This document discusses a study on the heavy metal lead (Pb) and its effects on air and water environments. It begins with an acknowledgements section and background on lead being a toxic substance that can pollute the environment through air or water. The formulation section outlines questions on defining lead, its nature and characteristics, types of lead, sources of lead, benefits of lead, and how lead impacts air and water environments. Later sections define lead, describe its characteristics, types including galena and cerrusite, sources such as nature, food, transportation and industry, benefits including uses in automotive and industrial applications, and impacts like air and water pollution from vehicle emissions and industrial waste discharge. References are provided to conclude the document.

3. Background
Lead is a substance or substances that are
harmful to the environment. The entry of
metallic lead to pollution of the
environment can cause either to air or
water..
to know what heavy
metals lead (Pb) and
the influence or impact
on the environment of
air and water

4. Formulation
What sense Timbale Metals (Pb)?
What is the nature and characteristics of the metals Lead
(Pb)?
What types of heavy metals Lead (Pb)?
Where the source of heavy metals Lead (Pb)?
What are the benefits of the heavy metals lead (Pb)?
How to influence or impact caused by heavy metalsLead
(Pb) against environmental air and water?
To learn more about what is meant by
heavy metals lead (Pb) and the
influence or impact on the marine
environment.

6. DEFINITION
Lead is a heavy metal
containing toxic
substances (toxins). with
it timbale is logan that
should receive more
attention in order to
minimize the inclusion of
lead both to humans and
to the environment
(Deri, 2013)
Pb lead the Latin word
plumbum which means
soft metal. Lead is one
of the air pollutants in
the form of
particulates.
(Arisandy, 2012).

7. CHARACTERISTICS
Character
Lead (Pb)
The atomic number 82
Inorganic (inorganic salts)
Bluish gray color
Boiling point 1620
Soft and supple
(Denny,2005)

8. TYPE
Lead (Pb)
Galena
Lead is a mineral that is
very important and most
widely spread across the
hemisphere and is
generally associated with
other minerals such as
sphalerite, calcite, and
flourite
Cerrusite
is one of the minerals of lead
containing lead carbonate and
become the main source of lead after
galena
Anglesite
is a mineral of lead from
lead sulfate PbSO4

9. SOURCE

Food
Transportation

10. BENEFIST
Widely
used in the
automotive
field
As a coloring
agent in the
manufacture of
ceramics,
especially for
yellow and red
PVC plastic
is used in
the industry
to cover the
electric
wire
Used to
solder for
the
electronics
industry.
Added in
equipment made
of brass that is
not slippery and
is typically used
in machining
equipment
(Wulandari,2005)

11. The Impact
Timbal (Pb)
Air pollution water pollution
Vehicle exhaust fumes can be an
indicator of the cause of pollution
in the air due to the substance or
substances Lead metal produced.
Industrial waste water
discharged directly into the
water can cause water
pollution.
