Term: epa


Topics from Topodia matching the term "epa"
Water Resources
waterbank , university , christina basin , water rights , environment
Water "resources" are the waters that people use or might use for human consumption, industry, etc.

Topics may include hydrology, water supply, water distribution, water quality, wastewater, flooding, surface water (rivers, streams, and lakes), groundwater, drinking water, and water treatment technology.
Air Quality
air pollution , epa , nitrogen , engine , carbon monoxide
Information, organizations, research, information and services that are concerned with improving air quality.
Ecotoxicology
pcb , research , university , stripers , ecological risk analysis
According to that quoted in http://www.bio.hw.ac.uk/edintox/enviro.htm (a cool site): Environmental toxicology and ecotoxicology are terms used to describe the scientific study of the adverse effects on living organisms that chemicals can have when released into the natural environment. There is a tendency to apply the term "environmental toxicology" only to the study of direct effects of environmental chemicals on human beings and the term "ecotoxicology" only to the study of the effects of chemicals on ecosystems and their nonhuman components.
Climate Change
climate change , greenhouse gases , global warming , climate , atmosphere
Topics include climate change (or global warming), atmospheric C02, stratospheric ozone, desertification, and change indicators.
Pollution Prevention and Recycling
pollution prevention , epa , cigarette butts , rac , materials
One definition of Pollution Prevention is: "The use of processes, practices, materials, products or energy that avoid or minimize the creation of pollutants and waste, and reduce overall risk to human health or the environment." Industrial ecology is also a closely related area. This category is primarily for resources related to waste minimization by source reduction (using fewer resources), reuse, and recycling. Composting is a technique for waste minimization, so there is a cross-link to the category Home/Gardens/Composting. Control of air and water pollution are covered in other categories of Science/Environment.
Drinking Water
drinking water , king county , reducing contamination , epa , public water systems
Indoor Air Quality
indoor air , indoor air pollution , air cleaners , particles , pollutants
This category contains sites concerning the study and assessment of factors that affect indoor air quality and sites that discuss methods of monitoring and improving the quality of indoor air.

Indoor air can contain chemical and biological pollutants such as carbon monoxide, radon, formaldehyde, asbestos, pesticides, volatile organic chemicals (VOCs), tobacco smoke, dust mites, mold, and mildew. Methods of removing these contaminants are found through research, development, and information sharing.
Acid Deposition
acid rain , acid deposition , emissions , environment , nitrogen
Acid deposition includes acid rain and other acidic precipiation, but also dry deposition of acidic compounds.
Radon
radon , lung cancer , radiation , field rw , uranium
Endocrine Disruptors
dioxins , tcdd , environment , chemicals , epa
"Endocrine disruptors" are a broad term for chemical substances that may disrupt the hormonal systems of humans and wildlife by mimicking or blocking the action of normal hormones. The best-known example is synthetic estrogens. DDT, dioxins, PCBs, and certain epoxy resins are among the chemicals that may act as endocrine system disruptors.
Engineering
selective catalytic reduction , ammonium hydroxide , risk management , water treatment , power plant

Chemical Engineering

This category is a combination of company listings and informational/resource Web sites for Chemical Engineering.

The main Engineering category page contains only listings of informational/resource web sites of interest to Engineers. Informational resources specific to a certain Engineering field are listed under that sub-category.

No companies are listed directly under Engineering, but are listed in their most appropriate subcategories of Engineering, such as Engineering:Chemical.

Before submitting your site, please review the Guidelines for Submitting a Site.

If you do not see a subcategory that you think should be included included in Business:Industries:Engineering,
please email an Editor in the Business: or Business/Industrial_Goods_and_Services section and ask them to consider including the new subcategory. (You may find a list of editors at the bottom of the category pages.)
