  • Waste water from industrial sites amounts to one third of total waste water discharged into To Lich river, and may have serious effects on the river water quality. With the total amount waste water of factories (Hanoi beer alcohol and beverage joint stock corporation (HABECO), Trang An JSC and Thuong Dinh industrial park) of 45,000 m3/day, these factories accounts for more than a half of total industrial waste water released into To Lich river. The analytic results of water samples taken from To Lich river show that the parameters of DO, COD, BOD5, TSS, NH4+, NO2- and coliform...

  • There are two main reasons why the chemical process industry should be motivated to reduce energy consumption and CO 2 emissions: rising concerns in companies, the public and scientifi c community about climate change or global warming, and the increasing fraction of energy in manufacturing costs. ‘ Climate change ’ [1] in this context, means a change of climate, which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods....

  • The steady increase in industrialization, urbanization and enormous population growth are leading to production of huge quantities of wastewaters that may frequently cause environmental hazards. Raw or treated waste water is very oft en discharged to freshwaters and results in changing ecological performance and biological diversity of these systems. About 70% of water supplied ends up as wastewater and several natural water reservoirs are being contaminated by untreated sewage/industrial effl uents. This makes waste water treatment and waste water reduction very important issues....

  • How are pollutants transformed after their release into the environment? How are organisms exposed, and how do physiological alterations impact population dynamics and community structure? What direct or indirect impacts occur? As early as the 50s and 60s people living near industrial plants began to recognize undesirable changes in their environment - and to ask these very questions. The discipline of environmental toxicology addresses these questions.

  • Non-point source controls washed off fields is the largest source of agricultural pollution in the United States. Farmers may utilize to reduce runoff flows and retain soil on their fields. Common techniques include contour plowing, crop mulching, crop rotation, planting perennial crops and installing riparian buffers. Nutrients nitrogen and phosphorus are typically applied to farmland as commercial fertilizer; animal manure; or spraying of municipal or industrial waste water (effluent) or sludge.

  • As the global population grows and many developing countries modernize, the importance of water supply and water treatment becomes a much greater factor in the welfare of nations. In similar fashion, the need to address both domestic and industrial wastes generated by these nations moves higher on the scale of importance. Clearly, in today’s world the competition for water resources coupled with the unfortunate commingling of wastewater discharges with freshwater supplies creates additional pressure on treatment systems....

  • The specific problems associated with concrete and concreting in hot environments have been recognised for some decades. This recognition has manifested itself over the years at a few symposia and in hundreds of papers where relevant research results and field observations were presented and discussed. In other publications the practical conclusions from these available data and experiences have been summarised in the form of guidelines for hot climate concreting.

  • Many have endeavored to make our outdoor environment cleaner and safer. The learning process that occurred showed us the limitations of our planet and also the sustainability of our ecosystem if given a chance. As a community, we learned about the water, the soil, and the air. We learned about the underground river that flowed to the surface lake. We learned about air currents that transported airstreams around our globe. We discovered the reality of plate tectonics and the ever-changing hydrogeological system.

  • Metabolism of pesticides denotes that any foreign substance that enters in the living system and how it will be changed into non-toxic and thrown out due to the enzymatic activity and other mode of action. When chemical toxins applied to nonliving substance (soil and water) that will lose the toxic principles by degradation process due to the action of biotic and abiotic factors. The time to nullify the toxicity is of prime importance and it vary depending upon the chemical molecule and environmental conditions.

  • In the United States industry is the greatest source of pollution, accounting for more than half the volume of all water pollution and for the most deadly pollutants. Some 370,000 manufacturing facilities use huge quantities of freshwater to carry away wastes of many kinds. The waste-bearing water, or effluent, is discharged into streams, lakes, or oceans, which in turn disperse the polluting substances. In its National Water Quality Inventory, reported to Congress in 1996, the U.S.
