During normal activities — such as working in offices and labs, walking and bicycling around the RFS, driving to and from work — RFS occupants and visitors would not have contact with the contaminants, most of which are in the marsh, to put them at risk. If a person were exposed to sufficient amounts of heavy metals and PCBs through ingestion (eating), inhalation (breathing) or skin absorption, however, it could be harmful to his or her health.

No. Each bottler is required to test both source and finished product for substances listed in their Bottled Water Model Code. Further, products must be in compliance with applicable safety and quality standards in order to be sold in the commercial marketplace.

No, Diamondlac Waterborne Urethane is a very low odor finish because of its low VOC (Volatile Operative Chemical) count.

There are no acids in either the Sludge & Flux Remover or Siltfree products, they are both environmentally safe and can be dumped to drain in the normal way. The Powerflush Descaler contains food grade acids that can be discharged to drain. COSHH safety data sheets are available on request.

In fact some chemicals like fluoride are added to the drinking water to directly benefit the consumer. Minerals may also be beneficial and many chemicals have no adverse effects on public health.

In tests that do use ionizing radiation, the dose is usually very small, and is often similar to what you would get from natural background radiation in everyday life. As an example, a dose for a typical X-ray procedure might be 30 - 1,000 mr. Despite extensive study of the effects of radiation, direct evidence does not show that these doses are harmful to humans.

Trans fats can raise the level of low-density lipoprotein (LDL) cholesterol (also called the ??bad?? cholesterol) of our body, while at the same time lower the level of high-density lipoprotein (HDL) cholesterol (also called the ??good?? cholesterol). This increases the risk of coronary heart disease, which is the second killer in Hong Kong .

Any chemical, even salt or caffeine, in a large enough dose can be harmful. The amount of mosquito control chemicals that come out of the mosquito trucks and aircraft are not harmful to humans or pets. As with any chemical, it is always a good idea to keep exposure to a minimum. For this reason, children should not be allowed to follow the mosquito trucks as people often did in the 1940s and 1950s. Pets usually are repelled by the high pitch of the machine.

Suspended particulate matter (PM) is an air pollutant derived from the combustion of fossil fuels in the form of dust, soot, or smoke. Diesel engines account for about one quarter of the particulate air pollution from all on-road sources. More than 98 percent of the particles emitted from diesel engines are fine particles, less than 1 micron in diameter, which can bypass respiratory defense mechanisms and penetrate deep into the lungs.

Nitrogen oxides (NOx) are a family of reactive gaseous compounds that contribute to air pollution. NOx emissions are produced during the combustion of fuels at high temperatures. Nitrogen oxides can irritate the lungs, cause bronchitis and pneumonia, and lower resistance to respiratory infections. They are an important precursor to both ozone and acid rain, and may affect both terrestrial and aquatic ecosystems.(5)

Styrene is not harmful in the very small amounts most people might sometimes encounter in air or food. Someone working with resin solutions containing styrene (patching the surface of a fibreglass boat, for example) may find the odour of styrene causes slight nausea if instructions to ensure adequate ventilation are not heeded. This goes away with exposure to fresh air, and there is no lasting effect. with all chemicals it is important to control one's level of exposure to the product.

If the water is discoloured you should not assume that it is safe to drink until you have sought advice from your water company. If the discolouration is due to mains deposits, these are mostly iron and manganese as such are not likely to be harmful to your health. However you may not wish to drink the water, or give it to your family, because it looks or tastes unpleasant.

No, the limescale in kettles contains calcium and has no connection with kidney stones, which result from other materials.

No. If the manufacturer's label on a product states that glove use is required, then you must utilize proper safety protection procedures.

Federal law requires manufactures of harmful chemicals to put warning labels on their products and the requirements for safe handling. If the manufacture's labeling requires glove use then you must wear gloves. In these cases Gloves In A Bottle is not a substitute for gloves but should be used under the gloves for added protection and a second line of defense in the case of glove failure.

No. Nu-Salt® is made from 100% natural ingredients. The ingredients that are used are found naturally and are combined to reproduce the flavor of salt.

Each summer, the Idaho Department of Lands and cooperating agencies conduct a survey and detection program for gypsy moths throughout Idaho. This is accomplished by placing traps containing an attractant in trees or on fences or buildings at strategic locations. The trap contains a lure which attracts male gypsy moths to it. Once a male moth flies into the trap, it becomes stuck on a sticky material which covers the inner surface of the trap. There are no harmful chemicals in the trap.

Chemicals may have acute (short-term) and chronic (long-term) effects, which may affect various organ systems of the body depending on the chemical, dose, duration, degree and manner of exposure and susceptibility of the individual. Acute effects may include nausea, vomiting, headaches, dizziness, irritation, and loss of consciousness or even death in extreme cases.
