Contamination Sources



Waste & Pollution

As the urban population is growing globally and this effect is coupled with increasing consumption, waste management has become one of the most serious environmental challenges in urban areas, with adverse effects on the quality of life, human health, environmental and natural resources, and economic and social development. It is important to know the composition of a load of waste before it is send to landfill. On the other hand, only through developing an intimate understanding of the chemistry of organic chemicals can their eventual remediation be realized.

TOC in waste

Landfills are classified according to whether they can accept hazardous, non-hazardous or inert wastes. In waste management, TOC acts as a measure for contamination with organic compounds and is also used to perform quality control (QC) checks on industrial materials such as fly ash, cement, and kaolin. Also if you evaluate the recycling of residues – there is no way around TOC.

Temperature-dependent carbon fractions

The differentiation between two carbon fractions (TIC and TOC) could be insufficient as biologically inactive, residual oxidizable carbon is determined in the same fraction as TOC. When evaluating solid wastes, elemental carbon (ROC) should be determined separately, since there is no need to restrict the load of ROC to landfills. An alternative method for the determination of elemental carbon is temperature ramping as elemental carbon requires higher combustion temperatures compared to organically-bound carbon, which is realized by the soli TOC cube.

Sources and fate of contamination

Stable isotope analysis has the power to deliver unparalleled insight into the complex interactions of organic pollutants in the environment. It can elucidate the often complex sources and fates of pollutant chemicals on land and at sea, aiding remediation strategy and shaping waste and resource management policy for protection of the environment. Developing our understanding of these processes aids our stewardship of the natural world to ensure that future generations enjoy the same wonders that we do today.
