A substance is considered extremely toxic if it has an LD50 of less than 5 mgs/kg of animal body weight. To humans, this is the equivalent of a taste (less than 7 drops). It is Highly toxic if it has an LD50 of between 5 and 50 mg/kg of animal body weight to a human, this would be about a teaspoon.
Radon in basements, lead in drinking water, exhausts from cars and chemicals released from landfills are just a few examples of toxic substances that can hurt you.
Types of toxicity
There are generally three types of toxic entities; chemical, biological, and physical. Chemicals include inorganic substances such as lead, hydrofluoric acid, and chlorine gas, organic compounds such as methyl alcohol, most medications, and poisons from living things.
Routes of Exposure
There are four routes by which a substance can enter the body: inhalation, skin (or eye) absorption, ingestion, and injection.
There are generally five types of toxicities; chemical, biological, physical, radioactive and behavioural. Disease-causing microorganisms and parasites are toxic in a broad sense but are generally called pathogens rather than toxicants.
Be honest about how the toxic trait impacts you
As we mentioned, many people don't realize they have toxic traits. So, telling someone that their actions have hurt your emotional well-being may help them understand they need to change.
Toxic behavior definition refers to a person whose behavior and ongoing actions cause harm to other people by physical or mental means. These are the people who spread negative or toxic stress or traumas on others behavior.

Abstract. Botulinum toxins, exotoxins of Clostridium botulinum, are the most toxic naturally occurring substances known to man.
Some of the most common toxic traits include abusiveness, manipulation, being judgmental, dishonesty, and being generally unkind to others.
A toxic LOC tells you what level (threshold concentration) of exposure to a chemical could hurt people if they breathe it in for a defined length of time (exposure duration). Generally, the lower the toxic LOC value for a substance, the more toxic the substance is by inhalation*.
In some cases, toxic behavior may stem from underlying psychological issues such as anxiety, depression, or borderline personality disorder. People with these conditions may engage in toxic behavior as a way to cope with their own emotional struggles.
This doesn't mean you have to interact with them, but people aren't born “toxic” and generally get that way from observing such behavior in the home as a child or experiencing abuse. Setting healthy relationship boundaries with toxic people is essential, although it can be very challenging.
Overthinking strikes all of us at some point, but if it goes unchecked and unresolved, overthinking can certainly morph healthy relationships into toxic relationships. If you fall victim to your thoughts and allow them to go too far, they can end up driving a wedge of distrust between you and other people in your life.
If a relationship stops bringing joy, and instead consistently makes you feel sad, angry, anxious or “resigned, like you've sold out,” it may be toxic, Glass says. You may also find yourself envious of happy couples. Fuller says negative shifts in your mental health, personality or self-esteem are all red flags, too.
It relies on the concept that a dose, or a time of exposure (to a chemical, drug, or toxic substance), will cause an effect (response) on the exposed organism. Usually, the larger or more intense the dose, the greater the response, or the effect. This is the meaning behind the statement “the dose makes the poison.”
In addition to breathing out, we remove toxic products through urine, feces, and sweating.
