Introduction At present lead pollution is considered a worldwide problem because this metal is commonly detected in several industrial wastewaters.1 Undoubtedly, industrial waste based adsorbents offer a great promise for commercial purposes. Solid wastes are a vexing societal problem mandating attention to recycling. Recycled product quality is not always high or recycle may not be feasible. However, conversion of solid wastes into effective low-cost adsorbents for wastewater treatm...

Introduction Surface water resources are distributed among 15 basins. The largest source of external surface water is the Yarmouk River at the Syrian border. Originally, the annual flow of the Yarmouk River was estimated at about 400 million cubic meter (MCM) (of which about 100 MCM are withdrawn by Israel). Total flow is now much lower than 400 MCM as a result of the upstream Syrian development works, which took place in the 1980’s. The Yarmouk River accounts for 40 % of the surfac...

Introduction Surface water is usually rain water that collects in surface water bodies, like oceans, lakes, or streams. Surface water can become contaminated in many ways, one of which is direct recharge can come from industries sources. A change in the water chemistry due to surface water contamination can negatively affect all levels of an ecosystem. It can impact the health of lower food chain organism and consequently the contaminated surface water can also affect the health of animals an...

Introduction Certainly dust deteriorates the ecological condition and can be defined as the fluctuation in any atmospheric constituent from the value that would have existed without human activity (Tripathi and Gautam, 2007). Environmental degradation exerts significant pressure on human health; unfortunately these aspects are closely associated with the hazards to the environment and human caused by transport specially road transport (Dora and Phillips, 2000). The impact of dust pollution on...

Introduction Two aspects of global climate change that directly influence plant physiology, growth and productivity; increasing in concentrations of ambient ozone (O3) and carbon dioxide (CO2).1,2 Atmospheric CO2 is projected to continue rising to at least 550 ppb by 2050.3 The current annual average (O3) is predicted to continue increasing by 0.5–2% per year over the next century, mainly due to increases in precursor emissions from anthropogenic sources.4,5 Gre...

Introduction Narmada is originated from eastern Madhya Pradesh at Amarkantak (Situated at 20° 40', 80° 45' E), flows towards west and finally joins Arabian sea at Broach (Situated at 21°43', 72° 57' E).Dams, built to change natural flow regimes, are one of the most significant human interventions in the hydrological cycle. The construction of dam’s results in physical, chemical and biological changes to natural ecosyste...

Introduction Mahalgaon is a village in Kamptee Taluka, Nagpur district of Maharashtra state, India1  Nag River is the main river which flows through the city and passes through Mahalgaon village hence it is the easiest and cheapest source of water for irrigation to the villagers on the bank of this river. The river serves as the drainage for the city and is highly polluted by urban waste and heavy metals2 Most of the village formers are engaged in vegetable cultivation and the vi...

Introduction Heavy metals are important environmental pollutants, particularly in areas with high anthropogenic pressure. Their presence in the plants, atmosphere, soil and water, even in traces, can cause serious problems to all organisms. The presence of heavy metals in sewage sludge, used as agricultural fertilizer is a major problem for crop and environmental qualities and their impact on human health, because most of the heavy metals are persistent due to their immobile nature (Devkota e...

Introduction Global warming is the increase in the usual temperature of Earth's atmosphere and oceans since the late 19th century. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980. Warming of the climate structure is unambiguous, and scientists are certain that it is primarily caused by i...

Introduction The Gaza Strip is located in the Middle East bounded by the Mediterranean Sea to the West, Egypt to the South and Israel to the North and West, and has a total area of 365 km2. It is 45 km in length and 5 to 7 km in width in the north to a maximum of 12 km in width in the South as, as shown in Figure 1.1 The Gaza Strip’s population was about 1.65 million in 2010 with a population density of about 4,520 capita per square kilometer, which is the highest population density...

Introduction It is also an important area for Urial and Sind Ibex.15 In the Khirthar Protected area Complex (KPAC), total of 33 species of mammals has so far been recorded15 Asia is rich in habitats and biodiversity, and correspondingly rich in turtle species.12 According to IUCN (2009), there are now 1,677 reptiles species have been included on the IUCN Red List, with 293 added in 2009. In total, 469 are threatened with extinction and 22 are already Extinct or Extinct in the wild. Pakista...

Introduction The gravest environmental challenge that Jordan faces today is the scarcity of water. Indeed, water is the decisive factor in the population/resources equation. Whereas water resources in Jordan have fluctuated around a stationary average, the country’s population has continued to rise. A high rate of natural population growth, combined with periodic massive influxes of refugees, has transformed a comfortable balance between population and water in the first half of thi...

Introduction Mexican glaciers of the Iztaccihuatl, Orizaba’s peak (Citlaltepetl) and Popocatepetl will disappear in the next 10 to 35 years, warns a study from the National Autonomous University of Mexico (UNAM) (Lorenzo 1964). Mexico’s Glaciers focalize an unusual global interest, on one hand; they are the only one in latitude 19° north and exist due to the mountains that allocate then have heights higher than 5000 meters. International organization studying gl...

Introduction   Atrazine (2-chloro-4-ethylamino-6-isopropylamino-striazine), is probably the most commonly used chlorinated herbicide in the world.1 Atrazine is a selective systemic and most popular herbicide introduced in 1958 by J.R. Geigy. It has a range of trade names including Marksman, Coyote, Atrazina, Atrazol and Vectal. Atrazine is used for the pre and post-emergence control of annual and broad leaved weeds and perennial grasses; it inhibits photosynthesis and interferes with...

Introduction Water is fundamental human need; human life and existence of all eco system depends largely on the availability of water both in high quality and sustainable quantity supply, safe water is the water delivered to the consumers that can be used directly for drinking, cooking, and washing. It is the responsibility of authority at all levels to review, inspect, monitor and evaluate on continues basis the water supplied to the community, using constantly updated water standard John (1...

Introduction Most pharmaceuticals are persistent in wastewater especially the effluent from pharmaceutical industries and also from hospital wastes. Considerable attention has been already devoted for the removal of these pharmaceuticals from wastewater. Ibuprofen (IBP) and paracetamol (PCM) are two important pharmaceutical drugs which are regularly used to cure from fever, migraine, and diseases resulted from inflammatory disorder.1-4 Figure 1 shows the chemical structure of IBP and...
