Contract award notice: Acquisition of a gc-ms / ms system for the analysis of pcbs, Pesticides, Pahs and chlorobenzenes
and its subsequent maintenance for a period of 4 years
Despite all benefits from the utilization of sewage sludge in agricultural systems, care must be taken, because this waste may have in its composition high concentrations of organic contaminants, such as chlorobenzenes
Biological responses of maize (Zea mays) plants exposed to chlorobenzenes

that are not produced on a large scale include m-dichlorobenzene, tetrachlorobenzenes, trichlorobenzenes and hexachlorobenzene.
In particular, the widespread presence of these compounds over the past five decades has been related to the production and degradation of numerous agricultural pesticides and insecticides such as chlorobenzenes
and chlorinated cyclohexanes, which end up contaminating the soil and polluting ground waters.
It was also noted that micro-biological transformations of chlorobenzenes
, chlorinated phenoxyacetates and chlorobiphenyls result in chlorocat-echols formation .
The handbook describe how to extract organic compounds from soil prior to analysis and how to test for hydrocarbons, chlorine, halogen, nitrogen, sulphur, phosphorous, volatile organic compounds, insecticides and herbicides, chlorobenzenes
, lead, and mercury in different mediums.
(CBs) are used in engine-block cleaners, solvents, pesticides, pharmaceutical intermediates and for the synthesis of chlorophenols and disinfectants.
Illustrated handbook of physical-chemical properties and environmental fate for organic chemicals: Monoaromatic hydrocarbons, chlorobenzenes
The Eastland Woolen Mill, which occupied about 250,000 square feet, reportedly used chlorobenzenes
as part of its wool dye process starting in the 1960s.
Greenpeace and other organisations, including the CSE, have found high concentrations of chlorobenzenes
and volatile and semi-volatile organochlorines, as well as metals such as chromium, copper, nickel, lead, zinc and mercury in the local water and soil.
