Environmental Testings

Environment includes our surrounding. Surrounding means the air, water, soil, and plants and animal life. Human and animals are depends on environment. That’s why any changes in environment effect our life very much. So, we do our environmental testing to protect our world and life.
 
Effects Of Environmental Changes
There are many bad effects to our world of environmental changes. But the main and worst effect is to our Human and Wildlife Health. Infectious disease is the leading cause of human death worldwide. Gone is the euphoric perspective of the mid-1970's that significant infectious diseases affecting humans in developed Nations were essentially problems of the past. The reemergence of infectious disease has continued to gain momentum since the mid-1980's. Disease events affecting natural resources have paralleled the eruption of infectious disease in human populations. Both situations are reasons for concern and have a common causative bond of ecological change.
Ecosystem Health is an Environmental Barometer for Human Health. The occurrence of significant forms of disease among wildlife can be an indication of deteriorating ecosystem health. Disease emergence is an early warning of challenges to the integrity of the biological systems that comprise ecosystem sustainability and provide for economic growth and healthy human populations.
 
Another bad effect is Pathogenic Microorganisms in Public Water Supplies. Source waters for drinking-water supplies are coming under increased scrutiny. The largest waterborne disease outbreak in U.S. history occurred in Milwaukee in 1993. In that outbreak, 403,000 people became ill and 104 died of Cryptosporodiosis, a disease caused by the protozoan Cryptosporidium. However, problems with the sanitary quality of U.S. water supplies and source waters were well known even before the Milwaukee outbreak. Various estimates suggest that between 900,000 and 2 million people become ill each year in the United States by ingesting protozoan, bacterial, and viral pathogens in incompletely treated and untreated drinking water.
 
Health Impacts of Domestic Coal Combustion in China is also an example of bad effect of environmental changes. Domestic Coal Combustion is the primary source of energy for hundreds of millions of people worldwide. In many developing countries such as China, unventilated stoves are commonly used. Emissions from the unventilated coal fires are known to cause a variety of health problems that affect tens of millions of people in China alone.
 
Greenhouse gases including water vapour, carbon dioxide and methane, are naturally present in the atmosphere. They are the world's insulation, absorbing long wave infra-red radiation emitted by the earth's surface. Without Greenhouse gases (GHGs) the world would be about 33°C colder, so in this sense GHGs are life-supporting. The issue is not their presence but the concentrations at which they occur. As concentrations increase, the earth’s surface temperature may rise, leading to global warming. 
The likely effects of global warming include a greater frequency of extreme weather conditions: droughts; heat waves; and floods caused by rising sea levels.
Carbon dioxide concentrations have risen from an estimated 280 parts per million (ppm) before the industrial revolution, to 380 ppm today. During the last century, the earth’s surface temperature rose by about 0.6°C. The Intergovernmental Panel on Climate Change (IPCC) estimates that it could rise by between 1.4 and 5.8°C by the end of this century.
 
Parameters Of Environmental Testing
Our Nation's environment -- the air, water, soil, and plant and animal life -- is constantly changing as natural processes and human actions affect it. So these are the parameters of Environmental Testing. By testing these parameters we could know that how much our environment is changed.
 
Environmental Testing Activities
Environmental testing activities in the environment theme area include studies of natural physical, chemical, and biological processes, and of the results of human actions, the goal is to provide the understanding and scientific information needed to recognize and mitigate adverse impacts and to sustain the environment. Activities include data collection, long-term assessments, ecosystem analysis, predictive modeling, and process research on the occurrence, distribution, transport, and fate of contaminants as well as the impacts of contaminants on biota.
The tests have to do in Environmental Testing are_

1-     High and Low Temperature
2-     Humidity
3-     Altitude
4-     Salt Spray
5-     Thermal shock
6-     Burn-in
7-     Sand and Dust
8-     Rain
9-     Wind
10-  Water
11-  Fungus
12-  Explosive atmosphere
13-  Thermal Vaccum
14-  Highly Accelerated Life Test (HALT)
15-  Highly Accelerated Stress Screening (HASS)
16- Accelerated Stress Test (AST)
17-  Environmental Stress Screening (ESS)

In Environmental Testing we have to test the humidity of weather and the heavy rain. The percentage(%) of gases in the air. Air quality test means fungus, bacteria, radon, carbon monoxide, carbon dioxide, and allergen test in air. We test our water in Environmental Test for most common contaminants. In Environmental Test Testing our water couldn't be simpler. In Environmental Testing we do Watersafe Drinking Water Test. This test we do to test lead, bacteria, pesticides and more in dinking water. Accelerated Stress Test, Accelerated Stress Screening Test example like HALT, HASS, AST, ESS Test include in Environmental Testing.
 
Equipments Of Environmetal Testing
There are many services and equipments are available for Environmental Testing. Many research and survey are does for Environmental Test. Many companies sell many different kind of equipment for different purpose of Environmental Testing. We will get different brand of equipment for Environmental Testing. Example- Columbia Weather Systems, Inc. provides professional weather monitoring equipment for public safety and industries affected by weather conditions. That equipment measures the meteorological parameters of wind speed, wind direction, barometric pressure, humidity, temperature, rainfall, solar radiation, fuel moisture, and leaf wetness. Wind Tunnel machine can be set up in a modular layout to provide wind speeds over 100 miles per hour in a test section up to 36" in diameter, as well as wind driven rain and dust exposure. Environ's AST system employs the latest in aggressive temperature change rate and repetitive shock technology. The system is capable of running a variety of stress testing techniques, including HALT, HASS, STEP STRESSING, and many more.
 
What Our Government and Other Organization Do For Environmental Testing
In 2005, climate change was at the top of the global policy agenda. The Kyoto Treaty came into force, committing the 156 participating countries to making emissions reductions and the EU Emissions Trading Scheme became operational. However, Kyoto was only designed as a first step – and policy makers are now discussing what new agreement might follow it in 2012 and how all the significant countries can be involved.
The issue was discussed by the G8 group of world leaders at their July summit and at the United Nations Climate Change meeting in Montreal in December. The year also saw increasing scientific consensus on the potential risks of climate change, exemplified by a report issued by the Scientific Academies of the G8 countries, along with those of Brazil, China and India. The report concluded that global warming is occurring and added that most of the warming in recent decades is likely to have been caused by human activity.
