Abstract: This paper assessed the impact of black soot on public health of residents in Woji Community of Rivers State. Air quality assessment was carried out to determine heavy metal, total petroleum hydrocarbon and polyaromatic hydrocarbon concentrations in soot particles in the atmosphere of the study area. Predominant complaints/symptoms of residents as well as frequencies of diseases associated with soot inhalation before and after 2016 were inquired from health centres. Copies of questionnaire were administered to residents to determine the perceived impact of soot on their health.....

Abstract: The dynamic behavior of water composition within hydrogeological system and along drainage network coupled with uncontrolled released quantity to the environment represents a main constraint challenging the evaluation of water suitability for particular uses as well as the reuse these resources in irrigation. The efficiency of this operation and the control of the performance of this runoff are often elusive in practice. In this context, the present study aims to evaluate the opportunities for improving water management and drainage water recycle and makes advances in understanding the multivariate process controlling the long term use of the conventional and unconventional resources in southern Tunisia....

Abstract: Background: Sun and beach tourism is one of the main socioeconomic activities in the Dominican Republic. These activities take place on beaches that are part of the coastal-marine systems of the country, where a great variety of vegetation and fauna can be found. In this sense, the aim of this article is twofold: firstly, the hygienic quality of the recreational and tourist water of Playa Dorada is analyzed; and, secondly, the Quality Index of Marine and Coastal Waters (ICAM) of Playa Dorada is determined. The study focused on the mouth of the Muñoz River, which is the main body of water that flows into the beach, one of the biggest beaches for sun and beach tourism in the Dominican Republic.......

Abstract: We all know that food is the primary requirement of all living system. It is the key source of energy and also involved in growth and repair of tissue. The food that we ate are cannot directly utilized by our body, thus it will undergo some mechanical and chemical process to convert the complex material into simpler and absorbable one. Hence the body can utilize it for energy purpose. The process of conversion of food into energy molecule is known as digestion and is carried out by the digestive system.

Abstract: Climate change is an undesirable environmental happening that is causing massive alarm throughout the whole world. The Intergovernmental Panel on Climate Change (IPCC) 2002 glossary define Climate in a narrow sense as the "average weather," or more rigorously, as the statistical/demographic description in relation to mean and inconsistency of relevant quantities over a period ranging from months to thousands or millions of years. The conventional period is always three (3) decades as defined by the World Meteorological Organization (WMO). These quantities are most often drift up functions such as temperature, precipitation, and wind. Climate in a wider perspective is the condition, including arithmetical description, of the climate system.......

Abstract: Anesthetic and Haematological investigation was made on the effect of tobacco extract on Clarias gariepinus fingerlings (4.03±2.20g) using bioassay tests over a period of 96hours. Water quality parameters like Dissolved Oxygen and PH decreased significantly while alkalinity increases and temperature was almost at the same level. There were no similarities in the time of anesthesia and time of recovery at different concentrations of ethanol extract of tobacco for Clarias gariepinus. Anesthesia time decreases on increase of anesthetic dose. Fish showed marked behavioural changes like erratic swimming, aggression, jumping, air gulping, hyperventilation and settling at the bottom which indicates anesthesia time. There was increase in White Blood Cell (WBC) counts with increase in tobacco concentration, Packed Cell Volume (PCV) and Red Blood Cell (RBC) counts decreases with increase in tobacco concentration. Haematologically, there was destruction of Red Blood Cell and low concentration of Haemoglobin (HB) in the exposed fish compared to fish in the control tank.
