Risk management for arsenic in agricultural soil–water systems:lessons learned from case studies in Europe

Abstract Chronic exposure to arsenic may be detrimental to health. We investigated the behaviour, remediation and risk management of arsenic in Freiberg, Germany, characterized by past mining activities, and near Verdun in France, where World War I ammunition was destroyed. The main results included: (1) pot experiments using a biologically synthesized adsorbent (sorpP) with spring barley reduced the mobility of arsenic, (2) the Omega-3 Index ecotoxicological tests verified that sorpP reduced the uptake and toxicity of arsenic in plants, (3) reverse osmosis membrane systems provided 99.5% removal efficiency of arsenic from surface water, (4) the sustainability assessment revealed that adsorption and coagulation–filtration processes were the most feasible options for the treatment of surface waters with significant arsenic concentrations, and (5) a model was developed for assessing health risk due to arsenic exposure. Risk management is the main option for extensive areas, while remediation options that directly treat the soil can only be considered in small areas subject to sensitive use. We recommend the risk management procedure developed in Germany for other parts of the world where both geogenic and anthropogenic arsenic is present in agricultural soil and water. Risk management measures have been successful both in Freiberg and in Verdun

Does Returning to Work After Childbirth Affect Breastfeeding Practices?

This study examines the effect of the timing and intensity of returning to work after childbirth on the probability of initiating breastfeeding and the number of weeks of breastfeeding. Data come from the National Longitudinal Survey of Youth (NLSY79). Baseline probit models and family-level fixed effects models indicate that returning to work within 3 months is associated with a reduction in the probability that the mother will initiate breastfeeding by 16–18%. Among those mothers who initiate breastfeeding, returning to work within 3 months is associated with a reduction in the length of breastfeeding of 4–5 weeks. We find less consistent evidence that working at least 35 h per week (among mothers who return to work within 3 months) detracts from breastfeeding. Future research is needed on understanding how employers can design policies and workplaces that support breastfeeding.
