24
Q

Refers to the effect of a chemical exposure that will produce injury to one kind of living organism but has no effect to another closely related living organism

A

Selective toxicity

25
Q

Dose or exposure level below which the harmful effects of the chemical are not seen in a population

A

Threshold dose

26
Q

No observed adverse effect level (NOAEL) or the no effect level (NEL)

A

Threshold dose

27
Q

This may not be applicable to cancer-causing substances since there is no safe level of exposure for these substances.

A

Threshold dose

28
Q

Refers to the fatal effects of toxins to the body after exposure through the different routes with a chemical.

A

Toxic

29
Q

Any chemical that can injure or kill humans, animals, or plants; a poison.

A

Toxicant

30
Q

Produced by or are a by-product of human-made activities

A

Toxicant

31
Q

Endogenous substances that are produced naturally in living organisms

A

Toxins

32
Q

The degree to which a chemical substance damages an organ system, disrupts a biochemical process or disturbs an enzyme system

A

Toxicity

33
Q

Amount it takes to elicit a toxic effect compared with other chemicals

A

Potent

34
Q

Done for some toxic exposures (blood lead levels or metabolites of chemicals)

A

Biologic monitoring

35
Q

These influences toxicity of the substance and its dose as it enters the body

A

Site
Route of exposure

36
Q

The fastest route for toxins to enter the systemic circulation, produces toxic effects throughout the body

A

Inhalation

37
Q

Intravenous, intramuscular and subcutaneous injections are some of the examples

A

Injection

38
Q

This is more permeable to fat-soluble chemicals that water-soluble once.

A

Skin

39
Q

any exposure less than 24 hours up to 72 hours

A

Acute exposure

40
Q

Toxic gases require how many hours for toxicity?

A

less than 24 hours

41
Q

Repeated exposures to a substance for greater than 72 hours but less than 1 month.

A

Subacute exposure

42
Q

This refers to continuous or repeated intermittent exposure

A

Chronic exposure

43
Q

a period of exposure extending beyond 3 months.

A

Sub chronic exposure

44
Q

This is the cumulative action of a chemical or a xenobiotic’s absorption, biotransformation and elimination

A

Disposition

45
Q

A process where toxicants cross body membranes and enter the bloodstream

A

Absorption

46
Q

What are the main sites of absorption?

A

GI tract
Lungs
Skin

47
Q

Most common cause of unintentional exposure to a toxicant

A

Accidental ingestion

48
Q

The common cause of intentional overdoses most frequently occur via

A

Oral route

49
Q

The phenomenon of the removal of chemicals in the liver before entrance into the systemic circulation

A

First-pass effect

50
Q

The absorption of the toxicant depends on its physical properties, such as

A

Solubility
Dissolution rate

51
Q

This acts as a primary barrier since it is covered by a film of fluid which retains gas molecules if they are very water soluble or react with cell surface components.

A

Nose

52
Q

Size of particle that can penetrate the alveolar sacs of the lungs

A

1μm and smaller

53
Q

These have the greatest likelihood of depositing in the alveolar region

A

Nanoparticles

54
Q

The single most important barrier to preventing absorption of xenobiotics into the body

A

Stratum corneum

55
Q

Important factors of stratum corneum as a single most important barrier to preventing absorption of xenobiotics into the body

A

thickness
Integrity
Hydration status

56
Q

These compounds are generally absorbed quickly

A

Lipophilic (lipid-loving)

57
Q

These compounds are absorbed more slowly

A

Hydrophilic (water-loving)

58
Q

The movement of compounds through the layers of the skin is through ..

A

Passive diffusion
