Research on the pollution of persistent organic compounds
(POPs) has been receiving the attention of many scientists all around
the world. The assessment of pollution levels and emissions of dioxinlike chlorobenzene compounds such as hexaclobenzene (HCB),
Pentaclobenzene (PeCB), tetrachlorene (TeCB), triclobenzene (TCB),
diclobenzene (DCB) is the scientific basis for countries. Participating
in signing the Stockholm Convention to implement the plans for
management, disposal and environmental pollution treatment by POPs
well. In Vietnam, the focus is mainly on studying U-POPs such as
dioxin, furans and PCBs in soil, sediment, organisms and human.
Disclosures related to unintentional emissions of chlorbenzen
compounds into the environment from industrial manufacture and
waste disposal in Vietnam are limited.
From above problems, it is necessary to research into the
overall sources of emissions and the level of environmental pollution
caused by the sources of industrial waste of chlorbenzenes, optimizing
the efficiency of the process analysis in accordance with conditions in
Vietnam. This is a topical issue in current conditions when health and
environment in Vietnam are at an alarming level. Therefore, I decided
to choose the topic “Study to determine the content of some
chlorbenzen compounds from unintentional emission sources in
industrial zones in Thai Nguyen province”, contributing to the
protection and sustainable development of ecological environment in
Thai Nguyen province
