کتب سماویہ اور انسانی فکر کا ارتقاء ایک علمی و تحقیقی جائزہ

Allah has created human being and gave him the power of intellectual understandings. To utilize and make positive use of this Allah sent Holy books for guidance. While, keeping the sequence of these books and the historical evolution of human mind, one can easily recognize the symmetrical progress in both. Human starts living in caves and through his intelligence created homes to live, tools to gain meal, and so on, till todays growth. As far as, evolution of Holy books is considered, Scriptures were revealed in different portions as human at that stage couldn’t write or store on pages or another source. Old Testament was revealed earlier. It is combination of Torah, Psalms and other books. In the context of Islam, Torah was the first book revealed on Hazrat Mosa, in which commandments were given as per the level of Bani Israel. Afterwards, Psalms, containing poetic way inspires Bani Israel after the Torah and the Bible Last Holy book in the generation of Israel, comprises of observational and experiential way, as required in that era. Holy Quran, compiled and final version of all the past version, is summary and elemental book. In which, descriptive, observational, experiential, poetic, logical, argumentative and comprehensive technique are present. These all shows, ultimate intellectual growth of human is being address in Holy Quran. As Human is now intellectually at its peak so the teaching and techniques used are at highest level of literature, showing the step by step evolution and association of Holy books with Human being.

A Study of Polluted Eco-System of Industrial Areas Caused by the Industrial Effluents

