What leading health agencies have to say about these smoke
"Acute exposure in humans results in irritation of the eyes, nasal passages, throat
and lungs, and causes neurological effects such as blurred vision, fatigue, headache and
vertigo. Epidemiological studies have reported a possible association between exposure and
cardiovascular diseases. [It is a] probable human carcinogen of medium carcinogenic
"The primary acute effect of inhalation exposure to acetaldehyde is irritation of the
eyes, skin and respiratory tract in humans. Erythema, coughing, pulmonary edema and
necrosis may also occur."
"Workers exposed to acetone vapours experienced transient eye and nose
"Acrolein is extremely toxic to humans. The acute and chronic effects of acrolein in
humans consist mainly of effects on the lung, such as upper respiratory tract irritation
and congestion and eye irritation."
Acute exposure via inhalation "has been observed to cause low-grade anaemia,
cyanosis, leukocytosis, kidney irritation, mild jaundice and irregular breathing, with
symptoms that include mucous membrane irritation, headaches, dizziness, nausea, feelings
of apprehension and nervous irritability. [It is a] probable human carcinogen of medium
"Ammonia can increase susceptibility to viral illness and aggravate chronic
Aromatic amines -
"Acute inhalation exposure produces headaches, lethargy, cyanosis, urinary burning
and hematuria in humans ..[it] is a known human bladder carcinogen."
"A substance declared toxic or carcinogenic to human health under the Canadian
Environmental Protection Act (CEPA)."
"There are multiple animal studies in many species demonstrating BAP to be
carcinogenic following administration by numerous routes."
"Human health effects associated with breathing or otherwise consuming small amounts
of butyraldehyde over long periods of time are not known
limited evidence shows that
butyraldehyde may cause changes in cells important to the reproductive system of
"Cadmium is much more dangerous by inhalation than by ingestion. Repeated or
long-term exposure to cadmium, even at relatively low concentrations, may result in kidney
damage and an increased risk of cancer of the lung and of the prostate."
"Acute effects are due to the formation of carboxyhemoglobin in the blood,
which inhibits oxygen intake. At moderate concentrations, angina, impaired vision and
reduced brain function may result."
"Increased the carcinogenic effects of benzo[a]pyrene on the skin in mice when
applied together dermally."
"A possible human carcinogen."
"Formaldehyde "causes acute eye burning and irritates mucous membranes and
the respiratory trace. EPA has determined formaldehyde to be a probable human
"It is among the most toxic chemicals found in tobacco smoke. Short-term exposure can
lead to headaches, dizziness, nausea and vomiting."
"Lead is a highly toxic metal. Lead is capable of causing serious damage to the
brain, kidneys, nervous system and red blood cells. Children are particularly vulnerable
because lead is more easily absorbed into growing bodies and the tissues of small children
are sensitive to its effects. Lead exposure in children can result in delays in physical
development, lower IQ levels, shortened attention spans and increased behavioural
M,p and o-cresol
"Possible human carcinogen
based on an increased incidence of skin papilomas
"Adults exposed to metallic mercury vapour may develop shakiness (tremors), memory
loss and kidney disease."

Methyl Ethyl Ketone
"Exposure to methyl ethyl ketone in humans, via inhalation, results in irritation to
the eyes, nose and throat and central nervous system depression."
"Inhalation exposure to nickel compounds can increase susceptibility to respiratory
US Department of Health and Human Services
"Produce(s) short term effects on airway activity. High concentrations can lead to
acute lung dysfunction. Special risks exist for chronic bronchitis, emphysema and asthma
in children under two years old. Chronic effects are not well established."
"Exposure to hydroquinone dust has resulted in eye injuries, which varied from mild
irritation and staining of conjunctivae and cornea, to changes in the thickness and a
curvature of the cornea, loss of corneal luster and impaired vision."
"Phenol is highly irritating to the skin, eyes and mucous membranes in humans."
"Exposure to high levels of propionaldehyde caused anaesthesia and liver damage via
"Acute inhalation exposure to quinoline vapours irritates the eyes, nose and throat
and may cause headaches, dizziness and nausea in humans. EPA has classified quinoline as a
group 3 possible human carcinogen."
"Hydrogen selenide is the most acutely toxic selenium compound. Acute exposure to
hydrogen selenide by inhalation results primarily in respiratory effects, such as
irritation of the mucous membranes, pulmonary edema, severe bronchitis and bronchial
"Chronic exposure to styrene in humans results in effects on the central nervous
system such as headache, fatigue, weakness and depression; peripheral neuropathy and minor
effects on some kidney enzyme functions and on the blood."
"Central nervous system depression has been reported to occur in chronic abusers
exposed to high levels of toluene. Symptoms include ataxia, tremors, cerebral atrophy,
nystagmus (involuntary eye movements) and impaired speech, hearing and vision. Chronic
inhalation exposure of humans to toluene also causes irritation of the upper respiratory
tract, eye irritation, sore throats, nausea, skin conditions, dizziness, headaches and
difficulty with sleep."
