“…CA has also been found in landfill leachate at concentrations of several hundred mg/L possibly due to leaching from fire retarded products (Ying et al, 1986). It also exists in the environment as a degradation byproduct of certain pesticides, namely dieldrin, heptachlor and endosulfan (Cochrane and Forbes, 1974;Ali et al, 2016).…”

Persulfate-based in situ chemical oxidation (ISCO) involves the injection of persulfate (S2O8 2-) into the subsurface to remediate contaminated groundwater and soils. Although S2O8 2does not react with contaminants to an appreciable extent, it can be activated into stronger oxidants (e.g., SO4 • and • OH) by heat, alkaline solutions, dissolved iron and ironcontaining minerals. The objective of the research described in this thesis is to explore the influence of temperature and background solutes on contaminant transformation by heat-and mineral-activated S2O8 2-. Through the transformation of benzoic acid (a model organic compound) and chlorendic acid (a flame retardant), it was discovered that temperature affects not only the rate of contaminant transformation but also the transformation pathway and distribution of byproducts. Solution pH, alkalinity, and chloride also influence the rates of persulfate activation and contaminant degradation.These novel understandings may help improve the design and operation of S2O8 2--based remedial systems.

Publications from 1969 through 1974 reporting organic and spark source mass spectrometric studies on environmental samples have been compiled. Emphasis is placed on pollutants identified, but some methods and techniques are discussed. The 396 reports cited vary from those reporting hundreds of identified pollutants to those describing the analysis of only one sample containing one or a few pollutants. Reports concerning forensic, synthetic and standard samples, and analyses for drug residues. metabolites and degradation products are not included
