What You Need To Know About Mercury in Fish and Shellfish

Filed under: Uncategorized - 03 Sep 2012  | Spread the word !

Fish and shellfish are an important part of a healthy diet, since they contain high quality protein and other essential nutrients, are low in saturated fats, and contain omega-3 fatty acids. A well-balanced diet that includes a variety of fish and shellfish can contribute to heart health and the proper growth and development of children. Women and young children in particular should include fish or shellfish in their diets due to the many nutritional benefits.


Nevertheless, fish and shellfish may contain traces of mercury. For most people, the risk from mercury by eating fish and shellfish is not a health concern. Some fish and shellfish contain higher levels of mercury that may harm an unborn baby or young child’s developing nervous system. The risks from mercury in fish and shellfish depend on the amount of fish ingested, and the levels of mercury in the fish and shellfish. Therefore, the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) are advising women who may become pregnant, pregnant women, nursing mothers, and young children to avoid some types of fish, and eat fish and shellfish that are lower in mercury.



If you follow these recommendations for young children, pregnant women and women of child-bearing age:

  • Do not eat shark, swordfish, king mackerel, or tilefish because they might contain high levels of mercury.
  • Eat up to 12 ounces a week of a variety of fish and shellfish that are lower in mercury. Five of the most commonly eaten fish and shellfish that are low in mercury are the following: shrimp, canned light tuna, salmon, Pollock and catfish.
  • Check local advisories about the safety of fish caught by family and friends in your local lakes, rivers, and coastal areas.

It is always important to follow food safety guideline, and that is certainly true with the mercury content of fish. If you are fishing, get a copy of the state guidelines for fish consumption for the area in which you are angling. It is very important to realise that some areas are more heavily polluted by mercury and methylmercury than others. Using up to date food safety guidelines, you can largely avoid the harmful mercury content of fish.

Liquid mercury is the only liquid metal at standard temperature and room conditions and many assume that it cannot be dangerous for their health. However, it can lead to severe poisoning which has both short and long term effects on people’s health. This is why it would be best for mercury to be kept contained. Handling mercury does not pose any risk if it is encapsulated and enclosed, so make sure that all the possible mercury sources in your homes are enclosed and do not have any leakages. If you break a container by accident and the mercury falls out, you should know some practical tips on how to handle it. You need to keep calm, since mercury will most likely break up into many small droplets and roll away into many areas.

The first thing you need to do is make sure that all people and pets are removed from the area. Pets and children are likely to be lured to the balls formed, so you do not want them to inhale the mercury, nor to distract you from cleaning up. You should also remove any jewelry and then put on a pair of gloves that will help you retrieve the mercury droplets without them coming in contact with your skin. Then, you should try to recover as much as possible by using a stiff piece of paper or an eye dropper in order to scoop up the droplets. You can also use a paper towel or wet wipe. The remaining droplets can be picked up with a sticky tape. After “collecting” them, it is important to place the droplets together with the cleaning items you have used in a sealable plastic bag.

You should then double bag it, label it so that no one touches it, and dispose it properly by calling local authorities to find out where toxic waste is being disposed in your area. Placing it in the usual garbage bag is not a good idea. It is very important to remember never to use a vacuum cleaner or broom to clean liquid mercury when it spills. Also, if the mercury containers breaks and the metal falls on the carpet, you should cut out the piece of carpet and dispose it in a double plastic bag, as well. It is better to get a new carpet than to jeopardize your health and the health of the ones living with you.

Liquid Mercury In Many Products

The liquid mercury is found in many products and devices. This substance is also used in manufacturing a lot of things. Nonetheless, even though the liquid mercury is useful from several points of view, it has been banned in some countries. Liquid mercury can cause toxicity, skin allergies, headaches and many other problems. In combination with other elements, liquid mercury can cause severe health problems, so a medical consult is a must. The liquid mercury is used in the thermometers and many other measure devices, but if they break, the risk of toxicity is very high. The liquid mercury has a low melting temperature, which makes it easier to be used for manufacturing many products. The liquid mercury is used for obtaining many other chemicals such as caustic soda, but also in medicine.