The adverse effects of industrial pollution are becoming a challenge for scientists and environmentalists around the globe. The management of the pollution is imperative to improve the human health, economy, aquatic life and to protect from further deterioration of the environment. The leading intend of the present work was to evaluate trace elemental contaminations in agricultural soil, crops and vegetables being irrigated with industrial effluents and their treatment to reduce the pollution. This research will be beneficial to decrease the industrial pollution by the immobilization of the toxic constituents in the effluents and will provide database pertaining to the concentration of metals in the industrial effluents and their accumulation in soil, crops and vegetables. The data will assist to identify the trends, nature, and sources of pollution and will aid in the formulation of legislation related to the controlled release of industrial effluents into the environment. Moreover, present data for nutrition can be useful for nutritionists and food technologists for the formulation of diet menu for the inhabitants of the respective regions with adequacy/ safety viewpoint for balance intake of essential and toxic trace elements. For this research, more than 500 samples of vegetables (brinjal, baffle gourd, ridged gourd, tomato, pumpkin, bitter gourd, cabbage, mustard, spinach, potato, turnip, radish & carrot), crops (millet, maize, rice & wheat), effluents (ceramics, pulp/paper & textile/yarn industries) and soils (top & sub-surfaces) have been collected from the vicinity of industrial zones of Faisalabad and Gujranwala areas. Each species of vegetable and crop plants was separated into its fruits (edible portion), flowers, leaves, stems and roots to evaluate the bio-distribution of trace elements, in each portion. Neutron Activation Analysis (NAA) and Atomic Absorption Spectroscopic (AAS) techniques have been utilized to analyze the selected samples for the quantitative determination of more than 36 trace and toxic elements. Accuracy and precision have been ensured by comparing with five different certified reference materials (CRMs) and by making replicate measurements for each sample. Moreover, the Z-score method was also applied to assess the discrepancy between the measured and the certified values. Ultra-filtration membrane therapy (UFMT), which is a separation technique, was used for the reduction of toxic level in industrial effluents. Various runs have been conducted on samples of the effluents by using a lab-scale UFMT unit, which was fitted VIIwith a Polyethylene tere phthalate (PETP) membrane. This filtration technique is very effective, reliable and economical for the quantitative separation of suspended particles from the effluents. The effects of temperature and pressure on flow rates of the effluents have been investigated. The parameters such as flux, temperature, applied pressure, filtration velocity, density, concentration of the effluents and their relationships have been illustrated. Spectro-photometric analyses prove the effectiveness of UFMT system in removing dissolved coloured species and chromate ions also. The pollution parameters such as colour/ dyes, biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), turbidity, oil/ grease/ fat etc., have been reduced quantitatively up to 96% in the post filtration effluents. Moreover, in the absence of other electrolytes, the chromate removal up to 98.9% from effluents has also been achieved. Arsenic, chromium and iron metals have also been successfully removed from the industrial effluents, on laboratory scale, by using husk of sweet peanut. In this regard, optimize experimental parameters have been established for smooth/reliable performance. The analytical results for the concentrations of 36 minor, major, rare earth and toxic elements in each sample of vegetables, cereal, soil and effluents are presented in tables 6.1 to 6.12. Moreover, the evaluated concentrations of some selected trace elements have been presented in figures 7.4 ¾ 7.41 for their comparison patterns with each other. The results of physico-chemical analysis and trace elemental concentrations showed that all untreated effluents were un-fit for irrigation purposes due to the higher values of metals as compared to the NEQS values. Effluents vary in quality for textile, pulp, and ceramics industries and are specific for each industry. The effluent contamination has been decreased in the following pattern. Textile/ Yarn > Pulp/ Paper > Ceramics Faisalabad industrial area was divided into four zones (i.e. F-1, F-2, F-3 & F-4). Zone F-1 represents the area of Industrial Estate, F-2 represents the area of Ghulam Muhammad abad, F-3 represents the area of Peoples Colony and F-4 represents the area of Sitara Colony. According to the high concentration of the elements, the intensity of toxicity in the specified soils of Faisalabad is decreased in the following order. F-1 > F-2 > F-3 > F-4 VIIISimilarly, Gujranwala industrial area was divided into four zones (i.e. G-1, G-2, G-3 & G-4). Zone G-1 represents the area of Dhula, G -2 represents the area of Garjakh, G -3 represents the area of Small Industrial Estate and G-4 represents the area of Muhammad Nagar. Moreover, due to the high concentration values of concerned elements, the intensity of the toxicity in the specified soils of Gujranwala shows the following decreasing sequence. G-4 < G-3 < G-2 < G-1 Leaching tendency of some selected trace elements was observed for Faisalabad and Gujranwala soils. The elements (i.e. Ba, Cr, As, Na, Cl, K, Br & Mg) move from topsoil (S t ) to sub-soil (S s ) very easily as compared to other elements (i.e. Mn, Sb, Sc, Co, Se, Fe & Zn) due to high leaching tendency. The same behaviour was observed in both soils of Faisalabad and Gujranwala. Therefore, the quantities of the elements (i.e Ba, Cr, As, Na, Cl, K, Br & Mg) are higher in sub-soils as compared to the topsoil. This behavior was also confirmed by the evidence of observed high electrical conductivity (EC) values (5.6-4.3 mS cm -1 ) at sub-soil as compared to topsoil (4.1-3.1 mS cm -1 ) values. According to the concentrations of the trace elements, the industrial (Gujranwala & Faisalabad) and non-industrial (Rawalpindi & Islamabad) national soils are arranged in the following descending series. Gujranwala > Faisalabad > Rawalpindi > Islamabad A comparison was made among the national soils (i.e. Faisalabad & Gujranwala) and international soils (i.e. Norway & India). All soils samples were analyzed using NAA technique. According to the high concentrations of the trace elements, generally all zones are arranged in the following sequence. Gujranwala > Faisalabad > Norway > India Vegetables are staple part of food and are widely consumed in all over the world. The determination of metal contents in vegetables is significant from the viewpoint of crop-yield technology, food nutrition and health impacts. The differences for the accumulation of mineral/ metal contents in the edible portions of vegetables depend upon the soil compositions and the rate of uptake of minerals/ metals by each plant. Results showed that different vegetables had different abilities to take up heavy metals. IXHowever, the general trend shows that the maximum concentration of the trace elements is accumulated in roots while their least concentration is found in fruits i.e. edible part of the vegetables and are arranged in the following decrasing sequence. Roots > Stems > Leave > Fruits (Edible portion of vegetables/ crops) All over the world, about 70% of human diet consists of cereals and legumes. In case of edible portion of cereals the toxic activity decreases in the following sequence, which indicates that wheat crop is the least affected by the industrial effluents as compared to other cereal crops. Millet > Maize > Rice > Wheat It was observed that the concentrations of all elements are high in the wheat of Faisalabad and low in the wheat of Kashmir. The order of toxicity decreases as following: Faisalabad > Gujranwala > Islamabad > Kashmir The concentrations for majority of elements are high in the rice of Faisalabad and low in Kashmir. The order of toxicity decreases in the following sequence. Faisalabad > Islamabad > Gujranwala > Kashmir Similarly, the concentrations for majority of elements are high in the vegetables of Faisalabad and low in Islamabad. The order of toxicity decreases as under: Faisalabad > Gujranwala > Kashmir > Islamabad Regular monitoring for further assessment as to ascertain the quality of the foodstuffs and the origin of trace metal distribution is a pre-requisite. In order to obtain consolidate achievements numerous analyses of various species are required where seasonal and regional variations need to be studied in detail." xml:lang="en_US
