How toxicity can affect the human body.

A toxin is a harmful substance producing within living cells or organisms and vary depending on their toxicity from the minor to the almost immediately deadly.

There are five types of toxic entities that is biological,chemical,radiation,behavioural toxicity.

Some examples of toxins are;

*Botulinum toxin A-it is produced by the bacterium clostridium Botulinum and prevents the release of the neurotransmitter acetylcholine from the axon endings thus causing partial paralysis.This toxin causes the disease botulism.

Abdominal pain, constipation, nausea, drooling,dizziness,difficulty speaking are some of the symptoms of botulism.

*Tetanus toxin A-it is a bacterial protein toxin produced by the clostridium tetani which binds to the receptor complex at the neuromuscular junction.It causes tetanus.Fever,high blood pressure,nervous system dysfunction,muscle spasms and stiff muscles,shortness of breath are some of the symptoms of tetanus.

*Muscarine-it is a natural alkaloid that is found in a number of wild mushrooms.Excessive sweating,blurred vision,nausea,vomiting,diarrhoea are some symptoms of a muscarine poisoning.

*Diptheria toxin-it is produced by toxygenic starins of corynebaxterium diptheriae which kills cells by inhibiting eukaryotic protein synthesis and causes the disease diptheria.Chills,fatigue,fever,hoarseness,runny nose,swollen lymph nodes are some of the symptoms of diptheriae.

*Bufotoxin-a poison released by the skin of amphibians especially the toad.Seizures,arrhythmia,profuse salivation,vomiting,pawing at mouth are some of the symptoms of a bufotoxin poisoning.

*Ochratoxin-a naturraly occuring food borne mycotoxin found in a wide variety of agricultural products.Depression or low mood,fatigue,brain fog,rashes,IBS,kidney problems are some of the symptoms of ochartoxin poisoning.

Most of these toxins are formed naturally and are as a result of

*Growth under stressful situations.

*Abuse of harvesting,cultivation or transport conditions.

*As defensive mechanisms of plants

*Through infestation with toxin producing mould,

*Personal care products like shampoos,

*Ingestion by animals of toxin producing micro organisms.
