Why
PCB Pollution Continues |

 |
| Waste dumping
sites can also be polluting sources. |

PCB wastes that are not yet treated should be
stored properly; those that are lost may be, in the end, carried
into waste dumping sites where they cause new problems.
Not only rubbish but also harmful chemicals are treated at waste
dumping sites; to prevent pollution of soil, ground water and
air, waste control and monitoring is necessary.
In developing countries, we often find rubbish fires set either
intentionally or occurring spontaneously. When PCBs are burned
in such dumps, they can break down into dioxins and other toxic
pollutants.
Moreover, in developing countries, there are people who scavenge
for usable articles from dumps or drink the milk of cows that
have grazed on grass in the area of waste dumping sites. These
people are exposed to pollutants and are at high risk of being
harmed. Waste dumping sites should be regarded as a source of
pollution and must be monitored.