The thermometers also use liquid mercury. It’s true that they display the right results, being of a superior quality than the digital ones. This is useful, but in case they break, the liquid mercury will boil away, entering in the respiratory system and from there, into blood flow, causing problems. In some countries, the liquid mercury thermometers are banned, so people are safe. Unfortunately, this chemical is found also in cosmetics, mainly in mascara and lipsticks. Although the effects will not be obvious from the very beginning, after a longer period of using these products very often, the body can be intoxicated.

Under these circumstances, women who use cosmetics have to pay a lot of attention to the ingredients of the products. This is the best way through which they will avoid unpleasant symptoms and health problems. Many women have experienced awkward symptoms, without knowing the cause. The medical tests were right. Only more detailed tests have showed that they had an increased amount of liquid mercury in their blood or in a certain organ. Reading carefully the ingredients or buying only safe products, appreciated for the lack of chemical substances is the best protection against unpleasant experiences.

Liquid Mercury is Dangerous to Human Health

Most people know of liquid mercury from the old-fashioned thermometers. However, it is also one of the most dangerous elements with serious repercussions on the human organism. If ingested or inhaled, liquid mercury can lead to slow death. There are legitimate and safe uses for liquid mercury, though many industries such as mining and paper production are moving away from mercury processes.

Many people are not aware of the extreme danger liquid mercury when it is no longer contained in a thermometer or air-tight container. All liquid mercury spills should be treated seriously and quickly, since it slowly evaporates when exposed to the air. The air in the room can reach contamination levels just from just a few drops of liquid mercury in a broken thermometer.

When liquid mercury is spilled, it forms droplets, similar to paint not dissolving. These droplets can accumulate in the tiniest of spaces and then emit dangerous vapours. Depending on the quantity of liquid mercury that has entered the body and the period of exposure, symptoms of liquid mercury poisoning can include impairment of the peripheral vision, disturbances in sensations usually in the hands, feet and sometimes around the mouth, lack of coordination, muscle weakness, mental disturbances as well as mood swings.

People who come in contact with too much liquid mercury can also experience pain or imbalances of the heart, the kidneys, the lungs and the immune system. As you can see, liquid mercury poisoning has many negative effects. However, there are some tips on how to avoid and what to do in case of liquid mercury poisoning. If the thermometer has broken, try to clean up the liquid mercury beads by using one sheet of paper to carefully roll them onto a second sheet of paper. Place the mercury in a plastic bag and then in a zip lock container. Do no use chemicals on the places where liquid mercury has spilled, because there can be violent reactions. Always check the thermometers to see if there any mercury leakages.

Liquid Mercury Dangers

The liquid mercury is known for its huge toxicity. To prevent this from happening, many objects containing liquid mercury have been banned. Liquid mercury toxicity symptoms consist of disturbed sensation, problems with hearing, vision, coordination, pain, itching, burning sensations, skin discoloration, swelling. These symptoms caused by liquid mercury depend on the period of time during someone has been exposed to, as well as on the amount of mercury. The liquid mercury is found in numerous devices from thermometers, light bulbs, to sphygmomanometers, float valves and electrical switches, but if one of these objects falls down, the person who is around them, will be intoxicated.

Although today there are digital thermometers, those containing liquid mercury are the most reliable and give precise results. Users have to pay a lot of attention and make sure it will not fall and break. In the past, liquid mercury was used for poisoning and even today, are many cases when people  have been killed by being poisoned with this substance. The liquid mercury is used also found in dental amalgams, batteries, pesticides, but are we safe? Moreover, it has been discovered that even make-up products contain liquid mercury, which is very dangerous. Unfortunately, even the most expensive and long lasting lipsticks, contain this substance.

A high price does not always mean safety, so the best thing is to inform more about the products containing liquid mercury. It is the surest way to protect ourselves and the people we care about. Health problems may emerge being caused by this substance, but it is very difficult to find the answer in time. The chemical has been banned in many countries, such as being used in thermometers and other objects. It is very good that such protection measure have been taken, but liquid mercury is still used in manufacturing lots of products. Companies and the government should take care of this problem and inform population about what is going on and which substances are being used. Being precocious and informed are always the best things that we could do to prevent difficult health problems from happening.

