The effect of the linear alkylbenzene sulfonate, sodium-dodecyl-sulfonate (SDS), on the bioaccumulation of Al, Sr and Mn by Brassica oleracea and Solanum tuberosum

The hyper-eutrophic conditions in impoundments used for irrigation around South Africa’s major cities promote the co-existence of linear alkylbenzene sulfonate (LAS) and other pollutants such as metals. combined effects LAS metals, when water is to irrigate crops, has not been properly investigated light human health risks prevailing local conditions. To understand potential risks, pot-culture experiments were conducted assess effect LAS, sodium-dodecyl-sulfonate (SDS), on accumulation aluminum (Al), manganese (Mn) strontium (Sr) Brassica oleracea (cabbage) Solanum tuberosum (potato) plants. plants watered with dam containing 3.48 mg‧L−1 (sodium dodecyl sulfonate) Mn (0.257 mg‧L−1), Al (0.6 mg‧L−1) Sr (0.16 determined by field surveys, 20 days. presence SDS at environmentally relevant concentrations did enhance uptake Sr, Mn, two plants, demonstrated statistically insignificant differences means treatments (with without SDS). In addition, high pH, EC cyanotoxins affect total chlorophyll growth These findings imply that levels anionic surfactants SDS, metals contaminants reservoirs pose little risk crop yields, quality crops health, due possible these irrigated Despite study reporting no immediate inherent continuous monitoring water, soil recommended since conditions, factors can quickly change if management catchment does improve near future.
