Ecological toxicology and human health effects of heptachlor.
Fendick EA, Mather-Mihaich E, Houck KA, St Clair MB, Faust JB, Rockwell CH, Owens M. Fendick EA, et al. Rev Environ Contam Toxicol. 1990;111:61-142. doi: 10.1007/978-1-4612-3340-4_2. Rev Environ Contam Toxicol. 1990. PMID: 2403688 Review.
In vivo studies indicate that heptachlor epoxide is the predominant metabolite, formed as a product of the mixed-function oxidase system, while 1-hydroxychlordene is the major soil metabolite. For quantification, heptachlor and its metabolites are extracted from air …

Root uptake and translocation of 14C-heptachlor and its degradation products in soil by zucchini and tomato seedlings.
Hayashi O, Sugioka D, Ohyama K. Hayashi O, et al. J Pestic Sci. 2018 Nov 20;43(4):293-296. doi: 10.1584/jpestics.D18-035. J Pestic Sci. 2018. PMID: 30479553 Free PMC article.
To investigate root uptake and translocation of heptachlor and its degradates (cis-heptachlor epoxide and 1-hydroxychlordene) in soil, zucchini and tomato seedlings were transplanted to soil approximately four months after treatment with (14)C-heptachlor. ...

Degradation of the persistent organic pollutant [14C]heptachlor in Japanese field soils.
Hayashi O, Kameshiro M, Satoh K. Hayashi O, et al. Biosci Biotechnol Biochem. 2013;77(6):1240-4. doi: 10.1271/bbb.130017. Epub 2013 Jun 7. Biosci Biotechnol Biochem. 2013. PMID: 23748788 Free article.
Heptachlor was degraded mainly to cis-heptachlor epoxide by a biotic process and to 1-hydroxychlordene by an abiotic process in the field soils. Volatilization of heptachlor and cis-heptachlor epoxide from the soil was observed over the experimental period. The amou …

Metabolism of organochlorine pesticide heptachlor and its metabolite heptachlor epoxide by white rot fungi, belonging to genus Phlebia.
Xiao P, Mori T, Kamei I, Kondo R. Xiao P, et al. FEMS Microbiol Lett. 2011 Jan;314(2):140-6. doi: 10.1111/j.1574-6968.2010.02152.x. Epub 2010 Nov 18. FEMS Microbiol Lett. 2011. PMID: 21087297
A large amount of heptachlor epoxide and a small amount of 1-hydroxychlordene and 1-hydroxy-2,3-epoxychlordene were detected as metabolic products of heptachlor from most fungal cultures. ...

Heptachlor degradation characteristics of a novel strain and its application.
Qiu L, Wang H, Wang X. Qiu L, et al. Water Sci Technol. 2018 May;77(7-8):2113-2122. doi: 10.2166/wst.2018.127. Water Sci Technol. 2018. PMID: 29722697
It was also shown that strain H can grow on the degradation products of heptachlor such as 1-hydroxychlordene or heptachlor epoxide. Furthermore, additional carbon sources can accelerate the degradation rate of heptachlor because of co-metabolism. ...

Conversion mechanism of heptachlor by a novel bacterial strain.
Qiu L, Wang H, Wang X. Qiu L, et al. RSC Adv. 2018 Feb 2;8(11):5828-5839. doi: 10.1039/c7ra10097c. eCollection 2018 Feb 2. RSC Adv. 2018. PMID: 35539625 Free PMC article.
Identification of the metabolites by GC/MS showed that strain H degrades heptachlor via two pathways simultaneously, i.e., pathway (1) hydroxylation at the C1 position of heptachlor to 1-hydroxychlordene followed by epoxidation and dechlorination to chlordene epoxid …
