So how varied are terror attack possibilities nowadays?

R.Kazimoto

We have witnessed enough varieties of terrorist attacks now such that maybe it is safe to assume a capability to predict. Before September 11 no one could imagine a scenario where an airplane could be hijacked and be used on a suicide mission involving the loss of thousands of innocent lives. Now that possibility is there and much more. A nuclear attack can not be excluded, but it requires much more complex technology and organisational capability (terror networks are quite highly organised though). But there are far simpler scenarios which are equally grim.Think of the truck that rammed into a group of people in France and killed 84 just yesterday.
 Now imagine introducing a cyanide to the water supply system of a major city!!, I am sure a lot of cities around the world do not have the capability to detect deadly poisons in their water supply in an instant and block the flow before it reaches consumers!, how are we prepared for such an easy to implement yet deadly attack which does not even necessitate suicide? 
So many poisonous agents exist which are cheap and easily available as well as readily soluble in water.Think about it!

Instances of unsafe salt intake levels

It is currently a well known fact that high salt intake is harmful to our bodies. But we do not generally consume salt as food but merely as a food additive. So logically, there being various forms of food there oft to be some that go together with just much more salt in comparison to others.
A serving of lean beef would not require as much salt as the same amount of fatty beef, such as hump, the fat content tends to lean towards nausea and salt acts as mediator enabling easy ingestion. Speaking of meat, brain and intestines also tend to need more salt to enable one to eat them.
Eggs, especially boiled ones have the same tendency.
But all these food types have one thing in common, according to common knowledge, they cause heart conditions, now the question arises is it not the salt that goes together with these foods that is the main culprit here?
Case in point: the Maasai herdsmen of East Africa consume a lot of fat meat in their range lands but they do not have heart conditions at the same levels as the global average, they on the other hand have a problem with availability of salt in their grazing areas so their salt consumption is minimal.
Please nutritional researchers go to work!!

Not all nitrogen bearers are food!

Beware, the most simple test for proteins,  Kjeldahl,  involves decomposing suspect samples in boiling hot Sulfuric acid to release organic Nitrogen as Ammonium Sulfate which is then transformed into Ammonia and titrated to quantify N.
This method declares the amount of Nitrogen in the analyte sample and works on any compound containing N.
But then Melamine, as an example has 67% by mass N and is not a protein and worse still it is harmful if consumed. The Kjeldahl test works just fine in determining N in Melamine and is the culprit in a number of Chinese food contaminant cases, since it was relied too much in determining proteins in food by way of estimating N in the past unscrupulous companies added melamine to baby milk and animal feed to fake an abundance of proteins.
The best milk for your baby may well be direct from a cow you raise or feed yourself if you can not trace the origins of what your baby eats.

Health hazards exposure to road repair manual labourers

Hello everybody,
As our youth are struggling here and there looking for a job of one form or another, care should be taken on the kind of occupation that they engage in.Some unscrupulous construction companies "specialize" in small civil works such as periodic road repairs which are labour intensive because they have a tendency to prey on easily available unskilled labourers from the general public, such companies generally refuse to grow for the simple fact that it pays more where they are as rules and regulations that govern construction companies of higher grades affect them the least.
One could dwell on the amounts of remuneration paid to the said labourers and make enough of a story but this is about their well-being.
In repairing pot holes in paved roads they boil bitumen to melting point and mix it with aggregates to make patches on the road, the bitumen, or tar, is boiled in open trays made of metal sheets and is stirred constantly using wooden sticks to make it melt uniformly. After melting it is scooped out using ladles and poured in steel buckets and then transferred to the potholes.

Boiling bitumen issues vapours that contain Poly-cyclic Aromatic Hydrocarbons or PAHs. At 160 to 250 degrees centigrade range of temperature, where bitumen is in molten form, the following PAHs are contained in its vapours;-

  1. Phenanthrene
  2. Anthracene
  3. Fluoranthene
  4. Pyrene
  5. Chrysene
  6. Perylene
  7. Benzo[k]fluoranthene
  8. Benzo[a]pyrene
  9. Benzo[g,h,i]perylene.
These compounds exist in various concentrations in bitumen vapour but all of them are proven causes of several types of cancer if inhaled.It is not possible to work on road repair in the conditions at which the small companies in question operate without inhaling the fumes directly because one reason these companies refuse to grow is so that they can evade OSHA regulations, such as wearing breathing masks for their workers.
It is important that the public is aware of these health hazards so that pressure can be built to push the government into looking on how to force these companies to comply with the rule of law, otherwise we stand to loose a considerable number of our youth by cancer and other related diseases.
