Selected features of breast and peritoneal cancers diagnosed in carriers after risk-reducing salpingo-oophorectomy.

Background: Since more than two decades Risk-reducing salpingo-oophorectomy (RRSO) is recommended and widely accepted by BRCA1/2 carriers as a method reducing ovarian cancer risk and improving survival rate. After RRSO, there remains a risk of breast cancer and peritoneal cancer. The characteristics of these neoplasms are not well known.

Toxicity and chemical analyses of airport runoff waters in Poland.

The aim of this study was to assess the ecotoxicological effects of various compounds in complex airport effluents using a chemical and ecotoxicological integrated strategy. The present work deals with the determination of sum of PCBs, PAHs, pesticides, cations, anions, phenols, anionic, cationic, non-ionic detergents, formaldehyde and metals--as well as TOC and conductivity--in runoff water samples collected from 2009 to 2011 at several locations on two Polish international airports. Two microbiotests (Vibrio fischeri bacteria and the crustacean Thamnocephalus platyurus) have been used to determine the ecotoxicity of airport runoff waters.

Application of physicochemical data for water-quality assessment of watercourses in the Gdansk Municipality (South Baltic coast).

The paper presents water-quality evaluation based on an 8-year monitoring programme in the Gdansk Municipality region, on the Southern coast of the Baltic Sea. The studies were carried out from 2000 to 2007 by surface water analysis at 15 various sites within eight watercourses. Sampling sites included rather urbanized or developed lands, farming fields and non-polluted city recreational areas such as parks and forests.

Bioaerosols on Tri-city (Gdańsk-Sopot-Gdynia) beaches.

Bioaerosol formation is an important process of mass and energy exchange between the sea and the atmosphere by means of droplets of marine dust. Studies of marine aerosol activity developed in the last decades of the 20th century. Those studies revealed that concentrations of bacteria in aerosol droplets were hundreds of times higher than were those measured in superficial marine waters.
