Plastic bags are versatile, lightweight and flexible, and this has led to consumers having an insatiable appetite for the consumption of plastic shopping bags. To influence consumer behaviour, the Government of Botswana ...
Abiotic and biotic factors influencing the mobility of arsenic in groundwater of a through-flow island in the Okavango Delta, Botswana
(Elsevier, https://www.elsevier.com, 2014-10-10)
The Okavango Delta of Botswana is a large arid-zone wetland comprising 20,000 km2 of permanent and seasonal floodplains and over 100,000 islands. It has been shown that island groundwater can have very high dissolved arsenic ...
