<p>Shoreline structures such as dock steps, jetties and slipways, which are covered at high tide and exposed by low tide are colonised by inter-tidal-algae which render the surfaces slippery. There is consequently a risk that persons, livestock or vehicles crossing them will skid or slip resulting in accidents and causing personal injury or damage to property. The inter-tidal algae can be controlled by periodic treatment with aqueous hydrogen peroxide solution having a concentration of between 2.5 and 5% w/w without leaving undesirable residuals that could enter the marine food chain and without harming local populations of beneficial invertebrates.</p> |
