Objective: To analyze factors influencing the underestimation of noise-induced permanent threshold shift (NIPTS) among manufacturing workers, providing baseline data for revising noise exposure standard.
Design: A cross-sectional study was designed with 2702 noise-exposed workers from 35 enterprises from 10 industries. Personal noise exposure level(L) and noise kurtosis level were determined by a noise dosimeter.

Objective: To explore the effects of noise exposure level and cumulative noise exposure (CNE) on the relationship between rs2070424 and rs10432782 SNPs in SOD1 and the susceptibility to noise-induced hearing loss (NIHL).
Methods: A case-control study was performed for investigating the effects of environmental risk factors on the susceptibility to NIHL in 201 sensitive workers and 202 resistant workers.A questionnaire was utilized to investigate the occupational health and to identify the occupational risk factors.

Objective: To observe the association between SNPs in SOD1 (rs1041740, rs2070424, rs10432782 and rs4998557) and noise-induced hearing loss in Chinese Han population.
Methods: A case-control study was used to study the effects of environmental risk factors on the susceptibility to noise induced hearing loss (NIHL) in 201 sensitive workers and 202 resistant workers. A questionnaire was designed to carry out an investigation, and an occupational health survey was used to identify the occupational risk factors.

Objective: To study the methylation of O-6-methylguanine-DNA methyltransferase (MGMT) and p16 gene in the sputum cells of radon-exposed population. To provide the experimental base for finding the molecular biomarker of the high risk population of the radon-induced lung cancer.
Methods: 91 radon-exposed workers were divided into 4 groups, high dosage group (> 120 WLM), middle dosage group (between 60 and 120 WLM), low dosage group (between 30 and 60 WLB) and lower dosage group (between 2 and 30 WLM) according to the accumulated exposure dosage of the radon daughters.
