1

bitter almonds

cyanide

2

friity

diabetic

3

garlic

organophosphates, arsenic, DMSO

4

mothballs

naphthalene, camphor

5

how often do patients with CO poisoning turn red

not very often but it does cause blood to be very red even though its not carrying oxygen

6

what poisoning often happens in conjunction with CO poisoning

cyanide poising because of the burning furniture in fires.

7

what is ment by heavy metals

metals or metalloids of environmental concern, denser than iron

8

Do radioisotopes bioconcentrate

yes, they do as they are eaten and move up the food chain.

9

before what date should things not have cesium?

before 1924

10

how can you increase toxicity of HG

methylate it and it becomes more water soluble and can cross the BBB.

11

what are the two main toxicities of mercury poisoning?

neruotoxicity (brain) and nephrotoxicity (kidney

12

is arsinic always poisonous?

no it can be in some species genome

13

what does acure arsenic poisoning cause?

CAN toxicity and hemorragic gastroenteritis

14

what does chronic arsenic cause

malaise, abdominal pain, skin changes, mees lines.

15

mees lines arsenic

horixontal white lines on nails

16

what do lead lines look like

they are not on nails they are at the gingivodental line

17

why is lead worse for children

CNS toxicity,

18

Pica

desire to eat dirt or ice, may be genetic condition

19

basophilic stippling?

seen with microcytic anemia in lead poisoning. Ribosome are spread showing small dots at periphery

20

why do those who start smoking at 30+ not get COPD

because they thart after epithelial transition ends at about 20. this also makes it so that cumulative effects take longer

21

what is the 20 pack year thing.

packs per day times years smoking. 20 = cancer in the othd view.

22

what illness can second hand smoke cause in children

sids, otitis media and asthma/URI

23

what is photochemical smog?

chemical reaction of sun, NO, and VOCs in atmosphere leading to ground level ozones and particles and aldehydes, Nos

24

what was in smog in 1905?

soot, and sulfer from burining coal

25

how is ozone formed?

in atmosphere when NO is broken by sun, and some os for osone.

26

why is silicosis the most common pneumoconiosis?

caused by inhalation of dust or pollutants in smok with silica

27

sillicoderosis

inhale dust and sillica, swelling of lungs

28

caplans syndrome

swelling and scarring of the lungs of people with rheumatoid arthritis...pneumoconiosis in combination with multiple pulmonary rheumatoid nodes found in rheumatoid arthritis.

29

silicates

adding another atom to silica to make mineral

30

silicon

chemical element, but almost always in combo with O2

31

silicone

polymer of silicone with C and O. solid liquid or gel

32

Pathogonomic

symptom/sign that is character of diesase, that will tell you a specific disease without a doubt

33

what is eggshell calcification

indicates silicosis on an xray, it is pathogonomonic

34

why does inhaling particles cause fibrosis?

magrophage igestion trigger frbrogenic respons via growth factors, promote collagen deposition

35

where do asbestose fibers localize

in septum of alveolus and distal lung.

36

what are asbestosed fibers in lungs cause

rod or dumbell shaped

37

cancer of asbestose

mesothelioma that involves lower lobes and pleura

38

asbestose exposure increases lung cancer by how much

5 times then 55 times if the ysmoke to.
