Urban sprawl, industrialization and extensive transportation in the urban areas have resulted the poor air quality that affects the both human health and the surrounding environment. Atmospheric nonmethane hydrocarbons (NMHCs) are major groups of air pollutants in the urban atmosphere.1 NMHCs are a group of natural and anthropogenic a...
Introduction The ornithological history of Delhi, the capital of India, is relatively old. The foremost inventory of bird species in Delhi is made by Basil-Edwardes (1926)1 who reported 204 species and sub-species. Thereafter there are many ornithologists2-7 who worked on similar lines. Apart from this, Kalpavriksh (1991)8 recorded 444 species in Delhi and its surrounding areas and Satya (1993)9 revealed 101 species remarkably affected both positively and negatively by urbanization in Delhi. ...
Introduction Historical urban areas. Having cultural values, is a part of social identity and is the identity of every country. This texture is a memorial of old people and must be preserved like a precious cultural treasure. In other words, historical centres require special attention for its value, proximity to city identity and remembrance .Features of open urban spaces, particularly central spaces such as plaza situated at the core of historic city, are directly related to rising selected...

处收集了直接太阳辐照度和总太阳辐照度的地面数据Introduction Vegetables are vital sources of minerals, vitamins, dietary fibers, antioxidants, protein and carbohydrate.1, 2 Whereas, both essential and lethal elements (metals) are present in vegetables. Heavy metals in vegetables mainly occurred due to contaminated soil and irrigation.3 Further, vegetables can easily absorb the metals accumulated on plant surfaces exposed to the tainted ambient.3 the existence of heavy metals in fertilizers enhance the probability...
Introduction Due to increasing demand for energy and rising cost of fossil fuels, solar energy is considered an attractive source of green energy that can be used to heat water in domestic and industrial sectors. Solar water heating systems generally consist of a solar radiation collector, working fluid, a storage tank, a pump, a piping unit and an auxiliary heating unit.1, 2 The most important factor in solar water heating is its efficiency. The efficiency of a solar water heating s...
Introduction Lung diseases are the pinnacle of occupational diseases. Chronic exposure to irritants at work site can lead to pulmonary disease that may persist for prolonged period, even after the exposure ceases. Occupational lung diseases (OLDs) are a broad group of pulmonary diseases developing either from repeated or persistent inhalation of particulate matters, which causes morbidity and even mortality of the workers. The prevalence of OLDs are a major health issue in the workers exposed...
Introduction Water is one of the most precious resource on earth without which there would be no life on this planet.1 Inspite of enormous volume of water on the planet, only a small portion is available for use. About 97 per cent of total water is present in oceans and seas which is saline water, and is not useful while fresh water makes up only 2.6 per cent and 4/5 of that is immobilized as ice.2 This small quantity of fresh water is responsible for sustaining al...
Introduction Ulmus wallichiana, the Himalayan Elm, is a fast growing tree species which grows in Himalayas from Kashmir to Uttarakhand between the elevations of 900 to 3000m amsl. The Himalayan Elm grows to a height of about 30m, with a broad crown having several ascending branches. The bark of the trunk is vertically furrowed and grayish brown in colour. Before the introduction of populous deltoides, it was the most cultivated tree species of the Kashmir valley having multifarious uses viz.,...
Introduction Atmospheric particulate matter represents a complex mixture of organic and inorganic substances of varying size and may enter an organism or plant in a number of ways. Roadside vegetation communities are greatly affected by the dust from highways and roads due to changes induced in biochemical parameters (ascorbic acid content, pH, Relative Water Content, total chlorophyll content).Particulate pollutants can cause many lethal effects on plants like stomatal clogging, reduced phot...
Introduction Climate change is also one of the threats among several other impacting on water resources. Scarcity of water resources, pollution and climate change will be the major emerging issues in the current and next century. Climate change and global warming is the result of a build-up of greenhouse gases (GHG), chiefly carbon dioxide, in the atmosphere. Global climate models (GCMs) are fundamental tools for predicting future climate to enable developing a better understanding of climate...

MSW is normally termed as ‘‘garbage’’ or ‘‘trash’’ is an expec...
Introduction Beginning of mining and its termination contributes towards both positive and negative effect the socio-economic status of the people living in the mining areas and its surroundings. The positive contribution noticed in the form of increasing income source, job creation/increasing employment, migration, community formation, population growth and maintenance of social activities. While the negative impacts includes labour migration, loss of cultural heritage, and risk of health ha...
Introduction In the urban atmosphere nonmethane hydrocarbons (NMHCs) are most important groups of air pollutants.1 It is an important precursor of ground level ozone (O3)2–6 and peroxy acyl nitrates (PAN) formation which can injurious to human health and vegetation.7–11 These NMHCs are emitted from both anthropogenic and natural sources in the ambient atmosphere. Thus, major anthropogenic sources are fossil fuel combustion12 automobile exhaust, ...
Introduction Release of large quantities of pollutants into the natural environment has resulted in a number of environmental problems. Heavy metals discharge is of more concern due to its toxicity and tendency of bioaccumulation.1 The anthropogenic sources of metals include industrial, petroleum contamination, sewage disposal and many a lot. Lead is the most recycled non-ferrous metal, utilized in the manufacturing, construction and chemical industries due to its malleable and du...
Introduction Previous studies on visual landscape assessment mainly involved landscape perception and preference. The visual landscape assessment queries the extent landscape meets a set of specified criteria. In landscape perception assessment, these criteria generally include aesthetic or landscape preferences.1,2 The concept of aesthetics has often been ignored by rational planners.3 Contrary to basic planning approaches, visual assessment studies attempt to integrate esthetics into planni...
Introduction In Islamic written and documents Ahar has been introduced as a developed city and the location of mystics and thinkers. Its location in the connecting path of Ardebil and Tabriz has contributed to the enhancement of the city’s significance. The religious-cultural, political, commercial issues, and the short distance from Tabriz, are among other factors contributing to Ahar’s gaining significance in the course of history. The monastery of Sheikh-Shaha...
