Research Interest: Effects of butadiene and its metabolites on the somatic and germ cells of rodents, in vitro study on the effects of genotoxins and reproductive toxins in human lymphocytes and sperm, flavonoids modulate comet assay responses to food mutagens in human cells. She worked on male-mediated F1 effects in mice exposed to X-rays or chemicals or to a combination of both agents, estimated mutagenic effects induced in somatic and germ cells of laboratory mice (in vivo tests) after combined action of X-rays and chemicals occurring in the environment. She studied the antioxidants properties of flavonoid and catalase on the DNA damage induced in human sperm by thyroid hormone and noradrenaline. She was involved in biomonitoring studies of DNA damage measured by comet assay in leucocytes of blood donors and in sperm of pregnant women’s partners. Recently, she worked on the effects of phthalates on the male germ cells and the development of the offspring of males treated before mating. Moreover, she studied the effect of subchronic exposure to low doses of X-rays and endocrine disruptors on the quantity and quality of spermatozoa as well as the effects on the pre- and postnatal surviving and development of the offspring of exposed males. She studied the DNA damage in leucocytes of nuclear medicine workers. Presently, she studies the radioprotective effect of resveratrol and lycopene against the damage induced by irradiation in germ and somatic cells of mice.

Isidro A. Pérez is Associate Professor of Applied Physics at the University of Valladolid. His scientific career began with measurement and modelling of photochemical oxidants. The following research line was the management of RASS sodar data, which led to different papers. This device analyses the low boundary layer beyond the heights investigated by any meteorological tower. After that, CO2 concentrations were studied at a rural site and several papers that combined RASS sodar observations with concentrations measured present the results of this research. Moreover, parametric and nonparametric procedures were used to investigate the daily and annual cycles of greenhouse gases. The analysis of air parcel trajectories was later considered and the contrast between Atlantic and continental trajectories was observed on the greenhouse gas concentration recorded. Finally, his research is oriented towards the trend determination by parametric and nonparametric procedures and the origin of greenhouse gas outliers and their influence on this trend.

Research Interest:  Low atmosphere meteorology; Air pollution; Statistics of meteorological observations
