1 Anthropogenic Factors And Human Health 7
Marc DesJardin Western Oregon University
ABSTRACT
INTRODUCTION
CONSEQUENCES OF THE POLLUTANTS
Anthropogenic factors are man made changes to the
environment. These changes can be building a road
in the mountains, paving over a forest or field
for urban expansion, digging a mine shaft or
strip mining. The changes can also producing a
new chemical that nature can not deal with. The
changes that mankind is making to the
environment are not without their consequences.
Anthropogenic releases of chemical contaminants
into the geologic environment can cause
significant health effects in humans and degrade
ecosystems as a whole. The destruction of our
natural resources for the expansion of
urbanization and the pollution that urbanization
creates could eventually be the fatal blow for
mankind. Toxic releases have been associated with
cardiovascular disease, malignant tumors, trauma
and genetic anomalies. Polluting agents such as
pesticides, heavy metals, petroleum compounds and
industrial residues stimulate negative health
feedbacks in the environment. Mankind is
poisoning itself through environmental
manipulation that leads to toxic releases that
eventually work their way through the food chain
back to mankind. This project examines the range
of human-induced health risks including
radiation, chemical releases, electromagnetic
fields, soil contamination, agricultural
degradation, and pollution.
- Due to Mankind's ignorance here are some of the
courses the environment is taking - Mechanisms of Toxic Action-when chemicals enter
an organism but poisoning does not occur until
the chemical has reached a harmful amount. - Ecotoxic action-when a chemical causes damage to
an ecosystem by killing organ - Combined Action of Pollutants-the environment
houses many types of chemicals the problem comes
when these chemicals combine to become toxic - Basic Mechanisms of Mutagenis-genetic mutations
are increasing at an alarming rate in humans.
These mutations have been know to lead to
malignant tumors, which are responsible for the
deaths of a fifth of the worlds population - Threat to the survival of individual species and
the organisms dependant on them
WATER POLLUTION
- Mankind is deteriorating the quality and quantity
of fresh water due pollution by - Chemical components
- Heat
- Bacteria
- Industrial Waste
- Pesticides
- Fertilizers
- Heavy Metals
- Petroleum products
- Most of the pollution caused by petroleum
products comes from oil wells and refineries.
About 2 of all the oil produced is lost usually
during becoming a serious threat to ground and
surface water.

GROUND POLLUTION
- Mankind is poisoning the flora and fuana that it
eats through the use of - Pesticides
- DDT-was used worldwide especially during WWII as
an insecticide. DDT was heavily used until the
1960s its toxicity was discovered and it was
taken off the shelves. What made DDT so good at
killing bugs is also what makes it so bad. DDT is
a very stable compound and moves very well
through out the environment. - Fertilizers
- Heavy Metals
- Elements such as mercury, arsenic, cadmium, lead,
chromium, nickel, zinc, antimony, fluorine and
uranium all are deadly is large amounts. - Mining
- Changes to morphological properties of the
terrain - Changes in the rate of exogenous processes
- Landslides, rockfalls and gulley erosion
- Destruction of flora and fauna habitats through
strip mining - Changes to the hydrological properties of the
terrain - Patterns of drainage, pollution of streams and
surface water
