The occurrence of perfluorinated compounds (PFCs) in human blood is known to be widespread; nevertheless, the sources of exposure to humans, including infants, are not well understood. In this study, breast milk collected from seven countries in Asia was analyzed (n = 184) for nine PFCs, including perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA).

This paper details some of the difficulties in financing a community-based waste management (CBWM) project for the collection of waste in Siem Reap, Cambodia. It presents a series of financing scenarios based on several potential logistical arrangements.

The timeless rhythm of the Mekong

Tens of millions of people in south and southeast Asia routinely consume ground water that has unsafe arsenic levels. Using hydrologic and (bio)geochemical measurements, the researchers show that on the minimally disturbed Mekong delta of Cambodia, arsenic is released from near-surface, river-derived sediments and transported, on a centennial timescale, through the underlying aquifer back to the river.
