    Contamination of Legionella pneumophila in metro cooling tower water and its influencing factors in a city by Rong PENG, Bin SHI, Huaiji WANG, Junling LIU, Fang WANG

    Published 2024-12-01
    “…For each unit increase in ln-transformed nitrates and sulfates, the βs (95%CIs) of Legionella pneumophila concentration were −1.17 (−1.59, −0.74) and −1.11 (−1.63, −0.58), respectively. Compared with the group with 0-0.04 mg·L−1 of free residual chlorine, the β (95%CI) was −5.66 (−9.45, −1.87) for the group with ≥0.31 mg·L−1 of free residual chlorine. …”
