Sulfonamides (SA) are a class of antibiotics routinely found in environmental matrices and therefore their role as contaminants should be investigated in non-target organisms. With this purpose the present experimental work has evaluated the exposure of the chlorophycean Ulva lactuca L. to sulfathiazole (STZ), a SA drug commonly used in aquaculture, at two concentrations representing prophylact...

Emerging pollutants impose a high degree of stress on marine ecosystems, compromising valuable resources, the planet and human health. Pharmaceutical residues often reach their input is directly related to activities. Fluoxetine an antidepressant, one most prescribed selective serotonin reuptake inhibitors globally has been detected in aquatic ecosystems concentrations up 40 ?g L ?1 . The prese...

Increased nutrient inputs to temperate coastal waters have led to increased occurrences of macroalgal blooms worldwide. To identify nutrients that are limiting to macroalgae and to determine whether different forms of these nutrients and long-term ambient nutrient conditions affect macroalgal response, we used in situ enrichment methods and tested the response of 2 bloom-forming species of macr...

Four seaweed polysaccharides were extracted from Sarcodia ceylonensis, Ulva lactuca L., Gracilaria lemaneiformis, and Durvillaea antarctica, respectively, by microwave-assisted extraction. The effect of three significant variables (extraction time, extraction temperature, and the ratio of water to raw material) on the process for extracting polysaccharides was investigated, along with the optim...

Ulva lactuca is one of the green seaweeds that widely developed as a cosmetic preparation. U. has potential to be used seaweed salt and residue can body scrub preparation material. In addition, natural ingredients for preparations are turmeric (Curcuma longa) rhizome. This study aimed determine optimum formulation best physical characteristics (U. lactuca) (C. rhizomes. was experimental with fo...
