摘要: We conducted a study to investigate the relationship between exposure cyanobacteria and microcystins incidence of symptoms in humans living close proximity lakes affected by cyanobacteria. The design was prospective residents around three (Canada), one which has water treatment plant supplying potable local residents. Participants had keep daily journal record contact (full or limited) with body. Samples were collected document microcystin concentrations. Symptoms potentially associated (gastrointestinal: 2 indices (GI1: diarrhea abdominal pain nausea vomiting; GI2: vomiting [nausea fever] [abdominal cramps fever]); upper lower respiratory tract; eye; ear; skin; muscle pain; headaches; mouth ulcers) examined relation using Poisson regression. Only gastrointestinal recreational contact. Globally, there significant increase adjusted relative risk (RR) higher cyanobacterial cell counts for GI2 ( 100,000 cells/mL: RR=3.28, 95% CI=1.69-6.37, p-trend=0.001). In participants who received their drinking supply from whose source contaminated cyanobacteria, an (RR=5.16; CI=2.93-9.07) RR=3.87; CI=1.62-9.21; RR=2.84; CI=0.82-9.79), skin (RR=2.65; CI=1.09-6.44) ear (RR=6.10; CI=2.48-15.03) observed. population should be made aware risks A management plan is needed plants that draw
