2. Lead (Pb) |
< 1000 ppm |
3. Mercury (Hg) |
< 1000 ppm |
4.
Hexavalent

ppm :ppm = parts per
million, unit of measurement for weight percentage. 1 ppm = 1 mg/kg
=0.0001 % by weight. |

How The Hazardous Substances Affect Human | |
1. Cadmium (Cd) |
The main human health effects
include renal dysfunction, growth disturbances, skeletal damage and
reproductive deficiencies. Cadmium is also suspected of causing liver,
lung and prostate cancer. |
2.
Lead (Pb) |
Lead can have toxic effects
on the endocrine and central and peripheral nervous systems, and cause
brain damage in children./ Lead is known to cause damage to the central
and peripheral nervous systems, blood system and kidneys in humans.
Effects on the endocrine system have also been observed and its serious
negative effects on children's brain development have been well documented. |
3. Mercury (Hg) |
It can cause chronic damage
to various organs including the brain and kidneys as well as the fetus. |
4.
Hexavalent
Chromium (Cr 6+) |
It
causes strong allergic reactions even in small concentrations. Asthmatic
bronchitis is another allergic reaction linked to Chromium VI. Chromium
VI may also cause DNA damage. |
5.
Polybrominated
Diphenyl Ethers
(PBDE)
|
Affect
liver enzyme production, negatively affect thyroid hormone system and
induce immunotoxicity. Induce neurotoxicty when administered at sensitive
period of brain growth. |
6.
Polybrominated
Biphenyls (PBB) |
