Exposure scenarios and guidance values for urban soil pollutants.

In general, risk assessments of urban soil pollution are prepared by comparing the levels of pollutants with soil quality criteria. However, large urban areas are contaminated with concentrations of pollutants far exceeding the existing soil quality criteria and would consequently be considered to be of potential risk to humans. This is, however, a rather rigid approach, and for risk management purposes it would be desirable to have more than just one level of soil quality criteria.

Ultrasonic testicular texture and size in 444 men from the general population: correlation to semen quality.

Scrotal ultrasonography was performed in 888 testes of 444 randomly selected men appearing before the medical board prior to military service (Mili group, 287 men, median age 18.8 years), and in employees from an industrial company (Empl group, 157 men, median age 35.6 years).

Waterborne paints. A review of their chemistry and toxicology and the results of determinations made during their use.

This work presents information on the composition of waterborne construction paints used in Denmark, data from determinations of chemicals evaporating from paints applied with a brush or roller, and the toxicology of these chemicals. Seven product types were selected to illustrate the composition of the paints. Measurements at two workplaces were used as models for the work environment during painting.
