This month in EHP
The January issue of Environmental Health Perspectives (EHP) looks at the challenges of maintaining hygiene to fight waterborne diseases during emergency situations, and extending regulation of dietary arsenic beyond drinking water by setting a limit for arsenic in rice.
The WASH Approach: Fighting Waterborne Diseases in Emergency Situations
Emergency situations are ripe for outbreaks of diseases spread by fecal–oral transmission. In times of scarcity, water tends to go first to drinking and cooking, and hygiene become a lower priority. But health-protective behaviors are critically important for preventing the spread of waterborne diseases.
In Search of “Just Right:” The Challenge of Regulating Arsenic in Rice
Numerous studies have assessed the health impact of consuming arsenic through drinking water, and many countries regulate arsenic in municipal water. Now research and regulatory concerns are broadening to include arsenic in the diet, especially in rice, but settling on an appropriate limit for arsenic in rice is proving difficult.
