Likerepparttar electric mosquito zapper,repparttar 136915 mosquito magnet is one of several mosquito traps that claim to best eliminaterepparttar 136916 pesky insects. The mosquito magnet works by releasing a carbon dioxide spray, heat and moisture thatrepparttar 136917 mosquito mistakes for prey. Oncerepparttar 136918 mosquito gets too close torepparttar 136919 magnet, it is sucked in and eventually dies of dehydration. The mosquito magnet is run by a propane tank and can therefore be transported anywhere. This form of mosquito control isrepparttar 136920 most expensive of all methods and there is no conclusive scientific evidence to support its effectiveness. You can find mosquito magnets here:

Mosquito Repellent

There are a number of natural and chemical mosquito repellents that work to repel mosquitoes. The synthetic chemical repellent, DEET, isrepparttar 136921 most effective. It is essentially a poison that masksrepparttar 136922 natural odor and carbon monoxide that is released fromrepparttar 136923 human body. DEET must be used with caution, especially with children. It has been known to cause dizziness and can severely irritaterepparttar 136924 skin. For these reasons, many people choose to use a natural mosquito repellent like a citronella spray. Citronella has active ingredients that repel mosquitoes and for some,repparttar 136925 lemon smell is very appealing. You can find mosquito repellent here: Read more about mosquito repellents here:

The Cost of Inaccurate CEM Calibration Gases

Written by Leanne Merz

Continued from page 1

Ifrepparttar CEM error rate due to calibration is, between 2% and 8%, then America’s acid rain utilities could be overstating emissions by 82,050 to 328,203 tons of SO2 each year. Withrepparttar 136553 SO2 current market value at $700 per ton, this results in $57,435,000 to $229,742,100 lost potential emission credits this year – withrepparttar 136554 utility companies that use unacceptably inaccurate calibration gases, such as those produced byrepparttar 136555 43% of vendors who failedrepparttar 136556 blind audit, bearing much of that loss.

The Cost of Inaccuracy

In order to fully understandrepparttar 136557 significance of these numbers, imagine a utility company with a total SO2 Allowance Trading System (ATS) credit of 400,000 tons for one year, but which also used calibration gases that were actually 2% higher thanrepparttar 136558 tag value. That company would likely be overstating emissions by 8,000 tons (400,000 tons x 2%), which, at a value of $700/ton, means it would be losing over $5 million in allowance credits which could have been banked or sold that year. Companies using calibration gases bought from vendors who failedrepparttar 136559 blind audit, and whose gases therefore exceedrepparttar 136560 2% accuracy requirement, stand to lose even more.

Such a gross loss of potential trading credits clearly overshadowsrepparttar 136561 higher initial cost of accurate CEM calibration gases. This year’s blind audit revealsrepparttar 136562 scope ofrepparttar 136563 problem of inaccurate gases, and utility companies would do well to take notice. The companies could not seerepparttar 136564 difference because they calibrated their CEMs based onrepparttar 136565 tag values of these calibration gases. This problem is one which is only detectable after an annual or semi annual Relative Accuracy Test Audit (RATA) as mandated by EPA.
