Environmental chemistry of pentachlorophenol
TLDR
Although commercial PCP can be partially purified, the toxicity and mobility of both the parent compound and its impurities suggest that indiscriminate use of PCP products and the exposure of humans and domestic animals should be minimized.
Abiotic processes influencing fipronil and desthiofipronil dissipation in California, USA, rice fields

  • 1 May 2001
TLDR
The desthiofipronil observed in field water was formed photochemically from fipronsil, accumulated due to slower photolysis and lack of volatility from water, but eventually dissipated.
Pesticides as environmental mutagens.
TLDR
This chapter explores the validity of the assumption that almost every pest-control chemical is a “potential mutagen” or "potential carcinogen" and presents an environmental view which modifies but does not entirely overcome it.
The photochemical generation of hydrogen peroxide in natural waters
The photochemical formation of hydrogen peroxide in tryptophan solutions and natural waters was monitored by a sensitive spectrophotometric assay. Peroxide was characterized by ion exchange

  • 1 March 2001
TLDR
Little is known of the environmental fate of the aryltriazolinone herbicide carfentrazone-ethyl (compound I), but Rice field applications of Shark 40D commercial formulation to duplicate 5.7 m2 rings produced pseudo-first-order half-lives of 6.5 to 11.1 h in water and 37.9 to 174 h in sediment.
Environmental fate of rice pesticides in California.
TLDR
Each of the pesticides reviewed is reported to dissipate from field water after application, and its aerobic biodegradation is rapid and follows the same routes as with molinate.
