Water pollution and human health.

Abstract: This study was conducted at Department of Zoology, University of Gujrat, Pakistan during 2016- 2017 as a term paper for Master of Philosophy. The data regarding water pollution and human health was obtained and compiled through a thorough review of various published research articles of international reputed journal and relevant books. Water covers about 70% Earth’s surface. Safe drinking water is a basic need for all humans. The WHO reports that 80% diseases are waterborne. Industrialization, discharge of domestic waste, radioactive waste, population growth, excessive use of pesticides, fertilizers and leakage from water tanks are major sources of water pollution. These wastes have negative effects on human health. Different chemicals have different affects depending on their locations and kinds. Bacterial, viral and parasitic diseases like typhoid, cholera, encephalitis, poliomyelitis, hepatitis, skin infection and gastrointestinal are spreading through polluted water. It is recommended to examine the water quality on regular basis to avoid its destructive effects on human health. Domestic and agriculture waste should not be disposed of without treating.

Factors Affecting Water Pollution: A Review

Abstract: This study was conducted at University of Gujrat during 2016 to 2017 as a term paper for Master of Philosophy. The data regarding effect of ozone depletion on human was reviewed and compiled as a review paper from various published articles of international reputed journals annual/environmental reports of recognized organization and ebooks. Factors which are effecting water pollution are addressed. Water pollution is very important problem of 21st century. Due to water pollution pure water is becoming less scare day by day. The biggest cause of water pollution is industrialization and increase in population. By drinking polluted water people becoming more and more ill.

Role of housefly (Musca domestica, Diptera; Muscidae) as a disease vector; a review

Abstract: Housefly, Musca domestica, has a long history of association with animals, which still are suffering from its harmful impacts. It occupies human and livestock premises and acts as a source of nuisance and annoyance to them. The present bibliographical study explains role of House fly as a disease vector of humans and livestock. This article highlights various aspects of the life of the said pest that includes its general description-morphology, biology, life cycle, its pest status and major control strategies. The pest is cosmopolitan in nature and shows holometabolous metamorphosis as it passes through all stages of development like egg, larva, pupa and adult which takes 10 to 14 days for its completion. Its life span is between 15 to 30 days. With respect to control strategies of the said pest, it was reviewed that chemical control is the most common and efficient technique but dependence on insecticide for fly control isrndecreasing due to increased insecticide resistance and environmental constraints. Biological control with natural enemies also provides reasonable results for outdoor control. Indoors control is mainly dependent on light and odor baited traps. Therefore combinations of several methods for the control of House fly population like Integrated Pest Management (IPM) program is recommended for the effective and efficient results.

Pesticide Exposure and Human Health: A Review

Abstract: This study was conducted at Department of Zoology, University of Gujrat, Pakistan during 2014-2015. The data for the last two decades regarding pesticide exposure and human health was compiled through a thorough review of thirty three research articles published in various journals of international repute. The way of pesticide exposure and their health outcomes, including the neurological, fetal growth, birth and cancerous outcome. Several pesticides are effect as neurotoxins and cause neuronal disorder and degenerative diseases, some effect fetal growth and cause congenital anomalies and other are carcinogenic for human. The data analysis of international researcher revealed that due to extensive use of pesticide increase their exposure to human which result greatly increase the risk of cancer, neural and birth defects.

DNA Extraction from Insects by Using Different Techniques: A Review

Abstract: This review paper was prepared at Department of Zoology, University of Gujrat, Pakistan during 2014-2015. The data for the two decades, DNA Extraction from Insects by Using Different Techniques was compiled through a thorough review of many research articles published in various journals of international repute. Insects are very important economically and ecologically for human due to their various roles, as pests, decomposer in nutrition cycle, vector for the transmission of certain diseases and a source of medically and economically important products. To identify insect, and for research on their role, different molecular techniques are used. For each molecular technique, high quality DNA is required, which is extracted from the insects by different techniques. The selection of DNA extraction technique is depended upon specimen under study, time required for extraction, economical stander of technique due to reagents and equipment used for extraction and most importantly extracted DNA quality. In this paper, most frequently used techniques for DNA extraction from insect with different size and condition are outlined. This paper is only a guide for these techniques and we describe them briefly.

A study on the effects of promising edible and non-edible biodiesel feedstocks on engine performance and emissions production: A comparative evaluation

Abstract: Global energy demand is increasing due to the population growth and industrialization. In order to fulfill the energy demand with considering global concern, it is necessary to find out alternative fuel sources. Biodiesel is one of the best choices because of its immense potential to be part of energy mix in the near future as well as the capability of reducing greenhouse gas emissions. This paper aims to provide information to the engineers, industrialists and researchers who are interested on biodiesel. The paper presents a comprehensive review on the impact of potential biodiesel feedstocks (edible and non-edible) on engine performance and exhaust emissions including details of engine and operating condition. A large number of literatures from highly rated journals in scientific indexes are reviewed including the most recent publications. Most of the authors showed that using biodiesel from various feedstocks in diesel engines slightly lowered brake power and brake thermal efficiency but increases BSFC than diesel fuel. It was also reported that biodiesel significantly reduced the PM, HC, CO and CO 2 emissions but gives slightly higher NOx emissions. It was shown that NOx can be reduced by some approaches such as blending with additives and EGR technique. The study concluded that biodiesel can be used in compression ignition engine with no or minor engine modification. Finally biodiesel can be used as a substitute of diesel fuel to fulfill the energy demand, reduce dependency on fossil fuel as well as the exhaust emissions of the engine.

Role of biofuel and their binary (diesel–biodiesel) and ternary (ethanol–biodiesel–diesel) blends on internal combustion engines emission reduction

Abstract: Exhaust emission from transportation sector affects the human health. It is the main contributor to degrade the air quality. Biofuel is promising alternative to maintain both human health and environment quality better by reducing harmful emission from biofuel runs diesel engines. This study explores the global and Australian greenhouse gas (GHG) emission scenario along with the contribution of transportation sector to the GHG emission in Australia. Besides, the world biofuel standard with the target and mandate taken by the government of different countries to use biofuel are also discussed in the paper. This review indicated that engine emission is dependant on some factors such as engine operating condition, biofuel types, blending etc. Both biodiesel–diesel and ethanol–biodiesel–diesel blending plays a significant role in reducing the exhaust gas emission such as carbon monoxides (CO), hydrocarbons (HC), particulate matter (PM). But ethanol–biodiesel–diesel and biodiesel–diesel blends produce higher carbon dioxides emission, which is absorbed by the crops and considered as lower net CO2 emission. Finally, about 5–10% of ethanol with 20–25% biodiesel can be added with petro-diesel effectively and efficiently to reduce global GHG emission, thus to maintain environment and human health better.
