Diseases and the workplace

A. Industries and industrial areas

South Africa is a reasonably prosperous country, especially if measured against African standards. An investigation into the prevalence of minerals and raw materials that are derived from the fishing industry, agriculture and forestry will indicate that these are the origins of our prosperity.

The products of our mining industry, and the raw materials referred to above, are processed in factories in order to add value to primary products and in the process, ultimately to create prosperity in the country. The numerous work opportunities that are created in factories, and the wages and salaries that are earned by factory staff, help to produce greater wealth among all sections of the population.


In South Africa, as in most other countries in Africa, there is great unemployment. Any steps that are taken to create employment are welcomed. At one stage the Ceres group wanted to donate land to a fruit canning company in order to create jobs and increase productivity.

However, it would be foolish to do everything in one’s power to utilise the country’s raw materials as speedily as possible and to forget about the people and the environment .

In man’s endeavours to make money out of mining and agriculture, he does a great deal of good, but some of his decisions do not take the best interests of the people and the environment into consideration. One frequently reads and hears about court cases that are made against governments and companies in order to call them to account for past wrongs.

The countries in eastern Europe that were under the rule of the USSR for about 40 years before they took control of their own affairs in 1990 are good examples of how a government can ruin a country. At a certain stage the smoke from thousands of factories in these countries contained so many harmful substances that the trees started to die. Effluent that was spilled into the Rhine, Europe’s largest river, began destroying many kinds of plant and animal life in the early 1970s.

Activity 1:

To make deductions from a graphic representation

[lo 3.1; 3.3]

  • Study the drawing and explain the good plan that was devised to prevent water pollution in this river:

What was the plan that was devised?

B. The influence of industries

It is not only nature that is influenced by industries, but also the people who work in the industries.

Activity 2:

To identify and analyse problem situations and to make recommendations for their improvement

[lo 3.1; 3.3]

Study the newspaper reports and complete the questionnaire:

Report 1

Asbestosis victim blames unicity of dragging their feet

Helen Coetzee

CAPE TOWN - The unicity is dragging its feet while employees at the Athlone power station are suffering from lung cancer and asbestosis that they developed from inhaling asbestos fibre.

Translated from Die Burger, 26 June 2001

Report 2

Prieska speculates about who lie buried at the mine dump

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
in general
Graphene has a hexagonal structure
On having this app for quite a bit time, Haven't realised there's a chat room in it.
what is biological synthesis of nanoparticles

types of nano material
abeetha Reply
I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
I'm interested in nanotube
what is nanomaterials​ and their applications of sensors.

what is system testing?
preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
how did you get the value of 2000N.What calculations are needed to arrive at it