Liquid Mercury Poisoning

Mercury is the only chemical element in Mendeleev’s periodic table of elements which is liquid at standard conditions for temperature and pressure. This is why it is also called liquid mercury. While researchers have always been intrigued with this fascinating heavy metal, little did they know that liquid mercury can cause severe poisoning. Also known as mercurialism or hydrargyria, liquid mercury poisoning develops when a person has been exposed to mercury or one of its compounds, that is if the doses are high. Toxic effects of liquid mercury include brain, lungs, and kidney damage, as well as the development of diseases such as acrodynia, Minamata disease, and Hunter-Russell syndrome.

The symptoms of liquid mercury poisoning are very obvious. They include vision, hearing, and speech impairment and disturbed sensation, as well as a lack of coordination. Peripheral neuropathy is also considered a symptom of liquid mercury poisoning, when presenting as paresthesia or itching, together with burning or pain sensations. Skin discoloration, the shedding of the skin and swelling may also occur due to liquid mercury poisoning. The degree of the symptoms will naturally vary according to the liquid mercury dose, and to the duration and method of exposure. Information on these matters will be necessary in order for the doctor to properly diagnose the condition. After being diagnosed with liquid mercury poisoning, identifying and eliminating the source of exposure is very important, because otherwise, the decontamination process will be in vane.

Mild liquid mercury poisoning can be easily treated. The patient will need to remove his clothes, wash his skin with water and soap, and then flush his eyes with saline solution, if or as needed. If the patient shows signs of severe liquid mercury poisoning, chelation therapy is to be given immediately. Although many liquid mercury poisoning effects are reversible, prolonged exposure can cause irreversible damage, especially to children and infants. This is why you must proof your house against liquid mercury. Make sure you inspect the products which are likely to contain liquid mercury, such as thermometers, fluorescent light bulbs, thermostats, air conditioners, and other electrical switches. Checking your food sources of methylmercury is also a good idea.

Liquid Mercury Uses

Mercury is an important chemical element, being also known as “quick silver” or “hydrargyrum”. It is the only metal that is liquid, but at standard conditions and temperature. Liquid mercury is used in thermometers, barometers, float valves, as well as manometers and sphygmomanometers. Liquid mercury can also be found in electrical switches and apparatus that are used for scientific purposes. This metal  is toxic, so it is a controversial topic if it is alright to use it or should be substituted with something else.

Subsequently, liquid mercury has been replaced with alcohol, galistan, as well as other materials, but it still is included in many products. Unfortunately, many accidents happened when thermometers filed with liquid mercury have fallen, broke and people were intoxicated, developing severe health problems. Liquid mercury is also used in lightning as it helps short-wave ultraviolet light to transform in visible light.

This white-silver metal can melt amalgams made from gold, zinc, iron and many others. Usually, liquid mercury is used mainly for manufacturing industrial chemicals, as well as electrical and electronic applications. Liquid mercury can also be found in thermometers that are able to measure high temperature and fluorescent lamps. It has been also introduced in medicine and used in dental amalgams, but also in vaccines, antiseptics and many other products. It has been said that liquid mercury in vaccines can cause autism in children, but there was no evident proof.

Nonetheless, liquid mercury is a very toxic metal. It is also used in cosmetic products, which can lead in time, to severe health problems that affect women. The most common product containing liquid mercury is mascara, as well as skin care products. Those people who eat seafood or fish may also have higher amounts of liquid mercury in their body. It is very important to know all liquid mercury derivative substances and read carefully the docket. We will know which products to avoid and which are safe to buy and to use. Nonetheless, technology should substitute this metal completely to make sure that no accident will happen.

Liquid Mercury History

Filed under: Uncategorized - 07 Mar 2012  | Spread the word !

Liquid mercury was first discovered years ago. Throughout this period of time, liquid mercury was used with different purposes, new findings on the use of mercury actually managing to revolutionize many domains. Liquid mercury is believed to have been first discovered in the 15th century B.C., the metal actually being used in the artifacts of Egyptian tombs. Romans considered liquid mercury to be a poisonous substance, as it was found that the exposure to the metal caused the death of numerous mine workers. Anyway, this belief has only been linked to liquid mercury, not generally to the metal in other physical states. In fact, the name of the chemical element comes from a Roman god, Mercury.

