Photostability and toxicity of pentachlorophenol and phenanthrene

Historical Long-term Exposure to Pentachlorophenol Causing Risk of Cancer - A Community Study

“…People were undertaken the agricultural work which provided the opportunity to directly expose to PCP. Especially, when PCP is exposure to intense solar radiation, it could result to even greater toxicity and carcinogenicity (Agbo et al, 2011). There was one cohort study had similar result with us, it reported increased risk of leukemia associated with people directly exposing to PCP in occupational workers (Ruder et al, 2005).…”

Mineralization of pentachlorophenol by ferrioxalate-assisted solar photo-Fenton process at mild pH

“…1, direct solar photolysis had no effect on TOC abatement for 120 min. This agrees with the low photodegradation rate constants at PCP concentrations of 0.4-2.1 mg/L, within the range of 4.9×10 -2 -7.1×10 -2 h -1 , which informs about the great persistence of this pollutant in the environment (Agbo et al, 2011). The PCP mineralization by conventional Fenton process with 2 mM H2O2 was also very inefficient due to the low Fe(II) dosage (i.e., 5 mg/L) and the expected Fe(III) precipitation at pH 5.0.…”
