The chemistry and meiofauna of some unpolluted Sandy Beaches in South Africa

Chemical and meiofaunal studies have been carried out on ten sandy beaches along the south and west coasts of South Africa with the aim of establishing base line levels of some parameters, including trace metals, nutrients, dissolved oxygen, oxygen absorbed from alkaline permanganate (OA), temperature and salinity and the diversity and size of meiofaunal populations. Guidelines for the normal levels of the various parameters have been set out and some reasons for their variability have been suggested. The various sites share similarities with regard to exposure, granulometry and hydrology.
