Reduction of sperm production by diesel exhaust gas 1998.10.15

The research of Tokyo University of Science revealed that there is a toxic damage to the reproductive function of the living thing in the exhaust gas of the diesel car. Experiments with mice, about twice the atmospheric concentration of diesel exhaust gas around the road with heavy traffic, the particle concentration per the Air 1 Legislative meter 0. The sperm production capacity decreased by 21% by 3mg, and 53% in about 20 times and halved. From this data, the research team has a minimum concentration of 0.02 mg that does not affect sperm production capacity.
