There are currently two kinds of particles regulated by the federal and state governments. "Fine” particles (PM 2.5) are 2.5 micrometers in diameter or smaller. Larger or “coarse” particles (PM 10) are between 2.5 and 10 micrometers in diameter. Both are smaller than the width of a human hair. Leading-edge research suggests the existence of even smaller, more-damaging “ultrafine” particles.

Everyone is at risk, but children are at greater risk because they spent lots of time outdoors playing and their lungs are still developing and sensitive. People most susceptible to harm from air pollution include: Individuals with lung disease – such as asthma, emphysema or chronic obstructive pulmonary disease (COPD);

Particle pollution is usually at its worst in the winter, when stagnant, cold air traps particles close to the ground and wood burning is more popular. Unfortunately, that comforting smoky smell or haze around your neighborhood on cold winter days can be the sign of a health hazard. To help battle particle pollution, our local regulators will begin declaring “Spare the Air” days in the wintertime this year for the first time.

Unlike biodiesel, which has been extensively studied and found to have vast improvements in emmissions compared to petro-diesel, WVO has not been formally studied at all, as far as I can tell. Part of the problem is that WVO is not a consistent, repeatable fuel, so it's impossible to draw conclusions about what emissions any given restaurant may produce. I've found only one study that concerns SVO, using pure rapeseed oil, which is not what is in your typical dumpster.

The hair is individually bonded using the latest Ultra Sonic technology. Holly is one of the few in the Mid Atlantic to provide this advanced application technique.

Mushrooming of the wick caused by a carbon build up at the tip of the wick creates soot.. To prevent this from happening, do not burn a candle for more than 4 hours at a time. When the candle is cooled, turn it upside down and trim wick to a nub with scissors or clippers.

Soot is created when a flame exceeds 1 inch in length. Keep the wick trimmed to avoid such a high flame. The quality of wax will also determine how much soot a candle will produce. Scented Specialties uses only the finest premium wax blends ensuring one of the cleanest burns possible. Also, drafts cause candle flames to flicker and smoke is released when a flame is disturbed. Keep candles out of drafts. Scented Specialties recommends using some sort of "candle topper" with jar candles.

The current valuation has a presumption of correctness and it is the petitioner's burden to prove the current valuation is incorrect. Proof may include, but is not limited to: recent appraisals, affidavits of value or sale; written offers or listings for sale; contracts of building costs; topographical, FEMA floodplain, or other types of maps; photographs; contracts or leases; or any other type of written and/or verifiable proof.

Yes. Some products may fit under more than one group standard. A product can be moved between group standards, providing it meets the scope of the new group standard. Yes. Any substance which has been transferred individually, such as a dangerous good or scheduled toxic substance can be assigned to a group standard, provided that it meets the scope of the group standard.

Typically, the general rate you see is the complete charge. However, following are conditions that would require an extra charge: New York City and surrounding areas. JusRide charges and extra $100.00 to pickup/delivery bikes around NYC.

Air pollution is often a problem in patients with asthma. During times of increased pollution it is a good idea to avoid going outside, smoking and smoke-filled rooms, and any other irritants such as chemicals. Exposure to cold weather can also cause worsening of symptoms. Air filters are very helpful under those circumstances.

You can clean the glass using Dovre Glass Cleanser or any other glass cleaner. This must be done when the stove is cold. If heavy soot built-ups appear, use treble ammonia water to clean the glass. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. Don’t use any scorchers which might damage the glass surface.

The stove needs to be cleaned up at least once a year. But naturally depending on how much the stove is used. The baffle is removed from the stove and cleaned up. Note that the stove must be cold when cleaned up. Remove all residue and ash from the inside. If the baffle is fixed clean on top of the baffle with something like a vacuum cleaner. The outside surface will be kept well if vacuum cleaned with a soft nozzle.

If the temperature is too low you might experience tarry soot or creosote in your chimney. The combustion temperature will be too low if not enough air is supplied compared to the amount of wood. Tarry soot is easily recognized as a brown sticky coat. Supply more secondary air to increase the temperature. A stove pipe thermometer placed on the lower part of the flue pipe will indicate if the air supply is correct. The flue gas temperature must be approx. 250° C.

The stone is sealed with a siloxane based sealer that is invisible and prevents absorption. If you spill a liquid on the surface it beads up just as if you had poured it on the waxed hood of your car.

Launder washable garments using powdered Clean & Fresh and the hottest water suitable for the garments. Continue laundering garments until soot and/or odor are removed. You may have to launder as many as five times. Launder, using liquid household bleach (sodium hypochlorite), if safe for fabric (follow label directions); use color-safe bleach for other garments.

A well-made candle will create virtually no smoke when burning properly. However, if the wick becomes too long, or an air current disturbs the flame's teardrop shape, small amounts of unburned carbon particles (soot) will escape from the flame as a visible wisp of smoke. Any candle will soot if the flame is disturbed. To avoid this, always trim the wick to ¼ inch before every use and be sure to place candles away from drafts, vents or air currents.
