Pollution of Beach Sand From Selected Recreational Reservoirs by Microplastics

Popenda Agnieszka, Wiśniowska Ewa

Civil and Environmental Engineering Reports

Vol. 32, no. 4

230--241

The presence of microplastics have been ubiquitously confirmed in aquatic environment possessing the potential risk to the health of ecosystem. Most studies concerning microplastics are focused on water bodies, but it is considered that sediments and sands from the beaches may to be a long-term sink for microplastics. High concentrations of microplastics have been found in sand beach in Europe and all over the world. In the present studies samples of beach sand originating from three beaches of recreational reservoirs in Southern Poland (Silesian Voivodship) were analysed. Preliminary screening tests were done to evaluate the degree of microplastics pollution of the selected sandy beaches. Samples were taken once from three places on the beaches of each reservoir. Beach sections parallel to the waterline were selected at each study at the swash zone – about 1 m above the waterline. Previously, no studies were done on the presence of microplastics in these beaches. The samples taken from the beach were homogenized and mixed with saturated NaCl solutions, after separation of microplastics the pollutants were counted under optical microscope (under magnification 40 -100 x). It was found that in all three places the microplastics occurred in the beach sand samples. The most contaminated samples originated from Lisiniec recreation park (Adriatyk) which contained 340 ± 222 particles per kg/d.m. The most abundant fractions in the examined samples were fibres and fragments, the less abundant ones were granules. It can be concluded that recreational reservoirs beaches can be significantly contaminated by microplastics particles, but simultaneously the concentrations of these micropollutants can vary a lot between the individual places.

Poważny brak danych o przyczynach zanieczyszczeń rzek i kąpielisk

Opisano w jaki sposób poprzez brak ustanowienia przepisów dotyczących tak monitoringu jak i zbierania danych o zrzutach z przelewów awaryjnych kanalizacji bytowo-gospodarczej oraz sposobu przetwarzania tych informacji, doprowadzono do sytuacji w której nie jest nawet znana skala wpływu takich zrzutów na Jednolite Części Wód w Polsce. Taka sytuacja nie sprzyja planowaniu i realizowaniu inwestycji w celu zmniejszenia oddziaływania zrzutów awaryjnych na wody powierzchniowe.

It has been pointed out that the Polish law does not consider any rules of monitoring collecting and processing data on discharges from Sanitary Sewer Overflows (SSO) and on their impact on recreational waters. As the result of this gap in regulations even the scale of such accidental discharges impact on surface water quality is not known. This does not support, actions on planning; investments oriented on decreasing the total load of pollution being discharged to surface waters.
