Regulations require routine monitoring for approximately 75 chemical or radiological substances. Our water is routinely tested for over 170 substances. In addition regulations require routine monitoring for bacteria in the distribution system.

Specifically, caffeine is a problem both directly and indirectly. Acetaminophen or any drugs containing acetaminophen can be a problem. No other medicinal source of interference has been identified. Clonidine or its metabolites show up in the chromatograms but they aren't a problem. Again, listing these interferences is best left up to the individual laboratory responsible for the test being performed. If the patient is not given a list of known interferences, be sure to insist on having a copy.

The substances are lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls , and polybrominated diphenyl ethers. This includes both metals and compounds of lead, cadmium and mercury. The RoHS Directive sets maximum concentration levels allowable of these substances in the "homogenous materials" of electrical and electronic equipment covered by the legislation.

Yes, the ATA conducts random drug tests at inspections. All substances forbidden by USEF and/or CEF are also prohibited by ATA. Please check their websites for a list.

Teens may try a variety of substances, including cigarettes, alcohol, household chemicals (inhalants), prescription and nonprescription medicines, and illegal drugs. The most common illegal drug that teens use is marijuana.

The TSCA (15 U.S.C. s/s 2601 et seq.), enacted by Congress in 1976, gives the Environmental Protection Agency the ability to track industrial chemicals currently produced or imported into the United States. The EPA screens these chemicals and can require reporting, testing or banning of those that may pose an environmental or human-health hazard.

Components of those emissions include carbon dioxide, nitrogen oxides, particulates (PM), carbon monoxide and volatile organic compounds, such as formaldehyde, benzene and polycyclic aromatic hydrocarbons.

Precursors are substances that, in nature, might be inactive. However, when combined with another chemical the result is a new product. Methamphetamine starts with an inactive or marginally-inactive compound (ephedrine or pseudoephedrine) and other chemicals are added to produce the drug.

Batteries in the capsule contain sulfur dioxide, which, as with any battery, will be treated with caution in the capsule recovery.

Over-the-counter cold and allergy remedies that contain ephedrine, pseudoephedrine, propylephedrine, phenylephrine or desoxyephedrine: Nyquil, Contactd, Sudafed, Allerest 12-Hour, A.R.M.

Controlled substances such as morphine, oxycodone or lorazepam cannot be donated. These medications are typically used for pain, anxiety and sleep and cannot be returned to a pharmacy or medical facility according to federal law.

Okay, okay. Let's get technical! In Australia a poison is a substance that is listed in the Uniform Poisons Schedules. Everything else is deemed to be a "non-poison".

Animals produce various substances that can cause an allergic reaction. The main culprits are proteins in the urine, saliva, or dander (dead skin flakes). In cats, for example, the main substances that cause problems are proteins found in cat saliva which often mixes with house dust. In rodents such as mice, rats or guinea pigs, it appears that urine contains the substance that most commonly causes allergy.

Sugar water (dextrose) diluted with a local anesthetic (usually procaine). This solution has been used for more than 70 years, and has been repeatedly shown in studies to be safe and effective.

Electronic and electrical equipment must not contain more than the maximum permitted levels of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs).

There are very tiny amounts of added minerals, zinc, magnesium, silicon and copper. These are essential trace elements crucial to immune support.

Cadmium (Cd), mercury (Hg), hexavalent chromium (Cr (VI)), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) and lead (Pb).
