Synopsis

On request of the Inspectorate of the Environment, district Zeeland, five samples have been investigated. Two samples contained red deposits, these deposits turned out to consist of the red coloured alga Haematococcus pluvialis. A third water sample, in which white colourless crystals occurred, contained only relatively low concentrations of calcium, sodium, sulphate and some nitrate. A leave sample of Brussels sprout plants was analysed for lead, cadmium, arsenic, copper and zinc. The concentrations were at the level found for not polluted sprouts. In conclusion it can be stated that pollution of the local environment caused by air transport of the contaminants mentioned is unlikely.
