Regional differences in levels of chlorinated and brominated pollutants in mother's milk from primiparous women in Sweden.

Early life exposure to halogenated persistent organic pollutants, such as polychlorinated biphenyls (PCBs), the DDT metabolite p,p'-dichlorodiphenyldichloroethane (p,p'-DDE), polybrominated diphenylethers (PBDEs), and hexabromocyclododecane (HBCD), may affect human health. We determined if there are regional differences in mother's milk levels of these compounds in Sweden. In year 2000-2004, milk was sampled from 204 randomly recruited primiparas from four regions of Sweden.

Ocular and airway symptoms related to organic acid anhydride exposure--a prospective study.

Background: Organic acid anhydrides (OAA) are used as hardeners in epoxy resin systems. They are powerful sensitizers giving frequent rhinitis and asthma in exposed workers. Incidence of symptoms is unknown.

Association of HLA-DQ5 and HLA-DR1 with sensitization to organic acid anhydrides.

Background: Organic acid anhydrides are low molecular weight industrial chemicals, able to cause rhinoconjunctivitis and asthma associated with specific IgE against hapten-carrier protein conjugate. Only a proportion of exposed workers develop IgE-associated allergy to acid anhydrides.

Objective: We determined whether genetic susceptibility, in particular, HLA Class II alleles may be a risk factor.

Monitoring of cadmium in the chain from soil via crops and feed to pig blood and kidney.

The relationships between cadmium (Cd) levels in soil, feed crops, feed concentrate, pig feed mixture, water, pig blood, and kidney from 49 farms were investigated and the possibility to use pig kidney as a bioindicator of available Cd in the agricultural environment was evaluated. There were correlations between Cd levels in soil and wheat, between wheat and barley, and between feed and kidney. The accumulation ratio between Cd levels in feed and kidney was on average 3.

Cadmium in blood and urine--impact of sex, age, dietary intake, iron status, and former smoking--association of renal effects.

We studied determinants of cadmium status and kidney function in nonsmoking men and women living on farms in southern Sweden. Median blood Cd (BCd) was 1.8 nmol/L (range, 0.
