Odor from toaster

There is an unsual chlorine-type odor that emanates from my toaster when in use.  Could it be ozone?  It is several years old, and the problem has only surfaced in the past month or two.  The odor lingers in our house and even can be tasted by my children in their (toasted bread) sandwiches that I pack for school lunches.  Nothing else has been dropped in the toaster that might be causing the smell, and I have tried different varieties of bread.  The smell is definitely coming from the toaster, and is still somewhat noticeable when not in use.  Might this be harmful, and why have I only noticed it recently?

How to get rid of block sewer line repaired with left over oders from holes in the wall oder cleanup

Once the repairs have been made and there is no longer a supply of sewage causing the odor, the best way to remove all odors is to place a commercial ozone machine in the room and seal it off for several days. It will completely eradicate all odors by removing all of the oxygen from the room. I use one of these machines to remove odors from travel trailers.

Before I start up my topic I will like to explain what the word refrigerant means and other things that I fill you have to know more on the subject matter.
What are refrigerants? Refrigerants are fluids that absorb heat at low temperatures and rejects heat at higher temperatures. The principles of refrigerant allow for heat pumps and straight air conditioners to function properly; because of their pressure temperature relationship. This relationship allows for heat transfer.
In the HVAC industry refrigerants are given a trade name known as "R" names. Examples of these names are R22, R134a, and R502. These names help to describe the different types of refrigerants. Refrigerants have various chemical make ups, along with different properties. Some refrigerants are only able to work in high pressures while others use low pressures to function properly.
There are three main make ups of refrigerants that are currently used. Hydrogenated Fluorocarbon Refrigerants (HFCs), which is made up of hydrogen, fluorine, and carbon. Because they do not use a chlorine atom (which is used in most refrigerants) they are known to be one of the least damaging to our ozone. Hydrogenated Chlorofluorocarbon Refrigerants (HCFCs), which are made up of hydrogen, chlorine, fluorine, and carbon. These refrigerants contain minimal amounts of chlorine; they are not as detrimental to the environment as some other refrigerants. Chlorofluorocarbon Refrigerants (CFCs), which contain chlorine, fluorine and carbon. These refrigerants carry high amounts of chlorine so they are known for being the most hazardous to the ozone layer.
Sometimes refrigerants consist of a two or more chemical compounds. These blends break down into two types: Zoetrope’s and Azeotropes. Zeotrope A zeotrope is a liquid mixture that obeys Raoult's law. It shows no maximum or minimum when vapour pressure is plotted against the composition at a constant temperature.Zeotrope refrigerant mixes are mainly made of three different types of refrigerants. The characteristic that describes this type of refrigerant is that all three refrigerants keep their own properties; they act as 3 individual refrigerants. Azeotropes are mainly a blend of two refrigerants. The property that defines this type of refrigerant is it acts as a single refrigerant. This effect the boiling points of both types of refrigerants.
The most important fundamentals of refrigerants before expanding into how they work. This key principle is that refrigerants do not make things 'cold' they remove heat. This principle is preached in the HVAC industry. It is a common misunderstanding of homeowners and technicians.
A pressure temperature relationship is a way of describing the specific temperature that relates directly with the pressure of a substance. This allows control of refrigerants boiling temperatures. Controlling a refrigerants boiling temperature allows for proper heat transfer.
Heat transfer is when heat from one place is transferred to another place, this is also referred to as a refrigerant cycle. Generally we control heat transfer through air, water and refrigerants.
This type of heat transfer happens through conduction. Conduction is when heated molecules, with lots of movement, collide with slow moving molecules. The warmer molecules, fast moving, always move towards the cooler ones, or the slow moving molecules.
Refrigerants are sold in disposable container that includes a check valve. This limits the reuse of old refrigerants and prevents mixing refrigerants. Refrigerants are identified by a standard color code. The labels also contain information on which type of refrigerant is in the container along with any safety hazards there are.
There are several safety hazards when handling refrigerants. In order to help prevent damage to the ozone, technicians are required by law to become EPA certified. There are four (4) main types of certification; Type I, Type II, Type III, and UNIVERSAL. Type I includes small appliances such as refrigerators. Type II includes high pressure appliance with the exclusion of small appliances such as split-systems. Type III includes low pressure systems such as chillers. A Universal certification includes all three types of certifications. For more information on refrigerants, their properties, how they effect the environment, and becoming certified.

