Organophosphates
Organophosphates has been studied in 2 papers since 2025: 2 observational studies in people; 2 in the past year. The newest paper, Apr 14, 2026: “Association of exposure to organophosphate pesticides with reproductive lifespan”.
“the organo-phosphate-exposed group experienced significantly more balance and memory impairments, and more pronounced neurological symptoms”
None of its findings points the other way.

What did studies of Organophosphates find?
4Studies of Organophosphates measured 4 outcomes; the most studied are CD56+CD57+ EM4 CD8+ T cells (1 study), plasma cell precursors (1) and red blood cell count (1).

Organophosphates decrease CD56+CD57+ EM4 CD8+ T cells in humans (more than 2-fold reduced).
“the proportion of CD56+CD57+ cells of the EM4 (CD27–CD28+) CD8+ T cell subset was more than 2-fold reduced”

Organophosphates increase plasma cell precursors in humans (1.5-2-fold increase).
“Lymphocyte phenotyping revealed a 1.5-2-fold increase in the relative and absolute levels of circulating plasma cell precursors with the CD19+IgD–CD27++ phenotype”
