decades, however, it has left profound negative impacts on the natural environment and adverse human health effects in most oil-producing host communities around the world. Apart from the loss of petroleum-derived revenue to corruption and ineffective government's petroleum development policies, the Niger Delta region has experienced a wide range of environmental pollution, degradation, human health risks and socio-economic problems associated with petroleum exploration, development and production. Over the years, several environmental laws have been institutionalized to regulate the petroleum sector in Nigeria. The Nigerian government and other African countries have played tremendous roles in the emergence of international environmental law that regulate the establishment of environmental institutions and legislations as well as strategies for conservation and management of natural resources. However, the existing Nigeria statutory laws and regulations for environmental protection appear to be grossly inadequate and some of the multinational oil companies operating in the Niger Delta region have failed to adopt sustainable practices to prevent environmental pollution. Poor implementation of national and international environmental policies associated with petroleum exploitation and production in the Niger Delta region have resulted in huge environmental costs, degradation and issues of responsibilities from the oil companies. Therefore, this research paper examines some of the contributions of multinational oil companies operation towards environmental degradation and the role of Nigerian Government in the implementation of the petroleum-related environmental policies in the Niger Delta region.