How do I read the graduations on the purifier control & what do the 1 or 2 red plate settings tell me?

The graduations are incremental for your ozone output for the purifier control. Generally, the machine can put out enough ozone to cover 3000 sq ft. (when the control is moved all the way to the right, about 5 o'clock.) Half way should be about 1500 sq ft or 12 o'clock. For general air cleansing, you should set the purifier control to produce enough ozone so you smell it when walking into the room (after home) for about 30 seconds. The ozone smell should disappear after that. If it lingers, you've got it set too high. For more severe odor control you can set it higher but remember that some of us are more sensitive to the odor no matter what the setting. It may need some adjustment based on your individual preferences.

I'm confused about the 'red plates' as you mentioned. The original machine comes w/ 2 ozone plates (made of glass) and doesn't produce ozone when one of the plates is removed. I'm guessing that the lines may tell you when you're engaging both plates to work, i.e. more ozone being produced & blown into the room or less only calling on one plate to produce ozone. If you send me a close up pic of the control panel I may be able to tell you more.

1.why do u think ecology is important? 2.think of some environmental issues their causes and solutions......

Why Ecology is important ?
Ans : Ecology is of utmost importance to all species including us. We, like all other animals depend on this earth for everything; food, water, shelter. Everything on this earth depends on something else but ecology is so dynamic that even the smallest perturbation can upset everything.
A good example is global warming. Many people think that 2 degrees over a decades is a small amount of time. NOTHING in Ecology is small, the repercussions are severe. Plants need a certain temperature to thrive, warming of the earth can upset this and also upset life and mating cycles. We depend on those animals to eat and certain animals also survive on those animals.
In addition, human interference with the ecology of certain places can also exacerbate the problem of natural disasters. When we log on mountainsides and hills, we destabilize soils and the topology of the landscape. Heavy rains which would originally cause some kind of erosion would now cause landslides that could engulf roads and cause hazards to villages or towns and people that live in those areas.
In addition, chapparal forests in California is a type of terrestrial biome. If we do not understand the fact that these trees will constantly be subjected to fires, then people will build luxurious houses in these areas (which they are already doing), and when wildfires rage through the area, they will want insurance and money to rebuild. The fact is, houses are not supposed to be built in those areas in the first place, and if they are, insurance companies should not be shelling out money to the rich and misinformed who choose to live in such a biome.
So you see, Ecology is important to us financially, aesthetically, and also for our simple survival on this planet. Hence, it should be taken with utmost importance not only for us but for our next generation.
Some environmental issues are :
1. Land degradation
Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting upon the land.[1] It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.[2] Natural hazards are excluded as a cause, however human activities can indirectly affect phenomena such as floods and bushfires.
Land degradation is a global problem, largely related to agricultural use. The major causes include:
-Land clearance, such as clearcutting and deforestation
-Agricultural depletion of soil nutrients through poor farming practices
-Livestock including overgrazing
-Inappropriate Irrigation [4] and overdrafting
-Urban sprawl and commercial development
-Land pollution including industrial waste
-Vehicle off-roading
-Quarrying of stone, sand, ore and minerals
e main outcome of land degradation is a substantial reduction in the productivity of the land.[5] The major stresses on vulnerable land include:
Accelerated soil erosion by wind and water
-Soil acidification and the formation of acid sulfate soil resulting in barren soil
-Soil alkalinisation owing to irrigation with water containing sodium bicarbonate leading to poor soil structure and reduced crop yields
-Soil salination in irrigated land requiring soil salinity control to reclaim the land [6]
-Soil waterlogging in irrigated land which calls for some form of subsurface land drainage to remediate the negative effects [6]
-Destruction of soil structure including loss of organic matter

2. Ozone depletion
Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4% per decade in the total volume of ozone in Earth's stratosphere (the ozone layer) since the late 1970s, and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole. In addition to this well-known stratospheric ozone depletion, there are also tropospheric ozone depletion events, which occur near the surface in polar regions during spring.

