i.
Environmental pollution
Environmental pollution
This
is as a result of accumulation of sawmill wastes which consist of saw dust,
wood off cut, wood back, wood rejects, and plain shaving over a long period,
which degrade the natural environment, reduces its aesthetic value, causing
unsightliness, and constituting bad working environment for the sawmill
workers.

ii. Air pollution
This
is as a result of burning of waste uncontrollably. The smoke contaminate the
air which causes reduction in visibility, emission of green house gas especially
methane (CH4) and carbon monoxide, leading to the disruption of
normal flow of oxygenated blood to body organs and tissues which at extremely
high level causes death.

iii. Odour nuisance
This
occur when the accumulated waste is wetted by rain due to defective final
disposal method and inadequate management of waste which is characterized by
stinking smell, discomfort, irritation and nausea to man.

iv. Insect and helminth infestation
This
is due to the untimely disposal of waste generated in the sawmill industries,
thereby becoming breeding site for insect and worm leading to several health
problem which could trigger off some painful symptom such as severe itching,
restlessness, and irritability, abdominal pain, nausea and vomiting.

v. Diseases
Diseases
such as skin rashes, skin burns, asthma, frequent headache, chronic cough,
hypersensitivity, peritonitis, chronic obstruction of lungs, liver and kidney
as a result of inhalation and contact with wood dust, and chemicals use in the
industry.

Noise pollution
Noise pollution
Exposure
to excessive loud noise from sawmill machines over a long period can lead to
partial or permanent deafness, aggression, higher stress level, tinnitus, and
hypertension.
