BQ hematotoxicity to adult fish. (A) May–Grunwald/Giemsa of KM cells in BQ-exposed (right) and control (left) fish. Red arrows, erythrocytes (oval-shaped nucleus and cytoplasm); black arrows, lymphocytes (large round-shaped nucleus surrounded by minimal cytoplasm); green stars, neutrophils (segmented nucleus and cytoplasm with distinct neutral granules); yellow stars, macrophages (large irregular-shaped cytoplasm with distinct vacuoles); blue arrows, precursors (large and dense nucleus with dark cytoplasm). Scale bars: 5 μm. (B) Blood cell counts of KM in each group were calculated manually based on their morphology (Student's t-test, n=9, mean±s.d., *P<0.05, **P<0.01).