The detailed mechanism by which the polar ozone holes form is different from that for the mid-latitude thinning, but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and bromine.[1] The main source of these halogen atoms in the stratosphere is photodissociation of chlorofluorocarbon (CFC) compounds, commonly called freons, and of bromofluorocarbon compounds known as halons. These compounds are transported into the stratosphere after being emitted at the surface.[2] Both ozone depletion mechanisms strengthened as emissions of CFCs and halons increased.
CFCs and other contributory substances are commonly referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (270-315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol that bans the production of CFCs and halons as well as related ozone depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in skin cancer, cataracts,[3] damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.
The ozone hole and its causes
The Antarctic ozone hole is an area of the Antarctic stratosphere in which the recent ozone levels have dropped to as low as 33% of their pre-1975 values. The ozone hole occurs during the Antarctic spring, from September to early December, as strong westerly winds start to circulate around the continent and create an atmospheric container. Within this polar vortex, over 50% of the lower stratospheric ozone is destroyed during the Antarctic spring.[14]
As explained above, the primary cause of ozone depletion is the presence of chlorine-containing source gases (primarily CFCs and related halocarbons). In the presence of UV light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction. The Cl-catalyzed ozone depletion can take place in the gas phase, but it is dramatically enhanced in the presence of polar stratospheric clouds (PSCs).[15]
These polar stratospheric clouds(PSC) form during winter, in the extreme cold. Polar winters are dark, consisting of 3 months without solar radiation (sunlight). The lack of sunlight contributes to a decrease in temperature and the polar vortex traps and chills air. Temperatures hover around or below -80 °C. These low temperatures form cloud particles. There are three types of PSC clouds; nitric acid trihydrate clouds, slowly cooling water-ice clouds, and rapid cooling water-ice(nacerous) clouds; that provide surfaces for chemical reactions that lead to ozone destruction.[16]
The photochemical processes involved are complex but well understood. The key observation is that, ordinarily, most of the chlorine in the stratosphere resides in stable "reservoir" compounds, primarily hydrochloric acid (HCl) and chlorine nitrate (ClONO2). During the Antarctic winter and spring, however, reactions on the surface of the polar stratospheric cloud particles convert these "reservoir" compounds into reactive free radicals (Cl and ClO). The clouds can also remove NO2 from the atmosphere by converting it to nitric acid, which prevents the newly formed ClO from being converted back into ClONO2.
The role of sunlight in ozone depletion is the reason why the Antarctic ozone depletion is greatest during spring. During winter, even though PSCs are at their most abundant, there is no light over the pole to drive the chemical reactions. During the spring, however, the sun comes out, providing energy to drive photochemical reactions, and melt the polar stratospheric clouds, releasing the trapped compounds. Warming temperatures near the end of spring break up the vortex around mid-December. As warm, ozone-rich air flows in from lower latitudes, the PSCs are destroyed, the ozone depletion process shuts down, and the ozone hole closes.[17]
Most of the ozone that is destroyed is in the lower stratosphere, in contrast to the much smaller ozone depletion through homogeneous gas phase reactions, which occurs primarily in the upper stratosphere.[18]

I was considering Biozone for restrooms etc and I assumed,as your info.says that it would be odour free?Some I have seen are not odour free.Is it just a uv lamp system or is there some form of ozone...

the UV lamp does produce some ozone .. this one specifies .04 ppm .. thats not very much but might be detectable as a slight fresh air odor .. some other types use electrostatic filtering and some even have strong ozone generators .. ozone does kill bacteria, fungus and such and will freshen the air removing many odors but is not considered healthy in large or concentrated amounts or for prolonged periods .. the UV lamp will also kill bacteria and fungus without producing so much ozone.

Purifying Method: Photoplasma, UV, ions, and ozone.

Norcold 982 will not get cold.

If the there is a strong ammonia odor and no cooling, then you probably have a leak in the system somewhere. These types of absorption units must be repaired in a specialty shop. The most common place for a leak is the condenser coil, but can also be the evaporator inside the unit, if the odor seems to emanate from that area.

XL-15 Classic Living Air emmitting Foul Odor!!

Ionizers do cause a bad odor to happen. I work in the copier business and do work around machines that can cause an ozone to happen when there are ran. Copiers like ionizers can cause an ozone to happen because the air particles are being electrically charged. The smell isn't good to be breathing in as well.

Here is an EPA report about ionizers

The Consumer Products Safety Commission is going to be making a decision about the health effects on ionizers by the end of the year. Their decision can effect selling ionizers all together.

This industry should have been regulated years ago and after what happened to Sharper Image this year due to their arrogance it isn't doing the industry any favors. They went out of business because of Consumer Reports findings and tried to sue them for it.

If you really want the air in your house cleaned, the best way to do it is using a hepa filter.
