Common Sickness Experience by Seafarers

It 's bad or infectious bacteria that cause illness as they rapidly reproduce and produce a toxin that kills or mutates cells, bacteria is also self sufficient.

“Poison from the air” is nitrogen from the atmosphere that we are using unnaturally; fertilizers run off into water and have ecological effects and nitrogen was used for chemical warfare in World War I.

Most times when we think of poisoning, we think of humans. Animals are also poisoned. There is an Animal

Toxicity is the amount of degree of damaging a organism because of a substance. Toxicity can effect many things like plants, animals, and bacterium. Also as the effect of substructure of a organism, just like a cell or a organ such as its liver. In chemistry, pH is a numeric scale used to specify the acidity or basicity of an aqueous solution. Pollution is a substance that is harmful and or poisonous affects on the environment. But many things can be effected by pollution like plants and animals. Also humans are effected by pollution. Air pollution over time effects humans which can lead to many diseases and cancer such as lung cancer. Water pollution is water that is contaminated. The oceans pollution is mostly caused by sewage and waste water. All water has or will have pollution in them like lakes, rivers, oceans, swaps, creeks, aquifers and groundwater.

There are two main types of toxicity, acute and chronic. Acute toxicity refers to a relatively high dose of a toxin given over a short period of time. Chronic toxicity is a relatively low dose of a toxin given over a longer time period. Acute toxicity is measured by the Lethal Dose 50 (LD50). LD50 is the dose of a specific substance that kills 50% of test organisms, and it varies from substance to substance.

In 1834, a stranded Antarctic polar expedition went missing the only records that give insight into the expedition give evidence to suggest the sailors were under extreme biological heartache. The task was to analyse: Newspaper articles, photographs, site maps, journal pages and a detailed list of supplies to determine the common thing that killed five people. Possible causes of death include: Antimony, Aquavit, Influenza, Phlebotomy, Plague, Polio, Rabies, Scurvy, Yellow fever or the underlying statement of there was no cause. The purpose of the report is to determine exactly what disease killed the men and women on the expedition.

A chemical hazard is any exposure to a chemical substance, this can include; acids, drugs, gases or any toxic substance. In a pathology lab, these hazards can occur when working with samples and producing new vaccines and drugs.

Cobra venom is one of the molecules that interfere with human body functioning. The molecule hinders the interaction of body molecules such as acetylcholine - transmitted from the ends of the nerve surrounding the diaphragm muscle – with the sites of the receptors on the diaphragm

The Poisoner’s Handbook focuses only on a few of these, organization, cause and effect, and diversity. Although the book is organized like a textbook, it is by far the easiest to read especially for people who truly love this topic. Although the effect of each poison is the same, eventual death, the cause varies for each poison depicted from dosage to length and severity of symptoms. The handbook goes into the diversity of poison ranging from plants and animals to chemicals and where they can be found, some in the U.S. while others in more exotic places like

It may be noted here that tarantula venom is currently the subject of a wide variety of scientific research. Live specimens are needed at research centers. Recent studies reveal that peptides in the venom may provide the key to discovering long-range cures or treatments for MS and heart disease in humans. Tarantula venom varies widely in chemical composition and their effects on people. Other than routine concerns over a small puncture wound, bite symptoms range from none to mild swelling and pain depending upon the individual. The most important distinction for tarantulas is they do not cause human deaths. Scorpion and bee stings are accountable for many deaths, thus are more worthy of special handling procedures and earning the label

This is an infectious disease. Infectious diseases are disorder that are caused by organisms such as, viruses, bacteria, parasites, or fungi. Some infectious diseases can be passed from human to human

Seasickness is a terminology describing an illness that caused by an effect of motion, experienced by an individual particularly at sea. Seasickness can be a serious problem for sailors. Not only does the sick person feel terrible and become incapacitated, and therefore a problem too for others on a shorthanded boat, but the dehydration that may result from repeated vomiting can become a medical issue. About 90% of people will experience seasickness or motion sickness at some point in their lives. If you're new to sailing, or have ever experienced nausea or dizziness on a boat, it's worthwhile to take steps early to prevent seasickness. Once seasickness occurs, it's too late to do much more than cope with it as best you can.

Toxic chemicals are extremely hazardous to the oceans. Three of the most deadly chemicals are constantly running off land into water. These chemicals; DDT, PCBs, and dioxins belong to a family of industrial and agricultural chemicals that do not brake down easily in our environment. When these chemicals enter the ocean they are first absorbed by phytoplankton and zooplankton. These planktons are an important part of a fish?s diet, therefore; fish eat

Chemical Hazards Chemicals are both naturally occurring and man-made. From the environment, exposure to chemical agents in our air, water, food and soil, have shown to be hazardous to human health causing cancer and lung disease, metabolic issues, brain damage, and even birth defects. Essentially, these chemicals act as toxins and poisoning, also playing a role in infectious diseases and causing the body's immune system to break down. The World Health Organization, for instance, believes that billions of people are exposed to chemical hazards on a regular basis (solvents, acids, pesticides, etc.), but at different levels and differing levels of toxicity and over differing periods of time. The exposure rate, especially from heavy metals and agricultural waste and products, seem to be the most serious over time, but even such products as led and arsenic can cause cancers that are serious and attributable to environmental standards (World Research Institute, 2000).
