caused fracturing that led to the generation of magma from deep in the crust that helped in later filling the crater and producing the igneous complex (Faggart et. al., 1985). The igneous complex (Figure 1a) has an elongated shape (60 km long and 27 km wide) with circular deposits surrounding it similar to a bulls-eye. Evidence of the meteoric impact includes brecciation located in the center of the basin (Onaping Formation), deformation of the margin of the intrusive complex (Huronian Group), shatter
Introduction In the past century extensive research has been conducted on porous organometallic compounds for use in various material applications. Although numerous compounds containing Lewis bases, such as nitriles and bipyridines and have been reported to be successful at the sorption of small molecules, the desorption of the guest often leads to structural collapse of the host. 1,2 Metal-organic frameworks (MOFs) have shown to be a valuable class of newer materials that can support permanent
Phytoremediation: Using Plants To Combat a Stressed Environment Plants have long been adapting the traits necessary to survive in a wide variety of stressful environments – including areas of high salinity, extreme heat, drought, and freezing temperatures - but now, using genetic modification, scientists have been able to expand the role that plants play in the environment. With the advent of transgenic biotechnology, plants can be enhanced with qualities that not only allow them to flourish
to human health as well as to the Earth's ecosystems. Indoor air pollution and urban air quality are listed as two of the world's worst pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.[1] Define Air pollutants Pollutants Main
REMEDIATION AND REUSE OF CONTAMINATED LAND. A contaminated land is a land which contains substances that are actually or potentially hazardous to health or the environment. Land can also be defined as contaminated if only there is significant pollutant linkage. This means that, there must be: * an evidence of the presence of a contaminant, a pathway and a receptor that might suffer ‘’significant harm’’, * a ‘’significant possibility of significant harm’’, * Signs that pollution of control
10. Describe what is meant by the phrase “an environmentally sustainable society” as related to the human population. Distinguish between (a) natural capital (b) natural resources (c) natural services (d) solar capital (e) natural capital degradation. What is the difference between economic growth and economic development? Describe two basic ways that economic growth can be accomplished. Distinguish between developed countries and developing countries.
University – Manila fernandeze@dlsu.edu.ph ABSTRACT Among current environmental issues, pollution is of major importance in terms of the impact on people’s health and their living and working conditions regardless of the origin or source of pollutants. The indiscriminate discharge of untreated wastewater, improper disposal of solid waste and air pollution pose great risks to public health and cause significant welfare losses. The Philippine Pulp and Paper Industry though played a major role in
regulatory standards for discharging produced water. Because large volumes of produced water are being generated, many countries with oilfields are increasingly focused on efforts to find efficient and cost-effective treatment methods to remove pollutants as a way to protect their limited fresh water resources. In this research I will give information about environmental impacts caused by produced water, current produced water management practices, produced water quality characterization
Designing a Sustainable Solid Waste Collection System in Morocco Introduction Solid waste management is a matter of great concern in most urban towns in developing countries around the world. The local authorities are responsible for managing municipal solid waste but are in most cases, they are unable to discharge their duties effectively because they lack the capacity to handle the complexities of the process in terms of the design and appropriate systems. Therefore, in the design of a sustainable
