Chlordane and Heptachlor Are Metabolized Enantioselectively by Rat Liver Microsomes

open access: yes, 2016
Chlordane, heptachlor, and their metabolites are chiral persistent organic pollutants that undergo enantiomeric enrichment in the environment. This study investigated the enantioselective metabolism of both chlordane isomers and heptachlor, major ...

Hematotoxicity of heptachlor [PDF]

open access: yes, 2004
Hematotoxicity has been documented in adults exposed to high levels of organochlorine pesticides. Our studies revealed that prenatal exposure to the organochlorine pesticide heptachlor resulted in alteration of lymphocyte development, while myeloid cell ...

Identifying Gene Predictors of Chemicals Linked With Breast Cancer: A Machine Learning Analysis of MCF7 Cellular Transcriptomic Screening Data

open access: yesEnvironmental and Molecular Mutagenesis, Volume 66, Issue 8, Page 425-441, October 2025.
ABSTRACT Breast cancer is the most prevalent cancer in women and has been linked to exposure to environmental chemicals. However, many chemicals have not been evaluated for relationships with this outcome. In this study, we analyzed RNA sequencing data from human breast cancer‐derived MCF7 cells exposed to hundreds of individual chemicals.

Reducing uncertainty in dose–response assessments by incorporating Bayesian benchmark dose modeling and in vitro data on population variability

open access: yesRisk Analysis, Volume 45, Issue 2, Page 457-472, February 2025.
Abstract There are two primary sources of uncertainty in the interpretability of toxicity values, like the reference dose (RfD): estimates of the point of departure (POD) and the absence of chemical‐specific human variability data. We hypothesize two solutions—employing Bayesian benchmark dose (BBMD) modeling to refine POD determination and combining ...

Photocatalytic removal of aldrin and dieldrin using graphene oxide and TiO2‐doped CuFe2O4

open access: yesJournal of Chemical Technology &Biotechnology, Volume 100, Issue 1, Page 138-154, January 2025.
Abstract BACKGROUND Conventional treatment processes and existing photocatalysts have proven insufficient in efficiently removing aldrin and dieldrin. Consequently, this study aimed to investigate the removal of aldrin and dieldrin from surface water using a titanium dioxide/graphene oxide/copper ferrite (TiO₂/GO/CuFe₂O₄) nanocomposite.
