(i) Ten biological toxicity events were common to four NFPA subtypes (NF-, LH-, FSH-, and LH/FSH-), including cardiac arrhythmia, liver hypertrophy, renal inflammation, renal nephritis, cardiac pulmonary embolism, cardiac stenosis, increased levels of bilirubin, kidney failure, increased levels of potassium, and glutathione depletion in liver. Here, PLOD1 is linked to cardiac rhythm disease.
