Environmental Impact Assessment and Source Identification of Total Suspended Particulate Matter and Some Elements Emitted from a Workplaces in Jordan


Authored by Omar Ali Al Khashman



The objective of the present study was to assess the extent and severity of atmospheric particulate concentrations and metal concentration in dust, street dust and soil in the Aqaba Industrial Estate (AIE). Samples of dust, street dust and soil were analyzed for their contents of atmospheric particulate matter and elements (Fe, Cu, Ni, Pb, Zn, Mn and Cr) after digestion with nitric acid. This study shows that analyzed major sources and magnitude of elements pollution. The mean concentrations of the elements were as follows: CFe > CPb > CZn > CCr > CMn > CCu and CCd where C stands for concentration. Zn, Cd and Pb were in high levels in the area close to the workplace, while the chromium level was low. This study indicates that all of the elements are concentrated on the surface soil, and decreased in the lower part of the soil, this due to reflect their mobility and physical properties of soil and its alkaline pH values. The results indicated that the mean concentrations of elements in the dust, street dust and soil were too low to yield any known environmental health effects. The use of factor analysis is determined three groups of elements that differ in their distribution. The first of these components is polluted soil, which occurs distributed inside the study area. The second is the unpolluted soil, which occurs mostly in the study. The third factor represents the physicochemical sources of the variability, and this factor is not significant.

Growth Response of Heterobranchus Longifilis Fingerlings Fed Diets Supplemented with Moringa Oleifera Leaf Meal as Replacement of Soybean Meal Authored by Ibiyo Lenient MO Aquaculture is the fastest growing sector of the world‘s animal production with an annual increase of about 10% [1]. To sustain such high rates of increase in production, a matching increase in fish feed production is imperative. Because fish meal is a limited primary source and plants are widely available and reasonably priced, the use of plant protein sources in aqua feeds should be considered [2]. Therefore, in order to attain more economically sustainable, environmentally friendly and viable production, research interest has been directed towards the evaluation and use of non-conventional sources of plant and animal protein. Soybean meal is one of the most nutritious of all plant protein sources because of its high protein content, high digestibility, and relatively well-balanced ami no acid profile [3]. Owing t...