Well, the Romans were not actually wrong when they claimed that liquid mercury can cause health problems. In fact, today, specialists consider that liquid mercury can cause severe kidney and nerves damage. And that is not all. It seems that liquid mercury can also cause birth defects and blindness, damaging at the same time the environment. Although the discovery of mercury dates back to more than 3500 years ago, the chemical element in not actually found free in nature. The metal becomes liquid at room temperature. Liquid mercury was only identified as a human toxin in 1866. In 1956, the chemical element was widely recognized as being poisoning and not only for humans, but actually for every living organisms.

The metal is however able to allow electrical current to pass through it, which makes it important in various fields. A very curious fact you should know about liquid mercury is that it is commonly used in numerous domains in our time. So, the metal can be used in medicine, for the manufacturing process of thermometers and barometers, but also for batteries and dental amalgams. The chemical element can also be used in vapor lamps and chemical pesticides. Liquid mercury is a chemical element, which becomes liquid at room temperature. However, mercury is a metal, having the atomic number 80. Still, due to the toxic effects of the metal, the use of mercury has been limited or actually banned in numerous parts of the world.

How Liquid Mercury Is Used In Medicine

Liquid mercury is, contrary to what most people think, a metal. The liquid mercury has the Hg symbol and the atomic number 80. Liquid mercury is also popularly known as quicksilver and hydrargyrum. Liquid mercury is actually the only metal that in standard conditions of temperature stays in its liquid state. It has the boiling at 357.73 degrees Celsius and the freezing point at -38.83 degrees Celsius – measured with international standards. Liquid mercury poisoning is very dangerous for people. This does not mean that the metal is not useful for producing certain objects, necessary for everyone. The liquid mercury is used to produce thermometers and many other things. It is mostly used in research, lightning and medicine.

Liquid mercury compounds are extremely used in the medical field, even if today, their usage is more rare than it used to be until it was discovered that this metal is highly toxic. After all the information about liquid mercury and his compounds was known and understood, many companies stopped using it when producing certain objects. Mercury is heavily used by dentists. It is not used in its form of liquid mercury, but in dental amalgams. Thimerosal is another compound of liquid mercury being used in the vaccines, as a preservative. Mercurochrome also contains liquid mercury and is used as an antiseptic. This is banned in certain countries, but still heavily used in others. In Chinese medicine, the metal is used in a common form, as a cinnabar. The problem is that it can cause mercury intoxication and many times, instead of helping cure someone, it worsens the state of the patient.

In the United States of America, the sale of non-prescription liquid mercury thermometers was banned in 2002. A year later, the states of Washington and Maine banned pressure devices containing liquid mercury. The problem of the usage in medicines that are sold over-the-counter in the U.S. is extremely important in present. The FDA still has not enough evidence to interdict the usage of liquid mercury in eye drops, nasal sprays, laxatives or diaper-rash lotions, but this is a matter in progress.

Liquid Mercury Properties

Liquid mercury is a chemical element that has many uses and functions. It has the symbol Hg and 80 is the atomic number. In order to learn more about this element, you should know that there are certain properties that have been developed by the liquid mercury, which make it usable in various fields. The properties of the liquid mercury are divided into two major categories: physical and chemical.

One of the major physical properties of liquid mercury is that it can conduct electricity very well. It may also conduct heat, but in a way that is more reduced as opposed to other metals. In addition to this and as a difference from other metals, liquid mercury has a low melting temperature. It behaves like the noble gas elements more, rather than as a simple metal compound. The chemical properties developed by the liquid mercury are related to its ability to form suitable reactions with other chemical compounds. Several oxidising acids have the properties necessary to melt liquid mercury. Thus, by using sulfuric acid, nitric acid or aqua regia in reactions with this chemical element, you can obtain the following compounds: sulfate, nitrate and chloride salts. This element also reacts with hydrogen sulfide and with solid sulfur flakes. Other known reactions have been connected with the properties of this substance which allow it to form amalgams and isotopes. The amalgams can be formed in compounds with gold, zinc and other metals. In the case of isotopes, there are seven different types of compounds that can be formed.

The liquid mercury can combine in numerous reactions. These are established by the base elements that are created through its physical and its chemical properties. All the resulting compounds were elaborated in order to be used in all sorts of fields and processes in medicine, the production of chlorine, laboratory reactions, the production of caustic soda and in some cosmetics. However, it is highly advised that you inform yourself on the toxicity and safety issues necessary for working with this chemical element, before taking any sort of action with it.
