00:00:02.160 --> 00:00:05.500
We're heading back to Breaking Bad. Could a chemistry mistake
2
00:00:05.599 --> 00:00:09.660
really create mustard gas? In the opening episode of Breaking Bad,
3
00:00:09.699 --> 00:00:12.480
Walter White is still a high school crest chemistry teacher,
4
00:00:12.500 --> 00:00:14.400
but his knowledge of chemistry is about to take a
5
00:00:14.460 --> 00:00:18.230
dangerous turn. While explaining the risks of producing methamphetamine, he
6
00:00:18.269 --> 00:00:21.149
warns Jesse Pinkman that a mistake could create mustard gas.
7
00:00:23.050 --> 00:00:27.390
It's a memorable warning, but how scientifically accurate is it? Well,
8
00:00:27.429 --> 00:00:29.230
first we need to do is understand what mustard gas
9
00:00:29.329 --> 00:00:32.929
actually is. Despite its name, mustard gas is not ordinarily
10
00:00:32.969 --> 00:00:35.149
a gas at room temperature. It is an oily liquid
11
00:00:35.189 --> 00:00:39.009
that can evaporate into dangerous vapor. Chemists call the best-known
12
00:00:39.109 --> 00:00:42.520
form sulfur mustard, a chemical warfare agent infamous for its
13
00:00:42.759 --> 00:00:45.979
use during World War I. Unlike the nerve agents often
14
00:00:46.000 --> 00:00:49.079
depicted in movies, sulfur mustard primarily attacks the skin, eyes,
15
00:00:49.140 --> 00:00:53.259
and respiratory system, and is considered classified as a blister
16
00:00:53.359 --> 00:00:57.039
agent because exposure can produce severe chemical burns. The most
17
00:00:57.079 --> 00:01:01.060
frightening characteristic is that symptoms may not appear immediately. So
18
00:01:01.100 --> 00:01:07.359
someone exposed to sulfur mustard might initially feel normal. Hours later,
19
00:01:07.459 --> 00:01:11.500
painful injuries can develop as damage to cells and tissues
20
00:01:11.540 --> 00:01:17.280
become apparent. The explanation involves molecular biology. You see, sulfur
21
00:01:17.319 --> 00:01:21.000
mustard is an alkalizing agent, meaning it can chemically modify
22
00:01:21.040 --> 00:01:26.579
important biological molecules, including DNA. These reactions disrupt cellular function,
23
00:01:26.659 --> 00:01:32.200
trigger inflammation, and can eventually cause cell death. But could
24
00:01:32.239 --> 00:01:35.620
a mistake in Walter White's lab actually create mustard gas?
25
00:01:35.859 --> 00:01:39.640
Not simply because someone mixed chemicals incorrectly. Sulfur mustard has
26
00:01:39.700 --> 00:01:43.530
a specific molecular structure and its formation requires particular chemical conditions.
27
00:01:44.329 --> 00:01:48.670
It is not a generic byproduct of methamphetamine production. However,
28
00:01:49.150 --> 00:01:53.859
Walter's broader warning about dangerous chemical reactions is legitimate. Improperly
29
00:01:53.920 --> 00:01:57.859
managed chemical processes can release toxic vapors, create fires, or
30
00:01:57.900 --> 00:02:02.000
produce violent reactions. Illicit drug labs are especially hazardous because
31
00:02:02.099 --> 00:02:07.909
operators may work without appropriate ventilation or protective equipment. The
32
00:02:07.950 --> 00:02:11.150
historical connection is also very interesting. During World War I,
33
00:02:11.530 --> 00:02:14.569
chemical warfare transformed the battlefield. Soldiers faced threats that could
34
00:02:14.590 --> 00:02:17.969
not easily be seen, and military forces developed protective masks
35
00:02:18.830 --> 00:02:22.719
and specialized training for operating in contaminated environments. Today, military
36
00:02:22.750 --> 00:02:27.879
units still prepare for chemical, biological, and radiological threats. That
37
00:02:27.919 --> 00:02:32.340
history provides an excellent example insight into how soldiers recognize
38
00:02:32.360 --> 00:02:35.900
chemical hazards. Yet the most interesting part of Breaking Bad
39
00:02:35.939 --> 00:02:37.439
may not be the chemistry at all. It may be
40
00:02:37.490 --> 00:02:41.189
Walter White himself. Walter White begins the series presenting his
41
00:02:41.229 --> 00:02:45.009
criminal decisions as sacrifices made for his family. And we'll
42
00:02:45.050 --> 00:02:48.250
probably explore that more on my other podcast, Forensic Psychology.
43
00:02:50.389 --> 00:02:53.909
Chemicals do not, again, become dangerous simply because someone intends
44
00:02:53.949 --> 00:02:56.469
to do something illegal. Their properties remain the same regardless
45
00:02:56.509 --> 00:03:04.810
of who handles them. What changes the environment... So, was
46
00:03:04.849 --> 00:03:09.479
Walter right? Well, it depends. It's not simply because of
47
00:03:09.560 --> 00:03:12.400
mixing chemicals. And maybe he could have led to the
48
00:03:12.439 --> 00:03:16.819
wrong territory for it. I don't know. So, to answer
49
00:03:16.860 --> 00:03:23.479
the question, was Walter right about... Well, not exactly. The
50
00:03:23.500 --> 00:03:25.699
real hazard of Breaking Bad is what they call phosphine,
51
00:03:25.740 --> 00:03:28.550
not mustard gas. Phosphine is a highly toxic gas that
52
00:03:28.569 --> 00:03:33.030
can be produced accidentally during certain methods of methamphetamine manufacture.
53
00:03:33.599 --> 00:03:36.689
It's not simply the result of mixing methamphetamine itself with something.
54
00:03:37.539 --> 00:03:40.330
In the early RV scene, Walt creates a poisonous gas
55
00:03:40.389 --> 00:03:42.969
and later identifies it as phosphine. The danger is real,
56
00:03:43.009 --> 00:03:47.189
but the chemistry shown, thankfully, is misleading. There's also a
57
00:03:47.270 --> 00:03:51.229
mix-up about household chemicals. Mixing bleach with ammonia produces toxic
58
00:03:51.250 --> 00:03:55.009
chloramine gases, not mustard gas. Mixing bleach with an acidic
59
00:03:55.030 --> 00:03:59.270
cleaner can release chlorine gas. These are dangerous, but they
60
00:03:59.310 --> 00:04:04.039
involve different chemicals and nothing like mustard gas. So unfortunately,
61
00:04:04.300 --> 00:04:07.550
not completely accurate, a little bit different, and probably for
62
00:04:07.610 --> 00:04:09.659
legal reasons. And that makes sense.
