Mercury poisoning is caused by inhalating Hg 0 or eating foods polluted by IHg in a variety of industrial settings, including the chlor-alkali industry ( Hg 0 ), thermometer ( Hg 0 ) and fluorescent lamp manufacturing facilities ( Hg 0 ), as well as chemical processing ( Hg 0, IHg), and dental practices ( Hg 0 ). Epidemiological data show that mercury poisoning mainly results from occupational contact with mercury, abuse of mercury-containing compounds, or the use of skin-lightening cosmetic products. The levels of urinary Hg and MeHg in the majority of the general public in China were below the reference value set by the Chinese health authority, except for a few mining areas, due to abundant food resources and low concentration of methylmercury in inland cultured fish. People showed different clinical manifestations when exposed in different ways to different forms of mercury, such as Hg vapour (Hg 0) target damage the brain and kidney, inorganic Hg (IHg) target damage the kidney, and organic Hg (OHg, assumed to be methylmercury MeHg) target damage the brain. Mercury (Hg) poisoning has been a major public health in the world. Regulation of skin-lightening cosmetic products, safety surveillance of CFRs, and prevention and control of occupational exposure must be improved to decrease the incidence of mercury poisoning in China. Furthermore, among 18 patients with NS, 15 had normal urine protein and serum albumin levels after 22.67 ± 10.26 months. Third, follow-up data shows that 13 patients with EMG-confirmed neurological injury, 10 showed full recovery after 38.50 ± 8.03 months. However, the NS caused by CFRs is mainly membranous nephropathy and the probability of peripheral neuropathy caused by CFRs is higher than other pathogens. The complications of occupational and cosmetics-induced mercury poisoning are consistent with international belief. Mercury poisoning-induced Nephrotic syndrome (NS) and peripheral neuropathy are common long-term complications. Second, the most common symptoms were nervous system (50.3 %), kidney (16.4 %) and breathing (8.0 %). Resultsįirst, mercury poisoning in China mainly occurred through occupational exposure and the inappropriate use of mercury-containing cosmetics and Chinese folk remedies (CFRs). Patient characteristics were evaluated by statistical and correlation analyses. Methodsĭata for 288 mercury poisoning patients were collected at our hospital from July 2014 to September 2019, including sex, age, admission time, blood mercury content, urine mercury content, creatinine, urinary mercury/creatinine ratio, 24-h urinary protein levels, electromyography (EMG) findings, renal biopsy, and follow-up. This study investigated the epidemiology, clinical manifestations, treatment, and follow-up of Chinese patients with chronic mercury poisoning. There are no reports on the incidence of chronic mercury poisoning in a large population in China.
